B9 in its Most Biologically Active Form

Why should you choose l-methylfolate 1mg, provided as Quatrefolic, as your go-to form of Vitamin B9? This glucosamine salt of 5-MTHF is not only the most bioavailable form of the water-soluble B9 vitamin, folic acid, but Quatrefolic specifically has demonstrated greater stability and solubility, too. With a number of common conditions limiting conversion or absorption of folic acid, choosing a biologically active, plasma folate is crucial.

Our Experts Say

L-methylfolate is the active form of folate and is more easily absorbed and used by the body than other forms of the B9 vitamin. By supplementing with our quick-release L-methylfolate, pregnant women can ensure that they are getting enough of this essential nutrient to support the healthy development of their babies. Non-pregnant people can experience more of the benefits of B9, like healthy cell growth and function, with this bioactive folate too!

Formulated with Quatrefolic for Increased Bioactivity
Quatrefolic is a highly bioavailable form of folate (Vitamin B9) since it’s already in its active form and can be more effectively utilized. More stable and water-soluble, Quatrefolic requires no specific enzymes present to be activated, making it more accessible and effective at reducing homocysteine levels in the body.
Support a Healthy Pregnancy
Supplementing with L-methylfolate during pregnancy can support the healthy development of the fetus. Folate, including L-methylfolate, is critical for proper cell growth and development, particularly in the early stages of pregnancy. Adequate intake of folate can help prevent birth defects in the baby's brain and spine, such as neural tube defects.

How to Use

Daily Use

Take 1 to 2 capsules per day, or as directed by your healthcare provider.
