If you consume too many foods high in thiocyanates (soy, for example) then it disrupts your ability to process iodine, at which point you may think you're deficient but it's not because of intake. It can then be a problem when taking more and more. For a person avoiding such foods, who has an otherwise healthy diet, iodine supplements can be beneficial, especially when consuming large amounts of cruciferous vegetable, which can also inhibit iodine processing.

Taking regular supplements, though, is not going to put anybody in the danger zone.

…it should be noted that vegans are most at risk….because they consume a lot of soy as well as cruciferous vegetables: a combination that is likely to derail their iodine processing ability.
