Iodine deficiency can lead to thyroid problems and other health issues that can be a result of lack of iodine in our daily diets. Because the body can't produce iodine, humans rely on iodine-rich foods and salts to receive the iodine their body needs. Our Brain Basics Ultra Iodine Complex supplement provides an easier and more convenient way to increase your daily intake. One tablet contains 12.5 mg of iodine complex or 7.5 mg potassium iodide, and 5 mg iodine for effective thyroid support. One container of our iodine supplement has 90 tablets with a serving size of one (1) tablet per day. The Ultra Iodine Complex is one of the proprietary Basic Formulas from Brain Bean, a company founded and created by Dr. Michael Nelson, DC. All our products use only the finest, premium ingredients.
