Have you ever heard of biotin? It’s an important B vitamin that is found in foods.

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 mcg/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 swiss chard, tomatoes, romaine lettuce, and carrots. Other great sources include almonds, eggs, onions, cabbage, cucumber, and cauliflower. And good sources includes 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.

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.

Biotin deficiency is relatively rare and mild, and can be addressed with supplementation. Such deficiency can be caused by the excessive consumption of raw egg whites, which contain high levels of the protein avidin, which binds biotin strongly. Avidin is deactivated by cooking, while the biotin remains intact.

Biotinidase deficiency is not due to inadequate biotin, but rather to a deficiency in the enzymes that process it.

Signs of Biotin Deficiency: In general, appetite and growth are decreased. Dermatologic symptoms include dermatitis, alopecia (hair loss) and achromotrichia (absence or loss of pigment in the hair[6]). Perosis (a shortening and thickening of bones) is seen in the skeleton. Fatty Liver and Kidney Syndrome (FLKS) and liver problems also can occur.
