Biotin is involved in the metabolism of protein, fats and carbohydrates. One clinical study showed that 2.5 mg of biotin per day strengthened the fingernails of two-thirds of people with brittle nails. Although it seems to help with cradle cap in infants, the whole B complex is of more value in adult seborrheic dermatitis than biotin alone. Biotin is produced by intestinal bacteria, so a biotin deficiency is rare. However, people using antibiotics on a long-term basis or who eat large amounts of raw egg whites can develop a deficiency, because the protein in raw egg whites inhibits biotin absorption.

  • Biotin is a member of the B vitamin family that functions in the manufacture and utilization of fats and amino acids.
  • Biotin deficiency is characterized by dry, scaly skin and seborrhea.
  • Biotin supplementation has been shown to increase the strength of nails and promote healthy hair.*
