I've got a relatively simple question: what exactly is the difference between your average multivitamin for active individuals, such as One-A-Day and OneSource (the physically active ones) and something like Animal Pak or GNC's Mega Men? Best I can tell, you can get the same amount of vitamins and minerals by popping one of the cheaper ones twice a day than dropping $30+ on the "bodybuilding" multi's. Am I missing something here?
