Nervous System Health Coenzyme B-6 + Mg Bisglycinate Non-GMO A Dietary Supplement Vegetarian / Vegan Kosher Vitamins Family Owned Since 1968 GMP Quality Assured Vitamin B-6 (pyridoxine) acts primarily as an enzyme catalyst in many body processes including energy metabolism and neuro-transmitter function. Before it can be used for this purpose it must be converted into its coenzyme form (P-5-P) by the liver. P-5-P eliminates this step by providing B-6 in its converted form, allowing for greater bioavailability.
