From: Physiological requirements for iron in women of reproductive age assessed by the stable isotope tracer technique

calculating method n weight (kg) iron physiological requirement adjusted by weight (μg.kg−1.d− 1) iron physiological requirement (mg/d) reference weight (kg) EAR (mg/d) RNI (mg/d)
formula calculation method 21 64.87 23.63 1.55 56 13 18
linear regression method 33 64.31 20.98 1.29 56 11 15
recommended value   56 26.25 1.47 56 15 20
