Title: Lower dose sufficient; great for nails
Review: A 1000mcg dose seems to work exactly the same as the 5000mcg dose, based on many months of experience taking biotin daily. There's no difference so there's not much point in megadosing. My nails are much harder, stronger, and grow faster, but while my hair grows much faster too (not twice as fast, but probably close to it!), it has not gotten any thicker, which is what I was hoping for. Bummer! I just started taking a multivitamin with 400mcg biotin so when I run out of biotin-only pills, I won't bother with restocking.
