Vitamins: awesome or useless?
Really simple question that I've been wondering about for a while: does something like a daily, generic multivitamin have any tangible effect on health? Does it depend largely on what your diet looks like? Is it a particularly good idea to take one if you're on a solid workout routine?
I ask because I've heard a range of opinions on this, ranging from "A multivitamin is essential if you're working out regularly" to "a vitamin buys you nothing except for expensive urine".
