Purpose : This study was undertaken to clarify the effect of heme-iron supplementation on the prevention of iron-deficiency anemia in male collegiate distance runners.Methods : Forty-one male collegiate runners were divided into three groups, consisting of a heme-iron group (HI), a citrate-iron group (CI), and a non-iron group (NI). Iron tablets (heme-iron or citrate-iron) were administered at a dose of 7 mg per day for two months. The blood components and nutritional intakes were estimated before and after the intervention.Results : The nutritional intakes did not differ among the three groups. The red blood cell, hemoglobin, hematocrit, ferritin, Glutamic-Pyruvate Transferase and <i>γ</i>-Glutamyl Transpeptidase levels were unchanged throughout the experimental periods. After the intervention, the serum iron levels significantly decreased in the NI group but not in the iron-supplemented groups, while the reticulocytes counts increased among the three groups.Conclusion : The small amount of heme-iron supplementation was thus found to have a preventive effect on iron deficiency anemia without causing any negative side affects.
