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. Biotin is also helpful in maintaining a steady blood sugar level. Biotin is often recommended for strengthening hair and nails. Consequently, it is found in many cosmetic and health products for the hair and skin.
Deficiency is extremely rare, as intestinal bacteria generally produce an excess of the body's daily requirement. For that reason, statutory agencies in many countries (e.g., the Australian Department of Health and Aging) do not prescribe a recommended daily intake.
Biotin is widely distributed in a variety of foods, but most often at low concentrations. Estimates are that the typical U.S. diet provides roughly 40 ug/day. There are only a couple of foods which contain biotin in large amounts, including royal jelly and brewer's yeast. The best natural sources of biotin in human nutrition are liver, legume, soybeans, swiss chard, tomatoes, romaine lettuce, and carrots. This includes almonds, eggs, onions, cabbage, cucumber, cauliflower, goat's milk, cow's milk, raspberries, strawberries, halibut, oats, and walnuts. The most important natural sources in feeding nonruminant animals are oilseed meals, alfalfa, and dried yeasts. It is important to note that the biotin content of food varies and can be influenced by factors such as plant variety, season, and yield (endosperm-to-pericarp ratio).
Adequate intake are determined for nutrients when there is insufficient scientific evidence to establish a Recommended Dietary Allowance (RDA). These values are set as goals for individuals to support adequate nutritional status. NOTE: U.S. Food and supplement labels show 30 ug of biotin as providing only 10% DV (Daily Value) because DVs are based on older and in some instances outdated RDAs for nutrients. Thus, the DV for biotin is 300 ug even though there is now consensus that 30 ug is adequate. There is no current Tolerable Upper Limit (UL) set for biotin as research has indicated that high levels of intake by humans has no detrimental effects.
Biotin supplements are often recommended as a natural product to counteract the problem of hair loss in both children and adults. The signs and symptoms of biotin deficiency include hair loss which progresses in severity to include loss of eye lashes and eye brows in severely deficient subjects. Some shampoos are available that contain biotin, but it is doubtful whether they would have any useful effect, as biotin is not absorbed well through the skin.
Cradle cap (seborrheic dermatitis)
Children with a rare inherited metabolic disorder called phenylketonuria (PKU; in which one is unable to break down the amino acid phenylalanine) often develop skin conditions such as eczema and seborrheic dermatitis in areas of the body other than the scalp. The scaly skin changes that occur in people with PKU may be related to poor ability to use biotin. Increasing dietary biotin has been known to improve seborrheic dermatitis in these cases.
People with type 2 diabetes often have low levels of biotin. Biotin may be involved in the synthesis and release of insulin. Preliminary studies in both animals and people suggest that biotin may help improve blood glucose control in those with diabetes, particularly type 2 diabetes. Specifically, biotin doses in excess of nutritional requirements lower postprandial glucose and improve glucose tolerance.
