Antioxidants such as vitamins C and E, selenium and coenzyme Q10 have been shown to have beneficial effects on many aspects of human health. A recent study in Nutrition &Metabolism (July, 2010) showed that not only do antioxidants have significant beneficial effects on several aspects of cardiovascular disease, but may also help to improve blood glucose and lipid metabolism. In this study 70 people, each with at least two cardiovascular risk factors, were randomly assigned to two groups. For six months, one group received an antioxidant combination of vitamins C and E, selenium, and coenzyme Q10, while the other group received a placebo equivalent. The antioxidant treated participants showed significant decreases in blood pressure (both systolic and diastolic), increased levels of HDL (“good cholesterol”), and improvements in arterial elasticity and blood glucose levels. Although a preliminary study, the results help to support the need for antioxidant supplementation in this population.
