Overview

Iodine is an essential trace mineral that is crucial for human health, primarily known for its role in thyroid hormone production. The body does not produce iodine, so it must be obtained through diet. Thyroid hormones, namely thyroxine (T4) and triiodothyronine (T3), regulate many important biochemical reactions, including protein synthesis, enzymatic activity, and metabolic rate. They are also critical for skeletal and central nervous system development in fetuses and infants (NIH ODS, Iodine Fact Sheet for Health Professionals). Around 70-80% of the body's iodine is found in the thyroid gland. Iodine deficiency can lead to a range of health issues, including goiter (enlargement of the thyroid gland) and hypothyroidism. Globally, iodine deficiency is a significant public health problem, particularly in regions where dietary intake is low (World Health Organization). As a result, many countries have implemented universal salt iodization programs to ensure adequate intake. Excess iodine intake can also be detrimental, leading to thyroid dysfunction, including both hypothyroidism and hyperthyroidism, highlighting the importance of maintaining an appropriate balance.
