Vitamin B6, the so-called pyridoxine is a water-soluble vitamin necessary for the proper functioning of the body. After ingestion, it is absorbed from the digestive tract and stored mainly in the muscles and liver. It is part of approximately 50 enzymes that actively participate in various biological processes of the body. Vitamin B6 participates in the transformation of proteins, carbohydrates and fats. It also takes part in the transformation of amino acids and is necessary to convert tryptophan into niacin, the so-called vitamin PP. It is also necessary for the synthesis of hormones, such as serotonin and adrenaline, which affect the proper functioning of the nervous system.

Furthermore, pyridoxine has an effect on muscle spasms, blood pressure and heart function. It participates in the formation of antibodies, so it increases the body’s resistance.

Another important function of this vitamin is its participation in the processes occurring in the muscles such as: glycogenesis – transformation of glucose into glycogen and glycogenolysis – the process of glycogen metabolism. Vitamin B6 is also essential in the production of hemoglobin.
