The Claim
The prevalence of hyperthyrotropinemia in children aged 7–14 remains above 10% across iodine intake ranges of 200–300 μg/day, with no consistent difference between groups, indicating it is not a reliable indicator of iodine excess.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In children aged 7 to 14, the rate of elevated thyroid-stimulating hormone stays above 10% whether iodine intake is 200 or 300 micrograms per day, and this pattern does not change consistently with higher iodine levels.

When iodine levels go up or down within a certain range, the thyroid gland adjusts how much hormone it makes, and the brain keeps the signal to make more hormone steady, so TSH stays high in some kids no matter how much iodine they get.
What the research says
1 studyIn kids aged 7–14, even when they ate more iodine (like from salt or water), their TSH levels stayed around 10% high — so high TSH doesn’t tell us if they’re getting too much iodine.
