It is estimated that more than 90% of the U.S. population is iodine deficient, and up to 74% is severely deficient based on clinical findings and national studies (NHANES I – 1974 and NHANES II – 2000) by the Centers for Disease Control and Prevention (CDC) designed to assess the health and nutritional status of adults and children in the United States.

Iodine is involved in immunity, metabolism, energy production, fetal and early childhood cognitive development, hormone production, the conversion of carcinogenic estrogen and progesterone hormone metabolites, heavy metal, radiation detoxification, and more.

Then you, like 74% – 90% of Americans, are likely deficient in iodine. Iodine is needed to make thyroid hormones. These are also symptoms of hypothyroidism.. When patients take thyroid medications for hypothyroidism, their need for iodine throughout the body (not just for making thyroid hormones) rises due to improved metabolic processes. 

Did you know?

Chlorinated water, bakery products, flame retardants, and other dietary and environmental issues reduce our body’s ability to use iodine. Chlorine, fluorine, and bromine compete with iodine in the body. On the periodic table of elements, iodine is in a group called the halogens. Fluorine, chlorine, and bromine are in the same halogen family. Iodine is lower on the table, which means that the other elements in this group are much more reactive. They will take binding sites first and even strongly displace iodine that is already bound.


When this occurs, the thyroid hormone does not function as it does when iodine is in place. It creates a state of thyroid deficiency called secondary hypothyroidism. Even though you may have adequate thyroid hormone levels according to test results, if it is brominated (meaning the iodine-binding sites have bromine instead of iodine), then the thyroid hormones do not work like they should! Hypothyroidism leads to many serious health issues, including obesity.

Why is this important? Chlorine and fluorine are in our bathing water, drinking water, pools and hot tubs. Bakery products and carpets are now very high in bromine. Fluoride is in our toothpaste. These elements – fluorine, chlorine, and bromine – are toxic to our bodies. Fortunately, iodine supplementation can help increase urinary excretion of fluorine, chlorine, and bromine.

Lugol's iodine holistic treatment solution provides both forms of iodine and iodide. Both types of iodine are needed in the body — breast and prostate tissue prefer iodine, and thyroid tissues prefer iodide — and both types are available with a Lugol's solution. Various other tissues and organs are designed to concentrate large amounts of iodine and iodide necessary for their normal structure and function. Conversely,
low iodine levels are associated with autoimmune thyroid disease, breast cancer, thyroid cancer, goiter, and fibromyalgia, as well as cysts and nodules of the breasts, thyroid, and ovaries.

Other types of iodine supplements have not been shown to provide this type of tissue-specific support.

Find out how many ways iodine impacts your health:

Supercharges Energy Production and Fires Up the Metabolism

  • Iodine is required to synthesize thyroid hormones. These hormones regulate metabolism, oxygenation, and energy production. When we are iodine deficient, we lack energy and can feel sluggish.

  • Patients taking thyroid hormones may also need to take an iodine supplement. All the cells of the body use iodine, and thyroid hormones can increase the body’s need for iodine. Disorders that involve iodine deficiencies may worsen or become more prevalent, such as breast, prostate, and thyroid cancers.

Facilitates Weight Management

  • Iodine helps prevent metabolic weight gain and helps maintain healthier weight and energy levels. Iodine can fire up the metabolism to burn calories more easily.

Balances Hormones and Reduces Cancer

  • Iodine promotes hormone balance and production of all the body’s hormones – not just thyroid hormones. Balance is key for disease prevention, as well as an overall sense of well-being.

  • Iodine helps regulate hormone production and balance estrogen production in the ovaries in females and adrenal tissues in men that can stimulate the development and progression of hormone-related cancers such as breast, ovarian, uterine, cervical, and prostate cancers.

  • Estrogen dominance in both men and women is dramatically increased in iodine-deficient, hypothyroid states. Estrogen dominance also appears to be a significant risk factor in the development of hormone-related cancers.

  • Incidence of hormone-related cancers (breast, ovarian, uterine, prostate, and cervical) as well as stomach, lung, esophagus, thyroid, and throat cancer are markedly increased in iodine-deficient patients.

  • Incidence of goiter (enlargement of the thyroid gland because of iodine deficiency) and breast and prostate cancers have a direct relationship with iodine levels. Two studies done in Iceland and Japan – populations with high iodine intake – have shown a much lower incidence of breast and prostate cancers and goiter compared to other populations.

  • Iodine helps prevent fibrocystic breast diseases and is used successfully to treat fibrocystic diseases such as uterine fibroids and ovarian cysts.

Cardiovascular Health

  • Iodine supplementation can naturally reduce the amount of circulating cholesterol by helping to address one of the underlying causes of high-cholesterol: hormone imbalances and deficiencies (cholesterol is the precursor to sex steroidal hormones and adrenal hormones).

  • Iodine sufficiency can help prevent or alleviate symptoms of metabolic syndrome starting with the hallmark: hypothyroidism. Clinical studies show a direct correlation between iodine deficiency and the cascade of other diseases related to metabolic syndrome such as diabetes, heart disease, and cancer.


Strengthens the Immune System

  • Iodine destroys viruses, bacteria, pathogens, molds, fungi, parasites, and malaria on contact.

  • Iodine helps prevent urinary tract infections (UTIs).

  • Iodine treats and helps prevent h. Pylori – a bacterial infection of the stomach that has been connected with ulcers and gastric cancer.


Increases Mental Focus, Clarity, and Memory

  • Children born to women with higher iodine levels showed a decrease in SIDS and a higher childhood survival rate.

  • Iodine can make us smarter. It promotes sharp thinking, mental focus, cognitive functioning, and helps eliminate brain fog in adults.

Supports Normal Fetal and Childhood Development

  • Iodine makes children smarter. Iodine is essential for normal growth and development of children. Pregnant women who are iodine deficient have children with a greater risk of mental-development issues. A study showed a 15-point reduction in children’s IQs when pregnant women were iodine deficient.

  • Iodine helps support proper fetal development and growth along with speech and hearing development.

  • The percentage of pregnant women with iodine deficiency increased 690% between the NHANES I (1974) and NHANES ii (2000) studies. It is well-known that a low maternal iodine level in fetal development is associated with higher levels of cretinism, mental development issues, autism, ADD, SIDS, ALS, and other myelin disorders.


Supports Pregnancy and Reproductive Health

  • Adequate iodine levels can also be important in the treatment of infertility, because iodine is essential for healthy hormone balance.

  • Pregnant women who have adequate iodine are also less likely to experience high blood pressure during pregnancy.

  • Iodine can help prevent and treat endometriosis, uterine fibroids, and ovarian cysts related to hormonal imbalance and dysfunction.


Improves Fibromyalgia and Migraine

  • Iodine helps reduce fibromyalgia symptoms.

  • Iodine supplementation helps resolve migraine headaches and other types of chronic headaches for many patients.


Supports Heavy metal and halide detoxification

  • Adequate iodine levels reduce the amount of halide toxicity in the body from fluoride (in water), chlorine (in water), and bromine (in bread preservatives and carpet flame retardants).

  • Iodine levels can be affected by halides. Halides successfully compete for iodine’s binding sites on cells and hormones, rendering them ineffective. For example, thyroid hormones may contain atoms of bromine rather than iodine, as they should. This results in inactive thyroid hormones. Some practitioners and patients are perplexed at “normal” thyroid hormone test results with hypothyroid symptoms.

  • Iodine helps prevent lead and other metals from being stored in the body.


Provides Radioactivity Protection

  • Iodine helps prevent effects of radiation exposure from the use of cordless phones and cell phones.

  • Normal iodine levels can protect the thyroid and the rest of the body from radioactivity generated by nuclear accidents, such as the radiation drift from the Fukushima disaster that crossed the Pacific and is still detected on the U.S. mainland.


Supports Healthy Nails, Hair, and Teeth

  • Iodine is essential to the formation of healthy skin, teeth, and shiny hair.

  • Iodine deficiency results in hair loss.

  • Iodine supports hair growth and follicle strength.
