Vitamin E - Benefits, Deficiency Symptoms And Food Sources
By Alien
Vitamin E is a fat-soluble vitamin present in many foods, especially certain fats and oils. It is one of a number of nutrients called antioxidants. Some other well known antioxidants include vitamin C and beta-carotene. Antioxidants are nutrients that block some of the damage caused by toxic by-products released when the body transforms food into energy or fights off infection. The build up of these by-products over time is largely responsible for the aging process and can contribute to the development of various health conditions such as heart disease, cancer, and a host of inflammatory conditions like arthritis. Antioxidants provide some protection against these conditions and also help reduce the damage to the body caused by toxic chemicals and pollutants.
Vitamin E is a fat-soluble vitamin that exists in eight different forms. Each form has its own biological activity, which is the measure of potency or functional use in the body. It present in many foods, especially certain fats and oils. Some members of the vitamin E family are called tocopherols. These members include alpha tocopherol, beta tocopherol, gamma tocopherol, and delta tocopherol.
Functions and benefits of Vitamin E
Vitamin E, a fat-soluble vitamin, is an antioxidant vitamin involved in the metabolism of all cells. It protects vitamin A and essential fatty acids from oxidation in the body cells and prevents breakdown of body tissues.
The most important function of vitamin E is to maintain the integrity of the body's intracellular membrane by protecting its physical stability and providing a defense line against tissue damage caused by oxidation. It protects polyunsaturated fats and other oxygen-sensitive compounds such as vitamin A from being destroyed by damaging oxidation reactions. However, as with betacarotene, the effect of vitamin E in preventing heart disease may be both timing-sensitive and dose sensitive. Vitamin E may protect the liver and the rest of the body against environmental pollutants such as ozone and other constituents of smog. People receiving chemotherapy or radiation can also be protected with additional vitamin E supplementation.
Recommended Dosage for Vitamin E
The recommended dietary allowance (RDA) for vitamin E is quite low, 15 mg to 20 International Units (IU) per day. The most commonly prescribed dosage of supplemental vitamin E for adults is approximately 300 to 800 IU per day.
Food sources of Vitamin E

Deficiency Symptoms ...
{PS vitamin - Vitamin D - Recent reports show that populations around the world are suffering from vitamin D deficiency. The problem is widespread and increasing, with potentially severe repercussions for overall health and bone-fracture rates. There is evidence that suggests vitamin D deficiency increases during the winter months because of decreased exposure to sunlight, although vitamin D deficiency may also occur during the summer months. USANA's Vitamin D supplement is formulated with maximum strength vitamin D to ensure you get the vitamin D you need in one tablet.

... of Vitamin E
Vitamin E deficiency affects the central nervous system and may result in progressive neuromuscular disease characterized by loss of reflexes, muscle weakness, loss of balance and impaired ability to coordinate voluntary movements (ataxia). Premature infants who have a vitamin E deficiency are at risk of several serious disorders. They may develop a form of anemia in which red blood cells rupture (hemolytic anemia).
Vitamin E deficiency is rare in humans. There are three specific situations when a vitamin E deficiency is likely to occur.
1. persons who cannot absorb dietary fat due to an inability to secrete bile or with rare disorders of fat metabolism are at risk of vitamin E deficiency;
2. individuals with rare genetic abnormalities in the alpha-tocopherol transfer protein are at risk of vitamin E deficiency and
3. premature, very low birth weight infants are at risk of vitamin E deficiency.
Blood levels of vitamin E may also be decreased with zinc deficiency. Vitamin E deficiency is usually characterized by neurological problems associated with nerve degeneration in hands and feet. These symptoms are also associated with other medical conditions.
