Biotin: Hi, Biotin is a cofactor for Vitamin B group and is water soluble and it excess can be excreted from body by kidney so I don't think it could cause any problem and toxicity, I don't think Biotin has side effects if the kidney is working fine, although I saw the other day a colleague said it could cause skin breakout so I did a search and I couldn;t find any scientific evidence.
