1.    It plays a role in the citric acid cycle that is the process by which biochemical energy is generated during aerobic respiration.
2.    Biotin, besides to assist in various metabolic reactions, it also helps to transfer carbon dioxide.
3.    It is helpful again in maintaining a steady blood sugar level.
4.    Vitamin B8 is often recommended as a dietary supplement for strengthening hair and nails, thus biotin is found in many cosmetics and health products for hair and skin.
