Ester-E® is an advanced, natural, and highly bioactive form of vitamin E that occurs when natural D-alpha tocopherol combines with a phosphate molecule. Initial animal studies indicate that Ester-E's absorption may exceed that of the tocopherol and acetate forms. Vitamin E is one of the body's chief antioxidants and the phosphate form, Ester-E, offers advanced antioxidant protection to body cells, helps maintain cardiovascular health, protects the liver from toxins, enhances circulation and supports healthy immune system function.
