Taking antioxidant supplements reduce the chances for cardiovascular disease

This review of 20 studies covering 1,909 people measured the effects of taking the antioxidant vitamins A, C, E and beta-carotene, alone or combined, on arterial stiffness, compared to placebo.

Healthy people of any age who had taken any one of these antioxidants alone or together in any combination, for any length of time, had lower chances of developing arterial stiffness compared to placebo. Doctors also saw improvement among those with existing arterial stiffness who took vitamins compared to placebo. Overall, combining results from all 20 studies, taking antioxidant supplements reduced the chances for cardiovascular disease by 4.7 percent. Doctors concluded that taking antioxidant vitamins has a small, protective effect on arterial stiffness.
