Iodine is an essential trace element crucial for the proper functioning of the thyroid gland. The recommended daily allowance for iodine varies by age and life stage. It plays a pivotal role in thyroid hormone production, which regulates metabolism and supports overall growth and development. Iodine deficiency can lead to thyroid disorders, including goiter. On the other hand, excessive iodine intake can have adverse effects. Recognizing the importance of iodine in thyroid health and its impact on metabolism underscores its role in maintaining overall well-being and proper thyroid function.
