What are the side effects or risks of taking biotin?

ANSWER

Biotin seems to be safe and well-tolerated, even at fairly high levels. The maximum safe dose of biotin is unknown. If you have any medical conditions -- or are pregnant or breastfeeding -- check with a doctor before using biotin supplements. Don't give biotin to a child unless a pediatrician recommends it.
