Iodine supplements are commonly used for immune support and overall health. Iodine is an essential mineral that plays a critical role in thyroid function, which in turn affects the immune system. A healthy thyroid gland is important for maintaining a strong immune system, and iodine helps to regulate thyroid hormones. Iodine supplements can also help to support healthy metabolism, energy levels, and cognitive function. Additionally, iodine has been shown to have antimicrobial properties, which can help to fight off infections and support the immune system. Overall, iodine supplements can be a beneficial addition to a healthy diet and lifestyle for immune support.
