A study reveals surprising evidence that antioxidants aren't always the panacea that we may think they are. While they have many positive benefits, recent studies at Kansas State University also suggest that they can cause harm in some circumstances. Too much of a good thing may be bad.
Scientists at the Kansas State University Cardiorespiratory Exercise Laboratory have studied ways to improve oxygen delivery to muscles during physical activity through the use of antioxidants. Steve Copp, a researcher in the lab states, "One of the things we've seen in our research is that you can't just give a larger dose of antioxidants and presume that there will be some sort of beneficial effect. In fact, you can actually make a problem worse." The researchers found that antioxidants can sometimes impair the function of muscles. Too many antioxidants can negatively impact the levels of oxidants, like hydrogen peroxide, which actually help to dilate blood vessels and increase blood and oxygen flow to muscles.
