This is a sponsored partner episode with Eternal, a company focused on helping athletes and active people better understand their health. Eternal’s Foundations membership tracks over 70 biomarkers with athlete-specific reference ranges and turns that data into actionable steps for fueling, recovery, and long-term health.

In this conversation, Eternal’s lead performance dietitian Kelsey Bailey walks us through:

• Why athletes might want to include biomarker testing in their training toolkit

• Which blood markers are most important—and which often get overlooked

• How to interpret results without getting lost in data

• Practical ways to translate your health data into better fueling and performance
