Vitamins not always healthy

Here’s more evidence you shouldn’t load up willy-nilly on vitamin pills. Many people think if they exercise and take vitamins, they can prevent diabetes and other diseases. A new study has found that taking vitamins E and C actually blocks the beneficial effects of exercise.

A team of researchers from German and U.S. universities studied 39 healthy young men enrolled in a four-week exercise training program. Some took vitamins and some didn’t. Exercise had a beneficial effect on metabolism only in those who did not take the vitamins. “Individuals at risk for diabetes and maybe even some with type 2 diabetes itself need to think carefully about the use of these vitamin supplements, especially if they exercise regularly,” says Dr. C. Ronald Kahn from the Joslin Diabetes Center and Harvard Medical School.
