Nowadays, everything from bottled water to orange juice seems to have souped-up levels of vitamins and minerals in it. That may sound like a way to help cover your nutritional bases, especially if your diet is less than stellar.  But routinely getting an overload of vitamins and minerals can hurt you. Too much vitamin C or zinc could cause nausea, diarrhea, and stomachcramps. Too much selenium could lead to hair loss, gastrointestinal upset, fatigue, and mild nerve damage.- Web MD

Recent research suggests that taking massive daily doses of vitamins like C and E can be counterproductive

In Shakespeare’s As You Like It Rosalind asks, “ … can one desire too much of a good thing?”

That’s just what investigators wanted to know when they spent 11 weeks monitoring 54 young men and women in an endurance training program. They gave half the participants 1000mg vitamin C and 235mg vitamin E daily. The other half received sugar pills or placebos.

In the end, guess who had signs of greater energy and muscle strength (more mitochondrial proteins, vital for building new muscle and fueling cells?) Only the folks who took the placebo!

Can you take too much of a vitamin supplement? Yes. It turns out that a daily dose of vitamin C equivalent to eating as many as 28 oranges and taking 15 times the dietary reference intake of vitamin E may be counterproductive.

So if you’re working out, we suggest you look at your multivitamin: Make sure it doesn’t give you doses much above 100 percent of most nutrients’ recommended intake………
