  • important micronutrient for humans
  • a deficiency of the element can cause lowered production of thyroxine (hypothyroidism)
  • enlargement of the thyroid gland (endemic goiter) in adults or cretinism in children.

So, Iodine deficiency affects about two billion people around the world and is the leading preventable cause of mental retardation.

the amount of iodine and the specific iodine compound added to salt varies from country to country. In the United States, the Food and Drug Administration (FDA) recommends [21 CFR 101.9 (c)(8)(iv)] 150 micrograms of iodine per day for both men and women.
