The essentiality of vitamin E for humans was recognized in the late 1960s in connection with studies on premature infants in which hemolytic anemia was associated with vitamin E deficiency.
Vitamin E is considered to be most effective antioxidant more effective, for example, than beta carotene at relatively higher oxygen partial pressure, and is more selectively distributed to the nuclear fraction as compared with other sub-cellular fractions.
The fact that that high dosage of vitamin E is not toxic, therefore many research is focused on anti-cancerous properties of vitamin E.
The later study being made is the relation of vitamin E to the new growth, or division, of cells necessary to keep the tissues in healthy repair.
In one study, when cancer tissue was placed in a vitamin-E-rich blood serum, the cancer tissue did not grow. When a blood serum lacking vitamin E as used in a similar test, the cancer cells divide normally in the presence of vitamin E.
Many studies have also found that high levels of vitamin E in the body are associated with a lower risk of cancer, whereas low level are associated with a greater risk.
These trends have been indentified with breast cancer, cervical cancer and cervical dysplasia, colon cancer, lung cancer, and throat cancer.
