Most women were raised to think vitamin supplements are necessary for good health. But when it comes to heart health, large studies have proven otherwise. "You dont need vitamin supplements for your heart-not multivitamins, not individual vitamin supplements," says Cleveland Clinic cardiologist Leslie Cho, MD. Vitamins A, C, E and beta-carotene are antioxidants that protect cells from damage that can cause cardiovascular disease. Eating a diet high in antioxidants can decrease the risk of cardiovascular disease. However, recent studies have found no evidence that supplementation with these vitamins has the same effect.
