Potassium iodide or SSKI (saturated solution of potassium iodide) is an inorganic salt that combines iodine and potassium in a relatively high dosage. A saturated solution of potassium iodide or the salt taken in tablet form can act as a potent antibiotic against a variety of pathogens.

This potassium and iodine solution is also the standard prophylactic treatment for radiation exposure, as potassium iodide saturates the thyroid with iodine, which in turn prevents the body from taking up radioactive iodine isotopes from the environment.

Caution: SSKI/Potassium Iodide is not typically taken as a nutritional supplement, since it provides a dosage many times above standard nutritional requirements for iodine.

Natural Cures: Potassium iodide can provide your everyday iodine supplements and can also be used in the case of radiation exposure, against fungal skin infections, as an expectorant, and as a general antibiotic.
