How many do you have to take and how many do you choose to take? (And for privacy's sake, you don't have to say what they are and what they do if you don't want to.) There's one, no matter what, I have to take. Then there are some that I don't necessarily 'have' to take, but I feel better about taking them: 2 One A Days 2 Vitamin D pills 3 Calcium chews I don't eat that many fruits and vegetables, so the pills make up for the nutrients I don't normally otherwise get. (Also, I don't much like the sun. I don't have the skin for it, so the Vitamin D makes it so I don't have to go out into the sun).
