I would like to read the specifics of research.

>From the article, they mentioned "moderate doses."  Since I'm not sure what exactly they mean, I think it's premature to just to the conclusion of "[o]nce again: Some vitamins don't help in large doses."  Without knowing more details -- were the young men in good health? what were their ages? how often did they exercise? how long did the study last? what were the doses and how often? what types of C and E were used? -- this looks like more little more than another typical hit-and-run attack on supplements.  I mean most people will trust the NY Times, but this story lacks the context where an informed person might judge whether the claims made are valid and whether to stop using these two micronutrients.
