Biotin is a vitamin found in foods like eggs, milk, and bananas. It is an essential nutrient that helps the body break down fats, carbohydrates, and proteins into energy. Biotin deficiency can cause thinning of the hair and a rash on the face. Biotin supplements are available in dietary supplements containing biotin only, in supplements containing combinations of B-complex vitamins, and in some multivitamin/mineral products. The absorption rate of oral, free biotin is 100%, even when people consume pharmacologic doses of up to 20 mg/day biotin.
