The Impact of 5-Hydroxytryptophan Supplementation on Cognitive Function and Mood in Singapore Older Adults: A Randomized Controlled Trial
Nutrients (2025) · Rct · n=30
Results: A significant time effect was observed in the MoCA score, which was mainly explained by a significant increase in the 5-HTP group (week 0 vs. week 12: 26.6 ± 1.4 a.u. vs. 27.6 ± 1.4 a.u., p < 0.05).

Systematic Review and Meta-Analysis of L-Methylfolate Augmentation in Depressive Disorders
Pharmacopsychiatry (2022) · Meta analysis · n=6707
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%).
Limited evidence from small RCTs (n=30, n=166). Effectiveness constrained by mixed study populations and preliminary findings. Higher doses associated with increased nausea risk.
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.
Methylfolate has a higher evidence score (9/10 vs 8.5/10) and wins in 3 of 3 categories.
For support mood, Methylfolate has a higher relevance score (85 vs 75).
