Role of Iodine in Thyroid Function

Iodine is an essential mineral that the body needs to produce thyroid hormones, which play a crucial role in regulating metabolism, growth, and development. The thyroid gland, located in the neck, uses iodine to create hormones like thyroxine (T4) and triiodothyronine (T3). Without enough iodine, the thyroid can't function properly, potentially leading to health issues such as goiter (enlargement of the thyroid) and other metabolic disorders. Therefore, a diet rich in iodine—found in seafood, dairy, and iodized salt—is vital for maintaining healthy thyroid function and overall well-being.
