Vitamin B7: Biotin

Biotin is water soluble and generally classified as a B-complex vitamin. After the initial discovery of biotin, nearly 40 years of research was required to establish it as a vitamin fraction and categorize it within the B-vitamins section. Studies have shown biotin may help create healthy hair and prevent brittle nails, and is required to properly metabolize fats and amino acids. Its most healthy forms can be found in sprouted grains, adzuki sprouts, and whole-grain rice.
