Yes, totally safe: Biotin is extremely safe, in fact there is absolutely no known toxicity from any amount of biotin. 5000 mcg may sound like a lot, but it's the same as 5 mg, which may not sound like much. Whether it helps you is another question; it will help if you are deficient but deficiency is uncommon. Advise continuing the Skin, Hair and Nails vitamin too.
