Supplements of antioxidant vitamins after exercise may decrease the benefits of the workout by blocking the positive effects of reactive oxygen, says a new study.
Researchers from Germany and the US report in the Proceedings of the National Academy of Sciences that a combination of 1,000 mg per day of vitamin C and 400 IU per day of vitamin E adversely affected insulin sensitivity, and thereby increase the risk of type 2 diabetes.
Read the whole thing for arguments on both sides of the issue. I do agree with this paragraph though( That it makes sense that the "whole food" route would be better. Something like COq10, imo, is good to take separately as well though):
“A significant number of studies have shown that fruits and vegetables promote health, while antioxidant supplements do not. This insinuates that fruits and vegetables are healthy despite their content in antioxidants, and that other compound contained within these are responsible for these health-promoting effects of fruits and vegetables,” he added.
