What you need to know about Vitamin E
Vitamin E is a fat-soluble substance that is one of the essential nutrients for the development and health of the body. It brings together eight substances (vitamin E compounds) including:
- 4 tocopherols: alpha-tocopherol, beta-tocopherol, gamma-tocopherol, delta-tocopherol;
Among them, the form most useful to the body is alpha-tocopherol . It is particularly recognized for its antioxidant function as well as its actions to fight against oxidative stress and cellular aging. It also promotes the action of vitamins A and C. In everyday life, vitamin E is used as a food preservative . It is usually seen under the names of E306, E307, E308 and E309.
Vitamin E appears as an oily, pale yellow liquid . It is stored in fatty tissue and muscle. The contribution of this element is done especially by the consumption of food (oleaginous) and vegetable oils which contain it in great proportion. Sometimes, it is possible to find it with other names such as tocopherol or factor X (old name).
Vitamin E: an element with multiple benefits
The health and wellness benefits of vitamin E are many and varied.
Vitamin E acts as a natural antioxidant
The antioxidant capacity of vitamin E is one of the properties that make it occupy an indispensable place in the body. It neutralizes excess free radicals and inhibits their adverse effects on the body:
- accelerated aging of cells and especially of the skin;
- aging and deterioration of organs;
- oxidation and then accumulation of bad LDL cholesterol in the blood vessels;
- development of pathologies such as inflammations and cancers…
Reduces the risk of developing cardiovascular diseases
At the level of the cardiovascular system, vitamin E plays various important roles. Thanks to its anti-inflammatory action and its ability to retain membrane lipids, tocopherol helps maintain good blood circulation. It prevents the formation of blood clots and atherosclerotic plaque (lipids) inside the blood vessels.
This vitamin also prevents many cardiovascular problems like atherosclerosis. The latter is often the cause of cardiovascular accidents.
Warning ! it should be noted that the reduction in the risk of developing cardiovascular diseases mentioned here is properly induced by the sufficient dietary intake of vitamin E. The use of supplementation, on the other hand, represents a rather dangerous practice, especially in the long term. A large number of recent studies on the subject have attested to the fact that it exposes to a high risk of stroke.
Vitamin E protects against AMD and neurodegenerative diseases
Already widely used in the medical field, vitamin E is now regularly prescribed for the treatment of AMD (age-related macular degeneration) alongside other antioxidants. They slow the progression of the disease. It also prevents certain types of cognitive disorders and neurodegenerative diseases, namely Alzheimer’s, Parkinson’s disease, etc.
Maintains healthy skin
Being a constituent of cell membranes, vitamin E ensures the tone and firmness of the skin. In addition, through its antioxidant effect, it fights against skin aging and the appearance of wrinkles. During an injury, vitamin E intervenes by stimulating the healing process. It also limits the appearance of unsightly scars.
Vitamin E deficiency: a rare but very dangerous disease
Although vitamin E is necessary for the body, you should know that the latter is unable to synthesize it itself. To cover one’s daily needs, one must stock up with a balanced diet. Vitamin E deficiency is a fairly exceptional case, especially in adults. The people most at risk are young children and premature babies.
The probable causes of vitamin E deficiency are:
- a disorder within lipid metabolism;
- an assimilation problem: generally associated with a digestive disease;
- a lack of absorption in the liver.
Vitamin E deficiency is manifested by various disorders: muscular and nervous disorders, motor disorders and in children, hemolytic anemia… It also leads to cardiovascular and coronary diseases.
