The study, performed at the Centre for Human Psychopharmacology at Swinburne University in Melbourne, Australia, and is one of the first to show curcumin can improve brain function in healthy older adults.
One hour after treatment with a single 400-mg capsule of Longvida, participants in the Longvida group showed superior performance over the placebo group on validated tasks relating to attention and working memory (p<0.05). In addition, 30-day supplementation improved measures of calmness, contentedness and fatigue versus placebo (p<0.05 and p<0.01). The study included 60 participants, and no dropouts or side effects were reported.
"Behavioral measures showed that even at the low dose implemented here (approximately 80 mg), curcumin has the potential to improve important cognitive functions, reduce fatigue and improve resilience to the detrimental effects of psychological stress on mood," the authors wrote.
The authors also suggested a possible mechanism by which the effects of Longvida to support energy were observed: "Curcumin may help to combat fatigue by improving the maintenance of energy levels and ability to meet energy demands through its effects on mitochondrial function, AMP-activated protein kinase and glucose uptake and regulation."
