Jarrow Formulas Hyaluronic Acid provides the fluid matrix for joint lubrication, skin hydration, and skin repair. Jarrow Formulas Hyaluronic Acid is a low-molecular-weight preparation derived from biological fermentation. It is clinically documented to be bioavailable and to improve hydration of the skin.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, 5-MTHF can cross the blood-brain barrier.
