Quatrefolic® is the patented form of 5-MTHF folate, the only form that is biologically active and directly usable by the body. Unlike conventional folic acid, it does not require conversion by the MTHFR enzyme, even in people with the MTHFR genetic mutation (up to 25% of the population, particularly the 677TT variant).
With Quatrefolic®, you are guaranteed maximum bioavailability, rapid and complete absorption, and optimal efficacy, whether or not you have the MTHFR mutation.
