Donor human milk iodine concentrations (DHMIC) of study participants (n = 113) along with iodine intake variables, urine iodine concentration (UIC) and urine iodine creatinine ratio (UICR).

	Median (p25, p75)	Mean (±SD)
DHMIC (µg/L)	148.45 (97.61, 206.08)	163.36 (86.81)
Iodine intake (µg/day)
From food alone	103.60 (86.45, 125.80)	111.35 (46.99)
Total intake a	258.30 (153.70, 347.75)	254.6 (117.26)
UIC (µg/L)	112.41 (75.80, 160.10)	129.39 (73.76)
UICR (µg iodine/mg creatinine) b	0.10 (0.07, 0.15)	0.11 (0.06)

^a Sample size regarding total iodine intake (considering information from diet, iodized salt and iodine supplement intake) was n = 84 (missing data for 29 donors as iodine supplement intake and/or type or salt consumed during the dietary record was not reported), ^b n = 112 (due to 1 missing data).
