What is L-methylfolate, and what is it used for?

L-methylfolate is the active form of vitamin B9, also known as folate that naturally occurs in many foods. L-methylfolate is a prescription medical food used to supplement folate deficiency in people with major depressive disorder or schizophrenia, and megaloblastic anemia, a form of anemia caused because the bone marrow produces large, immature and structurally abnormal red blood cells.

L-methylfolate is a water-soluble vitamin crucial for several cellular functions including DNA synthesis, amino acid synthesis and growth of healthy cells, particularly, red blood cells. L-methylfolate is a cofactor in the production of chemicals (neurotransmitters) in the brain including serotonin, dopamine and norepinephrine. L-methylfolate is the more effective form of folate that can cross the blood-brain barrier and is more readily available for cellular functions.

L-methylfolate is naturally available as folate from many foods, including leafy green vegetables, legumes, eggs, beef liver, fruits and vegetables. People also take folic acid, the synthetic form of folate, as a supplement. Folic acid and l-methylfolate cannot be used interchangeably because folic acid or folate must be converted by the body into L-methylfolate for the cells to be able to use it, and some people may have genetic conditions that affect this ability.

Warnings

  • Do not take if you have hypersensitivity to L-methylfolate or any of its components
  • L-methylfolate must not be used as a monotherapy for megaloblastic or pernicious anemia if the patient also has vitamin B12 deficiency
  • Doses of L-methylfolate greater than 0.1 mg/day may mask B12 deficiency pernicious anemia while irreversible nerve damage continues to progress
  • L-methylfolate must be taken only under a physician’s supervision
  • L-methylfolate therapy for a prolonged period of time may cause a decrease in vitamin B12 levels

Pregnancy and breastfeeding
