I've heard a lot of people saying you should take multi-vitamins. How good are they really? I'm only 19, and I'm not sure if my body really needs it. Is it not true that my body might get used to the Multi-Vits and depend on them for the vitamins that it gets from them? Also, what Multi-Vits are good to take. I know Centrum is very popular, but don't know if it's mostly for older people. What do you guys take?

Thnx
