What Is Iodine?
Iodine is a chemical element widely used in healthcare, nutrition, pharmaceuticals, industrial processing, and specialty chemical applications. It is an essential micronutrient for humans and plays an important biological role in thyroid hormone production. In industrial markets, iodine and iodine compounds are valued for their chemical and functional properties and are used in applications such as X-ray contrast media, pharmaceuticals, optical polarizing films, catalysts, animal feed, fluorochemicals, iodophors, human nutrition, biocides, and other specialty products.
Commercial iodine is obtained from several natural sources, including caliche ore, underground brines, and seaweed. Caliche ore represents the leading source because of established extraction capabilities and availability in major iodine-producing regions. Because natural iodine resources are geographically concentrated, resource management, efficient extraction, processing quality, and supply chain stability are important considerations for producers and downstream users.
