RadBlock - Potassium Iodide Tablets (KI)

Item: KI-Canada
Shipping Info (Below)

RadBlock is a high potency iodine/potassium iodide supplement. This special combination of iodide and iodine helps saturate the tissues of the body with sufficient levels of iodine for disease prevention. Iodine is an essential element that is mainly used in the production of thyroid hormones by the thyroid gland, (although other organs in the body also require iodine in order to function normally).

Potassium iodide (chemical formula KI) is used also as a nutritional supplement to help the thyroid block and resist radioiodine exposure from the environment and ingestion of food. RadBlock thyroid blocking agent is intended for use in nuclear emergencies involving the release of radioiodine.
