Iodine is an essential micronutrient required for normal thyroid function, growth, and development. Its deficiency is a major cause of preventable mental retardation. In its most severe forms, Iodine Deficiency Disorders (IDDs) can lead to cretinism, stillbirth and miscarriage; even mild deficiency can cause a significant loss of learning ability.
