NCT ID NCT07376564
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested theacrine, a stimulant found in some teas, at higher doses than before. Nineteen healthy adults who regularly consume caffeine took different doses to see how it affected their blood pressure, heart rate, and mental focus. The goal was to see if theacrine could be a safer alternative to caffeine for people who want to avoid jitters or heart issues.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
theacrine
What this could lead to
If it works, theacrine could become a caffeine alternative for people who want a stimulant with fewer side effects.
What could go wrong
This is a small, early study with only 19 people, so results may not apply widely. High doses might still cause side effects like jitters or blood pressure changes.
