Is Phosphatidylserine Exercise Stress Randomized Trial safe?

Updated October 2026

Quick Answer

Phosphatidylserine Exercise Stress Randomized Trial has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: Conclusions Under the present 14-day experimental conditions, the multi-ingredient protocols containing taurine, caffeine, and phosphatidylserine were associated with more favorable selected cognitive and psychomotor outcomes, 30 m sprint performance, and baseline-adjusted GPS-derived locomotor outcomes than placebo.

Key Takeaways

  • 01Conclusions Under the present 14-day experimental conditions, the multi-ingredient protocols containing taurine, caffeine, and phosphatidylserine were associated with more favorable selected cognitive and psychomotor outcomes, 30 m sprint performance, and baseline-adjusted GPS-derived locomotor outcomes than placebo. [Mizera K (2026)]
  • 02Background/objectives Cognitive fatigue and impaired psychomotor function may contribute to reductions in football-specific performance during prolonged match-like activity. [Mizera K (2026)]
  • 03This study evaluated cognitive, psychomotor, sprint, and football-specific locomotor responses to multi-ingredient protocols containing taurine, caffeine, and either 300 or 600 mg·day -1 of phosphatidylserine in professional male football players. [Mizera K (2026)]
  • 04However, evidence on multi-ingredient protocols combining taurine, caffeine, and phosphatidylserine (PS) remains limited in professional athletes. [Mizera K (2026)]

[Mizera K (2026); evidence level 4] - Results : Compared with placebo, the TCP group was associated with more favorable physical, cognitive, and selected game-related outcomes ( p 2 = 0.13-0.20) and smaller fatigue-related declines in sprint performance (-18% vs. [Mizera K (2026); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
