It is through the diverse actions of thyroid hormones that iodine becomes important in the regulation of a number of different physiologic systems.
These hormones are also essential for protein synthesis, tissue growth (including the formation of healthy nerves and bones), and reproduction. These hormones are important for correct neuro-development. An adequate intake of iodine is necessary for the correct function of the thyroid and normal levels of thyroid hormones.
A second major organ of iodine uptake is the breast. Iodine is essential for developing child. If iodine is unavailable during development, the child can developed hyperthyroidism. Small amounts of iodine found in bile, hair and skin, stomach and mammary glands act as storage sites that may endogenously supply the body with iodine when the need exists.
Failure to have proper amounts of this element during development or in adulthood can lead to a host of medical problems, including mental retardation, cardiac complications, metabolic disturbances and mental health illness.
