Folate occurs naturally in many foods, particularly leafy green vegetables. L-methylfolate is a medical nutritional supplement used in patients that have conditions related to folate deficiency.
Function
Used for dietary management of low plasma or low red blood cell folate. Deplin is a medical nutritional supplement that provides the body with folate.
Other Information
Patients that become pregnant should inform their doctor about the pregnancy.
Patients that receive folic acid therapy for a prolonged period of time may experience a decrease in vitamin B12 serum levels.
Pharmacology
Peak Plasma Time: 1 hr
Metabolism: Liver
Excretion: feces (traces), urine (90%)
Mechanism of Action
L-methylfolate is the primary biologically active isomer of folic acid and the primary form of folate in circulation
Folic acid is a precursor of tetrahydrofolic acid, which is involved as a cofactor for transformylation reactions
These reactions are involved in the biosynthesis of thymidylates and purines of nucleic acids
The mechanism as an adjunct therapy in depression is unknown
