Iodine

Iodine has both beneficial and harmful effects on human health. Iodine is needed by your thyroid gland to produce thyroid hormones. However, exposure to unnecessarily high levels of nonradioactive and radioactive iodine can damage the thyroid.

Iodine is found in many foods in small quanities.

Damage to the thyroid gland can result in effects in other parts of your body, such as your skin, lung, and reproductive organs.
