What it is

Potassium iodide is a chemical compound that combines potassium and iodine. It is a white crystalline solid that is soluble in water. It is often produced industrially by reacting potassium hydroxide with iodine.

Why it's used

Potassium iodide is primarily added to foods as a source of iodine, an essential nutrient. It is most commonly found in iodized salt, but can also be added to some dairy products, baked goods, and infant formulas to help prevent iodine deficiency.

Health notes

In the U.S., potassium iodide is Generally Recognized As Safe (GRAS) by the FDA when used as a nutrient supplement. Iodine is crucial for thyroid hormone production, which regulates metabolism. The World Health Organization (WHO) has evaluated iodine and its role in public health. While essential, excessive iodine intake can also affect thyroid function in some individuals.

Allergen info

Potassium iodide is not derived from any of the nine FDA major allergens. It does not contain gluten.
