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.
A low-iodine diet contains less than 50 micrograms (mcg) of iodine per day. Iodine is a mineral. It plays an important role in several processes that take place in your body. One role is the production of a hormone called thyroxine in the thyroid gland.
