NCT ID NCT06441695
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether a slow-release caffeine pill (zümXR) could improve mood, alertness, and reduce side effects like jitters compared to regular caffeine after a night of poor sleep. Thirty-six healthy adults who usually drink moderate amounts of caffeine took part. They slept less than 5 hours, then took either the slow-release or regular caffeine and reported how they felt over several hours.
