Dr. Yash k. Khanna mentionned chest pain could be one of the side effects when you taking 5000 mcg of biotin. It is only allergic reaction or what?

Biotin is a Vitamin. I've never heard of biotin causing chest pain. Biotin is a vitamin, and i typically suggest 2, 500mcg of biotin for my patients with hair and nail abnormalities as a supplement. If you are having chest pain seek help from your primary care doctor or urgent care.
