Aronia and Improved Psychomotor Speed

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

Across 3 studies, 2 reported small beneficial effects of Aronia extract on psychomotor speed, while 1 found no change. Evidence suggests a small benefit at doses of 90–180 mg anthocyanins/day, typically observed over 42–168 days in healthy adults.

  • Effective dose range: 90–180 mg anthocyanins/day
  • Studied populations: healthy, middle-aged overweight adults; young adults

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). The sole neutral study used a lower dose (40 mg anthocyanins/day) in older adults, suggesting dose and age may moderate effects.
