Iodine is a critical component of thyroid hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones play significant roles in growth, development, and metabolic regulation. An imbalance in iodine levels can lead to conditions such as hypothyroidism, goiter, and in severe cases, intellectual disabilities. Thus, maintaining adequate iodine levels through diet and environmental exposure is essential for health.
