Hope that helps.
I cosign this. Centrum, One-A-Day, and pretty much the ones you find at your local drugstore are synthetic vitamins and they make me vomit too. I take Rainbow Light as my food-based multivitamin and it never makes me feel sick.
My nutritionist and doctor said that many people have issues with synthetics.
