Iodine is an essential component of the well-known thyroid hormone, thyroxine, found in the thyroid gland in which most of the iodine in our body resides. This hormone is responsible for regulating our metabolism within our entire body. Iodine deficiency can cause a condition known as goitre, in which the thyroid gland tends to swell.

Iodine also not only contributes to energy metabolism, but also skin, the nervous system and even cognition within our brains.
