The evidence in words
Safety profile
Safe, but the lab-test interference is a real clinical hazard — disclose supplementation before testing.
Interactions to respect
No major interactions are on record for Biotin (B7) at typical doses, but tell your clinician about everything you take.
What Biotin (B7) is
Biotin (vitamin B7) is a coenzyme in fatty-acid and glucose metabolism, marketed heavily for hair, skin, and nails.
The honest bottom line
Skip it for hair unless you're deficient — and always tell the lab, because high-dose biotin falsifies thyroid and cardiac tests.
