Biotin (vitamin B8, sometimes called vitamin H) is a water-soluble B vitamin that plays a central role in carbohydrate, fat and protein metabolism. It’s a cofactor for several carboxylase enzymes involved in fatty acid synthesis and gluconeogenesis, and is particularly recognised for its role in the maintenance of normal hair and nails.
