BioCoenzymated™ Pyridoxal 5'-phosphate from Natural Factors delivers a potent 50 mg of vitamin B6 per serving. Coenzymated vitamins are those that have been pre-converted into their most metabolically active forms, meaning you get a greater benefit from a smaller dose. Natural Factors takes this effect one step further with their proprietary "EnviroSimplex®" technology which features the inclusion of plant extracts for optimum absorption.
