Turmeric and Improved Cognitive Function

Research synthesisLow evidenceSmall effect3 studies · 2 beneficial · 1 neutral · 0 harmful

Across 3 studies, 2 reported small beneficial effects on cognitive function, while 1 found neutral results. Both beneficial studies reported statistically significant findings. Median study duration was 56 days, observed in the neutral systematic review of 3,582 elderly participants (aged 50–90). No clear dose range or supplement form was consistently reported across studies.

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

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. One of the beneficial studies is a narrative review with low evidence quality (score 2), and the highest-quality study (systematic review, score 8) showed neutral effects. Effect size was uniformly small across all studies.
