Vitamin E has been shown to be effective against numerous conditions and diseases that are linked to oxidation. It prevents oxidative stress, protects cell membranes and regulates platelet aggregation. It has also been found to be very effective in the prevention and reversal of various disease complications.
Studies related to the role of vitamin E in human health and some diseases shows that :
- High plasma levels of vitamin E are associated with a reduced risk of AD (Alzheimer’s disease} in older people.
- Its supplementation significantly enhances both cell-mediated and humoral immune functions in humans, especially in the elderly.
- Vitamin E improved the antibody response to various vaccines in healthy subjects
- Vitamin E can enhance the immune response to a specific antigen.
- Viitamin E stimulates the body’s defences and increases phagocytic functions. It also has a pronounced effect in infectious diseases where immune phagocytosis is involved.
- The resulting symptoms of vitamin E deficiency include muscle weakness, vision problems, immune system changes, numbness, difficulty in walking and tremors as well as a poor sense of balance.
- Vitamin E deficiency can cause anaemia, retinopathyand the impairment of the immune response. If untreated, vitamin E deficiency may result in blindness, heart disease, permanent nerve damage and impaired thinking.
Vitamin E has been found to be very effective in the prevention and reversal of various disease complications due to, its anti-inflammatory properties,, its inhibition of platelet aggregation, immune-enhancing activity and its function as an antioxidant.
There are eight naturally occurring forms of vitamin E; namely, the alpha, beta, gamma and delta classes of tocopherol and tocotrienol, which are synthesised by plants from homogentisic acid. Alpha-and gamma-tocopherols are the two major forms of the vitamin, with the relative proportions of these depending on the source.
The richest dietary sources of vitamin E are edible vegetable oils as they contain all the different homologues in varying proportions
Vitamin E deficiency is quite rare in humans. It happens almost exclusively in people with an inherited or acquired condition that impairs their ability to absorb the vitamin and in those who cannot absorb dietary fat or have rare disorders of fat metabolism.
