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.

Other food sources of iodine include shellfish, saltwater fish, eggs, dairy products, and seaweed.he thyroid needs iodine to produce thyroid hormone.
