Vitamins are organic substances with a simple structure in terms of chemistry. The first vitamin discovered by scientists belonged to the class of amines, therefore these substances were given such a name.

Vitamin U was discovered due to its ability to prevent stomach ulcers. This was reflected in his name. It comes from the Latin word ulvus , which means "ulcer".It is also able not only to heal the mucous membrane of the stomach, but also to normalize acidity.
In addition, this substance is used by the body in the synthesis of hormones, such as adrenaline, and also in the production of choline. Another vitamin U is used as a source of the macroelement of sulfur. The latter is needed for the synthesis of many organic substances, including cysteine and collagen. Another important property of this substance is its antihistamine effect. He also participates in the metabolism of fats, preventing their deposition in the liver and other organs.
