Moderate dose (as defined with respect to RDA, which is by definition insufficent to avoid all symptoms of deficiency), the subjects did not change their poor diets (which may have wholly consumed the antioxidants ingested, on a day-to-day basis), the trial was only for 90 days, and there were limited assays of antioxidant effect (the body definitely prioritizes nutrient allocation).

Ya might want to subscribe to the sci.life-extension news group, as there is frequently some interesting scientific discussion of these issues. There are some valuable contributers such as Aubrey De Grey, Steve Harris, Peter Proctor, and others.
