Pharmacology

Mechanism of Action

Methylfolate, or L-methylfolate, is the active form of folate in the body, which can be transported into peripheral tissues and across the blood-brain barrier. Folate is necessary for formation of numerous coenzymes in many metabolic systems, particularly for purine, pyrimidine, and nucleoprotein synthesis, and maintenance in erythropoiesis; stimulates WBC and platelet production in folate deficiency anemia.
