Sponsor: Vizja University in Warsaw

Summary

This randomized double-blind placebo-controlled trial will investigate the effects of multi-ingredient supplementation containing taurine, caffeine, and phosphatidylserine on physical performance, cognitive function, cognitive fatigue responses, recovery, sleep quality, and autonomic nervous system activity in elite male soccer players. Participants will complete a 14-day supplementation protocol and undergo football-specific performance, reaction-time, cognitive-fatigue, recovery, and sleep-related assessments before and after the intervention. The study aims to determine whether phosphatidylserine dose influences physical, cognitive, fatigue-related, and recovery-related outcomes when combined with taurine and caffeine.
