In the meta-analysis of categorical Hamilton Rating Scale for Depression-17 response, (three studies, N=483) adjunctive L-methylfolate was associated with a small effect versus antidepressant monotherapy (relative risk: 1.25, 95% confidence interval [CI]=1.08 to 1.46, p=0.004).
Folic acid/methylfolate for the treatment of psychopathology in schizophrenia: a systematic review and meta-analysis
Psychopharmacology (2018) · Meta analysis · n=925
Pooled FA + AP treatments were more effective than placebo + AP for negative symptoms (N = 5, n = 281; SMD = -0.25, 95% CI = -0.49, -0.01, p = 0.04, I2 = 0%).
Large meta-analyses show minimal to nonexistent benefits. Effects appear modest at best, with significant study heterogeneity. Combination with glucosamine may be more effective than chondroitin alone.
Based on meta-analysis showing small effect size for adjunctive L-methylfolate. RCT showed efficacy at high doses but effectiveness appears modest. Risk increases with higher doses due to overmethylation symptoms.
AI-estimated from published studies. Interpret as directional guidance.
