How Much Iodine is in an Egg?

One of the most common questions is how much Iodine is in an egg? While other sources of Iodine are more concentrated, eggs are a good source of Iodine because they provide a single serving of Iodine, which is around 16 percent of your daily recommended dietary allowance. Chicken eggs contain the most Iodine, duck eggs are slightly larger and oranger than chicken eggs, and Quail eggs are the smallest.


A study used an ICP Mass Spectrometer to examine the iodine level in chicken eggs. Iodine was the standard, and an internal measure of 10 ng mL-1 indium was utilized for calibration. More remarkable, three times less Iodine was produced from eggs with lower iodine contents than from eggs with higher iodine contents. Fifteen samples of each of the five food items—golden thread (fish), prawn, kelp, and egg—were used in the experiment. The samples were prepared with various techniques and at boiling temperatures, and the cooked egg samples did not take the same time. Additionally, the egg samples were stir-fried without oil and analyzed with tap water. The results of these tests were used to assess whether there was a substantial difference between the raw and cooked samples.

Egg Nutrition Facts

Egg Nutrition facts


Females of a wide range of species, including birds, reptiles, amphibians, a few mammals, and fish, lay eggs; many of these have been consumed by humans for countless generations. A protective eggshell, albumen (egg white), and vitellus (egg yolk), all enclosed in a variety of thin membranes, make up the components of bird and reptile eggs. Eggs from chickens are the most widely consumed, and eggs from other poultry, such as duck and quail, are also destroyed. Both roe and caviar are terms for fish eggs.

Both egg yolks and entire eggs are frequently used in cooking and provide large amounts of protein and choline. Previously, the United States Department of Agriculture classified eggs as meats within the Food Guide Pyramid due to their high protein content. The cholesterol level, salmonella contamination, and allergy to egg proteins are some potential health risks associated with eggs despite their nutritional value.

What is Iodine?

Iodine is a sort of mineral that is naturally present in soil and ocean waters. It is also known as iodide. Iodine is a mineral found in various plant-based foods and salts but is most commonly found in iodized salt. Iodine must be consumed in sufficient amounts in the diet. It controls hormones, fetal growth, and other things. If you don’ton’t have enough Iodine, your doctor might suggest supplements. Never take supplements without first consulting your doctor. Continue reading to discover iodine’s benefits and drawbacks and the recommended daily intake for each age group.

How Much Iodine is in an Egg?

Iodine can also be found in eggs. One entire egg offers a lean amount of protein, healthy fats, and a variety of vitamins and minerals for less than 100 calories. But the yolk is where most minerals, like Iodine, are found.

Iodine is a mineral added to chicken feed, making egg yolks a good source of Iodine. However, because the amount of Iodine in chicken feed can change, so can the amount in eggs. One large egg typically contains 24 mcg of Iodine, 16% of the recommended daily amount. Iodine is a crucial mineral for your thyroid to generate hormones that control your body’s metabolic rate. Additionally, it aids in maintaining healthy skin and proper brain growth and cognitive performance.

Iodine deficiency can be reasonably prevalent and result in several medical issues, including thyroid gland enlargement and persistent weariness. Eating just two eggs daily can consume 32 percent of the required iodine intake. Many of us frequently buy egg whites to reduce cholesterol, although Iodine is found in the yellow yolk. One-third of your daily demands can be satisfied by two scrambled eggs. By breakfast is over, you will have essentially reached your iodine goal if you add some table salt to your scramble.

What are the Health Effects of Consuming Iodine?

Iodine is regarded as a mineral that our bodies must have. It’sIt’scial throughout pregnancy, and exposure, when a woman is still in the womb, may even help shield her from developing some illnesses later on.

Some of the most significant applications and their health benefits are listed below.

Promoting Thyroid Health

For the health of the thyroid, Iodine is essential. Your thyroid gland, situated near the base of your front neck, aids in controlling the production of hormones. These hormones govern your metabolism, heart health, and other factors. Your thyroid absorbs Iodine in trace amounts to generate thyroid hormones. Thyroid hormone synthesis may be reduced in the absence of Iodine.

A condition known as hypothyroidism can result from a “low” or”underactive thyroid gland. Low iodine levels in the United States typically have little effect on thyroid health because Iodine is widely available in western diets. Saltwater fish, fortified meals, and dairy products can all help you meet your iodine needs. Plant foods that grow in naturally high Iodine soil also contain Iodine. You can also obtain the mineral by using iodized salt for seasoning your meal.

Reducing Risk for Some Goiters

An enlarged thyroid gland is known as a goiter. Either hypothyroidism or hyperthyroidism can cause your thyroid to grow. An overactive thyroid gland is known as hyperthyroidism. Enlargement of the thyroid gland can also result from non-cancerous thyroid nodules (cysts).

Sometimes iodine deficiency causes a goiter to grow as a direct result. Although it is less common in the United States and other nations with access to iodine-rich diets, this is the most common cause of goiter worldwide. Iodine-rich foods or supplements can be added to the diet to treat iodine-induced goiters.

Managing Overactive Thyroid Gland

To treat an overactive thyroid gland, your doctor may advise using radioactive Iodine, a unique kind of Iodine. This drug, sometimes known as radioiodine, is consumed orally, and it helps to reduce excessive thyroid hormone production by destroying extra thyroid cells.

The danger of radioactive Iodine is that it may kill off an excessive number of thyroid cells, resulting in less hormone production, which could cause hypothyroidism. This is why radioactive Iodine is typically only suggested when other anti-thyroid medications have failed. Iodine supplements and radioactive Iodine are not the same, and iodine supplements are never advised for hyperthyroidism.

Treating Thyroid Cancer

Additionally, radioiodine might be used to treat thyroid cancer, and it functions very similarly to hyperthyroid therapy. Orally administered radioactive Iodine kills thyroid cells, including malignant ones. It may be utilized as a treatment to guarantee that all malignant cells have been eradicated from the body following thyroid surgery. According to the American Cancer Society, treatments with radioactive Iodine considerably increase patients surviving thyroid cancer.

Neurodevelopment During Pregnancy

When pregnant, you require more Iodine, and this is because iodine consumption during pregnancy has been associated with fetal brain development. According to one review, children whose birth mothers experienced an iodine deficiency while pregnant were more likely to have lower IQs and other intellectual disabilities as adults.

The daily intake advised Iodine for pregnant women from a reliable source contains 220 mcg. Adults who are not pregnant are advised to take 150 mcg each day. Ask your doctor about iodine supplements if you’re, especially if your prenatal vitamin is deficient in Iodine (many do not). You can also need iodine supplements if you don’t have enough of the mineral.

If breastfeeding, you’ll need to monitor your iodine consumption. Iodine intake of 290 mcg per day is advised while nursing, and this is because your nursing infant receives the Iodine you get through your diet and supplements through breast milk. Infants must have 110 mcg daily until they are six months old because this is a critical time for brain development.

Improving Cognitive Function

Iodine’sne’srological advantages during pregnancy may also contribute to children’s brain development. Additionally, there is a lower chance of intellectual handicap. Your child probably consumes all the Iodine they require through diet, but if you have any concerns about this, consult a pediatrician.

What are the Health Risks of Iodine?

Although Iodine has a lot of health benefits and uses but it has some adverse effects also:

  • Iodine toxicity can result from consuming too much Iodine. Depending on how much you are down, you may experience various symptoms, from disorientation and a weak pulse to nausea and vomiting.
  • Sometimes, consuming too much Iodine can cause hyperthyroidism or an overactive thyroid.
  • While ensuring you consume enough Iodine can help prevent goiters from developing, too much Iodine may cause them to form.
  • High amounts of Iodine in your diet may increase thyroid inflammation and cancer risk.
  • Iodine supplements may interact with certain medications. Taking supplements while also taking anti-thyroid drugs such as methimazole may cause your body to produce too little thyroid hormone.
  • Potassium iodide supplements with ACE inhibitors may also cause too much potassium in your blood, leading to hyperkalemia. Hyperkalemia can lead to serious heart-related problems.

How Much do you Need?


The amount of Iodine you need varies on your sex and age:

  • Birth to 6 months: 110 micrograms
  • Seven months to 1 year: 130 micrograms
  • Children up to 8 years: 90 micrograms
  • Children 9 to 13: 120 micrograms
  • Teens and adults: 150 micrograms
  • Women who are pregnant: 220 micrograms
  • Women who are breastfeeding: 290 micrograms

In general, most people get all the Iodine they need from food. Some of the best sources include:

  • Seaweed
  • Fish and shellfish
  • Dairy
  • Fortified foods
  • Iodized salt

If you think you don’t have enough Iodine in your diet, speak with your doctor. Your doctor can test your levels and determine if you need a supplement. While most accessories are available over the counter, a doctor may prescribe a more potent version in more severe cases.


Iodine is an essential mineral; your body needs it to function correctly but cannot make it independently. Instead, it would be best if you consumed it.

Most people get all the Iodine they need from food. It’sIt’snly present in foods such as fish, seaweed, dairy, and eggs. It’sIt’sely available in the form of iodized salt. It also exists in the Earth’sth’sl, but the content varies from one area to the next. As such, the iodine content of produce varies.

Iodine is essential for thyroid functioning; your thyroid needs it to produce hormones necessary for metabolism. A deficiency can lead to hypothyroidism, meaning that your thyroid isn’t as well as it should be, and it can lead to issues such as fatigue, joint pain, and fertility problems.
