I take calcium, because I know I don't get enough in my diet. And I take a multivitamin with folate, because I'm eyeing getting preggers and want to have good stores before even trying to conceive. Everything else I get (prolly in excess!) in my diet. I take cheap@$$ generics from reputable companies -- and I think my biggest nonvitamin simple solution is washing my hands a LOT during viral season (which, for me in an ER seeing kids, is *all*year*round*)!
