Although this dose is way above the RDA for biotin it is a common and often effective recommendation for the support of hair and nail growth. No significant toxicity has been documented in the oral use of biotin even in doses much higher than 5mg. It is rapidly metabolized and excreted in the urine.
Is it safe to take a daily dose of 5000 mcg of Biotin for the sole purpose of improving the quality of hair and nails?
