Antioxidant supplements for prevention of mortality in healthy participants and patients with various diseases - The Cochrane Library

 Abstract

"The increased risk of mortality was associated with beta-carotene and possibly vitamin E and vitamin A, but was not associated with the use of vitamin C or selenium. The current evidence does not support the use of antioxidant supplements in the general population or in patients with various diseases."

Background

Our systematic review has demonstrated that antioxidant supplements may increase mortality. We have now updated this review.

Objectives

To assess the beneficial and harmful effects of antioxidant supplements for prevention of mortality in adults.
