Summary
Coronary heart disease is a narrowing or blockage of the coronary arteries usually caused by the buildup of plaque. In this study, Turkish scientists investigated the vasodilatory effect of vitamin C (ascorbic acid) and vitamin E (α-tocopherol) – i.e., their ability to widen blood vessels – in patients with coronary heart disease. For this purpose, participants were divided into three groups of 31 subjects each: the first group received 2 g of vitamin C and the second 2 g of vitamin C plus 600 mg of vitamin E; the third group received no supplement. The results showed that vitamin C in combination with vitamin E contributed to vasodilation in patients with coronary artery disease. You can find more information in the study.
