Experts usually recommend a starting dose of about 700mcg of biotin per day and sometimes as high as 1000mcg. Because it is generally safe and well-tolerated many people take as high as 10000mcg a day with no documented side effects.

Oral biotin supplementation has been well tolerated in doses up to 200 mg/day (nearly 7,000 times the AI) in people with hereditary disorders of biotin metabolism (1).
