Spearmint Extract Shown to Improve Cognitive Function
Spearmint has been used in traditional medicine for centuries, and has been associated with improved digestion, improved respiratory health, and stress relief. A new study has found that spearmint extract may also improve attention performance.
The study participants included 142 healthy, recreationally active men and women between the ages of 18 and 50. They were evenly divided into two groups by age and gender. One group took 900 mg of a spearmint extract that contained 14.5% rosmarinic acid and 24% phenolic content and the other group took a placebo daily for 90 days. Both groups took a number of cognitive assessment tests on days 0, 7, 30, and 90. The tests measured processing speed, attention, and continuous performance. The participants also filled out questionnaires regarding sleep, mood, and quality of life.
At the end of the study, participants who took the spearmint extract had an 11% increase in attention performance, compared to a 0.6% increase in the placebo group. No significant differences were seen in mood, sleep, or quality of life.
The study was conducted by researchers from MusclePharm Sports Science Institute. It was published online ahead of print on December 7, 2018 in the journal Nutrition Research.
