Iron Repletion for Runners
Iron repletion for runners restores ferritin after losses from mileage and menstruation. Test first, replete steadily, and ease training until energy returns.
Iron repletion for runners rebuilds ferritin after foot-strike hemolysis, menstrual losses, and low intake blunt endurance—flat intervals, high heart rate at easy pace, and cold intolerance are clues. Repletion needs guided labs, dietary iron with vitamin C, and often months of consistent intake; mega-doses without testing risk overload.

Can runners replete iron with food alone?
Mild deficiency may improve with heme iron, beans, and vitamin C pairing; moderate cases often need supplementation under labs. Retest ferritin every eight to twelve weeks.
