Estimated dietary iron absorption for selected serum ferritin values in men and women.

1A serum ferritin cut off of 15 µg/L was used by the IOM to identify iron deficient individuals [11], 30 µg/L was used by Reddy et al. [25] for estimating non-heme iron bioavailability from meal composition, 60 µg/L is the value above which no homeostatic up-regulation of iron absorption occurs [40].2Estimated bioavailability adjusted for the effect of iron stores based on the ratio 45/SF cutoff.Estimated dietary iron absorption for selected serum ferritin values in men and women.
