Can you give examples of pharmacy grade vitamins?
I'm not a crazy supplement guy, I just think it's wise to know what to eat, and then make sure that gets backed up with supplements for those times when maybe you are depleted, or traveling on business and a good diet goes to hell.
I 've used these guys in the past, I THINK they are still independent, but of course all of life is buyer beware, so always best to go w/what a doctor (can't even trust them that much these days since they may just be pushing what's been recommended to them) or a good nutritionist.
