People who are into alternative medicine already know that mega doses of antioxidants might be harmful, just like megadoses of other vitamins, sugar, alcohol, junk food, artificial sweeteners, etc. might be harmful, too.
However, administered under the supervision of someone who knows what they are doing, antioxidants and other vitamins/minerals/herbs can also help immensely. So anyone who wants to use high doses of antioxidant supplements (which are specific
supplements, btw, not just "vitamins") or any other supplements for that matter, should always do so under the care of their chosen health care professional, and of course, always use the best quality ingredients.
I've seen people who have been helped tremendously from antioxidant therapy. One friend received specific treatments from an holistic MD while she was going through chemo for ovarian cancer, and she had a very easy time of it, compared other people I've personally known who went through chemo. She is now cancer-free.
So I feel that for me to dismiss larger doses antioxidants across the board due to a study that I am not able to read without paying for it, and therefore do not know the specifics, would be premature. That is the problem with some of these studies. People read the headlines and a short article, and never actually read the study itself, then they assume they have all the info they need to make a decision.
