Iodine is an essential element for normal growth and brain development. It is required for the body's production of thyroid hormones, which influence metabolism and are vital for the development and function of the brain, nerves, and bones. While iodine is naturally found in the sea and some soils, it is also added to certain foods, such as iodized salt and, in some countries, commercial bread. A healthy diet should include adequate iodine, but in cases of deficiency, supplements may be recommended, especially for pregnant and breastfeeding women. However, excessive iodine intake can be harmful, particularly for those with thyroid conditions, so it is important to consult a doctor before taking supplements.

Iodine deficiency risks
Iodine is an important trace mineral that is essential for normal growth and the development of the brain. It is required by the body in very small amounts. Iodine deficiency can cause several health risks, especially in unborn and newborn babies, and is the world's number one cause of preventable intellectual disability in children.
Iodine deficiency is the most common cause of thyroid disease, specifically hypothyroidism (underactive thyroid). When the body does not get enough iodine, the thyroid gland enlarges to trap more iodine from the bloodstream to make thyroid hormones. This enlargement of the thyroid gland is called a goitre. The thyroid hormones influence metabolism and are essential for the development and function of the brain, nerves, and bones. Iodine deficiency can lead to insufficient production of thyroid hormones, which can adversely affect the muscles, heart, liver, kidneys, and the developing brain. This results in a series of functional and developmental abnormalities collectively referred to as Iodine Deficiency Disorders (IDD). IDD includes mental developmental problems in children, such as impaired reproductive functions and lowered IQ levels.
In severe cases of iodine deficiency, individuals may experience brain damage and irreversible mental retardation, ranging from mild intellectual blunting to frank cretinism, which includes gross mental retardation, deaf-mutism, short stature, and various other defects. Iodine deficiency during pregnancy can also affect the fetus, causing impaired synthesis of thyroid hormones and increasing the risk of intellectual disability in the baby.
Iodine deficiency is usually treated by consuming more iodine-rich foods or iodised salt, and in some cases, taking iodine supplements. Good sources of iodine include fortified bread, seafood, and seaweed. However, it is important to consult a doctor before taking iodine supplements, as too much iodine can also be harmful, especially for those with underlying thyroid disorders.

Iodine-rich foods
Iodine is a trace mineral that is generally found in seafood. It is an essential micronutrient, which means your body needs it to function properly. Your body uses iodine to facilitate several important body processes. For instance, iodine is critical for your body's thyroid hormone production.
Since few food sources are rich in iodine, many people around the world are at risk of developing a deficiency. This is why iodine is frequently added to other foods as a fortification. In places where iodine fortification is common, iodine deficiency is rare. However, nearly one-third of the world is still at risk of iodine deficiency.
- Seafood: Seafood is generally a good source of iodine. This includes fish such as tuna, cod, and shrimp, as well as seaweed.
- Dairy: Dairy products like milk and yoghurt are good sources of iodine.
- Eggs: A single hard-boiled egg provides about 26 mcg of iodine.
- Fortified foods: In some places, iodine is added to common foods like bread and table salt to increase iodine intake. In Australia, for example, all commercial bread products except organic bread contain iodised salt.
- Beans: Beans are another source of iodine, although the amount they contain may vary.
- Fruit: Certain fruits contain iodine, although the specific types are not mentioned in my sources.

Iodine supplements
Iodine is an essential nutrient that helps your body make proteins and build bones and nerves. Most people should be able to get all the iodine they need by eating a varied and balanced diet. Good sources of iodine include seafood, seaweed, eggs, milk, dairy products, and iodised salt. Since 2009, commercial bread in Australia has been fortified with iodine.
However, if you are following a strict vegan diet or are unable to consume iodine-rich foods, you may need to take an iodine supplement. Iodine supplements are also recommended for pregnant and breastfeeding women, as iodine deficiency can affect a baby's growth and development. It is important to note that too much iodine can be harmful, especially if you have a thyroid disorder. Therefore, it is recommended to consult a doctor or healthcare professional before taking iodine supplements.
In addition to supplements, iodine can also be used topically to treat certain conditions. For example, iodine eye drops can reduce the risk of pink eye in newborns and adults. Iodine can also be used to treat foot ulcers in people with diabetes and to prevent swelling of the uterus during a cesarean delivery.

Thyroid health
Iodine is a mineral that is essential for normal growth and development. It is not produced by the body and must be obtained through food or supplements. Iodine is necessary for the production of thyroid hormones, which help regulate metabolism, energy use, and brain and bone development. A healthy diet should include adequate iodine, but too much can be harmful, especially for those with thyroid disorders.
Iodine deficiency is a common cause of thyroid problems and can lead to an underactive thyroid (hypothyroidism) or an overactive thyroid (hyperthyroidism). Symptoms of hypothyroidism include fatigue, weight gain, intolerance to cold, infertility, puffy skin, hoarseness, dry skin, and hair loss. Iodine deficiency is rare in the United States but is prevalent in developing countries and certain regions of Australia. It occurs when iodine intake is insufficient, often due to limited access to seafood, dairy, or iodized salt.
To prevent iodine deficiency, one should include iodine-rich foods in their diet. Good sources of iodine include seafood, such as cod and tuna, shrimp, and seaweed, as well as dairy products and iodized salt. Bread made with iodized salt is also a common source of iodine in Australia. Pregnant and breastfeeding women have higher iodine requirements to support their child's development and should consult a doctor for personalized advice.
In some cases, iodine supplements may be recommended, especially during pregnancy or when iodine deficiency is diagnosed. However, it is crucial to consult a healthcare provider before taking supplements, as excessive iodine intake can be harmful, especially for individuals with thyroid conditions or those taking certain medications.

Pregnancy and breastfeeding
Iodine is essential for the production of maternal and fetal thyroid hormones, which regulate the development of the fetal brain and nervous system. Iodine also regulates metabolism, the rate at which the body uses energy. It is critical to fetal health and brain development, and a deficiency during pregnancy has been linked to an increased risk of miscarriage, preterm delivery, and stillbirth.
Pregnant women need more iodine than usual. The Recommended Dietary Allowance (RDA) for iodine is between 220 micrograms (mcg) and 290 mcg during pregnancy, according to some sources. However, the safe upper limit in pregnancy is uncertain because the fetal thyroid is vulnerable to iodine excess. Very high levels of iodine in the body can cause high levels of thyroid hormone (hyperthyroidism), which can lead to medical problems for both the pregnant person and the fetus.
Pregnant women should ensure they are getting enough iodine through their diet or supplements. Iodine is found in dairy products, eggs, and seafood. It is also present in iodized salt, which is used in about half of all table salt to prevent deficiencies. Prenatal vitamins may also contain iodine, but not all do. The National Institutes of Health's Office of Dietary Supplements recommends that pregnant women get 220 mcg of iodine per day.
During breastfeeding, the RDA for iodine increases to 290 mcg daily. This is because babies receive iodine from their mother's breast milk, and it is important that they get enough. The American Thyroid Association and the American Academy of Pediatrics recommend that breastfeeding women take a multivitamin or prenatal supplement containing 150 mcg of iodine every day. It is not recommended to get more than 500 mcg to 1100 mcg of iodine per day while breastfeeding, as this can cause problems with the baby's thyroid gland.
