|E 400IU 100% Natural, Non GMO. Vitamin E (D-alpha-tocopherol) is a fat-soluble vitamin and a powerful antioxidant, protecting cell membranes from pollution, toxins and free radicals.|
Most vitamin E supplements contain only alpha-tocopherol, or to be precise DL-alpha-tocopherol, which is a mixture of two optically different forms of alpha-tocopherol, D and L. Even though DL-alpha-tocopherol is perhaps sufficient to prevent vitamin E deficiency, it is not optimal for health when used alone. It is now believed that vitamin E represents a much wider family of related but distinct natural compounds including alpha, beta, delta and gamma tocopherols as well as alpha, beta, delta and gamma tocotrienols.
Alpha tocopherol, the main ingredient in most vitamin E supplements, is a well-documented antioxidant. However, every antioxidant has a limited range of targets, i.e. it is effective only against particular kinds of free radicals. Other tocopherols, beta, delta and most importantly gamma, are related but distinct compound with a somewhat different antioxidant range. They complement and enhance the activity of alpha tocopherol. Several studies indicate that mixed tocopherols are more effective than alpha tocopherol in quenching free radical and preventing disease. Notably, one study showed that high doses of alpha tocopherol taken alone reduced the blood levels of gamma tocopherols by 30-50%. This may explain why in some cases high doses of standard vitamin E supplements may do more harm than good. Indeed, it does not pay to fortify one wall of your castle with blocks taken from another wall.
Tocotrienols are also a part of vitamin E family. And perhaps the most important part at that. Tocotrienols are about 50 times more potent than tocopherols as antioxidants. They were shown to increase the life span of laboratory animals by about 20%. In human studies, tocotrienols showed an impressive promise in preventing and treating degenerative diseases. In one study, for instance, tocotrienols were shown to reverse the narrowing of the carotid artery due to atherosclerosis, an impressive feat for a noninvasive treatment. Similarly to tocopherols, tocotrienols come in alpha, beta, gamma and delta forms.
