You've probably noticed that you can buy vitamins and minerals at your local supermarket and your local drugstore as well as at health food stores. You may have thought that maybe the vitamins and minerals in the health food stores were in some way better or were higher quality? Or maybe you've just assumed that the ones in the supermarket or drugstore are just as good?
Well, funnily enough, you were right - except for one thing, neither of them are good for you, especially over the long term. How come?
