L-5-methyltetrahydrofolate (L-5-MTHF), sometimes referred to as L-methylfolate, is the body’s most active form of folate and the one most commonly found in food. In general, folate is a form of B vitamin (vitamin B9) that occurs naturally in the diet and can also be taken in supplement form. Unlike other forms of man-made folic acid, L-5-MTHF is already in its metabolically active form, which means it can be easily assimilated and used by our bodies with no conversion needed. This especially benefits those that have genetic defects in “methylation,” which is actually quite common in the population. Active folate is essential to the formation of red blood cells, encourages healthy circulation and cellular repair, is considered brain food, and strengthens immunity through the formation of white blood cells. It is probably best known for its ability to support proper neurological tube formation in early pregnancy when taken in optimal amounts.
Our L-5-MTHF is an exceptionally pure second-generation folate made without the use of toxic solvents. It is a patented C-crystalline calcium salt, with high purity, stability, and excellent bioavailability.
