The Truth About Biotin Deficiency

What is biotin?

Biotin, like all essential vitamins and minerals, has a plethora of effects on your body and is indispensable to your health. In your body, biotin acts as a coenzyme that helps you metabolize sugars, fats, and amino acids from the foods you eat. Biotin is involved in hair growth, skin and nail health, mood regulation, and immune system function.

In other words, you need biotin to turn the food you eat into fuel for your cells and building blocks to build and repair your tissues. For this reason and others, biotin affects your health and even your appearance.

What are the signs of biotin deficiency?

1. You have high blood sugar.

Biotin is critical in metabolizing sugar properly and maintaining healthy blood sugar levels 12. Without enough, you might be in trouble!

2. You have hair loss.

Deficiency in biotin can contribute to “uncombable hair” and baldness 34.

3. You have brittle nails.

Biotin is needed for the production of the strong keratin protein that gives nails their hardness and strength 5.

4. You have allergies.

Researchers have shown that the immune system can overreact to irritants if someone is deficient in biotin 6†.

5. You’re depressed.

Your brain is very hungry for biotin. The brain contains up to 50 times the amount of biotin that is in your blood 7. In medical literature, depression is cited as a potential symptom of biotin deficiency 89.

Biotin is involved in glucose and energy metabolism, and the neurons in your brain use glucose for energy 8.

6. You have skin rashes.

Biotin deficiency can cause skin problems because your immune system is not well regulated and inflammation is out of control 10.

7. You have poor heart health.

Biotin’s role in sugar metabolization affects your cardiovascular system. If you’re not using glucose efficiently, you’ll get high blood sugar levels, and this can damage the lining of your blood vessels so that you may develop high cholesterol 11. That sets you up for the development of plaque in your arteries.

8. You are pregnant.

Researchers say a “substantial proportion” of pregnant women are mildly deficient in biotin 12. Possibly as many as “18 out of 22” pregnant women are not getting enough biotin 12†!

9. You’re tired all the time.

As you know, biotin helps your cells use sugar for energy, and it is also necessary for the energy powerhouses of your cells, mitochondria, to work 1314.

Ways of Getting Enough Biotin

There are two ways of getting the biotin you need: (1) eating the right foods, and (2) supplementing.


If you need to supplement, it’s very safe. Biotin is a water-soluble vitamin, meaning that your body doesn’t store it in fat so it doesn’t carry the risk of overdosing like with some fat-soluble nutrients. Extensive research has shown that even very high doses of biotin is not toxic and does not cause noticeable symptoms 15. Only a tiny amount is needed to fulfill your needs. For adults, 25-100 mcg is often recommended.

Biotin-rich Foods

These foods are excellent sources of biotin:

  • Nuts
  • Seeds
  • Salmon
  • Avocado
  • Sweet potato
  • Cauliflower
  • Egg yolk
  • Mushrooms
  • Beans
  • Leafy greens

The Benefits of Biotin

1. It can lower “bad” cholesterol levels.

Research has shown that when people with high blood sugar supplemented with biotin and the mineral chromium, cardiovascular risk factors, such as triglycerides and “bad” cholesterol were lowered 15.

2. It might tone down your allergic reactions.

Research suggests that supplementation can improve allergies because biotin plays a role in moderating your immune function 16.

3. It can lower high blood sugar levels.

Research shows that biotin can reduce high blood sugar levels and can improve how your body handles fluctuations in blood sugar 1718.

4. It can improve nail appearance.

Biotin supplementation consistently improves the nail health of people with “brittle” nails 19.

5. You’ll have more energy.

If you’re a little low in biotin, getting more of this B-vitamin will give you an energy boost because your cells will use the calories you eat more efficiently.

6. You’ll grow hair better.

Studies have shown that biotin supplementation can boost hair growth in people who are battling baldness20.


1. Does biotin cause constipation?

There’s not much evidence for this in research, and there are only some anecdotal reports of biotin loosening stools.

2. Does biotin cause headaches?

Research shows that biotin, when included in a multivitamin, can reduce migraine pain and frequency21.

Many biotin supplements have very low amounts of biotin compared to the high levels used in experimental research. You’re unlikely to experience headaches when using biotin, but if you feel like you’re having them more often, stop taking your biotin supplement or take a very small dose (300 mcg).

3. Does biotin cause acne?

There is a concern that if you take too much biotin, it can cause a pantothenic acid (vitamin B5) deficiency that can then contribute to acne. If you want to avoid acne, take more conservative but adequate doses of biotin (300-600 mcg instead of higher doses like 10,000 mcg).

You may not think that your hair, skin and fingernails have much in common -- but they absolutely do. Brittle nails, limp, lackluster hair and sagging skin can all be tell-tale signs that your body needs a little...PEP.

The PEP Method, recently devised by scientists and researchers, has clinically demonstrated its effectiveness on parts of the body most affected by oxidative stress. Our skin being the largest organ in the body, it makes sense that signs of oxidative stress would show here first -- in the form of fine lines, wrinkles, dryness...tired skin that’s lost its youthful glow and “bounce”.

But the good news is, these signs can be reversed. Click here to learn more...
