Potassium iodideIodine

Potassium iodide is a chemical compound made up of potassium and iodine. It is often used in dietary supplements and fortified foods as a source of iodine, which is an essential mineral that the body needs for the proper functioning of the thyroid gland.

The thyroid gland uses iodine to make hormones that regulate metabolism and other important bodily functions. A deficiency in iodine can lead to thyroid problems, including hypothyroidism and goiter. Potassium iodide can help prevent iodine deficiency and its associated health problems.

In addition to its use in dietary supplements and fortified foods, potassium iodide is also used in medical settings to treat thyroid problems, as well as in emergency situations to protect against the harmful effects of radiation exposure.

Potassium iodide is generally safe when used in appropriate doses.
