vitamins of the group in To be healthy, you need to eat morevitamins - even small children know this. But what exactly are vitamins? To this question, perhaps, not everyone will answer. Vitamins are substances, small amounts of which are necessary for the body for its normal life. They take part in many of the most complex processes that occur in our body. Some vitamins can be "produced" by the body itself, but the overwhelming majority of them are either produced in insufficient quantities, or - as a rule - completely must come from outside, with food or in the form of medicines. Everyone knows that vitamins are called letters of the Latin alphabet. There is, for example, vitamin C, vitamin K or, vitamin A. But why among these vitamins stands out a whole "team" of vitamins B? The fact is that their discoverer, the Polish scientist Kazimir Funk, was convinced that vitamin B is one substance. And only later the researchers revealed a whole group of nitrogenous compounds (that is, containing nitrogen in their molecules) compounds. At different times, up to twenty B vitamins were isolated, starting with vitamin B1 and ending with vitamin B20. Now it is considered that only nine substances belong to this group: Vitamin B1 (thiamin, aneurine):

  • participates in carbohydrate and amino acid metabolism;
  • strengthens the nervous, immune muscle systems;
  • improves the functioning of the stomach, intestines and liver;
  • reduces the likelihood of vascular and heart disease.

Thiamine produces bacteria that live inintestines. However, this amount is not enough, so vitamin B1 should additionally enter the body with food. Contained in cereals, bran, legumes, sprouted grains, rosehips, nuts, cabbage, potatoes, milk, eggs, pork, veal. Vitamin B2 (riboflavin) - is considered one of the most important for human vitamins. The lack of it affects the condition of nails, hair, skin:

  • participates in a variety of biochemical reactions;
  • improves the restoration of damaged tissues;
  • protects the retina from the adverse effects of sunlight.

Contained in yeast, dog rose, beans,cabbage, tomatoes, spinach, milk, eggs, liver, apricots, and also in leafy vegetables of dark green color. Unlike most B vitamins, riboflavin is fairly resistant to high temperatures. Vitamin B3 (nicotinic acid, niacin, vitamin PP):

  • participates in the breakdown of fats and sugars;
  • Favorably affects the vessels, heart, liver, pancreas;
  • reduces the content of cholesterol and triglycerides in the blood;
  • prevents the formation of blood clots;
  • improves the activity of the nervous system;
  • increases the production of gastric juice;
  • participates in the formation of hormones (insulin, cortisone, thyroxine, estrogen, progesterone, testosterone).

It is found in white chicken meat, liver, kidneys, cheese, eggs, fish, tomatoes, mushrooms, green peas, peanuts, potatoes, beans, brewer's yeast and some herbs. Vitamin B4 (choline):

  • prevents the breakdown of the nervous system;
  • prevents the formation of gallstones;
  • prevents vascular and heart disease, normalizes the rhythm of the heart, strengthens the myocardium (heart muscle);
  • participates in the breakdown of fat and lowers the cholesterol in the blood;
  • regulates the level of sugars in the blood;
  • supports the work of the prostate gland in the elderly;
  • improves mental abilities.

The main source of choline is the egg yolk. It is also found in the liver, cheese, cottage cheese, soy, peanuts, some vegetables. Can be synthesized in the body. Vitamin B5 (pantothenic acid) - is part of coenzyme A, an indispensable participant in many biochemical processes:

  • a strong stimulant of adrenal function - so this vitamin is often prescribed for the treatment of arthritis, heart and vascular disease, as well as allergies;
  • inhibits the formation of cholesterol;
  • accelerates the breakdown of fats.

It is found in almost any foodstuff(which is why vitamin B5 is called pantothenic acid - from the Greek word pantoten - everywhere). Lack of pantothenic acid is possible only if there is a violation of its absorption in the intestine (bowel disease, stress, prolonged treatment with antibiotics). Vitamin B6 (pyridoxine):

  • strengthens the immune system;
  • participates in the process of hematopoiesis;
  • regulates blood pressure;

  • takes part in carbohydrate metabolism, regulates the amount of sugars in the blood;
  • enhances fat burning;
  • contains sulfur, necessary for the health of the skin, nails and hair (that is why biotin is sometimes called a vitamin of beauty);
  • is necessary for trouble-free operation of the nervous system;
  • improves the vital activity of useful intestinal microflora.

It is found in almost all products. The maximum amount in eggs, nuts, soy, liver, yeast, milk, red beets, ceps, strawberry and blueberry leaves. In a small amount can be synthesized by the body. It is worth noting that alcohol and antibiotics interfere with the assimilation of B vitamins. This applies especially to biotin. Vitamin B9 (folic acid, vitamin B-c):

  • participates in the processes of hematopoiesis, the formation of erythrocytes, the synthesis of hemoglobin;
  • prevents atherosclerosis;
  • lowers cholesterol in the blood;
  • regulates the work of the nervous system, prevents the emergence of stressful conditions;
  • strengthens the formation of hydrochloric acid in the stomach, improves appetite;
  • plays a huge role for the normal coursePregnancy: reduces the likelihood of miscarriage, premature birth, reduces the risk of postpartum bleeding. Participates in the formation of the organs of the future baby.

This vitamin is found in cabbage, beans,spinach, green onions, carrots, beets, tomatoes, coarse flour, brewer's yeast, egg yolk, cheese, caviar, cottage cheese, liver. It is synthesized by normal intestinal microflora. Quickly destroyed when heated. Vitamin B12 (cyanocobalamin):

  • takes part in cell division;
  • affects immunity and hematopoiesis;
  • participates in the work of the nervous system;
  • participates in the formation of skin cells, the epithelium (inner shell) of the intestine, as well as the myelin sheath of nerves;
  • is necessary for normal liver function;
  • improves the digestive system;
  • together with folic acid is involved incarbohydrate and fat metabolism, in the process of formation of blood cells. Both these vitamins are necessary for the synthesis of nucleic acids necessary for the transfer of genetic information.

Unlike other B vitamins,plant food is not contained. The source of cyanocobalamin are meat products, primarily the heart, kidneys, liver. Contained also in fish, milk, egg yolk, cheese, seafood. Group vitamins in tablets

Together better than apart

Despite the fact that each of these vitaminshas for the organism its special significance, they are all absolutely necessary for the normal functioning of the immune and nervous systems, the growth of the organism and are important participants in the energy exchange. It is noticed that together these vitamins are faster coping with the problems of the body than singly. If we eat incorrectly - a deficiency is found, again, in all the vitamins immediately. Therefore, they are appointed more often than not individually, but by a whole complex. The stock of B vitamins in the body must be replenished daily - after all, these substances are easily soluble in water, which means that they are quickly eliminated from the body. When the deficiencies of these vitamins quite quickly manifest symptoms of avitaminosis B:

  • depression;
  • fatigue;
  • muscle weakness;

In order to avoid these troubles, many complex preparations and bioadditives are created, with some vitamins of group B, and sometimes even with their complete "set".
