Iodine
Support for the thyroid, cognitive function, and energy metabolism
Iodine is an essential mineral that plays an important role in several bodily functions. It contributes to the normal production of thyroid hormones and the normal functioning of the thyroid. These thyroid hormones regulate metabolism and support the growth and development of the body.
Additionally, iodine contributes to normal cognitive function, meaning it is involved in memory, learning ability, concentration, and problem-solving skills. This is especially important during periods of mental exertion.
Iodine also contributes to a normal energy-producing metabolism, helping to convert nutrients into usable energy.
Sources of Iodine
Iodine occurs naturally in foods from the sea and certain fortified products.
Good sources of iodine include:
- Seafood such as fish (cod, salmon, tuna) and shellfish.
- Seaweed, including kelp and nori, which contain very high concentrations of iodine.
- Dairy products such as milk, cheese, and yoghurt, depending on the iodine content of the livestock feed.
- Eggs, especially the yolk, which contains a small amount of iodine.
- Iodized salt, which is added to table salt in many countries to promote sufficient iodine intake.
Since iodine is not found in large quantities in plant-based foods, it can be difficult for vegetarians and vegans to get enough without fortified foods or supplements.
Forms and Absorption
Iodine is primarily absorbed in the form of iodide, which is absorbed into the blood through the small intestine and transported to the thyroid. Here, it is used for the production of thyroid hormones.
The absorption of iodine can be affected by certain nutrients, such as goitrogens (substances found in soy and cruciferous vegetables), which in large quantities can interfere with iodine absorption.
For optimal iodine status, a varied diet with sufficient iodine-containing foods is important.
