Personally, I think everyone should be on a multivitamin.
I currently take GNC Women's Ultra Mega but I wouldn't suggest that for you, LOL.
I'm with Aaron on this one though, I've heard nothing but postive about Animal Pak, everyone I know that's used it has loved it and won't switch.
And again, like Aaron said, Zupplements.com has a great price on it. You can get nearly a months worth (depends on how you take it, one pak a day is what's suggested) for $18.
