Urinary iodine concentration and habitual iodine intake from food and supplements in young Norwegian women (n = 403).
| Mean ± SD | Median | p25 | p75 | |
|---|---|---|---|---|
| Urinary iodine concentration, µg/L | 94 ± 76 | 75 | 42 | 130 |
| Habitual iodine intake | ||||
| Iodine from food, µg/day | 104 ± 58 | 92 | 68 | 122 |
| Iodine from supplements (users only) a, µg/day | 106 ± 60 | 129 | 43 | 150 |
| Total iodine intake, µg/day | 114 ± 68 | 100 | 69 | 135 |
| Estimated iodine intake from UIC b, µg/day | 149 ± 125 | 117 | 62 | 191 |
a Supplement users (n = 38) b Estimated iodine intake from UIC were calculated using the following equation: UIC × 0.0235 × weight (kg) [28].
