Biotin is a water-soluble B vitamin typically found in liver, egg yolk, cereals, legumes and nuts. In the body, biotin is found in low concentrations in the brain, liver and muscle tissues. Biotin is essential for normal skin and hair growth, lipid metabolism and energy production (ATP). Alcohol consumption decreases biotin status in the body.

Who is likely to be deficient?

Certain rare inborn diseases can leave people with depletion of biotin due to the inability to metabolize the vitamin normally. A dietary deficiency of biotin, however, is quite uncommon, even in those consuming a diet low in this B vitamin. Nonetheless, if someone eats large quantities of raw egg whites, a biotin deficiency can develop, because a protein in the raw egg white inhibits the absorption of biotin. Cooked eggs do not present this problem.

Long-term antibiotic use can interfere with biotin production in the intestine and increase the risk of deficiency symptoms, such as dermatitis, depression, hair loss, anemia, and nausea. Long-term use of anti-seizure medications may also lead to biotin deficiency. Alcoholics and people with diseases of the stomach have been reported to show evidence of poor biotin status. However, the usefulness of biotin supplementation for these people remains unclear. In animals, and possibly in humans, biotin deficiency can cause birth defects. As biotin deficiency may occur in as many as 50% of pregnant women, it seems reasonable to use a prenatal multiple vitamin and mineral formula that contains biotin.

How much is usually taken?

The ideal intake of biotin is unknown. However, the amount of biotin found in most diets, combined with intestinal production, appears to be adequate for preventing deficiency symptoms. Researchers have estimated that 30 mcg per day appears to be an adequate intake for adults. Typically, consumption from a Western diet has been estimated to be 30–70 mcg per day. Larger amounts of biotin (8–16 mg per day) may be supportive for people with diabetes by lowering blood glucose levels and by preventing diabetic neuropathy. Biotin in the amount of 2.5 mg per day strengthened the fingernails of two-thirds of a group of people with brittle nails, according to one clinical trial.
