Episode Description from the Publisher

A single ferritin test isn't the whole story. Coach Nick and Coach Amanda talk with sports dietitian Callie Roseland about the difference between low ferritin, iron deficiency, and anemia, why runners are especially prone to running low, and the ferritin number that actually supports performance versus the number that just clears a lab's "normal" range.We also cover when to (and definitely not to) get iron labs drawn, how hard training affects iron absorption through a hormone called hepcidin, and why more iron isn't always better. GuestCallie Roseland, MS, RD, LDN, CSSD, IFNCP, EP-C is a Sports Dietitian who specializes in helping endurance and mountain athletes fuel for performance, recovery, and long-term health.
