Immune system improvement occurred in other areas also. Most multivitamins contain d-Alpha tocopherol or d,l Alpha tocopherol. Studies show that Alpha tocopherol is only part of the story. A full range of antioxidant protection can only be achieved by using other tocopherols as well. In fact, recent studies show that it can be dangerous to take large amounts of Alpha tocopherol without the other fractions in much the same way as it is dangerous to take large amounts of Beta carotene without other carotenoids.
Different fractions work together.
Alpha tocopherol can displace Gamma tocopherol in tissues. While Alpha tocopherol inhibits the production of free radicals to some degree, it is Gamma Tocopherol that is required to trap and neutralize existing free radicals. Tocotrienol is 40 to 6000 times stronger as an antioxidant than Vitamin E, depending upon the tocopherol fraction. Since it is oxidized cholesterol that causes atherosclerosis this is a considerable advantage. Many alternative healers are now recommending Tocotrienol instead of FDA-approved drugs for hypercholesterolemia.
