Iodine is a mineral found in some foods. The body needs iodine to make thyroid hormones. These hormones control the body's metabolism and many other important functions. The body also needs thyroid hormones for proper bone and brain development during pregnancy and infancy.

Why iodine is an essential micronutrient?
Iodine is an essential micronutrient incorporated into thyroid hormones. Although iodine deficiency can lead to a broad spectrum of disorders throughout life, it is most critical in the early stages of development, as the foetal brain is extremely dependent on iodine supply.
Is iodine necessary for life?
Iodine is a vital micronutrient required at all stages of life; fetal life and early childhood being the most critical phases of requirement. Diet is the sole source of iodine, which in turn is dependent upon the iodine content of water and soil.
Is iodine essential for growth?
Share on Pinterest Iodine is essential for growth and brain development. Iodine is central to healthy thyroid function. The thyroid gland uses iodine to make thyroid hormones.
Why is iodine needed for proper brain development?
I is required for the synthesis of thyroid hormones. These hormones, in turn, are required for brain development, which occurs during fetal and early postnatal life.
Why is iodine added to salt?
Iodine (in the form of iodide) is added to table salt to help prevent iodine deficiency. Since the 1980s there have been efforts to have universal salt iodization. This has been an affordable and effective way to combat iodine deficiency around the world, but not all salt contains iodine, however.
Does Himalayan salt have iodine?
Because of this reduced sodium content and presence of trace minerals, the Himalayan salt gets marketed as a healthy alternative to regular salt. Himalayan salt has no added iodine, which may cause hypoactive thyroid in iodine-deficient individuals.
How did ancient humans get iodine?
But before soy and dairy were common food staples, iodine came from the fruits of the sea – shrimp, tuna, shellfish and seaweed, for example. Iodine-rich foods abound in coastal areas and researchers think that the evolution of large human brains and advanced cognition is thanks in part to this key nutrient.
Where is iodine found naturally?
Iodine is naturally present in the ocean and some sea fish and water plants will store it in their tissues. Iodine can be found naturally in air, water and soil. The most important sources of natural iodine are the oceans.
What is the physiological role of iodine?
At present, the only physiologic role known for iodine in the human body is in the synthesis of thyroid hormones by the thyroid gland.
What is the function of iodine solution?
Over-the-counter and prescription forms of iodine solution are often used to prevent infections. The mineral is often added to topical antiseptics and is believed to destroy infectious microorganisms with minimal risk of side effects. Iodine is also used for pre-surgical care.
Does iodine help focus?
NEW YORK (Reuters Health) - Iodine supplements may improve mental function in children with even mild deficiencies in the nutrient, a small study suggests.
Does iodine affect intelligence?
It results in impaired cognitive and motor development which affects a child's performance at school. In adulthood, it affects productivity and the ability to find a job. Iodine-deficient people may forfeit 15 IQ points, and nearly 50 million people suffer from some degree of iodine deficiency-related brain damage.
Where do we use iodine?
Today, iodine has many commercial uses. Iodide salts are used in pharmaceuticals and disinfectants, printing inks and dyes, catalysts, animal feed supplements and photographic chemicals. Iodine is also used to make polarising filters for LCD displays.
Is iodide the same as iodine?
What is iodine? Also called iodide, iodine is a type of mineral that's naturally found in the earth's soil and ocean waters. Many salt water and plant-based foods contain iodine, and this mineral is most-widely available in iodized salt.
What is iodine deficiency called?
Population effects of severe iodine deficiency, termed iodine deficiency disorders (IDDs), include endemic goiter, hypothyroidism, cretinism, decreased fertility rate, increased infant mortality, and mental retardation. Iodine is a chemical element.
