A naturally occurring substance, iodine is an essential nutrient that supports a wide range of normal bodily processes, including your metabolic and thyroid functions. Potassium iodide (KI) is a salt of stable (not radioactive) iodine. This important chemical is necessary for your body to produce thyroid hormones. Without sufficient iodine, your thyroid is forced to work harder, resulting in unnecessary stress.
During a radiological or nuclear emergency, you may be exposed to radioactive iodine through the food you eat or even the air you breathe. Fortunately, your thyroid can only absorb a limited amount of iodine at a time. This means that supplementing with stable, non-radioactive iodine can help keep your thyroid from absorbing radioactive iodine, thereby supporting optimal thyroid health.
