About Biolyz

Biolyz is a cutting-edge saliva-based biomarker testing platform powering actionable insights into athlete physiology, readiness, and performance. We deliver rapid, daily biomarker analysis across 125+ analytes that elite teams (including top European football clubs) rely on to predict injuries, optimize training loads, and elevate performance outcomes.
