Vitamins

Do vitamins really do anything? I realize it's a multi-billion dollar industry but is there any PROOF that these pills do anything but shrink your wallet. Skeptic? Me? Nope. My Grandmother swore by the things. She had a routine, that as a kid, I'd love to watch. She would pull down the shoe box filled with bottles and pull her "stash" for the day; B complex, Cod Liver, Zinc, etc. She lived to be 100 years old! That should say something. My question is, does anyone have a way to prove that any combination of pills really work. Do we have the placebo effect? I take a multivitamin because it will make me have more energy and "feel" more healthy. Do I truly get more energy or do I just trick myself into it because I take the vitamin.

Judging from my wife's comments about laying around all weekend watching sports on TV, maybe I set the "energy" bar a bit high. OR maybe I just don't feel like doing anything on the weekend. Yeah, that must be it. I need to store my energy for the work week. Imagine how much energy I must store up on a three day weekend.
