Studies were primarily of short (three to six6 weeks) duration with small samples size (10 to 157 participants), and most (61%) were published more than 20 years ago.
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 multiple meta-analyses including 2100+ participants showing benefits in mild dementia and memory. Effects modest and primarily in older adults or those with existing cognitive decline. Standardized extract (EGb 761) preferred.
