What vitamins are essential to you?

I am 2 1/2 years out of an RNY and I take a calcium tablet w/D and a Pre-Natal vitamin that is it and my labs have been fine everytime. I am 69 years old and never have had a bit of trouble. I was told a pre-natal vitamin has everything you need. I take the extra calcium because of my age for strong bones, which I was taking before my RNY. Just make sure you eat right. A lot, a lot of PROTEIN!! Rosanne

I take multivitamins in multi-standard formula and 1 vitamin b12 sublingual in the form of methylcobalamin with 1000mcg.I get all these vitamins from vita4life.
