Iodine is an essential nutrient; potassium iodide is one supplemental form. The label should state iodine quantity rather than only the salt weight.
Sources: National Institutes of Health, Office of Dietary Supplements
What the reviewed evidence can and cannot show
NIH describes iodine as necessary for thyroid-hormone production and notes that both too little and too much iodine can affect thyroid function. This does not establish a need for an iodine supplement.
Sources: National Institutes of Health, Office of Dietary Supplements
