How do you expect your body to function at optimal levels if you are deficient in minerals and vitamins? Do you think Antioxidants are useless also? Each of those vitamins and minerals serves a purpose in your body.
And you're recommending just 1 mineral, vanadryl, that has been shown to work only when you reach a level of it that is near toxic, makes no sense to me. Not a shot at you, just wonder where you're coming from w/ this.
