Vitamin B6, also known as pyridoxine, is a water-soluble vitamin that can be found in many foods naturally as well as in food and supplements. The active coenzyme form, pyridoxal 5' phosphate (PLP), is the most used marker of B6 blood levels in the body.

Pyridoxine (Vitamin B6) is a co-enzyme for several enzyme systems involved in the metabolism of proteins, carbohydrates, and fats. Long-term use of large doses of vitamin B6 can, however, cause complications in the peripheral nervous system.

The standard B6 supplement is pyridoxine hydrochloride (HCL). Pyridoxine requires conversion in the liver to its active co-enzyme form called pyridoxine-5-phosphate (P5P) in order to become involved in processes. Is important for the utilisation of key nutrients such as B Vitamins and assimilation of dietary protein, metabolism of proteins, lipids, and glucose. P5P is now know to be the main circulating form of B6 exported from the liver and is considered the most relevant direct measure of vitamin B6 status.
