Best Biotin Supplement: How to Choose

If you’re on a quest for long, luscious hair, strong, healthy nails and glowing, nourished skin, supplements containing biotin may help you achieve your ultimate health and beauty goals.

“Biotin, also called vitamin B7, is a water-soluble vitamin that plays a crucial role in carbohydrate, fat, and protein metabolism,” says Dr. Yoram Harth, a board-certified dermatologist and medical director of MDacne. “Due to its water-soluble nature, supplementation is considered very safe.”

We’ve rounded up some of the best biotin supplements and products on the market to help make your buying decisions easier. But first—let’s dive a little deeper and learn about biotin’s many benefits.

What is Biotin Good For?

When most people think about biotin, they associate it with healthy hair, skin, and nails. In fact, according to Dr. Alissia Zenhausern, a naturopathic doctor who runs NMD Wellness of Scottsdale, biotin used to be called vitamin H. “The H stood for Haar und Haur,” she says, “which is German for hair and skin.”

Biotin is found naturally in certain foods such as beef liver, boiled eggs, and pink salmon, says Harth. It’s also found in lower quantities in soybeans, peanuts, leafy greens, cauliflower, mushrooms, nuts, and nut butters.

“Adequate biotin levels are necessary for a number of critical functions in the body, including converting food into energy,” says Dr. Yelena Deshko, a naturopathic doctor and founder of Timeless Health Clinic. “While true biotin deficiency is rare, some people do have higher biotin requirements. These include pregnant and breastfeeding women as well as those that take certain medications such as anti-seizure drugs.”

While biotin is widely known as the “beauty vitamin,” research about its efficacy to promote hair growth and improve skin in healthy individuals (those not suffering from a biotin deficiency) is limited.

“Biotin deficiency has been linked to hair loss, therefore it is commonly included in various hair-growth-promoting supplements,” Deshko says.“While more research is needed, several preliminary studies have also shown biotin supplementation to improve nail strength and thickness (1).”

Biotin Supplement Benefits

In addition to assisting with nail growth and potentially promoting skin and hair health, biotin supplements are beneficial to pregnant women and breastfeeding mothers (2). In fact, studies have shown that pregnant women are likely to develop a mild biotin deficiency during pregnancy (3).

Biotin is also linked to other benefits, including controlling blood sugar in patients with Type 2 diabetes and in easing multiple sclerosis symptoms.

Supplementing with biotin is considered safe, due to its water-soluble nature. “The body does not store this vitamin, which makes overdosing on it much harder,” says Zenhausern. “If your biotin levels are too high, you can stop taking biotin and your body will naturally get rid of the excess biotin.”

How to Choose a Biotin Supplement

Biotin can be found in a variety of over-the-counter supplement forms.

“Most commonly it is found in capsule form. However, it is also available in liquid, powder, and even chewable gummy forms,” says Deshko. “It can be found on its own as a standalone supplement or included in a formula with other vitamins, such as in a multivitamin, prenatal vitamin, Hair Skin & Nails formula, or others.”

Recommended daily intake of biotin for adults is considered 30 micrograms (mcg)  by the Food and Nutrition Board (FNB) at the National Academies of Sciences, Engineering, and Medicine (4). But some people may benefit from higher doses, and overdosing on biotin is unlikely.

“Certain population groups such as individuals with chronic alcohol exposure, people taking certain epilepsy drugs, as well as pregnant and breastfeeding women may be more at risk of developing biotin deficiency and may require a higher daily intake,” says Deshko.

Although taking biotin supplements is generally considered safe, consult with your doctor prior to starting on a supplement regimen to go over dosing instructions and recommended brands.

“All supplement companies are NOT created equally,” says Zenhausern. “Make sure the brand you select is third-party tested for quality and purity standards.”

Where Can I Buy Biotin Supplements?

Biotin supplements are available at a variety of health and wellness retailers—both in stores and online.

Before purchasing from a company, conduct research to make sure the retailer is highly reviewed and recommended as a source for quality products. Your doctor may also be able to provide a recommendation for where to buy biotin supplements.
