Primary

Measure	Time frame
Assessment of the incorporation of 57Fe related to 58Fe into erythrocytes 14 d after administration and calculated based on isotope-dilution.	—

Secondary

Measure	Time frame
Whole blood will be collected at recruitment for the analysis of Hb, Hb type, serum ferritin (SF), transferrin receptor (TfR), C-reactive protein (CRP), erythropoietin (Epo), serum iron (SI), total iron binding capacity (TIBC), and transferrin saturation (TfSat). Anemia will be defined as a hemoglobin concentration	—
