Vitamin E is a fat-soluble vitamin essential for health. It is also known as alpha tocopherol (α- tocopherol). Being a powerful antioxidant, Vitamin E helps maintain healthy cells by protecting them from free radical damage. It is also beneficial for healthy skin and good eyesight. On-going research says it is beneficial for heart health, since it helps clear blocked arteries and lowers high blood pressure

Functions:
1.    As an antioxidant, Vitamin E protects against tissue damage. It helps fight against free radicals. This keeps tissues and organs healthy, thereby preventing premature ageing. Vitamin E disables the production of damaging free radicals in tissues. These are then reduced by another vitamin, like vitamin C.
2.    Vitamin E fights against bacteria and viruses, keeping the immune system healthy and strong
3.    It helps the body use Vitamin K efficiently. 
4.    Vitamin E helps in blood clotting and in the formation of new red blood cells. For heart health, it repairs wounds and regenerates tissue lost or damaged during atherosclerosis
5.    On a cellular level, Vitamin E helps regulate cell interactions and helps with their optimal functioning
6.    Vitamin E prevents the oxidation of polyunsaturated fatty acids. This prevents spoilage.

Food Sources:

Vitamin E is found in foods, the best way to get a sufficient amount is to have a balanced and healthy diet.

It can be obtained from vegetable oils like sunflower, safflower, corn and soybean oils. Nuts and seeds like sunflower seeds, almonds, groundnuts and hazelnuts also contain Vitamin E. Green leafy vegetables - spinach and broccoli and fortified foods like cereals and fruit juices

Deficiency:

Deficiency causes muscle weakness, night blindness, fibroplasia of the retina, growth retardation, liver disease, weight loss and loss of appetite.

To include vitamin E as part of your diet, you can add sunflower seeds or nuts like almonds for a healthy on the go snack. Cooking with sunflower oil also provides Vitamin E, you can sauté spinach and broccoli in sunflower oil for added benefits!

Word of caution:
For a healthy individual, without a Vitamin E deficiency, taking excess of the vitamin can act as an anticoagulant, increasing the risk of bleeding. This is a matter of concern especially if one is on warfarin (a blood thinner)

More than 1000 mg per day increases the risk of Hypervitaminosis E. This can work against vitamin K, leading to a vitamin K deficiency.

Ironically despite being an antioxidant, excess amounts of Vitamin E can cause it to obtain prooxidant properties. This can cause cell damage, increasing cancer risk and even death.

Need a concluding line here I think (especially after stating the toxicity).
