Metabolically Active FolateSuperior BioavailabilityQuatrefolic®A Dietary SupplementVegetarian/VeganNon-GMOHow It Works: Folate consumed in the diet or from supplements must be converted to its active form 5-Methyltetrahydrofolate (5-MTHF) to be used by the body. This is a multi-step biochemical process that in some circumstances may not be efficient enough to meet the body's needs. In addition unlike folic acid 5-MTHF can penetrate the blood-brain barrier. This product utilizes a patented form of 5-MTHF with superior bioavailability.
