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 is a trace element that is naturally present in some foods, added to others, and available as a dietary supplement. Iodine is an essential component of the thyroid hormones thyroxine (T4) and triiodothyronine (T3).odine in food and iodized salt is present in several chemical forms including sodium and potassium salts, inorganic iodine (I 2), iodate, and iodide, the reduced form of iodine [ 4 ]. Iodine rarely occurs as the element, but rather as a salt; for this reason, it is referred to as iodide and not iodine.
