Iodine supplements are a type of dietary supplement that provide the body with an essential mineral that is necessary for proper thyroid function. Iodine is important for the production of thyroid hormones, which regulate metabolism and other important bodily functions. While iodine is found naturally in some foods, such as seafood and seaweed, it can be difficult to get enough through diet alone. Iodine supplements can help to ensure that individuals are getting the recommended daily amount of iodine, which can help to promote overall health and wellbeing.
