Objective: To investigate the effect of simultaneous administration of [6S]-5-methyltetrahydrofolic acid ([6S]-5-CH3H4PteGlu) with L-ascorbic acid (L-AA) on serum folate concentrations in healthy male subjects. Subjects and methods: A total of nine healthy male volunteers were recruited. Serum...
Folic acid fortification has been introduced in several countries to reduce the incidence of neural tube defects. However, it could mask the hematologic signs of vitamin Bdeficiency. L-5-methyltetrahydrofolic acid (MTHF), which is unlikely to mask vitamin Bdeficiency, may be a safer fortificant,...
