Iodine Market Overview 

The global Iodine Market, valued at approximately USD 3.87 billion in 2023, is anticipated to grow at a compound annual growth rate (CAGR) of 5.53%, reaching nearly USD 5.64 billion by 2030. This growth is primarily fueled by the increasing demand for iodine in medical imaging, electronics, and agriculture. 

The thyroid hormones triiodothyronine and thyroxine, as well as the production of proteins and enzyme activity, are all regulated by the mineral iodine, which is found in various diets. Iodine is necessary for the body to produce thyroid hormones. Many types of seaweed include iodine, a chemical component that combines with starch to turn purple. Numerous industrial, medical, and nutritional applications call for iodine and its derivatives. Brine and saltwater have almost the same amount of salt in them.
