Iodine is a component of the thyroid hormones thyroxine and triiodothyronine, which help regulate cell activities.
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.
