Iodine is an essential nutrient, and insufficient intake is common. Iodine deficiency is on the rise for two reasons: decreased intake of iodine, and increased intake of bromine. The Iodine Plus urine test can help determine whether you have sufficient iodine and whether excess bromine could be negatively impacting your iodine status. Iodine Plus also includes selenium and cadmium. Selenium is an essential element for thyroid function, and cadmium is known to interfere with the actions of selenium.
