Jarrow Formulas Methyl Folate features (6S)-5-Methyltetrahydrofolate Glucosamine Salt, the 4th Generation Folic Acid Technology, offering a more stable and bioavailable form of folate. This supplement is Non-GMO Certified by NSF™, Gluten-Free, and provides a highly bioactive form of folate known as Quatrefolic®. Methyl Folate ((6S)-5-methyltetrahydrofolate or (6S)-5-MTHF) is preferred over synthetic folic acid due to the body's limited ability to convert the latter into the active folate form. Each bottle contains 60 veggie capsules, with 400 mcg of Methyl Folate per serving. It supports energy levels and is a dietary supplement.
