Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/26898294

Methylenetetrahydrofolate reductase (MTHFR) is an enzyme required for the formation of 5-methyltetrahydrofolate (5-MTHF), a form of folate able to cross the blood-brain barrier and which is necessary as a substrate for the remethylation of homocysteine to methionine by methionine synthase. Patients with severe MTHFR deficiency cannot make 5-MTHF and have extremely low levels in the CSF. Only treatment with oral 5-MTHF given as calcium mefolinate resulted in an increase in CSF 5-MTHF.

Sample Use Guides

In Vivo Use Guide

calcium mefolinate at doses of 15–60 mg/kg/day

Route of Administration: Oral

In Vitro Use Guide

To study the actions of 5-methyltetrahydrofolate (5-MTHF) as an antioxidant, the effects of 5-MTHF (10, 100, and 1000 μmol/L) on superoxide generation by purified recombinant eNOS and xanthine oxidase/hypoxanthine were investigated. 5-MTHF dose-dependently reduced superoxide production by both xanthine oxidase and eNOS.
