Whats the difference between regular multivitamins and the hair skin and nails vitamins? i decided to check out the vitamin section while i was waiting in walgreens and I notice that a lot of the stuff that was in the hair skin and nail vitamins was already in my adult multivitamins- actually in a greater amount. Why does everyone take so many extra vitamins when you can just buy a regular supplement and get everything you need (like the B's, C's, E's, ect.)? I'm not attacking anyone
, im just curious. And what do amino acids do and what are the names for them?
