Supplements may negate benefits of exercise

Many exercise enthusiasts take vitamins after a workout in hopes of protecting the body from harmful chemicals produced when sweating. But new research suggests taking supplements after exercise may actually undo some of the beneficial effects. German scientists from the University of Jena say free radicals could play a positive role and even buffer against diabetes.

Does that mean vitamins like C and E are bad for us?

Not necessarily. But researchers say their study suggests we may need to consider whether taking supplements is actually beneficial.
