* (6S)-5-Methyltetrahydrofolic Acid Glucosamine Salt * 4th Generation Folic Acid Technology * The More Stable, More Bioavailable Form of Folate * Quatrefolic * Dietary Supplement * Vegan Methyl Folate ((6S)-5-methyltetrahydrofolic acid or (6S)-5-MTHF) is the most biologically active form of folic acid. Quatrefolic is the 4th generation development in folate delivery. With certain inherited errors in metabolism and under a variety of physiologic stresses, the transformation of folic acid into the active form of folate either does not properly take place or is inadequate. Unlike folic acid, this form of folate can cross the blood-brain barrier. Methyl Folate is needed to support cardiovascular and neurologic health and proper cell division. Health Claim: Healthful diets with adequate folic acid may reduce a woman"s risk of having a child with certain brain or spinal cord defects.
