Iodine is an essential mineral. Your body needs it to function properly but cannot make it on its own. Instead, you need to consume it.
It’s a trace element, or a relatively small percentage of the body’s tissue. That means your body only needs a small amount of it.
Around 70 to 80 percent of iodine is found in the thyroid gland in the neck. The rest is in the blood, the muscles, the ovaries, and other parts of the body.
Iodine is essential for thyroid functioning. Your thyroid needs it to produce hormones essential for metabolism.
A deficiency can lead to hypothyroidism, meaning that your thyroid isn’t working as well as it should, and it can lead to issues such as fatigue, joint pain, and fertility problems.
The mineral is also important for women who are pregnant and young children, because it plays a role in proper bone and brain development.
It’s mainly present in foods such as fish, seaweed, and dairy. It’s widely available in the form of iodized salt.
It also exists in the Earth’s soil, but the content varies from one area to the next. As such, the iodine content of produce varies.
Iodine is found in foods, but amounts can be hard to identify. Iodized salt is the main source of this mineral in the United States.
Most people need to regularly use salt that is enriched with iodine in order to get enough in their diet.
