Most adults need about 30mcg of biotin per day to maintain normal metabolic functions, which translates into healthy nails, skin and hair. Experts usually recommend a starting dose of about 700mcg of biotin per day and sometimes as high as 1000mcg.
Biotin deficiency can, however, be caused by a genetic disorder of biotin deficiency, surgical removal of the stomach, or seborrheic dermatitis in infants. In these cases, hair loss has been observed, leading to the rumor that biotin can grow or regrow hair. While there is no recommended dietary allowance, normal daily recommended biotin intakes range from 30 to 100 micrograms for both adolescents and adults, as stated by the Mayo Clinic.
