Iodine is an essential mineral that is important for human health. It is found in many foods, but the most common source of iodine is SEAWEED and KELP. SEAWEED is a type of algae that grows in saltwater and is often used as a food source or for medicinal purposes. KELP is a type of SEAWEED that is found in colder waters and is also used as a food source or for medicinal purposes. Both SEAWEED and KELP are rich sources of iodine, providing a natural way to get the mineral into the body.
