Iodine is obtained from Laminaria algae. Laminaria, also known as kelp, is a type of large brown seaweed that grows in underwater forests in temperate and arctic coastal regions. This algae is known for its high iodine content, making it a valuable source of the nutrient. Iodine is essential for thyroid function and is commonly used in medical and nutritional applications. Seaweeds like Laminaria are harvested and processed to extract iodine, which can then be used in supplements, food fortification, and other products. The availability of iodine from Laminaria plays an important role in preventing iodine deficiency disorders, such as goiter, in regions where iodine intake from other sources may be low.
