Biotin, also known as vitamin B7, is important for breaking down fats, carbs, and proteins in our food. You might have heard about biotin supplements if you’ve looked into ways to strengthen your nails or thicken your hair. Even though there’s not much evidence that biotin helps people without a deficiency, it can be helpful if you are low on this vitamin.

What is Biotin and Why Do You Need It?

Biotin is a B-vitamin found in foods like meat, fish, eggs, milk, seeds, nuts, sweet potatoes, spinach, broccoli, and bananas. It helps convert food into energy and supports healthy skin, hair, and nails. Most people get enough biotin from their diet. However, pregnant women, people with alcohol dependence, smokers, and those receiving kidney dialysis may need more biotin.

Who Should Take a Biotin Supplement?

You usually don’t need a biotin supplement unless you’re deficient. Signs of deficiency include thinning hair, brittle nails, and a red, scaly rash on the face. Biotin supplements can also help those on prolonged IV feedings, infants on formula without biotin, and people who eat a lot of raw egg whites, which contain a compound that prevents biotin absorption.

Possible Side Effects of Biotin Supplements

Biotin can interfere with lab tests, causing false readings. It can lower thyroid-stimulating hormone (TSH) levels, making it hard to diagnose thyroid problems. It can also affect tests for heart conditions, hepatitis, HIV, and COVID-19 antibodies.

How to Choose a Biotin Supplement

Look for biotin supplements with certifications like U.S. Pharmacopeia (USP), Good Manufacturing Practice (GMP), or NSF International. Avoid high-dose supplements unless needed.


Biotin supplements can be helpful for those with a deficiency, but most people get enough from their diet. If you’re considering biotin for hair, skin, or nails, try adding biotin-rich foods to your meals first. Always consult a healthcare professional before starting any supplement.
