10 Common Signs of an Unhealthy Gut – and 5 Proven Strategies to Help

Millions of people have gut health problems.

Common signs of an unhealthy gut include bloating, indigestion, heartburn, constipation, and diarrhea.

However, gut health problems can also lead to lesser-known symptoms like sleep problems, sugar cravings, depression, anxiety, and skin rashes.

Today, we’re highlighting some of the most common signs of an unhealthy gut – and 5 proven strategies you can use to support gut health.

1) Constipation, Diarrhea, Bloating, and Other Irritable Bowel Syndrome (IBS) Symptoms

We’ll start with obvious gut health problems: if you regularly experience constipation, diarrhea, bloating, and other IBS symptoms, then it could be a sign of poor gut health. These issues are not normal, and they could be a sign of IBS or other diagnosable gut health conditions.

2) Skin Irritation, Rashes, Psoriasis, and Other Conditions

Have you noticed skin rashes, acne, and other visible signs of skin problems in recent years? It could be a sign of gut health. Many skin conditions are traced back to bacteria in your gut. If you have an excessive balance of bad bacteria relative to good bacteria, then it could increase your risk of psoriasis and other skin conditions.

3) Autoimmune Conditions

Some research suggests around 70% of your immune system is linked to your gut. Your gut plays a critical role in immunity. It can prevent negative substances from entering your body, filter problematic ingredients out of your body, and ensure your immune system functions optimally. Over time, poor gut health can lead to chronic inflammation, which increases the risk of autoimmune conditions. Autoimmune conditions occur when your body attacks itself instead of harmful pathogens. Common autoimmune conditions include celiac disease, Graves disease, rheumatoid arthritis, multiple sclerosis, and type 1 diabetes.

4) High Stress

Do you have a stressful life? Have you recently faced stress in your personal or professional life? High stress could worsen gut health. And, poor gut health could make stress worse. As your body becomes more stressed, it impedes digestion. As your digestion becomes worse, you become more stressed as your body struggles to absorb nutrients and break down the foods you’re eating. Over time, poor digestion is also linked to depression, anxiety, and other conditions.

5) Cravings for Sweet, Sugary, Fatty, or Unhealthy Foods

Do you frequently crave sweet, sugary, or fatty foods? Don’t blame poor self-control; instead, many people have excessive cravings because of gut health issues. Some people experience sugar cravings because of gut health problems, for example. Imbalanced gut microbiota can encourage you to reach for unhealthy foods in your kitchen.

6) Unexplained Weight Gain or Weight Loss

Have you lost or gained weight recently without a significant change to your diet or exercise program? Poor gut health may be to blame. Some unexplained weight gain and weight loss is linked to poor gut health. Your body may be struggling to absorb nutrients from the foods you eat. Or, leaky gut could cause excessive toxins to enter your body, making it harder to lose weight.

7) Fatigue, Low Energy, or Sluggishness

Gu health problems can lead to energy issues. If you frequently feel tired, have excessive lethargy, or lack motivation throughout the day, then your gut could be at fault. Your gut may be struggling to process food into energy, for example. Or, it could be spending so much energy digesting your food that there’s little energy leftover for you.

8) Difficulty Sleeping

If you have bad gut health, you’re more likely to have a bad sleep. Poor gut health makes it difficult to fall asleep, stay asleep, and enjoy a restful sleep. You might wake up in the middle of the night due to poor gut health. Or, you could fail to enter the deep sleep or REM cycles of sleep because of your gut health problems.

9) Mood Imbalances & Irritability

Your gut health plays a crucial role in mood. If you’ve been struggling with mood imbalances, irritability, or other issues lately, then your gut could be to blame. Your gut plays a critical role in your sense of wellbeing. Multiple studies have shown a connection between gut health, depression, anxiety, and fatigue.

10) Chronic Fatigue, Depression, Anxiety, and Other Unexplained Mood Disorders

If your mood issues progress to a point where you’re dealing with chronic fatigue, depression, anxiety, and other unexplained disorders, then gut health could be to blame. Many people with depression and anxiety have perfectly healthy guts. However, numerous studies have connected gut health to depression, anxiety, and other disorders.

5 Science-Backed Ways to Support Your Gut

You can support gut health using various proven strategies. Although serious gut disorders require medical diagnosis and treatment, you could support gut health by eliminating certain foods, taking specific supplements, and drinking more water, among other strategies.

Here are some of the best, most science-backed ways to support your gut:

Eat Probiotic-Rich Foods: Probiotic supplements are more popular than ever. However, many experts recommend focusing on probiotic-rich foods instead of probiotic supplements. Kimchi, kefir, sauerkraut, kombucha, and yogurt are all rich with billions of colony forming units (CFUs) of probiotic bacteria. Your gut needs these bacteria to break down the food you eat, extract their nutritional value, and maintain regular digestion.

Eat More Prebiotics: 95% of Americans don’t get their daily recommended intake of fiber. That’s a problem, because fiber is a valuable prebiotic. Your body needs fiber to fuel the probiotic bacteria in your gut. Eat more vegetables, fruits, and whole grains to supply your gut bacteria with the prebiotic fuel needed to support good digestion.

Drink More Water: Many people experience relief from certain gut health symptoms just by adding more water to their diet. This tip is particularly important if you drink a lot of soda, coffee, supplement drinks, or other beverages. In many cases, your gut simply need water to support good digestion.

Eat Slowly: Your digestive system can only process so much food at once. If you chew slowly, you give your gut more time to catch up to your mouth. Eating slowly breaks food into slower parts. Studies also show eating slowly can lower the risk of obesity and similar conditions.

Consider Seeing a Doctor: Sometimes, you do everything right but still experience symptoms of gut health problems. Consider seeing a doctor for gut health recommendations from a medical professional. The gut health problems listed above could be signs of a serious condition.

Final Word

Your gut health is crucial for overall health. From immunity to skin health to energy to mood, your gut is more valuable than you may think.

Learn to spot symptoms of gut health before they become serious. By spotting gut health issues today, you can tackle them as soon as possible.

How Calcium Deficiency Works: Signs & Symptoms

You have more calcium in your body than any other mineral. However, millions of people are still deficient in calcium.

Calcium deficiency can lead to issues with the strength of your teeth and bones. Calcium is also crucial for tissues and muscles, your cardiovascular system, hormones, and more.

If you aren’t getting your daily recommended intake of calcium, or if you have an absorption issue, then you may develop calcium deficiency.

Keep reading to discover everything you need to know about how calcium deficiency works, including signs and symptoms of calcium deficiency.

How Calcium Deficiency Works

If you have low levels of calcium, then you may develop a condition called hypocalcemia. Your blood has low levels of calcium, which could lead to various physical and cognitive symptoms.

Low calcium levels are associated with problems with your muscles, bones, and teeth.

Some people also develop mental health issues because of calcium deficiency. People who are deficient in calcium may have a higher risk of depression, mood changes, and irritability.

Some are deficient in calcium without knowing it. There are no early symptoms of calcium deficiency.

Over time, however, calcium deficiency leads to less and less bone density. This condition is called osteopenia. If you ignore osteopenia over time, it leads to osteoporosis. Your bones are more brittle, and you have an increased risk of fractures and breaks.

What Causes Calcium Deficiency?

Calcium deficiency is one of the few nutritional deficiencies not typically caused by dietary issues. Even if you get enough calcium in your diet, you could be calcium deficient because of health conditions and other reasons.

According to the National Institutes of Health, most people develop calcium deficiency because of:

  • Kidney failure
  • Removal of the stomach
  • The use of certain medications, including diuretics

If you fall into one or more of the above categories, then you may have a higher risk of developing calcium deficiency regardless of your diet.

It’s unclear how common calcium deficiency is. However, researchers believe calcium deficiency is more common in postmenopausal adults, people with amenorrhea (the absence of menstruation), people who are lactose intolerant, and vegetarian and vegans.

One 2015 study found 3.5 billion people were at risk of calcium intake due to low dietary intake of calcium, which would make calcium deficiency one of the world’s most common nutritional deficiencies.

According to researchers in the United Kingdom, calcium deficiency is more common in people who have chronic illnesses. Certain chronic illnesses could impede your body’s ability to absorb calcium, making it harder to get the calcium you need every day even when following good dietary practices.

Symptoms of Calcium Deficiency

You may experience physical and cognitive symptoms because of calcium deficiency. Common symptoms of calcium deficiency include:

  • Muscle aches, spasms, and cramps
  • Fatigue
  • Dry, brittle skin
  • Coarse, dry, or brittle hair
  • Brittle bones
  • Dental problems, including tooth decay, brittle teeth, and irritated gums
  • Depression and mood disorders
  • Numbness or tingling in the extremities or around the mouth
  • Pain in the arms and thighs when walking or moving

If left untreated over time, calcium deficiency can lead to more serious health issues like convulsions, arrhythmia (irregular heart patterns), and even death.

How to Target Calcium Deficiency

The best way to target calcium deficiency is to adjust your diet, take a calcium supplement, or talk to a doctor about managing medications and health conditions.

Some of the best calcium-rich foods to consider adding to your diet include:

  • Milk
  • Yogurt
  • Cheese
  • Broccoli
  • Spinach
  • Soy milk
  • Tofu
  • Beans
  • Nuts and seeds (particularly almonds and sesame seeds)

Dairy products are among the best sources of calcium, which is one reason why vegans have a higher risk of calcium deficiency. However, there are also plenty of plant-based sources of calcium.

Avoid Taking Too Much Calcium

Taking too much calcium is a problem. It leads to hypercalcemia, or an excessive buildup of calcium in your body.

Hypercalcemia can increase the risk of heart disease and kidney stones (kidney stones are lumps of calcium that build up in your kidney), among other health problems.

Talk to a doctor to find the optimal dose of calcium based on your unique physiology.

You may have a higher risk of hypercalcemia if you are also deficient in vitamin D. Vitamin D is crucial for helping your body manage calcium intake. If you don’t get enough vitamin D (say, through sunlight, supplements, or dietary sources), then you may have a higher chance of developing hypercalcemia.

Final Word: Order a Blood Test Today to Check for Calcium Deficiency

Many people are deficient in calcium but have no symptoms. That’s why blood testing is important.

However, a conventional blood test compares your results against a random selection of people who recently visited that clinic.

With our Science Based Nutrition blood testing at Science Nutrition Lab, you get a blood test comparing your results against an optimal range. A board-certified doctor reviews your results with you, helping to spot changes in your blood before symptoms appear.

Symptoms of Magnesium Deficiency & How Magnesium Deficiency Works

If you have fatigue, weakness, a low appetite, or jitters, then it could be linked to magnesium deficiency.

Although rare, millions of people worldwide have a magnesium deficiency.

Older adults, alcoholics, and people taking certain medications have a higher risk of magnesium deficiency.

Magnesium is crucial for nerve function and countless other bodily systems. If you aren’t getting your recommended dietary allowance of magnesium, you could experience a range of symptoms.

Keep reading to discover everything you need to know about the symptoms of magnesium deficiency and how magnesium deficiency works.

How Magnesium Deficiency Works

If you aren’t getting your recommended daily amount of magnesium, then you might develop magnesium deficiency.

Magnesium deficiency is rare. However, millions of people worldwide still have a magnesium deficiency for various reasons.

Older adults and alcoholics are the highest-risk group for developing magnesium deficiency. However, some people are also deficient in magnesium due to health conditions or specific medication.

One study found just 2% of Americans are magnesium deficient. However, your chances of magnesium deficiency are much higher if you are in the hospital, have diabetes, or have alcoholism.

Symptoms of Magnesium Deficiency

If you don’t get enough magnesium in your diet, then you could develop symptoms like:

  • Nausea and vomiting
  • Fatigue and weakness
  • Loss of appetite
  • Nervous system dysfunction, including shaking, muscle spasms, and hyperactivity
  • Sleepiness
  • Abnormal heart rhythms
  • Pins and needles

Because magnesium plays a crucial role in regulating the nervous system, many of the obvious symptoms of magnesium deficiency include problems with your nervous system.

Some people also develop mental health conditions based on magnesium deficiency. One study found a connection between magnesium deficiency and depression, for example.

Health Problems Linked to Magnesium Deficiency

If you do not address magnesium deficiency over time, you could experience health problems like:

  • Heart disease
  • High blood pressure
  • Osteoporosis
  • Migraines
  • Causes of Magnesium Deficiency

Although magnesium deficiency is uncommon, many people have conditions that could cause magnesium deficiency.

Some of the most common causes of magnesium deficiency include:

  • Poor dietary habits
  • Type 2 diabetes
  • Digestive issues or absorption issues (like Crohn’s disease)
  • Kidney problems
  • Certain medications
  • Chronic vomiting or diarrhea
  • Alcoholism

Some people have all of the conditions above yet do not develop magnesium deficiency. However, certain people have a higher risk of magnesium deficiency. Older adults with a poor diet, for example, may be more likely to develop magnesium deficiency than younger adults with a poor diet.

How to Target Magnesium Deficiency

The best way to target magnesium deficiency is to adjust your diet or take a magnesium supplement. Talk to a doctor to find the optimal magnesium dosage for your unique needs.

In some severe cases of magnesium deficiency, doctors may recommend intravenous magnesium treatment.

Many people relieve symptoms of magnesium deficiency by adjusting their diet. Get more magnesium-rich foods, for example, to naturally relieve magnesium deficiency.

However, if you have an absorption issue (like Crohn’s disease or other digestive conditions), then a magnesium supplement and dietary changes may not be enough to solve your condition. Some people have a magnesium deficiency even though they’re getting their recommended daily intake of magnesium through dietary sources.

Best Food Sources of Magnesium

Some of the best food sources of magnesium include:

  • Leafy green vegetables (like kale)
  • Legumes
  • Nuts and seeds (particularly pumpkin seeds, almonds, and peanuts)
  • Whole grains
  • Popcorn
  • Dark chocolate

Some of the highest concentrations of magnesium in food by weight include flaxseed, sunflower seeds, chia seeds, cocoa, coffee, cashews, hazelnuts, and oats.

Recommended Dietary Allowance of Magnesium

Generally, adults need around 400mg of magnesium per day.

Your recommended dietary allowance of magnesium varies based on your age and gender.

According to the National Institutes of Health, here’s how much magnesium you should take:

Birth to 6 Months: 30mg for males and females

7 to 12 Months: 75mg for males and females

1 to 3 Years: 80mg for males and females

4 to 8 Years: 130mg for males and females

9 to 13 Years: 240mg for males and females

14 to 18 Years: 410mg for males and 360mg for females

19 to 30 Years: 400mg for males and 310mg for females

31 to 50 years: 420mg for males and 320mg for females

51+ Years: 420mg for males and 320mg for females

Meanwhile, pregnant females should take 350mg to 400mg of magnesium per day, and lactating females should take 310mg to 360mg of magnesium per day.

You can get an adequate amount of magnesium per day with multiple servings of 100g of peanuts (176mg of magnesium), 100g of popcorn (144mg of magnesium), or 100g of almonds (279mg of magnesium).

Vitamin D Deficiency: Symptoms & Solutions

Vitamin D is crucial for immunity, hormone production, and bone health, among other areas.

Many people, however, are deficient in vitamin D. They don’t get enough vitamin D through sunlight or dietary sources, leading to various symptoms.

Today, we’re highlighting some of the symptoms of vitamin D deficiency – and some of the best ways to solve vitamin D deficiency.

How Vitamin D Deficiency Works

Vitamin D is a crucial mineral for overall health and wellness. If you don’t get enough vitamin D daily, then you may develop vitamin D deficiency.

Vitamin D is unique because your skin produces vitamin D using sunlight. As sunlight hits your skin, it activates vitamin D production.

As you get older, your skin doesn’t convert sunlight into vitamin D as efficiently. People who have darker skin, and people over 50, are at a higher risk of vitamin D deficiency than younger people and those with fair-color skin.

Why Vitamin D is Important

As Cleveland Clinic explains, vitamin D is linked to crucial effects throughout your body – from strong bones and calcium absorption to effective hormone production, among other benefits.

Here are some of the reasons you need to get your daily intake of vitamin D:

Keep Bones Strong: Vitamin D is crucial for strong bones. If you don’t get enough vitamin D, particularly when young, then you may develop conditions like rickets, leading to soft and weak bones. Adults, meanwhile, may develop a similar condition called osteomalacia, or a softening of the bones. Your body also needs vitamin D to assist calcium and phosphorus, which have more of a direct role in bone development.

Help with Calcium Absorption: Even if you’re getting enough calcium per day, your body may struggle to absorb calcium because of low vitamin D levels. You need vitamin D to help absorb calcium. Calcium is important for more than just bones: it assists with everything from nerve function to digestive health.

Immunity: Vitamin D plays a crucial role in immune function by supporting your immune system in various ways. Studies show people with low levels of vitamin D tend to have weaker immune systems than people with sufficient levels of vitamin D. Other studies have connected vitamin D deficiency to an increased risk of serious infections.

Hormone Production: Many hormones are linked to vitamin D. Many men who are deficient in testosterone, for example, also tend to be deficient in vitamin D. Studies show getting adequate vitamin D is linked to balanced, normal hormone levels. That’s why many people notice mood changes when vitamin D deficient: vitamin D deficiency impacts hormones, and hormones play a crucial role in mood.

Health Conditions Linked to Vitamin D Deficiency

We know vitamin D supports a range of benefits in the body – from bone health to hormone production to immunity. However, lack of vitamin D could also contribute to serious health conditions.

Studies show people with vitamin D deficiency tend to have a higher risk of developing health conditions like:

  • Heart disease
  • High blood pressure
  • Diabetes
  • Infections
  • Immune system disorders
  • Balance issues, which could lead to falls in older adults
  • Certain types of cancer
  • Multiple sclerosis

Best Sources of Vitamin D

Fortunately, vitamin D deficiency is easy for most people to avoid. A small amount of sunlight per day, for example, can give you more than enough vitamin D. Or, some people take a vitamin D supplement or adjust their diet.

The best sources of vitamin D include:

Sun Exposure: Experts recommend getting 15 to 20 minutes of sun exposure 3 to 5 days per week for optimal vitamin D levels.

Food Sources: Some of the best food sources of vitamin D include fish like salmon, herring, sardines, canned tuna, and cod liver oil. Egg yolks and mushrooms are also rich with vitamin D. Alternatively, some foods and beverages are fortified with vitamin D for health benefits – like cow’s milk, soy milk, orange juice, cereal, and oatmeal.

Vitamin D Supplements: If sunlight exposure isn’t an option (say, at far northern latitudes or during the winter), then vitamin D supplements are an effective replacement.

Avoid Getting Too Much Vitamin D

Some people get too little vitamin D, while others get too much vitamin D. Yes, you can get too much vitamin D, which could lead to symptoms of its own.

If you get too much vitamin D, then you could develop vitamin D toxicity. The main issue with vitamin D toxicity is hypercalcemia, or a buildup of calcium in your blood.

Symptoms of hypercalcemia include:

  • Nausea and vomiting
  • Weakness
  • Frequent urination
  • Increased risk of calcium stones in the kidneys

If you notice any of the symptoms above, then reduce your vitamin D intake or see a doctor.

Most experts recommend a daily value (DV) of 800 IU of vitamin D per day. However, some argue for much higher doses of vitamin D. Recommended doses also vary based on age and gender.

Final Word: Take a Science Nutrition Lab Blood Test to Compare Vitamin D to an Optimal Range

8 Signs of Iodine Deficiency

Iodine deficiency is rare in industrialized nations. However, it’s becoming more common as people adopt unique dietary habits.

Vegans and vegetarians, for example, have an increased risk of iodine deficiency, as do pregnant women and people who don’t use iodized salt.

Iodine deficiency impairs your thyroid gland, which could lead to hormone issues, growth problems, cell damage, and a slow metabolism, among other noticeable symptoms.

Keep reading to discover the top 8 most common signs and symptoms of iodine deficiency and hypothyroidism.

Fatigue, Weakness, & Tiredness

Fatigue and weakness are two of the most common symptoms of iodine deficiency. They’re also two of the easiest symptoms to notice.

In one study, researchers found 4 out of 5 people with low thyroid hormone levels (thyroid hormones contain iodine) tended to feel sluggish and weak. In another study involving 2,456 people, researchers found the most common symptom across all patients were tiredness and weakness.

There’s a specific reason why iodine deficiency and thyroid problems are linked to energy issues: your body needs thyroid hormones to produce energy. Lower levels of thyroid hormones cause your energy to fall, making you feel tired and weak.

Unexpected Weight Gain

Some people with thyroid issues develop unexpected weight gain.

You might not have changed your diet and exercise habits, yet you’re gaining weight.

The reason? Iodine deficiency and thyroid problems slow your metabolism. Your metabolism dictates the rate at which your burn calories.

If you have started to gain weight, or if your diet and exercise routines seem to have little impact on weight management, then thyroid issues may be to blame.

Swelling in the Neck

One of the first noticeable signs of a thyroid problem is swelling in the neck, or a goiter.

A goiter is an inflamed thyroid gland. Sometimes, the goiter is so large that it becomes difficult to breathe and swallow.

You can develop goiters for several reasons – including low iodine and other issues. Talk to a doctor to determine what’s causing the swelling in your neck.

Hair Loss

Iodine deficiency is liked to hair loss. The iodine in your thyroid hormones helps to control the growth of hair follicles.

As thyroid hormone levels drop, your hair follicles stop regenerating. Over time, this leads to hair loss.

According to one study on 700 people, 30% of those with low thyroid issues developed hair loss.

There’s some debate over the connection between low iodine levels and hair loss. Although some studies have found a connection between the two conditions, others suggest the connection is linked to genetic reasons – not iodine deficiency or thyroid issues. Nevertheless, if you notice hair loss combined with other symptoms on this list, then it could be a thyroid / iodine issue.

Dry, Flaky Skin

Approximately 4 out of 5 people with hypothyroidism (caused by low iodine levels) have dry, flaky skin.

Your thyroid hormones are rich with iodine that helps your skin cells regenerate. If you have low thyroid hormone levels, your skin cells don’t regenerate as often as they should, leading to dry and flaky skin.

Iodine deficiency could also impact your ability to sweat normally. If you have low iodine and thyroid hormone levels, for example, then you tend to sweat less than people with normal thyroid hormone levels. This can lead to more dry, flaky skin issues.

Feeling Cold

Do you regularly feel cold when everyone else is a comfortable temperature? Do you frequently put on coats or extra layers? If so, you could have an iodine deficiency.

One study found 80% of people with hypothyroidism were more sensitive to colder temperatures.

Other studies have linked this issue to metabolism speed. Iodine deficiency causes your metabolism to slow down. A slower metabolism generates less heat than a faster metabolism, causing you to feel colder than usual.

Some studies have even connected thyroid hormone activity to brown fat. Brown fat is a special type of fat linked to heat generation. If you have low thyroid hormone levels, then your brown fat may be less active, leading to chronic coldness.

Slow Heart Rate or Changes in Heart Rate

Iodine impacts your heart rate. If you have low levels of iodine, then your heart could beat more slowly than normal.

Meanwhile, people with too much iodine could have a faster heartbeat than normal.

People with severe iodine deficiency tend to have very slow heart rates, which can lead to other noticeable symptoms of hypothyroidism – like mental fog, weakness, fatigue, and dizziness. Some people even faint because of their slow heart rate.

Mental Fog, Memory Issues, or Learning Problems

“Mental fog” is a symptom of hundreds of conditions. However, many people with iodine deficiency and hypothyroidism develop noticeable cognitive issues.

Studies show iodine deficiency can affect your ability to learn and remember. In this study, for example, researchers asked 1,000 adults to complete learning and memory tests. Researchers found adults who performed well on those tests had higher thyroid hormone levels than people with lower thyroid hormone levels.

5 Things You Need to Know About Iron Deficiency

Iron deficiency anemia is one of the most common mineral deficiencies in the world.

Fortunately, iron deficiency anemia is easy to spot, easy to test, and easy to target with various treatments.

Today, we’re explaining 5 things you need to know about iron deficiency anemia, including signs, symptoms, and causes of iron deficiency.

1) Symptoms of Iron Deficiency

People with iron deficiency anemia may have a range of minor to moderate symptoms.

Common symptoms of iron deficiency anemia include:

  • Fatigue
  • Cold hands, feet, fingers, and toes
  • Pale skin
  • Dizziness or lightheadedness
  • Mental fog

If you have a more serious case of iron deficiency anemia, then you may experience similar symptoms to general anemia, including excessive tiredness, shortness of breath, and chest pain.

Some people have no symptoms of iron deficiency anemia whatsoever. They feel fine, yet blood tests show they have chronically low levels of iron.

2) Causes of Iron Deficiency

The most common causes of iron deficiency anemia include blood loss and problems absorbing iron.

If you have a condition that causes excessive bleeding, for example, then you may have a higher risk of iron deficiency anemia.

The most common causes of iron deficiency anemia include:

  • Bleeding in your gastrointestinal tract (which can be caused by inflammatory bowel disease, colon cancer, celiac disease, ulcers, or intense athletic activity)
  • Heavy menstrual periods
  • Kidney disease (if you have kidney disease, then your body doesn’t make enough erythropoietin, a crucial compound in red blood cells)
  • Traumatic injuries or surgeries
  • Frequent use of NSAIDs (like ibuprofen) that could cause bleeding in your GI tract
  • Rare genetic conditions that make it hard to stop bleeding
  • Other conditions that block the absorption of iron

As we’ll explain below, some people also have iron deficiency because their bodies can’t absorb enough iron.

3) Why Iron Supplements May Not Be Enough: You May Have Trouble Absorbing Iron

Many people think they can solve iron deficiency anemia simply by taking an iron supplement or multivitamin. That’s not true.

In fact, many people with iron deficiency anemia get more than enough iron in their diet – yet they struggle to absorb iron for various reasons.

Some of the reasons you may have trouble absorbing iron include:

  • Rare genetic conditions that block your intestines from absorbing iron
  • Other genetic conditions that make it difficult to stop bleeding
  • Intestinal and digestive conditions like celiac disease, Crohn’s disease, or ulcerative colitis
  • Weight loss surgery
  • Other surgeries on your stomach and intestines
  • Internal bleeding that must be fixed with surgery

Some intense athletes also struggle to absorb iron. Endurance sports, for example, can cause athletes to lose iron through their digestive tract and via the breakdown of red blood cells.

4) Treatment for Iron Deficiency

A medical professional can build a custom treatment plan for your iron deficiency anemia.

By addressing the cause of blood loss or the issues with iron absorption, you may be able to prevent iron deficiency anemia by targeting the root of the condition.

Common ways to prevent iron deficiency anemia include:

  • Get more sources of iron in your diet, including beans, dried fruit, eggs, salmon, tofu, dark green leafy vegetables, or bread and grains fortified with iron
  • Eat vitamin-C rich foods, including fruits and vegetables, that help your body absorb iron
  • Take iron supplements
  • Take intravenous iron (it may only take a few sessions to address low iron levels)
  • Take medicine to promote red blood cell production (like erythropoiesis stimulating agents for kidney disease)
  • Get a blood transfusion

Obviously, these treatments range from basic at-home solutions to more medically-advanced treatments. By talking to a doctor, you can determine the right treatment for your iron deficiency.

5) When to See a Doctor

Doctors diagnose iron deficiency anemia using a blood test.

A blood test checks your complete blood count (CBC), hemoglobin, blood iron, and ferritin levels.

Doctors can also determine the root cause of your iron deficiency – like surgery or a genetic condition.

If you are concerned about your health and wellness, visit a doctor to determine if your symptoms are linked to iron deficiency.

Final Word: Take a Science Nutrition Lab Blood Test to Spot Iron Deficiency Before Symptoms Appear

A Science Nutrition Lab at-home blood test checks iron levels in a different way than a traditional blood test:

  1. You take a blood test at any local clinic in your area
  2. Results are shipped to our lab
  3. Results are compared to an optimal range based on your age and demographic data (not a random sample of people who recently used the lab, as is the case with ordinary blood tests)
  4. Jason Jumper reviews your results and determines the best way to target iron deficiency and other conditions, including supplements to take and lifestyle changes to implement

With a few simple steps, you can identify iron deficiency in your blood long before major symptoms appear.

10 Overhyped Superfoods That Aren’t Worth the Price

Not all superfoods are backed by science. Some superfoods are overhyped and overpriced.

Save your money and support your health by avoiding the superfoods below. They’re not as “super” as the internet has told you.

Cold-Pressed Juices

Cold-pressed juices are trendy and expensive. You can find them at health food stores and juice bars around the world. Some even make their own juice at home with high-end juicers.

Cold-pressed juices certainly aren’t bad for you. However, they’re not as good as many people think.

When you drink cold-pressed juice, you’re getting similar ingredients to regular juice: you get a lot of sugar and some vitamins and minerals, but not much more.

Most experts agree it’s better to eat the whole fruit, including the skin, flesh, and seeds of the fruit. It’s the way nature intended. When you eat fruit whole, it gives you fiber to fill you up and delay the absorption of sugar into your body.

Cold-pressed juices are trendy – but they’re not much better for you than ordinary fruit juices, and you’re probably better off taking whole fruits instead.

Acai Berry

Acai berry, like other overhyped superfoods on this list, isn’t necessarily bad for you – but it’s not as good as people think.

Acai berry is rich with antioxidants, vitamins, and minerals.

However, acai berry is not much more nutritionally relevant than berries you can easily buy at a local supermarket. It has similar antioxidant content to:

  • Strawberries
  • Blueberries
  • Raspberries
  • Cranberries

You can buy the berries above at a fraction of the cost – and enjoy similar benefits to acai berries.

Goji Berries

Goji berries occupy a similar space to acai berries: people throw around words like “antioxidants” and “nutrient-dense” when talking about goji berries.

However, there’s little evidence goji berries can reduce the risk of cancer, boost immunity, or improve cardiovascular health, among other benefits commonly advertised online.

In fact, many of the studies on goji berries come from studies on special goji extracts – not the berries themselves. These extracts are the equivalent to eating thousands of goji berries at once – and it’s not realistic to connect those benefits to adding a few goji berries to your smoothie each morning.

Coconut Water

People who drink coconut water love to talk about its hydrating properties.

Some people claim coconut water cures or prevents hangovers, for example. Others drink coconut water during or after a workout.

However, there’s little evidence suggesting coconut water has better hydrating properties than ordinary water.

Coconut water is also rich with sugar: each 8oz serving has 2 to 3 teaspoons of sugar and around 50 calories. If you’re looking to stay hydrated without the filler content, then water is a better choice than coconut water.


Have you ever taken a wheatgrass shot? You may have heard about the benefits of taking ingredients like chlorophyll. Someone might have told you about how wheatgrass is rich with vitamins A, C, and E along with minerals like iron, calcium, and magnesium.

Wheatgrass, like other so-called superfoods on this list, isn’t necessarily bad for you – but it’s not as good as people think.

The biggest problem with wheatgrass is that chlorophyll has no known nutritional value in humans.

Yes, wheatgrass is packed with vitamins and minerals – but so are multivitamin supplements and thousands of other fruits and vegetables.

Until science tells us there are specific benefits linked to the chlorophyll in wheatgrass, wheatgrass will continue to be an overhyped superfood deserving of its place on this list.


Search online for “best superfood drinks” and kombucha is sure to appear. Kombucha is a type of fermented black tea.

According to people online, kombucha is linked to benefits like:

  • Detoxification
  • Immune support
  • PMS relief
  • Energy
  • Digestion

That all sounds good. Unfortunately, however, there’s little concrete evidence linking kombucha to these claims.

In fact, most studies suggest ordinary teas like black or green tea – can provide superior benefits to fermented teas like kombucha. These teas are backed by thousands of studies – and centuries of use – linking them to heart health, immunity, and longevity.

Nevertheless, it’s not all bad news for kombucha drinkers: recent studies have found fermenting black and green tea can enhance its antioxidant properties. However, more human trials are needed to verify any of the benefits listed above.

It’s true kombucha, like other fermented foods, has probiotic bacteria. However, the levels of probiotics are smaller than you would get in yogurt, kefir, and other easy-to-find foods.

Certain Milk Alternatives

Milk alternatives are more popular today than ever before. Many people take nut or soy milk daily, for example, to enjoy non-animal sources of milk.

However, most milk alternatives are different than people realize. A typical nut or soy milk, for example, contains just 2% of the active ingredient. The rest of the beverage consists of water, vegetable oils, sweeteners, and additives. These additives enhance shelf life and flavor, but they do little for the nutritional value.

Consider making your own milk alternatives at home. You can enjoy all of the benefits of milk alternatives – with none of the additives or sweeteners.

Final Word

Don’t believe everything you read on the internet.

Some superfoods are backed by science, proven to work, and linked to genuine benefits.

Other superfoods are overhyped, overpriced, and overused.

6 Science-Backed Superfoods Available at Any Supermarket

People like to toss around the term “superfood”. However, there are plenty of genuine superfoods.

Some superfoods are rich with nutrients, fatty acids, fiber, vitamins, and minerals that can support health in various ways. They’re genuine superfoods backed by science to support health and wellness.

Other superfoods are overhyped. They’re not bad for you – but they don’t truly deserve to be called superfoods.

Here are some of our favorite science-backed superfoods available today – including superfoods available at any ordinary grocery store:


Food doesn’t need to be fancy and exotic to be a superfood. Eggs are a genuine superfood. They’re packed with:

  • High-quality protein to support muscle development and skin
  • Vitamin A, iron, phosphorous, selenium, B vitamins, and other vitamins and minerals
  • Antioxidants like zeaxanthin and lutein linked to eye health and vision
  • Choline to support cognition, memory formation, and overall brain health

Sure, eggs have high cholesterol content. However, studies show dietary cholesterol doesn’t impact your body’s cholesterol like previously thought. In this study, for example, researchers found people who ate 6 to 12 eggs per week did not have a higher risk of heart disease or diabetes.

In fact, one study found eggs increase HDL (“good”) cholesterol in some people.

For all of these reasons and more, eggs are a genuine, science-backed superfood.

Kale & Other Dark Green Leafy Vegetables (DGLVs)

Doctors often recommend getting more dark, leafy greens – and kale is one of the best dark, leafy greens you can take.

Kale, like other dark leafy greens, is rich with folate, zinc, iron, magnesium, calcium, fiber, and vitamin C.

Studies on dark green leafy vegetables (DGLVs) have linked their consumption to a reduced risk of illness and disease. In this study, for example, researchers found people with adequate intake of DGLVs like kale had lower levels of heart disease and diabetes.

Kale is also surprisingly rich with natural antioxidant chemicals – including carotenoids. Studies show diets rich with carotenoids may be associated with a reduced risk of cancer.

If you don’t like kale, then try other dark green leafy vegetables. Swiss chard, spinach, turnip greens, and collard greens all have similar benefits and nutrient content to kale.

Raspberries, Strawberries, Blueberries, and Other Berries

You don’t need exotic berries like acai to get your daily superfood intake; instead, some of the best superfood berries include common options like raspberries, strawberries, blueberries, blackberries, and cranberries.

All of these berries are rich with:

  • Vitamins
  • Minerals
  • Fiber
  • Natural antioxidants

Studies show people with high berry intake in their diet tend to have a lower risk of heart disease and cancer. Other studies have found people who eat berries have less inflammation. Inflammation is linked with stress, aging, and an increased risk of disease.

Meanwhile, this 2018 study published in Nutrition Reviews found berries had beneficial effects on the digestive system, which led to significant benefits for the immune system. 70% of your immune system is found in your gut. Berries support microbiota in your gut, making it easier for your immune system to function optimally.

All berries have slightly different levels of nutritional value; however, any of the berries listed above are considered genuine superfoods.

Green Tea

Tea is the world’s most popular antioxidant beverage – and green tea is one of the best types of tea available.

Green tea is rich with antioxidants, polyphenols, and natural chemicals with potent antioxidant effects. Numerous studies have linked green tea to benefits like weight loss, disease mitigation, and stress and anxiety relief, among others.

One of the superstar ingredients in green tea is epigallocatechin gallate (EGCG). This specific antioxidant compound is linked to a reduced risk of chronic disease, among other benefits – and it’s just one of several catechins in green tea.

In this 2018 study, researchers found EGCG lowered the risk of cardiovascular disease and diabetes. Meanwhile, this 2010 study published in Physiology & Behavior found green tea had significant effects on fat burning, fat oxidation, and weight loss.

If you’re looking for an easy, tasty, and science-backed superfood to add to your diet today, then green tea is one of the best options available.


People have prized garlic for centuries for its benefits. Today, we know more about how garlic works – and it’s clear garlic should be considered a superfood.

In this 2014 study published in the Indian Journal of Cancer, for example, researchers found garlic had potent effects on the cardiovascular system and immune system. Researchers found garlic reduced cholesterol and blood pressure while supporting immune function, for example. Since cardiovascular disease is the number one killer worldwide, garlic could help mitigate this risk.

Today, we know garlic gets its benefits from active compounds like allicin. Allicin is the principle bioactive compound found in garlic.

One of the largest therapeutic reviews of allicin was published in 2014.Researchers found allicin and other compounds in garlic could reduce the risk of cardiovascular disease and diabetes while exhibiting anti-tumor and anti-microbial effects. However, researchers did not fully understand why allicin worked in these days.

Whether you like the taste or like the benefits, garlic is a science-backed superfood that could support blood pressure, heart health, immunity, and more.


Avocado is one of the world’s best-known superfoods. In fact, some people claim avocados are so nutritious you could live exclusively off avocados.

That may or may not be true, but studies show avocados are rich with monounsaturated fats (MUFAs) like oleic acid – similar to olive oil. In this study, researchers found oleic acid supported healthy inflammation throughout the body.

Other studies have linked avocados to potential benefits like:

In addition to being rich with oleic acid, avocados are rich with fiber, vitamins, minerals, and healthy fats, making them one of the best superfoods you can buy in any grocery store.

Final Word

Some of the best superfoods are found in ordinary supermarkets – not in exotic online stores.

Adding berries, eggs, leafy green vegetables, green tea, and other science-backed superfoods to your diet can help in numerous ways.

Consider adding any of the superfoods above to your diet to support a range of science-backed benefits.

Top 7 Best Supplements for Mental Fog

Do you feel fuzzy, tired, or just “off”? It could be mental fog.

Millions of people deal with mental fog every day.

Fortunately, the right supplements can help. Some supplements support cognition and mental wellness. Others energize the brain, boost focus, or even enhance memory formation.

Keep reading to discover the top 7 best supplements for targeting mental fog and supporting your brain.

Caffeine, Coffee, and Green Tea

Caffeine, when used in moderation, is one of the best ingredients for mental fog. In fact, some see caffeine as the world’s most popular nootropic (brain boosting) ingredient.

Caffeine is a stimulant that interacts with pathways in your brain involved with focus, memory formation, and attention.

Drink a cup of green tea daily. Green tea contains ingredients like L-theanine that nullify the negative side effects of caffeine. L-theanine may also have its own brain boosting properties.

Coffee and tea are also rich with antioxidants to support your brain. Antioxidants neutralize free radicals in your brain, which could help clear up brain fog.

The combination of antioxidants, L-theanine, and caffeine could be a winning combination against your brain fog.

Of course, many people struggle with brain fog even with caffeine. For many people, a cup of coffee (or even a pot of coffee) has little impact on brain fog. In fact, some people experience worse brain fog with caffeine.

Antioxidant-Rich Fruits and Vegetables

We mentioned antioxidants above. However, antioxidant-rich fruits and vegetables could provide further defense against brain fog.

Fruits and vegetables are rich with natural antioxidants like anthocyanins that neutralize free radicals in your brain, helping with brain fog and mental wellness.

Vitamin C Supplements

Fruits and vegetables are also rich with vitamin C, one of nature’s best antioxidants. Vitamin C is known for its effects on immunity but it can also impact brain health.

In one 2019 study, researchers found people with higher levels of vitamin C in their blood tended to score better on memory, attention, response time, and concentration tests than people with low levels of vitamin C.

One of the best ways to raise vitamin C levels in the bloodstream is to eat more fruits and vegetables. Alternatively, you can take a multivitamin or a vitamin C supplement.

B Complex Supplements

Low B-vitamin levels are among the most common causes of mental fog.

B-complex vitamins are crucial for physical and cognitive energy. If you have chronically low energy levels, then you may not be getting enough B vitamins in your diet.

Some of the most common symptoms of B vitamin deficiency are also common symptoms of mental fog, including:

  • Memory issues
  • Difficulty concentrating
  • Lack of focus or poor cognition

Consider taking a vitamin B12 supplement to help with brain fog. In one study, researchers found a vitamin B12 supplement enhanced cognition in 84% of participants and improved memory and attention in 78% participants. The study involved 202 people with cognitive issues, mental fog, and low B-vitamin levels.

Vitamin D Supplements (or Sunshine)

Have you been outside in the sun lately? If not, you could be at a higher risk of experiencing mental fog.

Your body starts to produce vitamin D when sunlight touches your skin. Approximately 10 to 20 minutes of sunlight exposure is enough to get your recommended dietary allowance (RDA) of vitamin D.

However, due to climate, latitude, and seasons, you may be unable to get your daily recommended sunlight exposure. In this situation, you may want to take a vitamin D supplement. A vitamin D supplement can deliver an equivalent dose of vitamin D to support cognition and overall health and wellness.

Multiple studies have linked vitamin D to cognition and mental fog. In this 2020 study, for example, researchers connected vitamin D deficiency to depression. Other studies have linked vitamin D to mental fog and other cognitive issues.

Omega-3 Fatty Acid Supplements

Omega-3 fatty acids are well-recognized for their effects on brain health. Many experts recommend getting omega-3 fatty acids daily for brain health and cognition.

In one study, researchers took a group of 176 people with low levels of omega-3 fatty acids. These people took 1.16 grams of the omega-3 fatty acid DHA for six months. After six months, researchers observed significant improvements to episodic and working memory compared to a group that took a placebo.

Adding omega-3 fatty acids to your diet is easy: eat more fatty fish. Or, buy a fish oil or krill oil supplement. Omega-3 fatty acids are crucial for memory, cognition, and overall brain health.

Magnesium Supplements

If you don’t get enough magnesium in your diet, then you could experience mental fog.

Some of the symptoms of low magnesium include:

  • Brain fog
  • Difficulty concentrating
  • Worse responses to stress

The most common food sources of magnesium include green and leafy vegetables like spinach along with legumes, nuts, seeds, and whole grains.

Magnesium supplementation could be more important as you get older. In this study, researchers found a group of 2,466 adults over 60 performed better on cognitive function tests (including attention and memory tests) and had lower risk of cognitive impairment when they had higher magnesium levels compared to those with lower magnesium levels.

Other studies have connected magnesium to focus, attention, depression, and anxiety, among other cognitive conditions.

You can add more magnesium to your diet. Or, you can take a magnesium supplement.

Final Word

You don’t need to suffer with brain fog.

There are science-backed ways to target and relieve brain fog. The supplements listed above can support your body’s natural defense against brain fog, helping you support memory, cognition, focus, and more.

Take a Science Nutrition Lab at-home blood test today to discover your nutritional deficiencies – and discover the root cause of your brain fog.

Dietitian Versus Nutritionists: What’s the Difference?

Many people use “dietitian” and “nutritionist” interchangeably. However, they’re different professions.

Dietitians and nutritionists work in similar fields but have different backgrounds and certifications.

To help you get the best and most science-backed nutritional advice possible, here are some of the differences between dietitians and nutritionists.

Dietitians Must Be Certified by the Academy of Nutrition and Dietetics

In the United States, all dietitians must be certified by the Academy of Nutrition and Dietetics. Otherwise, they cannot practice as a dietitian.

Once certified, a dietitian can recommend specific foods to treat various health conditions.

The Academy of Nutrition and Dietetics certifies dietitians as Registered Dietitian Nutritionists, or RDNs. An RDN is qualified to provide medical nutrition therapy (MNT), which means they recommend specific foods to take to manage certain health conditions.

After receiving RDN certification, dietitians may provide medical nutrition therapy in a private practice (say, by opening their own clinic or working for someone else). Or, they could work in a hospital, school, nursing home, food company, or public health office.

Nutritionists May or May Not Be Certified

Some nutritionists are certified, while others are not.

Unlike dietitians, nutritionists do not have a single, all-encompassing certification board like the Academy of Nutrition and Dietetics.

Instead, some nutritionists are certified by the Board for Certification of Nutrition Specialists (BCNS).

Other nutritionists are certified clinical nutritionists (CCNs), which means they have been certified by the Clinical Nutrition Certification Board.

Some states require nutritionists to be certified by the BCNS, CCN, or other organizations.

However, other states require no certification for nutritionists whatsoever. Instead, it’s legal for anyone with any qualification not offer nutritional advice to another person, regardless of whether they have 20 years of experience or took a 20-minmute online course.

Nutritionists May Specialize in Certain Fields

To be clear, the Board for Certification of Nutrition Specialists is a legitimate and well-respected organization.

Nutritionists can specialize in different areas. They can learn how to use food to treat different disorders.

Some nutritionists specialize in areas like:

  • Sports nutrition
  • Digestive disorders
  • Autoimmune conditions
  • Keto dieting
  • Weight loss

Other nutritionists are generalists: they provide general information about using food for health and wellness, weight loss, and other areas, for example.

Registered Dietitian Nutritionist (RDN) Qualifications & Training

The Academy of Nutrition and Dietetics verifies dietitians have met certain qualifications before they can practice as Registered Dietitian Nutritionists.

To become an RDN and be certified by the Academy of Nutrition and Dietetics, you must meet the following qualifications:

  • Hold a bachelor’s degree or higher qualification from a regionally accredited university or college in the United States
  • Receive approval for coursework from the Accreditation Council for Education in Nutrition and Dietetics (ACEND) or the Academy of Nutrition and Dietetics
  • Complete 1,200 hours of supervised practice via an ACEND-accredited program
  • Complete an exam administered by the Commission on Dietetic Registration
  • Complete additional professional education requirements periodically to maintain registration

Nutritionist Qualifications & Training

Some nutritionists complete additional training, while others do not. Many nutritionists receive certification from the Clinical Nutrition Certification Board (to become a CCN) or the Board for Certification of Nutrition Specialists (to become a BCNS).

To begin training to become a CCN, the Clinical Nutrition Certification Board requires an individual to meet the following requirements:

  • Hold a Bachelor of Science (BS), Masters (MS), Doctor of Philosophy (PhD), or Doctor of Science (ScD) degree
  • Hold an advanced professional degree in another licensed healthcare field
  • If you meet these qualifications, then you must complete additional requirements to become a CCN. Specific requirements vary based on personal background and experience:
  • If you have a Bachelor of Science (BS) degree, then you must take a minimum of 3 course hours on topics like biochemistry, microbiology, and human physiology to become certified
  • If you have a more advanced degree, like a nursing degree or an ScD, then you can complete fewer training hours
  • Once training is complete, all CCNs must pass an exam
  • CCNs must complete ongoing training every 2 years to maintain their CCN designation

Once qualified, a CCN can provide personalized recommendations to clients for weight loss, exercise, supplements, and stress relief.

To become a Certified Nutrition Specialist (CNS), meanwhile, nutritionists need to meet the following qualifications:

  • Hold an MS or doctoral degree in nutrition or a related field
  • Complete coursework from a regionally accredited institution
  • Complete 1,000 hours of documented, supervised practice
  • Complete a BCNS accredited exam
  • Maintain certification with continuing education credits every 5 years

Once these qualifications are complete, the BCNS recognizes the individual as a Certified Nutrition Specialist (CNS).

Overall: Dietitians Versus Nutritionists

Dietitians and nutritionists both provide recommendations on using food to treat various diseases and illnesses.

However, the two professions have different qualifications.

Check your nutritionist or dietitian’s qualifications to ensure you’re receiving the best advice possible from a registered, certified, and experienced professional.

Top 6 Most Overrated and Overpriced Nutritional Supplements

Some people spend thousands of dollars per year on useless supplements.

They buy supplements backed by zero scientific evidence, for example. Or, they take supplements when they’re already getting enough of a specific ingredient in their diet.

Today, we’re highlighting the top 6 most overrated and overhyped nutritional supplements.

Testosterone Boosters

You can find testosterone boosting supplements at bodybuilding stores, big box retailers, and even pharmacies.

Unfortunately, there’s little evidence these supplements actually raise testosterone.

Instead, many of these testosterone boosters work by increasing blood flow or sex drive, making it feel like you have higher levels of testosterone.

Meanwhile, some of the less reputable testosterone boosters contain dangerous ingredients, stimulants, and artificial chemicals that have other, less desirable effects on your body.

Instead of taking a testosterone booster, the best way to increase testosterone is by:

  • Eating a balanced diet
  • Limiting stress
  • Exercising in moderation, including strength training

If you can do these three things, then you’ll increase testosterone more than any testosterone booster on the market.

Fat Burners

Want to lose weight without dieting or exercising? Fat burner supplements claim to be an easy and instant solution.

These fat burners all work in a similar way:

  1. Take one or two capsules per day
  2. Avoid dieting or exercising
  3. Lose significant weight in days or weeks

That’s it!

As you might expect, there’s little science behind most fat burner supplements. The best way to lose weight is by maintaining a healthy diet and exercise program – not by taking pills.

Fat burner supplements may contain some valuable ingredients – like caffeine, which is the world’s most popular fat burner. Studies show caffeine can induce thermogenesis, encouraging your body to burn fat.

Some fat burners also contain green tea, which is rich with an ingredient called epigallocatechin gallate (EGCG), an antioxidant linked to fat burning.

However, you don’t need an overpriced fat burner to get caffeine or green tea: just drink tea or coffee daily to enjoy similar fat burning benefits.

Metabolism Boosters

Some nutritional supplements claim to boost your metabolism.

These supplements are targeted to people who feel like they have a “slow metabolism.” You might struggle to lose weight, for example, because you have a slow metabolism.

It’s true: some people have a faster metabolism than others.

However, there’s no evidence that taking a dietary supplement can boost metabolism, increase your metabolic rate, or have a significant impact on the number of calories you burn per day.

Instead, the best and most proven way to boost metabolism is to exercise. Exercising increases the number of calories your body burns. Your body also continues to burn calories after the workout. If you want to maximize calorie burning, then exercise – don’t take a metabolism booster.

Nitric Oxide or Blood Flow Boosters

Many bodybuilders take nitric oxide boosters to raise blood flow before a workout.

These nitric oxide boosters claim to raise nitric oxide levels within your body, widening your blood vessels to improve blood flow. It gives you a better “pump” at the gym while boosting endurance.

Unfortunately, there’s little evidence that supplements can increase levels of nitric oxide in your blood.

Instead, many nitric oxide boosters contain stimulants like caffeine that trick you into thinking you have higher blood flow. You may feel better blood flow because of the stimulant, but it’s not because of higher nitric oxide levels in your body.

Instead, the best way to increase blood flow before a workout is to drink water before your workout. Staying hydrated will increase blood flow.

Garcinia Cambogia and Other Herbal Diet Pills

Garcinia cambogia has been one of the world’s most popular diet pill ingredients for the last decade. Unfortunately, there’s no evidence garcinia cambogia (and most other herbal diet pill ingredients) can help you lose weight.

The garcinia cambogia craze occurred after a single, small study linked garcinia cambogia to reduced appetite and better fat burning.

Today, supporters describe how garcinia cambogia is “rich” with natural fat burning ingredients like hydroxycitric acid (HCA). That may be true, but there’s no evidence that garcinia cambogia diet pills can block your appetite, activate fat burning, or make it easier to lose weight.

Instead, the best way to lose weight is to follow a healthy diet and exercise program. There are no herbal shortcuts to weight loss – no matter what garcinia cambogia supplement companies may try to tell you.

Collagen Supplements

Collagen is the most abundant protein in the human body, and it plays a crucial role in muscle development, joint health, and overall health and wellness.

Unfortunately, taking a collagen supplement won’t help you look 10 years younger overnight, nor will it eliminate all joint pain and wrinkles.

In fact, most collagen supplements are useless because our bodies already produce enough collagen. If you follow a healthy diet, then your body is already getting the collagen it needs. Taking a collagen supplement doesn’t change that.

However, collagen supplements may be useful if you’re deficient in collagen, have a low-protein diet, or have other dietary deficiencies. In this 2019 study published in Nutrients, for example, researchers found a collagen supplement improved skin hydration, elasticity, roughness, and density in a randomized, placebo-controlled, blind setting.

Final Word: Buy the Right Supplements

A good supplement supports your body’s deficiencies to support optimal health.

A bad supplement does virtually nothing.

Buy the right supplements today to ensure you’re getting the best value.

A single Science Nutrition Lab blood test identifies deficiencies, making it easy to take the right supplements.

Top 6 Best Science-Backed Supplements for Gut Health

Good gut health is linked to weight loss, immunity, energy, cognition, and other crucial processes.

If you don’t have good gut health, then your body struggles to absorb nutrients from the foods you eat.

Poor gut health could also lead to greater intestinal permeability and leaky gut.

Fortunately, some supplements are proven to support gut health, support the intestinal lining, and help with issues like bloating and indigestion.

Keep reading to discover the best supplements for gut health.


Probiotic supplements contain living bacteria colonies called colony forming units (CFUs). These CFUs encourage the growth and balance of bacteria within your gut. A healthy gut microbiome is crucial for gut health. Without a healthy balance of probiotic bacteria, your body struggles to break down the foods you eat, extract their nutritional value, and maintain intestinal permeability, among other issues.

Probiotics are some of the most-studied gut health supplements available today. According to the National Institutes of Health, probiotic supplements help your body maintain a healthy community of microorganisms, influence your body’s immune response, and produce substances with desirable effects, among other benefits.

Look for probiotics with multiple strains of bacteria and high levels of CFUs. To be considered a probiotic yogurt, yogurt must contain a minimum of 1 billion CFUs of probiotic bacteria, so your probiotic supplement should contain a similar number of CFUs.


95% of Americans don’t get their daily recommended intake of fiber. That’s unfortunate, because fiber is linked with everything from healthy blood pressure to better digestive health.

Fiber bulks up in your digestive tract, helping you push waste out of your body.

You can find plenty of “detox supplements” advertised online today with dramatic claims. However, many of these supplements simply contain high levels of fiber. That’s their secret.

As the Mayo Clinic explains, a high-fiber diet is linked to:

  • Normalized bowel movements
  • Maintenance of bowel health
  • Lower cholesterol levels
  • Better control of blood sugar levels
  • Weight loss
  • Longevity

The average man needs 38g of fiber per day (age 50 or younger) or 30g of fiber per day (age 51 or older).

The average woman needs 25g of fiber per day (age 50 or younger) or 21 grams of fiber per day (age 51 or older).

Psyllium supplements are affordable, easy to find, and plentiful, and you can easily take a psyllium supplement to get your daily recommended intake of fiber.


Used for centuries to help with stomach issues, ginger is popular in traditional Korean and Chinese medicine.

Today, studies show ginger is rich with natural ingredients with adaptogenic and antioxidant properties, which could make it valuable for gut health.

You can buy ginger supplements in powders, capsules, or tablets. Some people with digestive issues take ginger daily to help with nausea and vomiting. Others take it to soothe stomach aches.


Your body produces glutamine naturally, but many take glutamine supplements for added benefits. Today, a growing number of gut support supplements contain glutamine for that reason.

Studies show L-glutamine can help relieve diarrhea, especially if that diarrhea is linked to infections, stress, or a recent surgery.

One study connected L-glutamine supplementation specifically to gut microbiota. Researchers gave an L-glutamine supplement to a group of obese adults, then observed a significant improvement in gut bacteria levels.

Other studies suggest L-glutamine can help with nutrient absorption. If you have poor gut bacteria levels or are taking drugs that impair nutrient absorption, for example, then L-glutamine could support your body’s ability to absorb more nutrients.

Collagen Peptides

Collagen is the most abundant protein in the human body. Your body needs collagen protein for countless effects all over the body. That’s why many people take collagen peptide supplements daily.

Prized for their anti-aging effects, recovery benefits, and more, collagen peptide formulas can also help support gut health.

In one 2012 study, researchers found collagen peptide formulas had anti-inflammatory properties within the gut. Another study connected collagen peptides to leaky gut, finding collagen peptide supplementation helped prevent further breakdown of the intestinal lining.


Many are surprised to see licorice on a list of the best supplements for gut health. It’s true: certain types of licorice have been linked to gut health.

Using licorice for gut health isn’t new: it’s been used for centuries in traditional medicine to support gut health.

Today, you can take a deglycyrrhizinated licorice (DGL) supplement to give your body 75 bioactive compounds to support gut health in various ways.

One study linked licorice to lower inflammation and better mucus production in the gut. Another study found licorice works better when you remove glycyrrhizin (GL) because it has adverse effects in humans, although the other 75 bioactive compounds in licorice support health in other ways.

Take a Blood Test to Spot and Address Deficiencies

Nutritional deficiencies may be silently sapping your energy every day – and many don’t know it.

You may have nutritional deficiencies because of a poor diet. Or, you may have nutritional deficiencies because of poor gut health – even if you eat right, your gut may struggle to absorb nutrients.

Take a Science Nutrition Lab blood test to get the answers you need for your gut health.

Vitamin B12 Deficiency: Signs, Symptoms, and How It Works

Vitamin B12 deficiency is more common today than ever.

If you’re deficient in vitamin B12, you might experience low energy levels, numbness or tingling, weak muscles, or decreased appetite.

As vegan and vegetarian diets surge in popularity, millions of people are missing vitamin B12 – and many don’t know it.

However, people with Crohn’s disease, autoimmune disorders, or a history of gastric surgeries could all have vitamin B12 deficiency even if they get enough vitamin B12 daily.

Fortunately, vitamin B12 deficiency is easy to spot. Many people take a vitamin B12 supplement or multivitamin daily to manage the deficiency.

Today, we’re explaining everything you need to know about vitamin B12 deficiency, its symptoms, and how to address it.

What is Vitamin B12 Deficiency?

Vitamin B12 deficiency, also known as vitamin B12 deficiency anemia, is a condition where your body cannot produce enough healthy, red blood cells because it lacks vitamin B12.

Your body uses vitamin B12 to make red blood cells. If you aren’t getting vitamin B12 through dietary sources or a supplement, then your body cannot produce enough red blood cells.

Red blood cells play a crucial role in health and energy: your body uses red blood cells to transport oxygen throughout the body. When you have low red blood cell counts, your tissues and organs don’t get enough oxygen. You may feel lethargic, mentally foggy, or weak.

Symptoms of Vitamin B12 Deficiency

Symptoms of vitamin B12 deficiency anemia, according to the Johns Hopkins School of Medicine, include all of the following:

  • Weak muscles
  • Numbness or tingling in the hands and feet
  • Difficulty walking
  • Decreased appetite
  • Nausea
  • Weight loss
  • Irritability
  • Physical and mental fatigue or low energy
  • Smooth and tender tongue
  • Fast heart rate
  • Diarrhea

Who’s at Risk for Vitamin B12 Deficiency?

Certain groups and people have a higher risk of developing vitamin B12 deficiency than others.

Some of the risk factors for vitamin B12 deficiency include:

  • A family history of the disease
  • Removal of part or all of your stomach or intestine
  • Autoimmune diseases, including type 1 diabetes
  • Crohn’s disease
  • HIV
  • Certain medications
  • Strict vegetarian or vegan diets
  • Old age

Depending on your risk factors, doctors may develop a treatment plan for vitamin B12 deficiency based on your age, overall health, medical history, level of sickness, and ability to handle certain medications, among other factors.

Take a Blood Test to Spot Vitamin B12 Deficiency

Millions of people have lower-than-normal levels of vitamin B12.

If you believe you have vitamin B12 deficiency anemia, then a simple blood test can help.

A blood test checks your blood for vitamins and minerals, then compares levels to a normal range. If your vitamin B12 levels are significantly lower than normal, then you have vitamin B12 deficiency.

How to Address Vitamin B12 Deficiency

A doctor may help develop a custom treatment plan for vitamin B12 deficiency.

Some people can address the deficiency by taking a vitamin B12 supplement or a multivitamin.

Others simply adjust their diet, eating more foods rich in vitamin B12 than they previously did.

However, doctors may need to build a custom treatment plan based on your family history, medical status, and any medications you take. Sometimes, fixing vitamin B12 deficiency isn’t as easy as taking a vitamin B12 supplement.

Some of the ways to address vitamin B12 deficiency include:

Eat More Meat, Poultry, Seafood, Dairy Products, and Eggs: Vegetarians and vegans have a higher risk of vitamin B12 deficiency because there are few good plant-based sources. Consider adding more meat, poultry, seafood, dairy products, or eggs to your diet to increase vitamin B12 intake.

Take a Vitamin B12 Supplement: A vitamin B12 supplement contains 100% of your daily value (DV) of vitamin B12 or more, making it easy to get the vitamin B12 you need daily. You can buy dedicated vitamin B12 supplements or a multivitamin.

Take Plant-Based Foods Fortified with Vitamin B12: Some cereals and health foods are fortified with vitamin B12, making them a good source of vitamin B12.

Work with a Doctor to Create a Custom Treatment Plan: Adding more vitamin B12 to your diet is not guaranteed to fix vitamin B12 deficiency. Instead, you may need to work with a doctor to develop  accustom treatment plan for your deficiency.

5 Symptoms of Leaky Gut – and How to Get Help

Recent research has confirmed leaky gut is a real condition.

Millions of people suffer from leaky gut syndrome. When you have leaky gut, your intestinal wall is more permeable than normal, which means more toxins could leak through.

People with Crohn’s disease tend to have higher intestinal permeability, as do people with diabetes and autoimmune disorders.

However, leaky gut can affect anyone.

Today, we’re highlighting some of the most common sypmtoms of leaky gut – and things you can do to help support your gut.

What is Leaky Gut Syndrome?

Leaky gut syndrome is a gastrointestinal order affecting the permeability of your intestinal lining.

In a healthy gut, your intestinal lining is strong. It keeps foreign invaders out of your body, pushing them out of your body as waste.

If you have leaky gut, your intestinal wall isn’t as strong. It’s more permeable, which means more toxins could pass your intestinal barrier and enter your body.

Studies show people with leaky gut have tiny gaps that allow bacteria and other toxins to pass into the bloodstream. These tiny gaps are formed by tight junctions in the intestinal walls. The more tight junctions you have, the more permeable your gut may be.

Top 5 Most Common Symptoms of Leaky Gut

Common symptoms of leaky gut syndrome include:

  1. Digestive Issues (Chronic Diarrhea or Constipation): People with leaky gut syndrome often have issues making normal bowel movements. They might have chronic diarrhea or constipation, for example.
  2. Bloating or Gastrointestinal Discomfort: If you regularly feel bloated or have other gastrointestinal discomfort after eating a normal meal, then it may be a sign of leaky gut.
  3. Fatigue: Some people with physical fatigue have leaky gut. If you frequently feel like you have low energy, then it could be a sign of leaky gut.
  4. Mental Fog, Concentration Issues, or General Cognitive Concerns: If you have persistent mental fog, or if you’re struggling to concentrate, then it could be linked to leaky gut.
  5. Nutritional Deficiencies: Do you feel like you eat right – yet struggle with nutritional deficiencies? If a recent blood test has indicated multiple nutritional deficiencies, then it could be a sign of leaky gut.

Other Symptoms of Leaky Gut

Other, less common symptoms of leaky gut include:

  • Confusion
  • Skin problems, including acne, rashes, or eczema
  • Joint pain
  • Inflammation throughout the body
  • Depression and anxiety
  • Cravings for sugary or carb-heavy foods

The Problem with Diagnosing Leaky Gut Syndrome

Recent studies have proven leaky gut is a real thing. However, it’s difficult to diagnose the disease with 100% accuracy.

  • Many of the leaky gut syndrome symptoms above are shared with other conditions. You could have leaky gut – or you could have Crohn’s disease, irritable bowel syndrome, or other gastrointestinal diseases.
  • Complicating matters further is that certain members of the medical community do not recognize leaky gut syndrome as a real condition.
  • Some believe leaky gut syndrome is a cause or symptom of other diseases, like inflammatory bowel disease. It may not be its own syndrome, and it could simply be a cause or symptom of related diseases.

Despite these problems, millions of people have leaky gut and manage the condition daily. Effective management of leaky gut can support intestinal permeability, helping to restore your gut’s normal function.

Risk Factors for Leaky Gut Syndrome

Certain people have a higher risk of developing leaky gut.

People who consume higher-than-average amounts of alcohol, for example, have a higher risk of developing leaky gut, as do people with poor nutrition or autoimmune disorders.

Some of the risk factors for leaky gut syndrome, according to the Canadian Digestive Health Foundation, including:

  • Alcohol consumption
  • Poor nutrition
  • Autoimmune disorders
  • Infections
  • Diabetes
  • Stress

Yes, There’s a Test for Leaky Gut Syndrome

Research shows one test could identify leaky gut syndrome. Here’s how it works:

  1. A doctor tells you to take a liquid solution with mannitol and lactulose.
  2. Mannitol and lactulose are two water-soluble molecules your body cannot use.
  3. If you have a healthy intestinal lining, then your body will easily absorb mannitol. Mannitol is small enough to pass through your intestinal lining safely and be absorbed into the body.
  4. Your body absorbs less lactulose because it’s a larger molecule. A normal gut will only absorb some lactulose.
  5. Doctors check the absorption of mannitol and lactulose via a urine test. Doctors collect your urine for six hours after the test. They measure the amount of mannitol and lactulose excreted via urine.
  6. If you have a healthy gut, the test shows high levels of mannitol and low levels of lactulose.
  7. If you have a leaky gut, the test shows high levels of both mannitol and lactulose.
  8. If you have poor absorption of nutrients for other reasons, then the test may indicate low levels of both mannitol and lactulose.

How to Support a Leaky Gut

There’s still plenty to learn about leaky gut syndrome. However, studies suggest there are ways to support a leaky gut, support intestinal permeability, and support your body’s natural detoxification processes, including:

Avoid Processed Foods: Foods with high levels of sugar, refined oils, heavy processing, or high fat content are all bad for leaky gut and overall health. Studies appear to show a connection between processed foods and leaky gut, so it’s best to avoid these foods entirely.

Avoid Gluten: Some people have greater symptoms of leaky gut after eating foods with gluten. Try cutting gluten from your diet to see if you notice fewer symptoms of leaky gut.

Avoid Dairy: Dairy products could also increase symptoms of leaky gut syndrome. Try cutting dairy from your diet to see if you improve symptoms of leaky gut.

Avoid Alcohol: Alcohol increases intestinal inflammation, which is bad for leaky gut. Consider reducing or eliminating your alcohol intake to see if it helps your leaky gut.

Take a Probiotic Supplement: Probiotic supplements support colonies of gut bacteria in your intestines, and these colonies play a crucial role in gut health and breaking down the foods you eat. Consider taking a probiotic supplement to see if it helps your leaky gut. Or, eat fermented foods like yogurt, sauerkraut, kefir, and kimchi to support gut bacteria.

Final Word: Take a Blood Test to Check Nutritional Deficiencies

Leaky gut affects millions of people worldwide – and many of these people are unaware they have leaky gut syndrome.

Nutritional deficiencies are some of the first signs of leaky gut syndrome, and a single, painless blood test can easily spot deficiencies.

Consider taking a Science Nutrition Lab blood test today to check symptoms of leaky gut.

How to Test for Vitamin & Nutrient Deficiencies – and Why You Should

Vitamins are crucial for health.

By testing for vitamin deficiencies, you can spot problems before they become serious.

Thanks to modern science, it’s easier and more affordable than ever to test for vitamin and nutrient deficiencies. In fact, plenty of ordinary people test their blood regularly for vitamin and nutrient deficiencies.

How to Test for Vitamin & Nutrient Deficiencies

Modern medicine makes it easy to test for vitamin deficiencies.

From walk-in clinics to at-home tests, you have plenty of options for testing vitamin and nutrient deficiencies.

Some people order a full panel test, testing their blood for over a dozen vitamins and minerals.

Others target a specific vitamin to determine if they’re deficient. Some order a vitamin B12 test, for example.

There are two main types of blood tests to check for vitamin and nutrient deficiencies, including:

  • Venous blood tests, where a medical professional punctures a vein in your arm and collects a blood sample
  • A finger-prick blood test, where you prick your own finger and collect a small blood sample (say, with a home testing kit)

You can get a blood test through your physician. Alternatively, private companies offer blood tests for a range of issues.

Most Popular Types of Vitamin & Nutrient Deficiency Tests

Common types of blood tests include:

  • Comprehensive vitamin panels
  • Vitamin B12 tests
  • Vitamin D blood tests
  • Magnesium blood tests
  • Comprehensive mineral panels
  • Science Based Nutrition blood tests

Why Test? 5 Signs You Have a Vitamin Deficiency

You may be missing vitamins and minerals and not know it. In fact, your deficiencies could be affecting your health every day.

Here are 5 signs you may have a vitamin, mineral, or nutrient deficiency.

  1. You Notice Unexplained Hair Loss: You lose hair all the time. The average person loses around 100 strands of hair per day. However, sudden and unexplained hair loss could be the sign of a vitamin or mineral deficiency. Some people have low iron levels, for example, which could lead to severe hair loss. If you feel like you’re losing more hair than normal, then consider getting a vitamin or nutrient deficiency test.
  2. Your Wounds Take a Long Time to Heal: Your body heals wounds naturally. If your wounds are taking a long time to heal, however, then it could be the sign of a deficiency. People who bruise easily, for example, tend to have lower vitamin C levels.
  3. You Have an Irregular Heartbeat: A vitamin or nutrient deficiency could be the cause of an irregular heartbeat. Your body needs certain vitamins, including calcium, to keep its heart running smoothly. Calcium regulates your heartbeat. If you have chest pains, an irregular heartbeat, arrhythmia, or similar issues, then you may want to take a deficiency test (or visit a doctor immediately).
  4. You Have Mental Fog: Mental fog is a common condition. If mental fog is persistent, however, then it may be a sign of a vitamin or nutrient deficiency. If you’ve tried conventional treatments for mental fog (like getting enough sleep), then a vitamin or nutrient deficiency test may be the right choice.
  5. You Struggle to See at Night: Many people develop worse night vision as they get older. However, this may be a sign of a vitamin or nutrient deficiency. People with low levels of vitamin A, for example, may not be giving their retina the support it needs for good vision.

Other symptoms of vitamin and mineral deficiencies include:

  • Aching joints, muscles, and bones
  • A burning sensation in the feet or tongue
  • White growths on the eyes
  • Dry, itchy, or scaly patches of skin
  • Brittle hair and nails
  • Fatigue, nausea, and weakness

If you experience any of the symptoms above, you may want to take a vitamin and mineral deficiency test.

The Problem with Ordinary Blood Tests

You can order a specific type of blood test – say, for magnesium or vitamin D. However, a single Science Based Nutrition blood test can deliver even greater insight into your health.

Science Based Nutrition is a patented blood analysis system created by a Dayton, Ohio-based company. The goal was to create a better type of blood test.

While most blood tests use a Clinical Range to assess your health, a Science Based Nutrition blood test uses a superior testing system.

The Problem with Clinical Ranges: When you get an ordinary blood test, the lab checks your results against the last 100 to 200 people they tested. That means your bloodwork could be compared with anyone – including people who are sick. People who undergo lab testing typically have some type of health issue.

Your blood test may be “normal.” Unfortunately, because of clinical ranges “normal” doesn’t always mean “healthy.”

Science Based Nutrition solves that problem.

Science Based Nutrition is a Superior Type of Blood Test

To solve the problem of clinical ranges, Science Based Nutrition compares your blood work to an “Optimal Range” of people. This is a healthier population, and it can deliver greater insights into your health.

Instead of comparing your blood work to 200 random people who visited a lab, Science Based Nutrition considers your age, gender, and other personal information to determine optimal nutrient intake.

Optimal Range: Science Based Nutrition’s Optimal Range takes the middle 20% of the clinical range. You can discover potential health problems long before they appear on a traditional blood test.

Science Based Nutrition blood tests are affordable and easy. You can even do them at home.

What You’ll Learn on a Science Based Nutrition Blood Test

A Science Based Nutrition blood test delivers crucial insight into your health. Some of the things you’ll discover on your blood test report include:

  • A summary of any abnormal test findings (say, an abnormal red blood cell count)
  • The justification or data behind those findings (like low blood globulin levels detected on the test, for example)
  • How these tests connect to your symptoms (like cold hands, mental fog, or a high heart rate)
  • Recommended solutions for your vitamin and mineral deficiencies (say, taking a vitamin supplement or incorporating more leafy greens into your diet)
  • Other actionable information you can use today to solve your deficiencies, including specific supplement and dosage recommendations

Dr. Jason Jumper can explain these results during a remote consultation. Or, you can discuss test results with your own healthcare provider.
