Frequently Asked Questions About Biotin Supplements

What is Biotin?

Biotin is a water-soluble substance that is considered both a coenzyme and a B vitamin is known as vitamin B7. It contributes to the function of the metabolism, just as other B vitamins do, but is particularly important to the metabolism of carbohydrates and fats.

Biotin foods include several healthy foods such as wheat germ, whole wheat bread, eggs, peanuts, swiss chard, salmon, and chicken. Biotin deficiency can cause a host of health problems, such as hair loss, chronic fatigue, digestive issues, muscle aches, nerve damage, cramps, cognitive impairment, and more.

Biotin supplements can come in the form of a B complex vitamin, multivitamins, prenatals, or biotin alone. In a supplement, it may be called vitamin B7, vitamin H, biotina, biotine, or coenzyme R, but they are all the same thing.

The better products contain few fillers and are made by reliable manufacturers with quality biotin dosages. They can be taken as a tablet, effervescent, capsule, liquid, powder, and more.

What Are the Uses & Benefits of Biotin?

Biotin benefits your health in a number of ways, both inside and out. As a B vitamin, it plays an important role in the metabolic system. Most people know biotin for its ability to promote the health of your hair, skin, and nails.

Biotin can have a variety of uses and potential benefits in the body. Some of the most studied uses include:

  • Hair, Skin, and Nails: Vitamin B7 is an essential nutrient for the regular maintenance of skin, nails and hair. Thus, if a B7 deficiency is observed, the potential for issues such as thinning hair, dermatitis, etc. are more likely. Biotin has been used to address symptoms of skin rash, hair loss, and more. With that said, biotin deficiencies are rare and it’s unclear whether supplemental biotin will have any beneficial effect on those already eating a balanced diet.
  • Metabolism: Biotin, along with other B vitamins, is important for the metabolic function of the human body. B vitamins are used to help convert food into glucose, which your body uses as fuel. B7 does this by helping convert carbs into glucose, helping the body use proteins to carry out functions in the body, and activating fatty acids for use as energy.
  • Diabetes: When combined with chromium, biotin has been shown to improve insulin response, which can potentially help to balance blood sugar levels in people with diabetes. With that said, biotin should not be considered a standalone remedy for high blood sugar and should typically be used in combination with prescription medications and under the supervision of a doctor.
  • Brain Health: Biotin may also help to protect brain function and slow the progression of cognitive decline in old age. This effect is attributed to biotin’s role in neurotransmitter activity and nerve signaling. It is thought that B vitamins may help to slow the progression of various age-related neurodegenerative disorders like dementia and Alzheimer’s. B vitamins may also help to regulate the mood and increase concentration, although more research is needed to confirm these findings.
  • Cardiovascular Health: Various B vitamins may play a role in protecting the cardiovascular system against heart disease-causing conditions such as atherosclerosis, chronic inflammation, and stroke. In most studies these effects have been linked to B complex vitamins instead of standalone biotin – and it’s likely that the effects come primarily from folate and vitamin B6.

There are a lot of potential biotin benefits, but again it’s important to understand that a lot of these benefits will only apply if you are deficient in the vitamin. And in the Western world, most people get enough biotin from their diets.

Additionally, many of the studies looking at biotin used a combination of the vitamin alongside other nutrients or other B vitamins, which makes it difficult to identify the specific effects caused by biotin itself.

Who Can Benefit from Biotin?

  • Pregnant Women – Biotin is an important vitamin to the proper growth and development of a human fetus. This makes it a critical nutrient during pregnancy, which is why it is included in many prenatal vitamins.
  • Those with Thinning Hair or Brittle Nails – Biotin strengthens nails and may help to slow or reduce hair loss and thinning, especially in women with temporary hair thinning. It can help to strengthen hair by rebuilding shingles on the hair strands and thicken hair strands at the follicle. This results in fuller, healthier hair.
  • Those Taking Drugs that Lower Biotin Levels – Antibiotics, certain epilepsy medications, and lipoic acid can all reduce your levels of biotin and increase your dietary biotin needs. Biotin supplements can help to counteract these effects and support your overall health. Make sure to talk to your doctor before taking biotin in conjunction with any other medications.
  • Those at Risk of Biotin Deficiency – Your risk of biotin deficiency increases if you are a chronic smoker, an alcoholic, a pregnant woman, a person with liver or Crohn’s disease, or eating a diet with lots of processed foods. Taking biotin products can help to prevent a biotin deficiency and reduce the negative effects of some of these risk factors such as high cholesterol, high blood sugar, and the digestive effects of Crohn’s disease.

Are There Any Side Effects of biotin?

Biotin has been shown to be safe as a supplement, and researchers have not yet found an upper intake limit. There are no known side effects of biotin, but biotin may reduce the effectiveness of certain medications.

How Do I Take Biotin?

Since it is a water-soluble vitamin and can be taken at any time of the day, with or without food. There is no known upper limit to biotin, but a good biotin supplement generally will have a quality biotin dosage of between 1,000mcg to 10,000mcg.

Are There Any Beneficial Biotin Stacks?

  • Biotin and Chromium – Biotin stacked with chromium helps to enhance the cardiovascular health benefits of biotin. This biotin stack, in particular, has been shown to improve blood sugar.
  • Biotin and Calcium – Calcium and biotin are both very important nutrients to the normal growth and development of a fetus, and are both often included in prenatal vitamins. Calcium and biotin also work together to promote strong cardiovascular health, and to support hair growth.
  • Biotin and Omega-3 Fatty Acids – Biotin helps to rebuild shingles on hair strands to strengthen your hair, and thicken the follicles, which contribute to fuller, healthier hair. Omega-3 fatty acids help to promote luster, sheen, and growth of your hair. Together, these two nutrients help to support thick, full, shiny, and beautiful hair.
  • Biotin and Vitamin E – Biotin and vitamin E is a good biotin stack to enhance the skin health benefits of biotin. Vitamin E is an antioxidant and protects your skin from toxins and oxidative damage. This can help slow the effects of aging on skin health. Coupled with biotin, this is a great skin health formula.
  • Biotin and Silica Complex – Silica complex is a silicon mineral supplement that is often used for silicon deficiencies, which have become more common due to our modern diets. Silicon plays a vital role in the production of collagen, which is important to preserving youthful skin. Silica complex can also support cardiovascular health, joint health, and improve mineral absorption.
