Vitamin PP


The history of the vitamin: Nicotinic acid has been known for a long time: back in 1866, it was obtained by the German chemist Hubert by oxidizing nicotine isolated from tobacco. But until the 40s of our century, no one suspected that nicotinic acid has a vitamin effect. HER was recognized as a vitamin after it turned out that she perfectly cures pellagra, a serious disease from which thousands of people who ate mainly corn suffered. Vitamin PP got its name from the initial letters of the English words «pellagra preventing» — «warning pellagra». Why is it needed? Niacin is part of the enzymes involved in providing the body with energy through the oxidation of carbohydrates and fats. It is necessary for the secretion of salic acid in the stomach and the normal functioning of the digestive system. Niacin also helps to eliminate toxins from the body, improves blood circulation in small vessels, including the vessels of the placenta — during pregnancy. Niacin is involved in the regulation of the function of the thyroid gland and adrenal glands — endocrine glands, in case of violation of which there is a threat of abortion. It is important for the growth of the body, including the body of the fetus during fetal development. Preparations containing niacin are used in the treatment of anxiety, and this condition is known to often occur during pregnancy.
