Iodine enters the body through iodine-rich foods, including certain salts (âiodized saltâ), eggs, sea vegetables and fish. We rely on iodine to create thyroxine (T4 hormone) and triiodothyronine (T3), two of the main hormones produced by the thyroid that control numerous important functions.
Iodine, a trace element found in soil, is an essential component of the thyroid hormones involved in regulating the body's metabolic processes. Iodized salt and seafood are the major dietary sources of iodine. In the United States, salt is iodized with potassium iodide at 100 parts per million (76 milligram [mg] of iodine per kilogram [kg] of salt).
