Summary

This study tested whether taking paraxanthine, a natural compound similar to caffeine, daily for 6 weeks could improve gaming performance, focus, and sleep in 60 healthy adults who were new to gaming. Participants were randomly assigned to receive either paraxanthine or a placebo, and their gaming scores, cognitive tests, mood, and heart rate were measured. The goal was to see if this supplement could give gamers an edge without the downsides of coffee.
