Sports supplement cocktail tested on pro footballers

This study looked at whether taking a mix of taurine, caffeine, and phosphatidylserine for 10 days could help professional male football players perform better and feel less tired during training. Eighty-one players took either a placebo, a two-ingredient supplement, or the full three-ingredient blend. The goal was to see if these supplements could improve sprinting, reaction time, and overall game performance.
