What it is

Vitamin B-7, also known as biotin, is a water-soluble vitamin that plays a role in metabolism. It is found naturally in foods like eggs, nuts, and whole grains. It can also be produced synthetically for use as a food additive.

Why it's used

Manufacturers add vitamin B-7 to foods as a nutrient supplement, particularly in energy drinks and fortified cereals. It is also sometimes included in dietary supplements aimed at supporting hair, skin, and nail health.

Health notes

Vitamin B-7 is generally recognized as safe (GRAS) by the FDA when used as a nutrient. The National Academies have established an upper intake level for biotin. JECFA and EFSA have evaluated biotin. While biotin is essential for health, very high supplemental doses have been shown to interfere with certain lab tests, leading to potentially inaccurate results.

Allergen info

Not a major allergen. Biotin is not derived from any of the nine FDA major allergens, nor does it contain gluten.
