Vitamin B6: functions and role in the human body
Pyroxidin, as vitamin B6 is also called, takes part in more than a hundred different biochemical processes in which it plays the role of a coenzyme. To avoid a lack of this vitamin, you need to know which products contain it (the list of products can be found here: http://pitanieinfo.ru/vitaminy/b6 . Among the processes that require the presence of a sufficient amount of vitamin B6, we can highlight:
- glycogen metabolism;
- amino acid metabolism;
- production of nucleic acids;
- production and metabolism of hemoglobin.
Pyroxidine is an integral component of a number of processes occurring in the body. So:
- The processing of carbohydrates and proteins to produce energy is carried out with the participation of vitamin B6.
- Vitamin B6 is also involved in the processing of amino acids, promotes their absorption through the digestive system, as well as synthesis and destruction.
- Pyroxidine helps convert the amino acid tryptophan into niacin (vitamin B3) and serotonin (the neurotransmitter of happiness);
- Pyroxidine is involved in the production and synthesis of numerous body chemicals:
- insulin;
- enzymes;
- hemoglobin;
- neurotransmitters (for example, dopamine);
- prostaglandins;
- histamine;
- adrenaline.
Vitamin B6 ensures the health of the immune system and supports its proper function.
In addition, pyroxidine is necessary for the normal functioning of the brain and central nervous system as a whole, and pyroxidine is also extremely important for the health of neurons and muscle cells.
The production of red and white blood cells (ie, red and white blood cells) is another important mission of vitamin B6, along with the heart protection it provides by fighting cholesterol deposits.
To improve the absorption of vitamin B12 is also necessary vitamin B6.

Based on the above tasks that vitamin B6 performs, you can understand what the lack of this vitamin in the body leads to.
It is worth noting, however, that vitamin B6 deficiency is rare, since almost all foods contain at least a minimal amount of pyroxidine. The most common cause of vitamin B6 deficiency is impaired absorption of nutrients in the digestive system. The reasons for such violations may be:
- alcohol abuse;
- chronic diarrhea;
- some medications (isoniacid, hydrolasine, penicillamine).
A lack of vitamin B6 can also be a consequence of disruption of the normal functioning of the central nervous system (CNS).
