In this 4- month, double-blind trial, administered on 49 women aged 60-80, supplementation using 800 mg/day DHA omega 3 essential fatty acids and 12 mg/day lutein carotenoids were found to improve memory scores and rates of learning. Measures of mental processing speed, accuracy and mood were not affected by supplementation.
