Iodine is an essential element and perhaps the biggest piece of the puzzle when it comes to thyroid hormones. One of Iodine’s main functions is in the production of thyroid hormones, but is detected in every organ and tissue. It is essential for healthy thyroid function and efficient metabolism, and there is increasing evidence that insufficiency correlates with numerous diseases, including fibrocystic breast disease and certain cancers. Iodine is a potent anti-bacterial, anti-parasitic, and anti-viral agent. It has four significant roles in your body, namely to maintain your weight and metabolism, to develop brain and cognitive function in children, to optimize fertility and to strengthen your immune system.
Please consult with your holistic healthcare provider before adding, or adjusting your dose of, an iodine supplement.
