Potassium Jodide

Potassium iodide is a chemical compound that is a salt of potassium and iodine. It is typically produced industrially through chemical synthesis. It is often found as a white crystalline solid.

Potassium iodide is added to foods as a source of iodine, which is an essential nutrient. It is commonly found in iodized salt, but can also be added to other processed foods like seasonings and some beverages.

Potassium iodide is generally recognized as safe (GRAS) by the FDA when used as a nutrient supplement. Iodine is crucial for thyroid hormone production, and deficiency can lead to health problems. The WHO has also evaluated iodine and its role in public health. Typical intakes from iodized salt are considered safe and beneficial for preventing iodine deficiency disorders.
