A group of researchers from the University of Swinburne in Melbourne, Australia, recently published the results of a randomised, double-blind, placebo controlled study.
During 28 days, 60 participants from 60 to 85 year old took 400 mg/day of either the patented SLCP LongVida curcumin complex of Optim Curcuma (80 mg curcumin) or placebo.
The authors reported that the curcumin supplementation significantly improved both acute and chronic cognitive functions, particularly working memory tasks, general fatigue and calmness, compared with placebo.
