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 is rare and low levels may result in brittle nails and hair loss, explains Dr. Stuart. However, hair loss and brittle nails may have multiple causes and taking biotin supplements may actually halt this process and even help to reverse it. The general daily recommended dosage of biotin is 2.5 mg (or 2,500 mcg), according to Dr. Scher. However, it's not clear what the correct dosage is for the full effect, but it's important to consult your doctor to avoid overdosing.
