Despite the fact that the name of nicotinic acid in most people is associated with cigarettes, to them it has nothing to do.

Common names of nicotinic acid:

  • niacin;
  • vitamin PP;
  • vitamin B3.

The name of the substance in Latin is Acidum nicotinicum. The chemical name is 3-Pyridinecarboxylic acid. The formula is C6H5NO3.

Nicotinic acid, according to the medical classification, is a low-molecular organic compound (vitamin) that is necessary for the human body not less than, vitamin C, tocopherol, retinol, cyanocobalamin, etc. Niacin affects the stability of the functions of the central and autonomic nervous systems. Activates the work of the hematopoietic system, the gastrointestinal tract, promotes the stabilization of the hormonal background.

Nicotinic acid stimulates the production of enzymes involved in the cleavage of lipids and carbohydrates. Lack of niacin leads to excessive consumption of sweet and flour dishes.

Stocks of nicotinic acid can be replenished from natural sources - vegetables (potatoes - medium baked potato with peel includes 3.3 mg of niacin, skinless to 2.2 mg, green peas, cabbage (broccoli, leaf, savoy), mushrooms, peppers, tomatoes), buckwheat , wild rice, peanut nuts, brewer's yeast, meat, offal (pork and beef liver), etc. Of the meat and legume products, nicotinic acid is easier to digest than from cereals. This vitamin can be synthesized by the body from tryptophan contained in curds and eggs.

In order to replenish the supply of vitamin PP, it is better to use non-food sources.

Penetrating into the systemic circulation, vitamin B3 enters the brain. Neurons respond to niacin with serotonin production. This neurotransmitter (the hormone of "joy") provides a good mood for a person. Scientifically proven that during the depressive states the production of serotonin is minimized. The level of the hormone "happiness" depends directly on the food ration. When there is a shortage of serotonin, a person needs more calories (biscuits, cakes, cakes, etc.) and foods that contain a lot of glucose (chocolate, candy, etc.). The body seeks to activate hormone production through additional consumption of foods containing an increased amount of carbohydrates. Reception of nicotinic acid automatically reduces the need for carbohydrate food, contributes to easier adaptation to a strict diet.
