BACOPA MONNIERI
Ayurvedic herb used for centuries to enhance memory, cognition, and reduce anxiety.
A 2014 meta-analysis of 9 RCTs (518 subjects) found Bacopa significantly improved cognition, particularly attention speed and choice reaction time, with chronic dosing of 12+ weeks. A double-blind RCT in elderly participants showed enhanced delayed word recall, improved Stroop task performance, and reduced anxiety and depression scores after 12 weeks at 300 mg/day. Twenty-two clinical trials reviewed in 2024 demonstrated reductions in pro-inflammatory biomarkers and oxidative stress alongside cognitive improvements. Evidence is strongest for chronic supplementation; acute effects are minimal. Most trials are small and lack head-to-head comparisons with established medications.
