Iodine is an essential element that is required in the production of thyroid hormones however the body does not produce it naturally so it's an essential part of your diet

Some symptoms of iodine deficiency include:

  • Hypothyroidism: a condition where the body does not produce enough thyroid hormones
  • Thyroid goiters which will show as lump in the neck
  • Sensitivity to cold
  • Constipation

This at home urine test is also helpful in determining the effectiveness of iodine supplementation in an individual, as well as tracking treatment progress. It is easy to use and only requires urine collection on a filter strip 2 times a day (first morning and last night void), therefore, eliminating the inconvenient 24-hour collection of urine in a jug.

Collection of urine sample can be done either by dipping the strip in urine collected in a cup or by urinating directly on the strip. The urine-saturated filter strips must be dried overnight and sent to the laboratory for iodine and creatinine analysis. Your test result will be made available in 3 to 5 business days from the date your sample is received.

The comprehensive test report will include a graph showing where your hormone levels fall within set ranges; another graph detailing the symptoms you listed on your self-evaluation form; and individualized details of your hormone evaluation.

Additional Information: 

Iodine is a trace mineral that plays several important functions in the human body, such as controlling the metabolic rate, maintaining the energy levels, maintaining healthy reproductive system, and assisting in the process of programmed cell death. In adults, the recommended daily dietary intake of iodine is 150 micrograms, and 90-120 micrograms in children. For pregnant women, consumption of 200 micrograms per day is required for optimal production of thyroid hormone. The figures are approved by the World Health Organization (WHO), International Council for the Control of Iodine Deficiency Disorders (ICCIDD), UNICEF, Centers for Disease Control (CDC), and other international organizations that study iodine nutritional status of world populations. 

Iodine is typically obtained from what you eat and drink. Among the various sources of iodine include iodized table salt, shellfish, sardines, tuna, oyster, salmon, cod, shrimp, sea bass, kelp, and seaweed. Dairy products also contain iodine, as well as plants grown in iodine-rich soil. 

Goiter is not the only side effect of iodine deficiency. Other health problems that an iodine deficient individual may experience include dry skin, hair loss, fatigue and slowed reflexes. Iodine deficiency is said to be more prevalent in women than in men, and is more common in pregnant women and older children. Pregnant women that are iodine deficient are at greater risk of miscarriage, stillbirths, or giving birth to children with cretinism and severe neurological and developmental defects. 

Iodine excess, on the other hand, can also bring some discomfort and illnesses, such as thyroid underactivity. Although the symptoms of iodine excess are not as severe as iodine deficiency, it's still considered undesirable and should be equally monitored. 

One of the most effective way to keep track of your iodine level is through dried urine testing. At TestCountry, we offer the iodine dried urine test that allows for determination of iodine status based on CDC and WHO guidelines for thyroid sufficiency, as well as extrathyroidal sufficiency. It's convenient and easy to use for both patient and the health care provider.

What is iodine and what does it do?

Iodine is a mineral found in certain foods. The body requires iodine to make thyroid hormones. These hormones control the body’s metabolism and several other essential functions. Also, it is needed for proper bone and brain development during pregnancy and infancy, which means pregnant women and infants need enough iodine.

How much iodine do I need?

Age is one of the determining factors for the amount of iodine you need every day. The average daily recommended amounts are listed below in micrograms (mcg).

What foods provide iodine?

Iodine naturally occurs in some foods and is also added to salt that is labeled as “iodized”. You can get recommended amounts of iodine by eating a variety of foods, including the following:

· Fish (such as cod and tuna), seaweed, shrimp and other seafood, which are generally rich in iodine.

· Dairy products (such as milk, yogurt, andcheese) and products made from whole grains (like breads and cereals), which are the major sources of iodine in American diets.

· Fruits and vegetables, which contain iodine, although the amount depends on the iodine in the soil where they grew and in any fertilizer that was used.

· Iodized salt, which is readily available in the United States and many other countries. Processed foods, however, such as canned soups, almost never contain iodized salt.

What kinds of iodine dietary supplements are available?

Iodine is available in dietary supplements such as potassium iodide or sodium iodide. Many multivitamin -mineral supplements contain iodine. Dietary supplements of iodine-containing kelp (a seaweed) are also available.

Am I getting enough iodine?

Most people in the United States get enough iodine from foods and beverages. However, some groups of people have more trouble in getting sufficient doses of iodine than the others. These include:

· People who don’t use iodized salt, which is one of the most common ways to keep iodine deficiency in check. At present, about 70% of households in the world use iodized salt.

· Pregnant women require 50% more iodine than other women to provide iodine for their baby. Surveys show that many pregnant women in the United States may not get quite enough iodine, although experts do not know whether this affects their babies.

· People living in the regions with iodine-deficient soils eating local produce can lack iodine. This is because these soils produce crops with low levels of iodine. Some of the regions with iodine-poor soil include mountainous areas such as the Alps, the Andes, the Himalayas and also the river valleys in South and Southeast Asia.

· People who get marginal amounts of iodine or those who eat foodstuff containing goitrogens don’t get enough iodine. Goitrogens are in fact, substances that interfere the way the body uses or processes iodine. These are present in certain plant food such as soy , and cruciferous vegetables that include but are not limited to cabbage, broccoli, cauliflower and Brussels sprouts. People living in the USA who get adequate amounts of iodine, eating food containing goitrogens shouldn’t be worrisome.

What happens if I don’t get enough iodine?

Iodine deficiency is uncommon in the United States and Canada. People who don’t get enough iodine can’t make sufficient amounts of the thyroid hormone. This can cause many problems. In pregnant women, severe iodine deficiency can cause permanent harm to the fetus with stunted growth, mental retardation and delayed sexual development. In its less severe forms, iodine deficiency can lead to development of below-average IQ in infants and children and also, decrease adults’ ability to work and think clearly. More often than not, the first sign of iodine deficiency is Goiter, which is the enlarged thyroid gland.

What are some effects of iodine on health?

Scientists are studying iodine in order to understand how it affects general health. The research has shed light on the following pointers:

Fetal and infant development

Pregnant women or breastfeeding mothers require adequate amount of iodine to ensure that their babies grow and develop properly. The source of iodine for breastfed infants is their mother’s breast milk. But it all depends on how much iodine the mother gets. To make adequate amounts of iodine available for proper fetal as well as infant development, a number of national and international groups have recommended that pregnant and breastfeeding women and infants take iodine supplements. In the United States and Canada, the American Thyroid Association recommends taking of prenatal vitamin /mineral supplements containing iodine (150 mcg/day). However, only about half the prenatal multivitamins sold in the United States contain iodine.

Cognitive function during childhood

Severe iodine deficiency during childhood has harmful side effects, especially on the development of the brain and the nervous system. Although the effects of mild iodine deficiency during childhood are difficult to measure, but it has the potential to cause subtle problems with neurological development.

Providing iodine supplements to children with mild iodine deficiency can significantly improve their reasoning abilities as well as their overall cognitive function. For the children who live in the iodine-deficient areas, iodine supplements are helpful for improving their physical and mental development. However, more study is needed to fully understand the effects of mild iodine deficiency and of the iodine supplements on the cognitive function.

Fibrocystic breast disease

Very high doses of iodine supplement can assist in reducing the pain and many other symptoms of fibrocystic breast disease. However, this needs to be confirmed with more studies.  Check with your health care provider before taking iodine for this condition, especially because iodine can be unsafe at high doses.

Radiation-induced thyroid cancer

Nuclear accidents can lead to the release of radioactive iodine in the environment. This increases the risk of thyroid cancer in people exposed to it and it affects mainly those who are iodine-deficient. Children are especially vulnerable to it. The U.S. Food and Drug Administration has approved potassium iodide as a thyroid-blocking agent for lessening the risk of thyroid cancer during radiation emergencies.

Can iodine be harmful?

Yes, if you get too much. Getting high levels of iodine can cause a few of the similar symptoms such as those in iodine deficiency and goiter (an enlarged thyroid gland). High iodine intakes can also cause thyroid gland inflammation and thyroid cancer. A large dose of iodine (several grams, for example) leads to the burning of the mouth, throat, and stomach; fever; stomach pain; nausea ; vomiting; diarrhea ; weak pulse; and coma.

The upper limits for iodine are listed below but it doesn’t apply to people taking iodine for medical reasons under the care of a doctor.

Not established

Children 1–3 years:

200 mcg

Children 4–8 years:

300 mcg

Children 9–13 years:

600 mcg

Teens 14–18 years:

900 mcg

Adults:

Are there any interactions with iodine that I should know about?

Yes. Iodine supplements can interact or interfere with your ongoing medications prescribed by your physician or over-the-counter medicines. Here are some examples:

· Iodine supplements can interact with anti-thyroid medications like methimazole (Tapazole®), which is used to treat hyperthyroidism. When you take high doses of iodine with these medications, your body will begin producing too little thyroid hormone.

· When you take potassium iodide with medications for high blood pressure known as ACE inhibitors, there are chances that it will raise the amount of potassium in the blood to an unsafe level. ACE inhibitors include benazepril (Lotensin®), lisinopril (Prinivil® and Zestril®), and fosinopril (Monopril®).

· The amount of potassium in your blood can also get too high if you take potassium iodide with potassium-sparing diuretics , such as spironolactone (Aldactone®) and amiloride (Midamor®).

Tell your doctor, pharmacist , and other health care providers about any dietary supplements and medicines that you take. They’ll be able to tell you whether it will interact or interfere with your regular prescription  or over-the-counter medicines. Also, they’ll be able to tell you whether they will interfere with how your body absorbs , uses, or breaks down nutrients.
