Thyroid hormones (thyroxine and triiodothyronine) contain iodine atoms. Iodine is an essential micronutrient required for the synthesis of these hormones. A deficiency of iodine leads to insufficient production of thyroid hormones, which in turn causes the thyroid gland to enlarge, a condition known as goitre, in an attempt to compensate and produce more hormones.
