Levomefolic acid is a folate supplement used to prevent neural tube defects in pregnancy or folate deficiency.
Levomefolic acid plays a critical role in methylating homocysteines into methionine by acting as a methyl donor in a reaction catalyzed by vitamine B12-dependent methionine synthase. Homocysteine must either be further metabolized via transulfuration to become cysteine, taurine, and glutathione via a B6-dependent process, or re-methylated to become methionine again. Methionine formed from remethylation of homocysteine by levomefolic acid forms the downstream metabolite S-adenosylmethionine (SAMe), which is involved in numerous biochemical methyl donation reactions, including reactions forming monoamine neurotransmitters . Studies suggest that high plasma levels of homocysteine is associated with increased incidences of arterial plaque formation .
For the treatment and prevention of folate deficiency and for use as an antidote against folic acid antagonists. Contained in oral contraceptives to reduce the risk of neural tube defects arising from folic acid deficiency for pregnant women who conceived during use or shortly after the discontinuation of the product.
