Changes in hepcidin and iron concentrations and the percentage TSAT during un-supplemented pregnancy from the graphs of van Stanten et al. [44].

	T1	T2	T3
Blood Hepcidin (nmol/L)	1.85 [1,2,3,4]	<0.5 *	<0.5 *
TSAT (%)	25 [15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35]	20 [14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34] *	10 [7.5–15] *
Blood Iron (µmol/L)	15 [11,12,13,14,15,16,17,18,19,20,21,22,23,24]	15 [11,12,13,14,15,16,17,18,19,20,21,22,23,24]	9 [8,9,10,11,12,13,14,15] *

* Statistical difference between first and second trimester, or first and third trimester. TSAT: transferrin saturation.
