Each standard package of Potassium Iodide (IOSAT) contains a strip of 14 tablets, each of which contains 130 mg of potassium iodide. The tablets are double-scored, so they can be easily and cleanly split into 65 mg and 32.5 mg child doses. All Potassium Iodide (IOSAT) is fully FDA approved for thyroid protection in a radiation emergency.
