BioCoenzymated™ Methylfolate + B12 from Natural Factors delivers a potent 1,000 mcg of folate and 50 mcg of vitamin B12 in a convenient quick-melt tablet. 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.
