Figure 14-2 Schematic representation of the kinetics of iodide in healthy non-pregnant and pregnant adults. Panel A: non-pregnant adult with an adequate iodine intake of 150 µg/day. Panel B: non-pregnant adult with a restricted iodine intake, corresponding to 70 µg/day. Panel C: the latter condition is compared with an identically restricted level of iodine intake (i.e. 70 µg/day) in a pregnant woman. Daily TH production was set at 80 µg of iodine/day (in non-pregnant) and increased by 1.5-fold to 120 µg/day during pregnancy (from Glinoer, Ref 22).
