Vitamin E Sources and Functions: Facts of Vitamin E

Sources of Vitamin E

  1. The richest sources of vitamin E are cold-pressed crude vegetable oils, especially wheat germ, sunflower seeds, safflower, and soya bean oils.
  2. Eggs, butter, raw or sprouted seeds, and grains – especially whole wheat – are moderately good sources.
  3. Meats, fruits, and green leafy vegetables provide small quantities of this vitamin.

Functions of Vitamin E

  1. The main functions and benefits of vitamin E are to help protect the functioning of cells and the intracellular processes.
  2. Vitamin E oxygenates the tissues and reduces the need for oxygen intake markedly.
  3. Vitamin E is essential for normal reproductive functions, fertility, and physical vigor.
  4. Vitamin E prevents unsaturated fatty acids, sex hormones, and fat-soluble vitamins from being destroyed in the body by oxygen.
  5. Vitamin E dilates the capillaries and enables the blood to flow freely into blood-deficient muscle tissue, thus strengthening both the tissues and the nerves supplying them. It dissolves blood clots and also prevents their formation. It does not, however, interfere with the normal clotting of blood.
  6. It prevents the formation of excessive scar tissues and in some instances, even melts away unwanted scar tissue. It also promotes urine secretion. Vitamin E is said to be essential for prevention of heart disease, asthma, arthritis, and many other conditions.

Vitamin E Facts

In 1923 Herbert Evans and Katherine Bishop in California, USA, discovered that there existed a dietary factor which was essential for reproduction in rats. It was given the name vitamin E or antisterility factor by Dr E. V. Shute in 1924. It was, however, only in 1936 that Evans and his colleagues finally isolated pure vitamin E from wheat-germ oil. They called it tocopherol. This word is derived from locos meaning child birth, and pheros meaning to bear.

Eight different tocopherol compounds with vitamin E activity have been identified uptil now. All of them have the same physiological properties. The tocopherols are yellow, oily liquids, freely soluble in fat solvents. They are not easily destroyed by heat even at room temperature above 100°C or 212° F. Substances which interfere with or destroy vitamin E in the body are iron compounds, synthetic oestrogen, and chlorine or chlorinated water.

Approximately 50 to 85 per cent of Vitamin E in the diet is absorbed from the gastro-intestinal tract by a mechanism similar to that of other fat-soluble vitamins. It enters the bloodstream via the lymph. The vitamin is stored in all the tissues, and the tissue stores can, provide protection against the deficiency of this vitamin for long periods. About one-third of the vitamin E is excreted in the bile and the balance is excreted in the urine.
