Potassium iodide and potassium iodate can protect the thyroid gland from the effects of radioactive iodine in the event of a nuclear accident, drastically reducing the risk of thyroid cancer. However, they are only effective if taken before or very shortly after exposure to radiation. These products, which are sold as both supplements and over-the-counter drugs, are typically sought by people living close to nuclear reactors and by others who may be exposed to radiation during nuclear accidents.
 
ConsumerLab.com purchased and tested six products to determine if they contained the labeled amounts of active ingredient. Tablets were further tested to determine if they disintegrated properly in solution — necessary for absorption by the body.
