Vitamin B6 can be found in three different forms: pyridoxine, pyridoxamine, and pyridoxal, all of which are normally present in food. Vitamin B6 must first be converted to the active compound pyridoxal-5-phosphate (P5P) in the liver.
This vitamin plays an important role in various functions of the body, such as: metabolism at the cellular level, muscle growth and repair, regulation of mood, regulation of sleep and is very popular among women as a premenstrual supplement.
