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.
In general, foods from the sea contain the most iodine, followed by animal foods, then plant foods. Of all foods, seaweed (like kelp), is the most well known and reliable source of natural iodine. Egg and dairy products can also be good sources. Select Food Samples for Iodine Content.
