Without the necessary amount of vitamins A and E, serious malfunctions occur in the functioning of our body. And, actually, why do vitamin A and E?
Retinol (vitamin A) is a fat-soluble vitamin,antioxidant, without which the normal functioning of the immune system is impossible, the condition of the hair, skin, bones, and vision is deteriorating. Retinol takes part in the regulation of protein synthesis, in the oxidation-reduction process, promotes the function of subcellular and cellular membranes, normalizes the metabolism. Without vitamin A, the normal formation of teeth, bones and fat deposits is impossible. Retinol stimulates the growth of new cells, slows down aging.
Vitamin A is dissolved by fat, hence itsassimilation by the food tract also requires the presence of fats, and also of minerals. The reserves of retinol in the body are preserved for a long time, so the daily replenishment is not required. Vitamin A has two forms: actually vitamin A and provitamin A, which turns into a vitamin already in our body. Provitamin A is a plant form of retinol. Opened vitamin A one of the first, it happened in 1920. Vitamin A is rich in products such as fish liver and fat, butter, egg yolks, whole milk and cream. Cereals and skim milk for vitamin A are not rich even with artificial addition. The daily dose of retinol is, for men: 900 μg (3000 IU), for women: 700 μg (2300 IU). In diseases caused by vitamin A deficiency, the daily dosage is increased to 10,000 IU.
They discovered vitamin E in 1922. Under the definition of "vitamin E", we now know 4 compounds of tocopherol, as well as 4 - tocotrienol. Since alpha-tocopherol has the highest biological activity and is most common, vitamin E is often called tocopherol or alpha-tocopherol. Vitamin E is fat-soluble, indifferent to high temperatures, but does not tolerate light.
The second name of tocopherol is the vitamin of "youth andfertility ". As a powerful antioxidant vitamin E helps slow the aging process, ensures the functioning of the gonads, both in men and women. In addition, vitamin E provides normal functioning of the immune system, activates cell nutrition, strengthens the walls of blood vessels, promotes peripheral circulation, prevents thrombosis. Thanks to tocopherol, blood coagulability is normalized, muscles are maintained, nerve health is maintained, diabetes and Alzheimer's disease are alleviated, anemia is prevented.
Vitamin E protects against oxygen damageother fat-soluble vitamins, improves the absorption of vitamin A, promotes the formation of collagen fibers in the intercellular substance, prevents the development of senile pigmentation. Vitamin E is an excellent preventive tool for cardiovascular and cancer. The daily dose of tocopherol for children younger than 1 year is 0.5 mg / kg of weight, for adults - 0.3 mg / kg. For pregnant women and nursing mothers, as well as under high loads for athletes, it is recommended to increase the dose.
