I was getting way sick of Flintstones Complete (would gag them down) so when I was returning some Isopure Zero Carb Strawberries&Cream, I asked about multi-vitamins. The Mega Teen require 3 a day, but they're not as huge as a lot of vitamins. So I don't feel uncomfortable taking them. I'm going to work my way up to taking a one a day formula, but it'll be awhile before I get brave. Heh.
