Table 1.

Assessment of iodine intake in the general population based on median urinary iodine concentrations (UICs). Adapted from [15,16].

Median UIC	Iodine Intake	Nutritional Status
<20 μg/L	Insufficient	Severe iodine deficiency
20–49 μg/L	Insufficient	Moderate iodine deficiency
50–99 μg/L	Insufficient	Mild iodine deficiency
100–299 μg/L	Adequate	Optimal
≥300 μg/L	Excessive	Risk of adverse health consequences (iodine induced hyperthyroidism, autoimmune thyroid diseases)
