Vitamin B6 Guide: Pyridoxine, P5P, Benefits, Nerve Safety and Where to Buy

Vitamin B6 is a water-soluble B vitamin involved in protein metabolism, nervous system function, red blood cell formation, immune function and hormone-related pathways. Pyridoxine is one common supplemental form of Vitamin B6.
