Biotin is necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids. It plays a role in the citric acid cycle, which is the process by which biochemical energy is generated during aerobic respiration. Biotin not only assists in various metabolic reactions, but also helps to transfer carbon dioxide. It may also be helpful in maintaining a steady blood sugar level. Biotin is often recommended as a dietary supplement for strengthening hair and nails, though scientific data supporting this usage are weak. As a consequence, biotin is found in many cosmetics and health products for the hair and skin.
Biotin is most often thought of as the “hair growth vitamin.” It is an essential water-soluble B vitamin. Biotin has come to be known for its role in the health and beauty of Hair, Skin and Nails. It promotes healthy hair growth and protects against dryness. It also increases the elasticity of the hair’s cortex, thus preventing breakage. However, biotin also has other uses. It is involved in carbon dioxide transfer and therefore essential to the metabolism of carbohydrate and fat. Biotin can be found in beans, breads, cauliflower, egg yolks, fish, kidney, legumes, liver, meat, dairy products, nuts, oatmeal, oysters, peanut butter, poultry, and whole grains.
