Biotin is a B vitamin that plays a crucial role in converting food into energy and can also support skin, nail, and hair health. Biotin is found in foods like eggs, milk, bananas, whole grains, and nuts. Biotin deficiency can cause thinning of the hair and a rash on the face. However, biotin deficiencies are rare.
Here are some potential benefits and risks of biotin for skin:
Benefits:
- Biotin is necessary for the function of several enzymes known as carboxylases, which are part of important metabolic processes, such as the production of glucose and fatty acids.
- Although there is no good scientific evidence to support this use, biotin is commonly used for brittle nails, hair loss, and other conditions.
- When applied to the skin, biotin is likely safe for most people when used in cosmetic products that contain up to 0.6% biotin.
Risks:
- Biotin supplements might interfere with some lab tests, so it is important to talk with your doctor if you are taking biotin supplements and need to have any blood tests.
- There is insufficient data to support recommending biotin supplementation for hair, skin, and nail health.
- Supplements aren’t monitored by the FDA for safety, purity, dose, or quality, so it is important to research your brands before you buy.
Overall, while biotin is necessary for normal body function, there is limited evidence to support its use for skin health. It is always best to get nutrients from natural sources, and if you are considering taking biotin supplements, it is important to consult with your doctor first.
