Question: Am I consuming too much biotin?
ANSWER: If you are taking over 5mg/5,000mcg of biotin per day, then I would try to eliminate a biotin source. I have known too many people consuming 10,000 mcg, 12,000mcg and up of biotin (superbiotin) per day. It seems to cause other health and/or hair challenges. Side effects vary. If you are taking a multi-vitamin, a "hair, nails, and skin" vitamin, meal replacement shake (i.e. Herbalife), and taking an additional 5,000 mcg of biotin capsule, then you need to add up how much biotin that you are really consuming. You may need to reduce the "extra biotin" to 1,000 mcg if you are getting the Daily Value of Biotin from other sources.
