The Women’s Antioxidant and Folic Acid Cardiovascular Study (also known as the Women’s Antioxidant Cardiovascular Study [WACS]) was a randomized, double-blind, placebo-controlled trial evaluating several micronutrients—vitamin E, vitamin C, beta-carotene, and a combined supplement of folic acid, vitamin B6 and vitamin B12—in the prevention of cardiovascular disease events among women at high risk of such events, either because they had a prior history of cardiovascular disease or because they had three or more major risk factors for cardiovascular disease (8,171 women in the vitamin E, vitamin C, and beta-carotene components and 5,442 women in the folic acid/B vitamin component). The trial also examined whether these micronutrients are useful in preventing cancer, vision problems, and cognitive decline.
