Why Iron is Critical for Endurance Athletes
Endurance athletes have increased iron needs due to exercise-induced losses, increased red blood cell production, and higher oxygen demands. Iron deficiency significantly impairs endurance performance.
Key Considerations for Endurance Athletes
- Exercise increases iron losses through sweat
- Higher red blood cell turnover
- "Foot strike hemolysis" from running impact
- Monitor iron status regularly
