Vitamin E

Vitamin E has also been in the news today. In fact on the evening news with Katie Couric the other day a doctor stated there is no scientific proof that any vitamin supplements do any good. Evidently he doesn’t read medical journals today.

Vitamin E is a generic term for a group of related compounds called tocopherols, which occur in four major forms: alpha, beta, delta, and gamma-tocopherols. Alpha-tocopherol is the most common and most potent form. Being fat-soluble, vitamin E is stored for long periods of time, mainly in the fat tissue and liver.

Vitamin E is found in only a few foods and many of these are high in fat.

One of vitamin E’s basic functions is to protect cell membranes, and it also helps the body use selenium and vitamin K. Currently vitamin E is known for it’s antioxidant abilities. Because is protects from free radical damage, some experts believe that vitamin E may slow the aging process,

The RDA for vitamin E is 15 mg (in the form of alpha-tocopherol) for all adults but higher doses are needed to work as an antioxidant.

Too little vitamin E can lead to neurological damage and can shorten the life of red blood cells. Too much may cause the risk of bleeding. Large doses of vitamin E can interfere with the absorption of vitamin A.

To obtain the disease-fighting potential of vitamin E, experts recommend 400 to 1,000 IU daily in capsule or tablet. 

Wheat germ is a great dietary source of vitamin E. Nuts, seeds, green leafy vegetables and whole grains are also a good source for vitamin E.
