Vitamin E (Alpha tocopherol)  

General description
Vitamin E is a member of the family of fat-soluble antioxidant nutrients known
as tocopherols. Alpha tocopherol is the most active of the tocopherols in terms
of vitamin E activity, but beta, delta, and gamma tocopherols have antioxidant
capabilities as well. Another closely related group of compounds, the
tocotrienols also exhibit antioxidant properties. Many nutritionists recommend
natural-source supplements that include a mix of tocopherols and tocotrienols,
because these compounds are believed to complement each other's activity.
Supplemental vitamin E is available in natural and synthetic forms, with the
more potent, natural forms distinguished by a "d" (d-alpha tocopherol) while
synthetic forms are indicated by "dl" (dl-alpha tocopherol).

Food sources
The best food sources of vitamin E include vegetable oils, nuts, seeds, whole
grains, and wheat germ. Other sources include asparagus, avocado, green
leafy vegetables, and tomatoes.

Functions and uses
Vitamin E plays many vital roles in organs and systems throughout the body,
from the immune system to the brain, skin, eyes, liver, and heart. As a
fat-soluble nutrient, vitamin E is incorporated into the lipid portions of cell
membranes, where it helps protect these structures from free-radical induced
damage. As an antioxidant, vitamin E helps protect LDL cholesterol molecules
from oxidation, which is especially beneficial for cardiovascular health.

Dosage/toxicity
While the 15 IU per day RDA for vitamin E is sufficient to prevent overt
deficiency, the most commonly recommended dose of vitamin E is 400 IU per
day. Many dietary factors affect the body's vitamin E requirements. A diet high
in saturated fats increases vitamin E requirements. Other nutrients like vitamin
C and selenium can increase the antioxidant potential of vitamin E. Vitamin E is
very safe, with adverse effects being rare even at doses as high as 3,200 IU per
day.3
