Vitamin E (tocopherol) - a fat-soluble antioxidant, resistant to acids, alkalis and high temperatures. Healthy people practically do not lose vitamin E in urine and faeces: the kidneys and intestines, he does not stand out. However, it disappears from the tissue when a person is too long stay in the sun. It should not be abused, even tan because of the beauty of the skin - it can turn into a disaster for health.
What is the
Vitamin E is not toxic, but its content is excessive increase in blood pressure. For gipotonikov this may be the way of treatment, and for hypertensive patients should refrain from taking large doses and limit natural products in which this vitamin is incorporated in the required quantities and the right combinations.
Vitamin E called "fertility vitamin". This means that it provides the gonadal sex for both women and men. If any violations in the endocrine system (and therefore also in the nervous system, brain, blood vessels) must pay attention to the level of vitamin E in the body.
In addition to the sexual glands, vitamin E ensures the functioning of the heart muscle. It is also effective in the treatment of diabetes and asthma, prevents the formation of clots in blood vessels, cleaning veins, arteries, capillaries of blood clots. That's why patients usually thrombosis and thrombophlebitis, doctors recommend taking vitamins K and A.
Vitamin E also helps to reduce the symptoms of premenstrual syndrome, is effective in the treatment of eye diseases such as cataracts, and neurological diseases such as Alzheimer's disease, and diabetes
Diabetes - threatening and incurable disease
.
Vitamin E - one of the most powerful of our allies in protecting the body from damage caused by free radicals - unstable compounds that destroy the cell structure. Moreover, tocopherol is essential for normal functioning of the immune system, it lowers the blood cholesterol level and reduces the risk of cancer.
Scientists have discovered that if the way of an obstruction of blood flow (blood clot), then vitamin E may help to form a number of the new blood vessel.
Tocopherol - a powerful antioxidant vitamin and circulating with the blood and neutralize free radicals, harmful metabolic waste to prevent damage to cell membranes, and thereby reducing the risk of heart disease and cancer.
Furthermore, in the human vitamin E:
- takes part in protein metabolism;
- involved in the synthesis of heme - a main component of hemoglobin;
- It lowers the level of glucose
Glucose: The energy source
;
- normalizes blood clotting and improves circulation;
- increases immunity;
- reduces the severity of diabetic complications;
- It helps to reduce weight;
- normalizes muscle activity;
- promotes normal pregnancy and fetal development;
- speeds healing and reduces the likelihood of scarring;
- facilitates Parkinson's disease and Alzheimer's disease;
- treats skin diseases;
- It helps to restore collagen and elastic fibers of the skin, preventing the appearance of wrinkles.
The main dietary sources of vitamin E are:
- whole grain cereals,
- vegetable oils,
- eggs,
- lettuce,
- chestnuts,
- liver
- nettle leaves,
- mint

- carrot tops, celery,
- asparagus,
- broccoli,
- bran.
Vitamin E should be used in combination with vitamins A and C (butter, cream, egg yolk, sour milk, and vegetables - potatoes, cabbage, lettuce, carrots, green parts of plants). Earlier usually recommended for adults only 10-20 mg and for children 0, 5 mg per 1 kg of body weight, but lately doctors recommend increasing the daily rate of vitamin E and 600 mg.
The recommended daily intake of
Antioxidants protect the cells of living tissues from the damaging effects of free radicals - molecules with an unpaired electron. Free radicals destroy cells may contribute to the development of cardiovascular disease and cancer. Unpaired electrons are very active and quickly react with oxygen to form reactive oxygen species (ROS). These compounds are part of the mechanism of signal transduction between cells. The body forms of ROS in the process of converting food into energy, but antioxidants should protect cells from exposure to them. Furthermore, the free radicals formed as a result of external factors, such as tobacco smoke, air pollution, UV radiation.
Vitamin E is a fat-soluble antioxidant that blocks the production of reactive oxygen species formed when fat is in the process of oxidation. Scientists are not the first decade of conducting research, trying to understand whether vitamin E, limiting the production of free radicals and possibly affecting some of the other processes, prevent or at least slow down the development of chronic diseases that are associated with exposure to these extremely active molecules.
Vitamin E is an antioxidant not only
Antioxidants: the truth about the notorious benefits
; it also improves the functioning of the immune system and, as shown by laboratory experiments, stimulates signaling between cells, regulates gene expression and various metabolic processes. Alpha-tocopherol inhibits the activity of protein kinase C, an enzyme that can cause proliferation of smooth muscle cells, platelets and monocytes. Because vitamin E endothelial cells covering the inner surface of blood vessels, to better withstand the formation of various deposits on the walls of blood vessels. Vitamin E improves the expression of two enzymes, which inhibit the metabolism of arachidonic acid. Due to the endothelium releases more prostacyclin, which in turn expands the blood vessels and inhibits platelet aggregation.
For all the vitamins and minerals have their own rules of consumption that determined the experts, and the violation of which can be dangerous to health. The rate may be different, depending on the sex and age of the person, but in any case it is focused on the healthy members of a certain group of people. If you have any diseases (especially chronic) to determine the rate of consumption must physician.
The recommended daily intake (CFSTR, on the labels of food and vitamin supplements are often referred to as the RDA) - is the average daily consumption of substances necessary majority (97-98%) healthy individuals.
Adequate intake of (ANP) is established when there is insufficient data to determine CFSTR. We can say that this rate of consumption of substances, which is currently considered adequate, although the required amount thereof is not established.
Tolerable upper intake level (VDUP) - maximum tolerable daily intake of a substance that, in most cases, does not cause unwanted effects. Exceeding this dose may be hazardous to health.
The following recommended daily intake of vitamin E apply only alpha-tocopherol.
They were identified as a result of experiments that measure the amount of vitamin E in the blood necessary for the survival of red blood cells when exposed to hydrogen peroxide - free radical. Scientists recognize that the results of these experiments raise some doubts, and now new research conducted to identify the biological markers that would help to define more precisely the rate of consumption of vitamin E. Because of the lack of data for newborns was established only until an adequate intake of .
The table below intakes of vitamin E are indicated in milligrams, and in international units (IU). The latter are defined rather level of biological activity than the amount of material and many of today's packaging vitamin supplements the amount of active substances contained therein is indicated in IU (IU or - by international units).
Vitamin E contained in natural sources (dietary), called D-alpha-tocopherol. The synthetic form of Vitamin E is known as DL-alpha-tocopherol.
1 mg alpha-tocopherol equals 1.49 IU of D-alpha-tocopherol, and 2.22 IU synthetic alpha-tocopherol.
1 IU of alpha-tocopherol equals 0.67 mg D-alpha-tocopherol and 0.45 mg DL-alpha-tocopherol.
The table shows CFSTR and ANP for natural alpha-tocopherol; to find out the recommended norm of its synthetic form, multiply the daily rate specified in milligrams, at 2.22.
