Description: Iodine/Iodide is an essential element that is pivotal to normal function of the thyroid gland and the health and integrity of breast tissue. Iodine/Iodide intake has decreased significantly over the past thirty years and consequentially clinical symptoms have become apparent. Iodine/Iodide sufficiency can be readily assessed by analysis of urinary iodide excretion.
