Vitamin E is a fat-soluble vitamin that is proven to be the best antioxidant; an agent helps to protect the body from the free radicals.

Vitamin E is very important factor for the body since its deficiency can cause nervous disorders and it can also lead to some health ailments related to the eyes. However, the deficiency of the Vitamin E, luckily, is very rare but then too; low levels of Vitamin E can cause hemolytic anemia. The deficiency is generally found in the people who cannot absorb the fats normally. This is because Vitamin E is fat-soluble and hence, needs dietary fats to get absorbed.

This Vitamin exists in eight different forms and each of them has its own biological activities that are measured of potency or functional usage in the human body. In humans, the most active form of the Vitamin E is known as Alpha-tocopherol and hence Vitamin E supplements are generally sold as Alpha-tocopheryl acetate, which is a form of alpha-tocopherol. It has capability to act as powerful antioxidant. Antioxidants are very necessary to save body cells from free radicals. Free radicals are obvious to present in the body since they are the byproducts of energy metabolism of the body.

Fortunately, Vitamin E can be found in abandon quantity in many foods we eat. Vegetable oils are one of the best sources of Vitamin E. Other common sources of the Vitamin include nuts, green leafy vegetables and fortified cereals. Wheat germ, sesame seeds, peanuts and sunflower seeds are few of the great sources of Vitamin E. Recommended Dietary Allowance (RDA) for Vitamin E is about 15-20 mg (i.e. 22.5-28.5 IU) a day. About 90% of the Vitamin E is stored in the adipose tissues (fatty tissues) in the body and rest of it is stored in the cell membranes.

The human body is made up of zillions of cells and the cells make an organ. Many organs make body systems. The wellbeing and optimum health is the result of plenty of successful bodily chemical reactions. Vitamin E is also considered to be an agent that can inhibit the activities of protein kinase C. It also affects the expressions and activities of immune and inflammatory cells. Vitamin E is also known to protect polyunsaturated fatty acids (PUFA) from oxidation since it destroys peroxyl radicals. Vitamin E can inhibit platelet aggregation and the Vitamin is also involved in signal transduction in the nerve cells because the Vitamin is closely linked with nerve cell membranes and other lipids related to the nervous system of the human body.

There are many researches that favor that natural Vitamin E can dramatically reduce the heart diseases and other heart related problems. It can reduce cardiovascular death and/or serious cardiovascular disease very significantly as studied in a randomized, double-blind, placebo-controlled trials. Some of the clinical trials also favor Vitamin E as an agent that can help in cataracts, cancerous growth, muscular pains and strains. Topically, this Vitamin can enhance the beauty and hence, in many cosmetic products, Vitamin E has been used. Vitamin E can also be supplied as dietary health supplements generally as gelatin capsules.
