🧪 Formulation Notes

5-MTHF, provided as Quatrefolic, is the most biologically active form of the water-soluble B vitamin, folic acid. It is the preferred form of folate supplementation due to an array of conditions that can limit conversion or absorption of folic acid. Data indicate that supplementing with 5-MTHF increases plasma folate more effectively than folic acid.

Does not contain: Wheat, gluten, corn, yeast, soy, animal or dairy products, fish, shellfish, peanuts, tree nuts, egg, ingredients derived from genetically modified organisms (GMOs), artificial colors, artificial sweeteners, or artificial preservatives.

Bioactive folate as Quatrefolic

Manufactured in a GMP compliant facility.
