As far as I know, there is no evidence to suggest that a vitamin supplement will provide health benefits to an otherwise healthy individual. Some doctors even say it only makes "expensive urine." Still, I started taking a "once a day" vitamin supplement today. I'll take it until it runs out and see if it makes me feel any healthier. I think it might work as a placebo as I already feel the vitamins and minerals pumping throughout my veins making me stronger and healthier.
