Biotin Deficiency

Biotin is a water-soluble vitamin, which is found in foods, like, tomatoes, carrots, chard, almonds, chicken, eggs, cabbage, strawberries, oats, walnuts, cow's milk, etc. Apart from foods, intestinal bacteria too produce biotin in good amounts. So, biotin deficiency is very rare, but, are commonly seen in alcoholics and people with medical conditions, like, achlorhydria, epilepsy, etc. Elderly people and athletes also have chances of developing biotin deficiency. Excessive consumption of raw egg whites (at least 20 eggs per day) can also cause biotin deficiency. Raw egg whites contain high amounts of protein called avidin, which binds with biotin, thus inhibiting its absorption. This protein in eggs is deactivated by cooking. Biotin deficiency can also be caused by genetic reasons and prolonged use of antibiotics.

Biotin deficiency is very rare, as it is required in very small amounts.
