Iodine: what is it?
Iodine is an essential nutrient for humans. It’s important for growth, development and good health, but we only need a small amount of it.
Iodine occurs naturally in the sea and in some soils.
Iodine is also found in marine life (including fish, prawns and seaweed), some plants grown in iodine-rich soil, and in the products of animals that have grazed on soil with iodine in it.
Iodine is added to some foods, like salt and commercially baked bread.
Why we need iodine
Our thyroid glands need iodine to produce the hormones that control metabolism, growth and development.
