Threshold ferritin and hepcidin concentrations indicating early iron deficiency in young women based on upregulation of iron absorption

This is the authors' abstract. We don't add key points for this paper.

Based on physiological upregulation of iron absorption, a threshold ferritin of <50 µg/L, corresponding to a threshold hepcidin of <3 nmol/l, indicates incipient iron deficiency in young women.
