Oxidized LDL cholesterol contributes to the development of atherosclerosis, which inhibits normal circulation of oxygenated blood to the tissues. Natural Factors Mixed Vitamin E contains d-alpha tocopherol, along with beta-, delta-, and gamma- tocopherols. D-alpha tocopherol, the most potent tocopherol, is natural and is more available for use in the body then its synthetic counterpart dl-alpha tocopherol. Mixed vitamin E tocopherols enhance the anti-inflammatory and antioxidant activity of a single tocopherol vitamin E.
