Who Needs Antioxidants? No One.
Perhaps the most damning evidence against the Free Radical/Oxidative Stress Theory of Aging is that after 60 years of intensive research into antioxidants, with billions of dollars spent looking for nutrients that can retard cell aging, not a single antioxidant compound has been found that can extend human life. In fact, in a shocking number of human trials, antioxidants (beta carotene, Vitamin E, Vitamin A) have actually increased all-cause mortality.
