World Iodine Deficiency Day

Global Iodine Deficiency Disorders (IDD) Prevention Day or World Iodine Deficiency Day is observed every year on 21st October. Iodine is an essential element for healthy life. It is a micro- nutrient element essential to human life. A lack of iodine may lead to mental retardation, goiter, or thyroid disease.
