For years we have been using Bacopa to improve memory. A recent PubMed search for Bacopa monnieri and memory yielded 21 results. A recent study compared Bacopa monnieri with placebo in adults older than 55 years of age. The participants not receiving placebo received 300 mg a day of Bacopa monnieri for 12 weeks.
The study showed that Bacopa monnieri significantly improved memory, delayed recall, and verbal learning compared to placebo.
There were some side effects in the Bacopa monnieri group such as an increase in abdominal cramps, nausea and stool frequency.
