Abstract
Meta-analysis of randomized controlled trials of Bacopa monnieri extract on cognitive performance.
Key Findings
Bacopa significantly improved speed of attention (Trail Making Test and choice reaction time) but most memory subtests were not significantly improved.
Conclusions
Bacopa has the potential to improve cognition, particularly attention speed; larger well-designed trials are needed.
Limitations
High heterogeneity, varied extracts and doses, small trials.
Supplements Studied
