Taking Potassium Iodide (IOSAT) helps saturates your thyroid with a beneficial form of iodine which prevents your body from absorbing radioactive iodine, thereby keeping you safe. The package of IOSAT contains 130 mg of Potassium Iodide which is a good, stable form of iodine your body can safely absorb. Each pill is scored so that it can be split into two 65 mg doses as well as smaller 32.5 mg doses for children.
