Founded in 1979 shortly after the Three Mile Island accident, Anbex, Inc. is a U.S.-based manufacturer dedicated to public health, emergency preparedness, and national security. For nearly five decades, Anbex has focused on the development and production of potassium iodide (KI) products designed to help protect the thyroid gland during radiation emergencies. Our work supports governments, institutions, and individuals who rely on proven medical countermeasures when preparedness matters most.

Anbex is the manufacturer of IOSAT® , the only FDA-approved, full-strength potassium iodide tablet available in the United States for radiation emergencies. IOSAT® is formulated to help block the absorption of radioactive iodine by the thyroid following exposure during nuclear incidents. By saturating the thyroid with stable iodine, IOSAT® plays a critical role in reducing the risk of radiation-induced thyroid injury.

Since receiving FDA approval for its products in 1982, Anbex has been the largest supplier of potassium iodide in the United States. Our products have been trusted and deployed by major federal and state agencies, including the U.S. Department of Defense (DoD), Department of Homeland Security (DHS), and Department of Health and Human Services (HHS), as well as emergency management organizations, healthcare systems, and first responders nationwide. This longstanding trust reflects our commitment to quality, reliability, and regulatory compliance.

All IOSAT® products are manufactured under strict quality standards and in accordance with FDA requirements. We offer both adult (130 mg) and pediatric (65 mg) formulations to ensure appropriate dosing for all age groups. Each batch is produced with a focus on purity, potency, and consistency, providing confidence to those who depend on our products during critical situations.

At Anbex, preparedness is more than a mission — it’s a responsibility. We understand the vital role medical countermeasures play in emergency planning and public safety, and we take pride in supporting readiness efforts at every level. Through science, experience, and integrity, Anbex, Inc. remains committed to protecting lives and serving as a trusted partner in radiation emergency preparedness.
