Pyridoxine hydrochloride, also known as vitamin B6, is a water-soluble vitamin that is essential for many physiological processes in the body, including the metabolism of amino acids, the production of neurotransmitters, and the formation of red blood cells.
In protein powders, pyridoxine hydrochloride may be added as an ingredient to help increase the vitamin B6 content of the product. Vitamin B6 is important for individuals who engage in regular exercise, as it can help to support energy metabolism and reduce the risk of exercise-induced fatigue.
Pyridoxine hydrochloride is generally considered safe when used in recommended amounts.
