The role of vitamin E in the body
Tocopherol (vitamin E) is a fat soluble substance. In the body, it is not produced. It enters into it with food of both animal and vegetable origin. A necessary condition for its assimilation is the intake of sufficient amount of fats.
In the body, its functions are:
- protection of cells from the effects of aggressive free radicals (it is an antioxidant);
- to promote the assimilation of vitamin A;
- acceleration of the cholesterol splitting process , prevention of the formation of cholesterol plaques in the vessels;
- participation in the synthesis of certain proteins, hormones, and hemoglobin, without which it is impossible to supply cells with oxygen;
- counteract the formation of blood clots in blood vessels, reduce blood clotting.
Small children, pregnant and lactating women, as well as elderly people, often receive synthetic tocopherol. For children and adolescents, vitamin E is essential for the normal development of organs. In the first weeks of pregnancy, it is taken to improve the blood supply to the fetus and the formation of the placenta.

As the development and growth of the need for a sufficient amount of this substance in children is constantly increasing. It reaches a maximum at the time of puberty. At this time, the organs of the reproductive system begin to function, there is a need for increased blood supply, an increase in the production of hormones.

Warning: With prolonged treatment with vitamin E preparations, it is necessary to regularly give blood for biochemical analysis to check the glucose, urea, cholesterol, bilirubin and other substances. This allows you to monitor the liver, kidneys, blood vessels and other organs.
The consequence of excessive accumulation of tocopherol can be a disorder of reproductive function, kidney damage, the appearance of intestinal and uterine bleeding. The dangerous consequences of an overdose of tocopherol are myocardial infarction, blockage of blood vessels by a severed thrombus (thromboembolism), as well as disruption of the central nervous system.
Vitamin E lowers the ability of the body to absorb vitamins D and A, so overdose leads to increased fragility of bones due to a lack of calcium.

The causes of the appearance of an excess of tocopherol
An overdose of vitamin E can occur if, under normal nutrition and the use of a sufficient number of products containing it, a person additionally takes tocopherol in the form of preparations. And this happens for a long time, and the dose considerably exceeds the daily requirement.
The risk is increased in patients to whom vitamin E is prescribed most often:
- patients with hypertension (to improve the state of blood vessels);
- diabetes mellitus ( to eliminate beriberi );
- with diseases of the heart (in order to strengthen the vessels and the heart muscle);
- disorders in the thyroid gland.
The occurrence of an excess of tocopherol is facilitated by a shortage in the body of vitamin K.
People who have similar health problems should take vitamins with great care, starting with minimal doses. When prescribing drugs, the possibility of an allergic reaction to this substance is taken into account.
Tablets of tocopherol can not be consumed by people taking anticoagulants (for example, iron preparations or aspirin), antibiotics, as well as drugs that regulate blood pressure. With great care should take tocopherol smokers, because the simultaneous accumulation of nicotine and vitamin E in the body leads to a stroke.
Diagnosis and treatment of overdose
In case of symptoms of vitamin E overdose, it is important to consult a doctor and hand blood and urine for analysis. An increase in cholesterol, a decrease in thyroxine content, and characteristic changes in other parameters will lead to the conclusion that it is necessary to correct the content of tocopherol in the body. This state is also indicated by a decrease in the level of sex hormones in the blood.
When an overdose of tocopherol in the body, first of all, the intake of its synthetic drugs stops, a special diet with restriction of the use of certain foods is prescribed. In the case of a significant excess of the norm, intravenous injection of plasma-substituting (physiological) solutions is prescribed for the removal of intoxication, replenishment of the salt balance in the body.
There are also means for lowering blood pressure and improving liver function.
