quackwatch is a joke. if it isn't pharmaceutical/mainstream medicine, barrett slams it. most often he does so with little basis. please DO NOT take this guy's opinion as the truth, as he has a clear agenda of disparaging anything that is not the mainstream.i'm a phd candidate in public health at a major medical school, and am writing a dissertation on antioxidant vitamins. i know in reading his diatribes against vitamins that much of his work is very poorly researched.
at the end of the day, quackwatch is a closed-minded mainstream medicine propagandist. take what he says with a MAJOR grain of salt!
