What Is Biotin?

Biotin is a B vitamin that is vital for facilitating healthy metabolism and creating crucial enzymes (2). As per expert opinion, biotin converts certain nutrients into energy and is believed to boost keratin synthesis and improve the keratin infrastructure of your body. Like any other vitamin of the B family, biotin helps the body metabolize proteins and process glucose. It is also known as vitamin B7 or vitamin H.

Since the human body cannot synthesize biotin, we need to consume it through our diet or supplements. The body does not build up any biotin reserves, and the unused biotin is flushed out of the body in urine. Therefore, it must enter our system daily through our diet. Biotin is a coenzyme that enhances an enzyme’s action.

Importance Of Biotin

Mammals cannot synthesize biotin. Hence, we need to depend on dietary intake from microbial and plant sources. Biotin works as a coenzyme for five carboxylases in humans. It helps the body process glucose and metabolizes proteins, fats, and carbohydrates. It shows excellent real-life results and is believed to be good for healthy hair, nails, and skin.

This vitamin is present in many health and cosmetic products, though biotin cannot be absorbed through the skin or hair.

The European Food Safety Authority (EFSA), which provides scientific advice to assist policymakers, has confirmed numerous benefits of dietary intake of biotin(3):

  • Essential for the metabolism of carbohydrate and fat
  • Aids energy-producing metabolism
  • Helps in the maintenance of healthy skin and mucous membranes
  • Aids the normal function of the nervous system
  • Helps in the maintenance of healthy hair
  • Aids normal psychological functions

Biotin supplements are gaining a lot of popularity and are readily available in the aisles of supermarkets. Here are the top 10 biotin supplements you can consider buying.

Biotin is an essential nutrient that is naturally present in small amounts in some foods and can also be taken as a dietary supplement. Since this vitamin is water-soluble, it is not stored in the body. Hence, you need to consume it through foods and supplements.

Unfortunately, there is no good laboratory test for detecting biotin deficiency. Low levels of biotin are reflected in symptoms like thinning of hair, brittle nails, and lackluster skin. Though deficiency is a rare phenomenon, it can occur in chronic smokers, alcoholics, and pregnant women (4), (5). Your diet can also trigger it. People who consume a lot of processed food are most likely to have a deficiency.

Here’s a list of few possible benefits of biotin:

  • May regulate blood sugar levels (6).
  • Assists in energy production (7).
  • Biotin is effective for treating brittle nails (1).
  • Biotin is said to promote healthy hair growth, though there is little evidence to support this claim (1).
  • Important during pregnancy and breastfeeding (8).
  • Improves your skin health. Biotin deficiency can lead to a variety of skin problems (9).

Buying a supplement should always be a well-researched decision. It is essential to focus on specific variables while shopping for a biotin supplement. Here’s a list of few factors that you need to keep in mind while buying a biotin supplement.

Buying Guide

  • Ingredients: It is the sign of an aware buyer to look up ingredients while making a purchase, especially when it comes to health-related products. If you are a vegan or vegetarian, ensure that the supplement does not contain animal-based gelatin. It is always better to go for non-GMO verified products and those that do not contain any common allergens.
  • Side Effects: Taking biotin supplements may lower your B5 levels, and this can lead to rashes, acne, and itchiness. Though this does not happen to everyone taking biotin supplements, in case you encounter this problem, talk to your doctor and start taking vitamin B5 pills alongside to balance things out. Also, if you are planning to get your blood tests done, you may have to lay off your supplements a day or two before. This is because biotin supplement messes with your blood test results. Talk to your healthcare specialist before taking any supplements.
  • Quantity: When on supplements, it is best to keep a check for pill count of each bottle and how much of the supplement each pill will supply. It is essential to ensure that you choose a supplement that has an adequate amount of biotin for your needs. If you are not sure, consult an expert or opt for the dermatologist-recommended supplements.

The Bottom Line

Biotin is a significant vitamin to keep your nails and hair healthy. However, a deficiency of biotin may cause many skin issues and even hair loss. So it would be best to concentrate on biotin supplements and take them regularly if your diet can’t provide enough biotin. But make sure that the biotin supplements promote healthy skin and hair. For a comprehensive hair, skin, and nail support, choose the Sports Research Biotin With Organic Coconut Oil, the Nature’s Bounty Biotin Supplement to offer essential nutrients for enhanced beauty from within., or the Solgar Super High Potency Biotin for a targeted and strong support for hair and nail health. However, if you are vegan or vegetarian, ensure that the supplement has no animal-based gelatin. But consult a doctor if the skin and hair issues are persistent.

Frequently Asked Questions

What should I know before taking a biotin supplement?

Most biotin supplements are available in megadoses that are generally more than the accepted amount that your body needs per day. Since it is a water-soluble vitamin, whatever is not absorbed and required by your body will be flushed out in the urine. Biotin supplements may interfere with the results of lab tests that test the blood (10).
If you are planning on taking biotin supplements, it is always recommended to consult your doctor before that to determine the appropriate dosage and the supplement you should opt for so that there are no potential threats to your health in the future.

How much biotin is too much?

As per the current nutritional recommendations, you should not exceed 10,000 mcg of supplemental biotin per day.
A few medical studies have reported using 40,000 mcg of biotin supplements to treat deficiencies, which did not exhibit any side effects, but if we talk about nutritional recommendations, 10,000 mcg or 10mg is the upper limit (1).

How much biotin is required for hair growth?

The FDA does not have a Recommended Daily Allowance (RDA) for biotin. Health experts recommend that if someone is above 10 years of age, they should get somewhere between 30 to 35 mcg of biotin per day (2). If you intend to speed up things, there is no harm in going up to 1,000 to 5,000 mcg. Consult a doctor, who will prescribe the right supplement and dosage for you.

What causes biotin deficiency?

Biotin deficiency is rare. It can be caused by one of the two factors – genetic mutation or excess of raw egg white intake. Egg white contains a compound that significantly inhibits biotin absorption, which is deactivated by cooking the egg.

Does biotin make you gain weight?

No, there is no scientific evidence to claim biotin supplements can make you gain weight. In contrast, since biotin supplements help speed up metabolism, they are occasionally promoted as a weight-loss product.

How long does it take for biotin supplements to start working?

It will take upto 6 months for biotin supplements to start working.
