Daily supplementation with cumin essential oil (CEO), rich in cuminaldehyde, for 12 weeks significantly improved cognitive performance in older adults (65–86 years) compared with placebo. Participants receiving CEO demonstrated notable enhancements in psychomotor speed and reaction time, indicating improved processing speed and cognitive responsiveness. While certain blood biomarkers changed over time, these effects were not specifically attributable to CEO supplementation. Overall, the findings suggest that CEO may support cognitive function and healthy aging in the elderly, highlighting its potential as a natural nutraceutical ingredient for promoting brain health and extending healthspan.
