Iodine is an element that's required for the thyroid gland to produce thyroid hormones. Since the body does not produce iodine on its own, it needs to come from dietary sources—and striking the right balance is key.

Radioactive iodine therapy for thyroid cancer is most effective in people who have high levels of thyroid-stimulating hormone, or TSH. This hormone is produced by the pituitary gland, which is located at the base of the brain and produces many hormones. TSH "tells" the thyroid to absorb iodine, which is then converted to thyroxine.Web
