This study is a 12-week, double-blind, placebo-controlled trial of L-methylfolate 15 mg/d supplementation in schizophrenia patients with mild or greater negative symptoms. L-methylfolate, a prescription medical food, is the activated form of folate required for conversion of homocysteine to methionine and hence is the optimal form of folate for supplementation, since it eliminates the need for activation by MTHFR. The purpose of this study is to examine the change in plasma L-methylfolate concentrations following a three-month trial of L-methylfolate 15 mg/d compared to placebo.
Blood levels of L-methylfolate and biological activity will be evaluated by examining changes in plasma homocysteine concentrations, serum methionine concentrations and changes in brain activation as measured by fMRI.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Supportive Care
