Iodised Salt

Iodized salt is common table salt (sodium chloride) that has a small amount of iodine added to it. This iodine is typically in the form of potassium iodide or potassium iodate, which are mixed into the salt during processing.

Manufacturers add iodized salt to foods primarily to provide iodine, an essential nutrient for human health. It is commonly used in table salt sold for home use and can be found in some processed foods to help prevent iodine deficiency.

In the US, salt (sodium chloride) is generally recognized as safe (GRAS) by the FDA. Iodine is an essential nutrient, and the FDA permits the addition of iodine compounds to salt. Iodine is vital for proper thyroid function and overall health. Both JECFA and EFSA have evaluated iodine, recognizing its importance as a nutrient. While iodine is necessary, consuming too much or too little can have health effects. The FDA's Daily Value for sodium is 2,300 mg.
