Thank you Kitty, much appreciated. I have noticed great improvements too when I started taking biotin. I am nowhere near high dose and wonder if this is one of the instances where more means more. The doses seem scary high. I would think good kidneys are required.

If I have my math right, it would mean you taking 60 capsules of your 5000mcgs, every day
