L-5-MTHF provides 500 mcg (850 mcg DFE) of natural, biologically active folate. Folate is essential for cell division and growth and for proper homocysteine metabolism.** This formula provides folate in the bioidentical, bioactive form, 5-methyltetrahydrofolate (L-5-MTHF). L-5-MTHF (the “L” signifying that it is the all-natural [6S] isomer) is the active circulating form of folate found in the body and one of the several forms found in food. In nature, it is found only as this [6S] isomer, which is why Designs for Health uses L-5-MTHF (as Quatrefolic®), the natural isomer, rather than the mixed (or racemic) form. This innovative form of folate has demonstrated high bioavailability and solubility as well as long-lasting stability. Quatrefolic® L-5-MTHF is superior to folic acid for helping maintain optimal serum folate.*

Recommended Use: Take one capsule per day or as directed by your health care practitioner.
