Overview
Biotin is necessary for cell growth, production of fatty acids and the metabolism of fats and amino acids. It plays a role in the Krebs cycle, which is the biochemical process by which energy is produced during aerobic respiration. Biotin not only participates in various metabolic reactions, but also helps to transfer carbon dioxide. Biotin is also helpful in maintaining a constant level of sugar in the blood. Biotin is often recommended for strengthening hair and nails. Accordingly, it is a component of many cosmetic and health products for hair and skin.
Biotin deficiency is extremely rare, as intestinal bacteria generally produce more than the body needs daily. For this reason, statutory agencies in many countries (for example, the Australian Department of Health and Aging - Australian Department of Health and Aging) do not prescribe recommended daily intake.
