Vitamins

Hello =] !
I was watching something on tv today, about how we should be taking vitamins/minerals to keep our body healthy and to fight diseases and such.
Now I am  a total believer in this. I usually tend to stick with the natural approach with most things, unless things get out of hand and I need some drugs =P.  I actually BARELY go to visit the doctor UNLESS it is totally necessary. You know, I actually haven't seen the doctor for maybe about 10 years now and I'm perfectly fine. I cured my own darn fever in ONE day!! lol crazy but true.
I also take supplements to keep me healthy and beeeeeeeeee-youuuu-teeeeeee-full =P hehe. I usually take 2 vitamin C pills ( 4-5 if I am sick or feeling a little under the weather), 2 calcium + magnesium pills, 1 daily vitamin (forgot what it's called, one with all the nutrients in it hahah) and you cannot forgot your fish oils!!!!! 2 fish oil pills daily. Yupppp that's what I take and completely feel like it benefits me.
So I was wondering, do you guys believe in vitamins and how they can help you? If so, what do you take? how much?
