    Test Description

    Vitamin E

    Vitamin E is a fat-soluble vitamin. There are eight forms of vitamin E, however, the most biologically active form is d-alpha-tocopherol. The best defined role for vitamin E is an antioxidant for unsaturated fatty acids in cell membranes. It is also important in energy metabolism and synthesis of RNA, DNA, and red blood cells. It acts as an antioxidant in the lungs against smog. Vitamin E is absorbed in the presence of bile in the small intestine. Deficiency of vitamin E may result in hemolysis of RBC's, sterility, higher risk for heart disease and stroke.

    The RDA is 22 I.U. A suggested supplemental range is 100 to 1000 I.U. A toxic range has not been established, but 4000 I.U. and higher should be taken with caution.
