Taking antioxidant supplements -- specifically, vitamin C and vitamin E pills -- may dull one of the benefits of exercise, new research shows.
The new study shows that when healthy men took vitamin C and vitamin E supplements daily during a month of exercise, their insulin sensitivity didn't improve, though other men following the same exercise plan and taking placebo pills did improve their insulin sensitivity.
The antioxidant supplements shut down the brief, normal spike in oxidation that follows exercise; that temporary bout of oxidation is needed to improve insulin sensitivity, according to the researchers, who included Michael Ristow, MD, chair of the department of human nutrition at Germany's University of Jena.
Do Antioxidants Curb an Exercise Benefit?
Thoughts? At the very least this makes me wonder about taking ALA with my post workout protein/carbs. Perhaps I should wait and take it prior to a later meal outside that PWO window.
