Video: ❶ What Are Vitamins For
For the normal course of all biochemical and physiological processes, a daily intake of vitamins is necessary. And, despite the fact that the body requires only a hundredth of a milligram, it is often deficient in them. And this condition does not go unnoticed for health. Location: Location: Vitamins are necessary for normal metabolism, growth and renewal of cells and tissues, as well as for the absorption of all useful components from food. With their participation, the formation of enzymes, hormones, as well as the activation of minerals that are present in the body mainly in sufficient quantities.
Water-soluble vitamins - C and group B - are not able to accumulate and store in the body for future use. Therefore, he needs them constantly. Being present in the enzyme systems of the body, they participate in the digestive process, as well as in the formation of biochemical substances and energy.
Vitamin C or ascorbic acid is the main component of the redox processes of the cell. With its participation, amino acids and collagen are formed. This vitamin improves immunity, is responsible for the good condition of the walls of blood vessels and gums.
B vitamins have a great effect on metabolism, blood formation, the functioning of the nervous system, the condition of the skin, hair and nails, as well as the digestion process. A special role belongs to vitamins B6, B9 (folic acid) and B12.
Fat-soluble vitamins A, E, D, K are able to create a reserve in the body. They are essential for immunity, enzyme and hormone production, bone strength, and as antioxidants. The accumulation sites for these vitamins are the liver and adipose tissue. Due to their slow elimination from the body, additional or prolonged intake of them can easily cause oversaturation and toxic poisoning. Therefore, even prophylactic doses of these vitamins should be courses.
Vitamin A is essential for vision, preservation of reproductive function, growth and development of bones, enhancement of immunity, beauty of skin, hair and nails.
Vitamin E is an antioxidant. Just like vitamin C, it regulates the redox processes in the cell. Prevents oxidation of polyunsaturated fatty acids, improves the functioning of the cardiovascular system and prevents spontaneous miscarriages in pregnant women.
Vitamin D is an important regulator of mineral metabolism and promotes the absorption of calcium and phosphorus. It is essential for the preservation of teeth and bones.
Vitamin K ensures normal blood clotting, participates in the metabolism of bones and connective tissue, and also supports normal kidney function.
Vitamin deficiency entails changes in the body's enzyme systems, hormonal disorders and many other pathological processes. Often, hypovitaminosis and vitamin deficiency pass under the guise of other diseases, in the treatment of which vitamin therapy is not always used. As a result, their cure is often difficult to achieve.
In addition to the intake of vitamins with food, it is necessary to take care of their periodic intake in the form of preparations, since food does not always contain the required amount. Moreover, their consumption can significantly exceed the income. This often occurs during pregnancy and lactation, during any illness, during menopause, with increased physical activity, as well as during intensive development and growth (in infants and adolescence).
