Vitamin E is a powerful antioxidant that prevents the oxidation of lipids. Since cell membranes are composed of lipids, it effectively prevents the cells' protective coatings from becoming rancid as a result of the assault of free radicals. Vitamin E also improves oxygen utilization, enhances immune response, plays a role in the prevention of cataracts caused by free radical damage, and may reduce the risk of coronary artery disease.
New evidence suggests that zinc is needed to maintain normal blood concentrations of vitamin E. Selenium enhances vitamin E uptake. These nutrients work well when taken together.
