Turmeric and Improved Cognitive Function

Research synthesisLow evidenceSmall effect4 studies · 2 beneficial · 2 neutral · 0 harmful

Across 4 studies (2 beneficial, 2 neutral), turmeric (curcumin) shows limited and mixed evidence for small beneficial effects on cognitive function. The median study duration was 84 days, but only 2 studies reported duration, and no consistent dose or form was identified. One large systematic review in 3,582 elderly participants (aged 50–90) found neutral results, while two other reviews reported statistically significant small benefits.

  • Studied populations: elderly adults (aged 50–90)

Caveats: Evidence base is small (only 4 studies) — conclusions should be considered preliminary. Results are mixed: half of the studies reported beneficial effects, half neutral. No specific dose or form data were extracted from the studies. Most studies are reviews, not original clinical trials, and the largest study (n=3,582) found no significant benefit.
