Bacopa monnieri: Preclinical and Clinical Evidence of Neuroactive Effects, Safety of Use and the Search for Improved Bioavailability
Nutrients (2025) · Systematic review
Animal studies have shown promising results in reducing symptoms and protecting against neurodegeneration.
Based on RCTs showing cognitive improvements in healthy adults and dementia patients. Effect sizes were modest and some studies used combination therapy. Higher doses associated with increased headache risk.
Based on meta-analysis of 437 participants showing improvements in attention, processing speed, and working memory. However, one large RCT (n=101) found no significant between-group differences. Effects may take 8-12 weeks to manifest. Standardized extracts (Bacognize, Synapsa) may have better bioavailability than generic forms.
