The study, not yet published, is a follow-up to a 2015 study, also in older adults, that found that Longvida was associated with improved working memory and mood, including improvements in general fatigue and calmness.
Longvida, a curcumin ingredient designed for improved bioavailability, was shown in a recent study to support mood and working memory in older adults, reports the ingredient’s supplier, Verdure Sciences (Noblesville, IN). This new study, not yet published, is a follow-up to a 2015 study1, also in older adults, that found that Longvida was associated with improved working memory and mood, including improvements in general fatigue and calmness caused by psychological stress. Both studies were conducted by researchers at Swinburne University (Australia).
The latest unpublished study2 tested the effects of a daily dose of 400 mg of Longvida, versus placebo, for 12 weeks in 80 adults aged 50-80. At baseline and at 4 and 12 weeks, subjects were tested for cognitive performance, measures of mood, cardiovascular function, and other blood biomarkers.
Compared to placebo, researchers said, Longvida subjects experienced decreased tension, anger, confusion, and total mood disturbance at 4 weeks, with lower fatigue scores at both 4 and 12 weeks. They also experienced improvements in working memory.
In a press release, lead researcher Andrew Scholey, PhD, director of the Centre for Human Psychopharmacology at Swinburne University and a professor of behavioral and brain sciences, said of the study: “We should exercise some caution as the study hasn’t yet undergone full peer review (although the conference abstracts were peer reviewed). Nevertheless, the results of our second trial broadly support and extend the effects of the first study. We are currently further examining the effects of Longvida on hippocampal functioning.”
Verdure Sciences says it expects full publication of the study sometime this year.
