Potassium Iodide: The Difference Between Low vs. High Doses

Potassium Iodide (KI) is a salt of stable iodine used to iodize salt and as a medication or dietary supplement for thyroid health.

You may notice different dosages of potassium iodide supplements at your local health food store and wonder what the differences are. Let's take a look at the options:

1. General thyroid protection: 

Lower doses of potassium iodide are used in cases of overactive thyroid (hyperthyroidism) and to prevent iodine deficiency. It is also helpful for a skin condition called sporotrichosis.

2. Emergency use:

Higher doses of potassium iodide are used as a thyroid blocking agent for use in nuclear emergencies which involve the release of radioiodine. Not for daily use; for nuclear emergency use only.

Take as directed by a public official if a nuclear emergency should happen. Take just before or shortly after exposure to radioiodine.
