Iodine

Thyroid

Iodine is an important component of the thyroid hormones thyroxine (T4) and triiodothyronine (T3). Thyroid hormones regulate many important biochemical reactions, including protein synthesis and enzymatic activity, and are critical determinants of metabolic activity. They are also essential for proper development of skeleton and central nervous system in foetuses and infants.
