Iodine is an essential trace mineral that is important for human health in various ways. This mineral is required for the thyroid gland to be able to produce thyroid hormones which play a role in metabolism and weight control.
Although its highest concentrations are in glandular tissues, especially the thyroid gland, iodine is found in and utilized by all cells, tissues and systems in the body.
It is necessary for DNA maintenance, cognitive ability, immune function, energy metabolism and cardiovascular health. Some prominent researchers and doctors believe that as many as 19 of 20 people lack sufficient iodine in their diets.
