My gut feel, based on a BS Chem and then casual reading, has been that the occasional vitamin is best. Keep a bottle in the cupboard, take a one when you feel like it (no more than once a week). Replace the bottle when it expires. Chances are you don't need it, and I think the body is really good at snatching up things it needs when that pill rolls by. (I worried about the kidney/etc burden of daily excess, but the idea that daily excess could spur excess in the form of cancer does not surprise.)
