Iodine is one of eight essential trace minerals. It's called essential because our body doesn't make it. We have to get it from the foods we eat. Iodine is an essential part of the thyroid horomones thyroxine (T4) and triiodothryonine (T3), which are used by the body to regulate many important biochemical reactions. Think "hormones." Iodine is a must for balance.
Iodine is considered the "anchor" mineral. It is needed by the body for all other minerals to be absorbed.
