Iodine is an essential mineral that plays a vital role in the growth and development of children. It is necessary for the production of thyroid hormones, which are responsible for regulating metabolism and supporting brain development. However, many children do not get enough iodine in their diets, which can lead to iodine deficiency and a range of health problems. To address this issue, there are various iodine supplements available on the market specifically designed for children's health. These supplements are formulated to provide the recommended daily intake of iodine and support healthy growth and development.
