Summary

This study gives 100 professional male football players a daily mix of taurine, caffeine, and phosphatidylserine (or a placebo) for 14 days. Researchers measure sprint speed, cognitive function, fatigue, recovery, and sleep before and after. The goal is to see if the supplement helps players perform better and recover faster.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
taurine, caffeine, and phosphatidylserine supplements
What this could lead to
If successful, this could point toward an optimal supplement combination to boost physical and mental performance in athletes.
What could go wrong
This is a small, short-term study in elite male athletes only, so results may not apply to others. The effects may be minor or not translate to real-game performance.
