Maybe: That's a ridiculously high dose of biotin. The only indication to take biotin is if you have a true biotin deficiency. And in that case the dose is 100-1000 mcg daily. The dose you are taking is high, but there are no real documented side effects. Likely the majority of that dose will be excreted.
