Get your daily dose of natural, biologically active folate with L-5-MTHF! This essential nutrient is crucial for cell division, growth, and balancing the homocysteine pathway.

Our formula provides folate in the bioidentical, bioactive form, 5-methyltetrahydrofolate, known as the “L” isomer – the active circulating form of folate found in the body. Unlike other forms, L-5-MTHF is the natural isomer, found only as [6S] isomer, which is why Designs for Health uses it instead of the mixed (or racemic) form.

To ensure maximum bioavailability, solubility, and long-lasting stability, our product features the patented folate derivative, Quatrefolic®. Studies have shown that Quatrefolic® L-5-MTHF increases blood folate levels much better than folic acid, ensuring that your body gets the most out of this vital nutrient. ? #L5MTHF #NaturalFolate #EssentialNutrient

L-5-MTHF provides a natural, biologically active form of folate. Folate is essential for cell division and growth, and also works to balance the homocysteine pathway.** These formulas provide folate in the bioidentical, bioactive form, 5 -methyltetrahydrofolate. 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 DFH uses L-5-MTHF, the natural isomer, rather than the mixed (or racemic) form. Our L-5MTHF uses the patented folate derivative Quatrefolic®. This innovative form of folate has demonstrated high bioavailability and solubility as well as long lasting stability. Quatrefolic® L-5-MTHF helps to increase blood folate levels much better than folic acid.** (One bottle has 60 capsules total.)

Recommended Use: As a dietary supplement, take one capsule per day, or as directed by your health care practitioner.
