Study
Spearmint Extract May Enhance Agility in Active Adults
Daily spearmint extract improved reaction time and agility in young, active individuals over 90 days.
Summary
In plain language
In a recent study, researchers investigated whether a special spearmint extract could improve agility and reaction time. The study included active men and women who took 900 mg of the extract daily for 90 days. Results showed that those who took the spearmint extract had better reaction times and were quicker on their feet compared to those who took a placebo. While this study focused on younger adults, the findings suggest that spearmint extract might help improve mental sharpness and physical agility, which could be valuable for maintaining an active lifestyle. It’s important to discuss any new supplements with your healthcare provider.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
This study used a carefully controlled method where participants took either spearmint extract or a placebo without knowing which one they received. The researchers measured how quickly participants could respond to signals and change directions, a skill known as reactive agility. Key findings included improved reaction times and more hits on agility tests in those taking the spearmint extract. While these results are promising, they were observed in a younger, active group, so more research is needed for older adults. Seniors interested in maintaining agility may consider discussing spearmint extract with their healthcare provider to see if it's right for them.

Research Quality Score
Scored September 29, 2026 using rubric mq-1.8_2026-07-06.
Assessment
The study scored well in design and bias control due to its randomized, double-blind, placebo-controlled methodology. Statistical integrity was strong with pre-specified endpoints and adequate power. However, transparency was limited by retrospective registration and data sharing only upon request. The conflicts score was low due to industry funding and author affiliations. The study's relevance to the target population was poor, and journal quality could not be assessed.
