Vitamin E is an umbrella term for eight fat-soluble compounds with definite antioxidant qualities. Four of the eight are called tocopherols; the other four are known as tocotrienols.
Both tocopherols and tocotrienols exist in four forms alpha, beta, gamma and delta. Each form has its own biological function and potency, but of the eight, alpha-tocopherol is the most active type of Vitamin E in humans, and the only one maintained in human blood circulation.
Vitamin E is absorbed into the lymph with fat and bile salt from the intestines, and then is picked up by the blood stream and carried to the liver, where it is used immediately or stored. Vitamin E serves as a co-enzyme in cellular membranes, and acts as a scavenger for free radicals destructive to internal cellular components.
As a whole, Vitamin E is the most effective, fat-soluble antioxidant known to the human body. It is found naturally in some foods and added to others.
Vitamin E is an essential nutrient crucial for good health.
- Vitamin E is an intelligent choice to help ensure a sufficient daily intake of the heart-health supplements you need most.
- Some people, including those on low-fat diets, may not be meeting the recommended daily intake for Vitamin E.
- Topical Vitamin E can be absorbed through the skin.
- Studies support the ability of Vitamin E to promote antioxidant health.
- Vitamin E is a powerful antioxidant that helps fight cell-damaging free radicals in the body.
- Vitamin E promotes the health of your cardiovascular system.
- Studies support the ability of Vitamin E to promote heart health.
- Vitamin E's antioxidant properties support skin health.
- Vitamin E helps maintain a healthy immune system.
- Free radicals can contribute to oxidative stress, which in turn may contribute to the premature aging of cells.
The key function of Vitamin E is to protect the physical stability of the body's intracellular membrane, and help defend against tissue damage caused by oxidation. Vitamin E lessens the oxidation of lipid membranes and fatty acids, thereby reducing cellular damage.
Vitamin E is also a powerful antioxidant which helps stabilize cell membranes and protect tissue which is more sensitive to oxidation, such as the skin, eyes, liver, breast, and testes. When applied to the skin, creams and oils containing Vitamin E are believed to promote skin health and maintenance. The benefits of the antioxidant qualities of Vitamin E are enhanced by other antioxidants such as Vitamin C, beta-carotene, glutathione(L-cysteine), and the mineral selenium.
Fortunately, numerous foods provide Vitamin E. Nuts, seeds, and vegetable oils are especially rich sources of alpha-tocopherol, and significant amounts are available in green leafy vegetables and fortified cereals, as well.
