Iodine is a trace mineral that the body converts into iodide. It's absorbed from the gastrointestinal tract into the bloodstream and then sent to the thyroid gland. Iodine is crucial to the good functioning and development of the thyroid gland and helps it produce thyroxine, a hormone that regulates the body's metabolism. About 30 percent of the iodine a person ingests goes to the thyroid gland. The kidneys absorb the rest, and any iodine left over is excreted.
A healthy thyroid gland supports the health of the skin, teeth, nails and hair. Iodine is also necessary to help the body convert carotene to vitamin A and to absorb carbohydrates from the intestines. It also helps ribosomes synthesize protein and helps the body make vitamin D.Learn more about Food Facts
