Iodine and selenium work together to support optimal thyroid health.* Iodine is required for the production of thyroid hormones (T4 and T3), which regulate metabolism, growth, and development.* Selenium supports the enzymes that convert T4 to the active hormone T3 and helps maintain antioxidant status.* Balanced intake of both essential minerals is key to long-term thyroid function.*
