Vitamins 'undo exercise efforts'

Plausible. In fact, downright very probably correct.

"Taking vitamins after exercise may undo some of the beneficial effects of the workout, research suggests.

Some advocate taking antioxidants like vitamin C and E to help protect the body from harmful chemical by-products it creates in breaking into a sweat.

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

And mopping them up with antioxidants may do more harm than good."

The data seem quite clear that "exercise" results in the creation of free radicals.

Also, the body has its own mechanisms in place for removing these items.

If you are interested, see a basic physiology text like: Brooks GA, Fahey TD, Baldwin KM. Exercise Physiology: Human Bioenergetics and Its Applications (4th ed). New York, NY: McGraw-Hill 2005.

People throw this antioxidant stuff into their bodies with no idea of what they are really doing.

The reports remain in conflict. See here and here.

Still think they have any idea what they are talking about?
