It plays an important role in many biochemical processes in the human body, such as amino acid metabolism, hemoglobin synthesis, the functioning of the nervous system, immune system and others. In this article we will look at the main functions of vitamin B6, indications for its use and contraindications.

Functions of vitamin B6 in the body

Vitamin B6 is a cofactor for many enzymes involved in amino acid metabolism. It is also necessary for the synthesis of certain neurotransmitters such as serotonin, norepinephrine and dopamine, which regulate mood and behavior. Vitamin B6 also plays an important role in the synthesis of hemoglobin, the protein that transports oxygen in the blood.

Vitamin B6 is used to treat various diseases and conditions, such as:

1. B6-hypovitaminosis (vitamin B6 deficiency)
2. Toxicosis of pregnant women
3. Sideroblastic anemia

conclusions

Vitamin B6 plays an important role in many biochemical processes in the human body. It is used to treat various diseases and conditions such as B6 hypovitaminosis, toxicosis of pregnancy, anemia and diseases of the nervous system. However, vitamin B6 has contraindications and may cause side effects, so it should be used only as prescribed by a doctor and in accordance with the recommended dosage.
