Your spice rack may contain the safest, most fast-acting, brain-boosting substance medical science has yet to confirm effective in a human clinical study.
A remarkable new study published in the Journal of Psychopharmacology titled, “Investigation of the effects of solid lipid curcumin on cognition and mood in a healthy older population,” reveals that the primary golden-hued polyphenol found in the ancient Indian healing spice turmeric known as curcumin is capable of improving cognition and mood in elderly adults (60-85) when administered in either short-term [acute], chronic, or short-term-on-chronic dosage schedules.
The study involving 60 healthy adults found that a single dose of 400 mg of a solid curcumin formulation (trade name Longvida® (non-affiliate link)) resulted only one hour later in significantly improved performance on sustained attention and working memory tasks, compared with placebo.
Additionally, a chronic treatment schedule (4 weeks) resulted in improvement in working memory and mood, the latter of which was defined as a positive change in their “state [of] calmness, contentedness and fatigue induced by psychological stress.”
Finally, an acute-on-chronic treatment resulted in improved alertness and contentedness.
The authors commented that,
“To our knowledge this is the first study to examine the effects of curcumin on cognition and mood in a healthy older population or to examine any acute behavioral effects in humans. Results highlight the need for further investigation of the potential psychological and cognitive benefits of curcumin in an older population.”
