Iodine is a trace element required for thyroid hormone production. Thyroid hormones regulate metabolism, growth, and development. Iodine deficiency is the most common preventable cause of intellectual disability worldwide and can cause goiter and hypothyroidism. While iodized salt has reduced deficiency in many countries, it remains a concern for those on salt-restricted diets or who avoid processed foods.
