Iodized salt
Table salt with a small amount of iodine added, usually as potassium iodide, to prevent iodine deficiency and goitre.
In the United States, Morton began selling it in 1924 after a Michigan medical group urged producers to add iodine. In Canada, salt sold for table or household use must contain potassium iodide (0.01%); sea salts and salt sold for a named use, such as pickling salt, are exempt.
