Among the processes that require a sufficient amount of vitamin B6 , you can highlight:
- glycogen metabolism;
- metabolism of amino acids;
- nucleic acid production;
- hemoglobin production and metabolism.
Pyroxidine – an integral component of a number of processes occurring in the body. So:
- The processing of carbohydrates and proteins for energy production 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 to convert the amino acid tryptophan into niacin (vitamin B3) and serotonin (the happiness neurotransmitter);
- Pyroxidine is involved in the production and synthesis of numerous body chemicals:
- insulin;
- enzymes;
- hemoglobin;
- neurotransmitters (e.g. 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 the central nervous system as a whole, and pyroxidine is extremely important for the health of neurons and muscle cells.
