Vitamins after exercise can undo efforts

12th May 2009

Research suggests taking vitamins after exercise could undo some beneficial effects of the workout.

Some people take vitamins C and E to help protect body against chemical by-products it creates in breaking into a sweat.

However, German scientists now believe "free radicals" may actually be good for us and even buffer against diabetes, PNAS reports.

Mopping them up with antioxidants like vitamins C and E may do more harm than good.

Dr Michael Ristow and his team, at the University of Jena, have shown free radicals may have a positive effect on the body by increasing its sensitivity to insulin.

This effect is blocked by antioxidant vitamins.

Dr Elisabeth Weichselbaum of the British Nutrition Foundation said: "Antioxidants protect the cells in your body from damage and therefore help to reduce the risk of certain diseases such as cancer.

"But you should not consume high doses on a regular basis as this can have negative effects on your body.

"If you stick to a healthy and varied diet, you generally get enough of the nutrients you need and you don't run the risk of consuming large amounts that may be harmful for you."
