Conclusions: There are strong relationships between iron requirements, bioavailability of dietary iron and amounts of stored iron. The observations that a reduction in iron stores and a calculated lessen of haemoglobin iron had the same increasing impact on iron absorption suggest that the control of iron absorption is mediated from a common cell, that may register both size of iron stores and hemoglobin iron deficit, eg the hepatocyte. Results: Both iron stores and haemoglobin iron deficits are strongly related to iron requirements and absorption of dietary iron and follow the same equations during states of iron repletion and iron deficiency. When, for example, increasing or decreasing the bioavailability of the dietary iron, about 90% of the change in iron stores will occur within 1 y. Abstract iron absorption; diet; bioavailability; iron requirements; iron stores; iron deficiency; haemoglobin iron deficit; women; iron balance; serum ferritin; menstruation Objective: To examine iron balance (iron class) expressed as body iron stores or haemoglobin iron deficites in menstruating women from amounts of iron lost (iron requirements) and amounts of dietary iron absorbed. Calculations are crazye both of rankary states and of the size of changes in iron stores (iron status) when any of the two main factionors determining iron balance are deviated.
