    Most individuals get adequate amounts of biotin through their diet and do not need supplementation. The adult U.S. Recommended Dietary Allowance (RDA) for biotin has not been established. The Adequate Intake (AI) has been established as between 7mcg and 35mcg daily, depending on age. If an individual is being treated for biotin deficiency, the recommended amount may vary and you should follow your doctor's orders. Biotin is thought to be non-toxic and doses up to 600 mcg have been established as safe.
