What do vitamin A, B, C, D, E do for you?

Go here and click on each vitamin for more info

The purpose of vitamins is to regulate a variety of different organic processes that take place in the body of humans. Some of the body’s enzymes need particular vitamins to do their work.

The MDR varies with diet, age, general health (weight, good habits or not) and genes.

You have to google each vitamin, learn what foods would provide you with that specific vitamin, and see when or whether supps. are necessary.

Vit. D is the most difficult to get from food. Most people now are taking a D3 supplement. I am taking 4000IU daily and a sublingual 50 mg. B12. Too much A is bad for someone in my age bracket.

Now, go thou and do research.

Make your urine more fortified. There is very little evidence to support that taking vitamins over and above what is in your food makes any clinical difference whatsoever.

@Rarebear: What about the ongoing debate over D3?

@gailcalled Okay, I stand corrected. In certain circumstances taking a targeted supplemental vitamin such as Vitamin D for dark skinned people in low sun climates is beneficial. But the questioner was asking about working out, so I just assumed that s/he wanted vitamins to help with the workout regimen.

@Rarebear: True about the questioner. I got sidetracked. Can one assume that anyone strong enough to work out regularly knows something about proper nutrition? Probably not.

My family is light-skinned and burns very easily; we never (like mad dogs and Englishmen) go out in the noon day sun.

Most nutrition experts will tell you the healthiest way to get the proper balance of nutrients is to eat properly, not by taking supplements. Talk to your trainer or doctor and follow a good eating/exercise plan.
