Iodine, a critical mineral in the prevention of cancer, has been used in one form or another for centuries. First as medicine (for everything from breast cancer to syphilis) and consumed in the form of seaweed, and eventually added to bread. Then, in 1948, iodine was suddenly thought of as dangerous and was removed from medical arsenals – as well as from our food in the 1970s.
Our politicians suggested that people could get trace amounts of iodine in iodized salt, but then two things happened. First, recommendations were made to reduce sodium intake, and second, few realized that the iodine in salt evaporates as soon as the package is opened, rendering it useless.
Ironically, just as iodine was removed from our bread, the iodine-blocking element, bromine, was added to flour. Bromine chemicals were then added not only to our bread and flour, but also to mattresses (as a fire retardant), clothing, and other consumer products.
The problem was exacerbated further as pesticides and food additives were increasingly allowed to be used in our food supply — chemicals that interfere with iodine absorption. It’s no wonder that almost everyone has low iodine today.
Iodine deficiency is, to some extent, an error of politics. However, it has become even more prevalent with the ever-increasing presence of xenoestrogens (chemical estrogens found in many personal and home care products and in air pollution) that not only poison the body, but contribute to hormone imbalance and estrogen dominance.
Add that to the fact that estrogen interferes with the absorption of iodine, and it’s clear to see how iodine has been practically eliminated from our cancer-prevention toolkit.
Iodine Deficiency and Cancer
Iodine consumption – which has plummeted 50 percent since the 1970s – is known for its connection to thyroid health. It is less known that other tissues also require large amounts of iodine, namely the breasts, pancreas, stomach, brain, and thymus.
A deficiency of iodine has been found to influence the occurrence of many cancers, especially stomach and breast cancers. Max Gerson, MD, one of the most famous alternative cancer doctors, believed that iodine is essential for the treatment of cancer.
In Turkey (the country), gastric cancers are most common in areas where iodine deficiency is high. Increased iodine intake over the past several years has been strongly correlated with a reduction in stomach cancers.
Many researchers have attributed the low rate of breast cancer in Japan to high dietary iodine (and selenium). Breast cancer cells need iodine to facilitate cell death and suppress tumor growth.
In 2008, Bernard A. Eskin, MD, explained how iodine actually alters gene expression in breast cancer cells, including the function of programmed cell death. Iodine was also found to decrease estrogen responsive genes.
Low iodine increases circulating estrogen levels, and given that estrogen inhibits iodine absorption, this is especially problematic. Iodine deficiency also makes breasts more susceptible to carcinogenic action, promoting the growth of tumors.
Michael B. Schachter, MD, says, “Iodine may be needed in individualized doses to improve thyroid function, immune function, and the optimal functioning of all the cells in the body; several associated nutrients need to be given including vitamin C, selenium, magnesium, unrefined salt, and sufficient water; these help to prevent strong detoxification reactions as a result of the release of bromine from the tissues when iodine is given in milligram quantities. These higher milligram doses rather than microgram doses help to enhance anti-cancer functions in most if not all cancers, but certainly in cancers of the thyroid, breast, ovary, and prostate.”
Iodine has also been found to:
- alter gene expression in breast cancer cells and facilitate cell death.
- be stronger than a chemotherapeutic agent widely used to treat human breast cancer.
- reduce risk of stomach and breast cancer, and has been used in the remission of lung cancer.
- support healthy immune function and regulate the stress hormone cortisol.
How to Test for Low Iodine
The symptoms of iodine deficiency are varied and iodine testing is rarely part of a routine exam. But given the high rate of deficiency, testing can and should be requested. Here are some possible iodine testing methods:
- A random urine test ordered by a physician is a good place to start.
- The iodine patch test refers to painting a two-inch square of tincture of iodine or Lugol’s Iodine on the body and watching to see how long the orange square takes to fade. However, this test is not considered to be reliable or conclusive.
- The gold standard is the 24 Hour Iodine Loading Test, which can be done with a doctor or via online testing at Hakala Labs and others.
You can get iodine from some foods, with seaweed being the highest source. However, there can be some dangers with seaweed due to contamination from polluted water or radioactivity from Fukushima. Plus, if you need an exact amount, iodine content will vary.
Kelp supplements are an option if you can get a clean source that is not contaminated. Good supplements for iodine are Isodoral and IodoRx, both of which are available over the counter at health foods stores and online. Dr. Edward Group (interviewed in the TTAC docu-series) recommends an iodine supplement called Detoxadine.
A Special Note If You Are on a Therapeutic Iodine Protocol
According to David Brownstein, MD, and other iodine researchers, those on a high-dose iodine protocol (12.5 mg – 50 mg/day) may need a daily companion dose of magnesium as high as 1200 mg, which would be best derived at least in part transdermally. Other companion nutrients (a name coined by Lynne Farrow, author of The Iodine Crisis) are selenium, vitamin C, riboflavin, niacin, and unrefined salt such as Celtic sea salt, Himalayan, and Redmonds Real Salt. These nutrients will boost absorption and help prevent side effects from the protocol such as headaches and fatigue.
If you are considering adding iodine supplemention to your personal health regimen, it is always advisable to consult with a qualified health practitioner who can guide you on dosages suitable for your body, health condition, and lifestyle.

Article Summary
Iodine is a critical mineral in the prevention of cancer that has been used in one form or another for centuries.
When iodine was taken out of food in the 1970s politicians suggested that people could get trace amounts of iodine in iodized salt.
This hasn’t worked for two reasons:
- recommendations were made to reduce sodium intake, and
- iodine in salt evaporates as soon as the package is opened, rendering it useless
Iodine consumption – which has plummeted 50 percent since the 1970s – is known for its connection to thyroid health. It is less known that other tissues also require large amounts of iodine, namely the breasts, pancreas, stomach, brain, and thymus.
Iodine has been found to:
- alter gene expression in breast cancer cells and facilitate cell death.
- be stronger than a chemotherapeutic agent widely used to treat human breast cancer.
- reduce risk of stomach and breast cancer, and has been used in the remission of lung cancer.
- support healthy immune function and regulate the stress hormone cortisol.
Given the high rate of deficiency, iodine testing can and should be requested. Here are some possible iodine testing methods:

You can get iodine from some foods (especially seaweed) and supplements. If supplementing, consult with a qualified health practitioner who can guide you on dosages suitable for your body, health condition, and lifestyle.
Hair tests show iodine level. Mine was low but I don’t want daily iodine, but just sometimes. There are Iodine support groups on Facebook, but they want very high amounts of Iodine. 12.5 mg Iodine with Se may help. People need more than iodine. Gluten may be hurting the gut lining/intestines so less nutrients absorb like iodine/Se/Zn/Mg etc. Gluten may make antibodies to the thyroid so it is hypo or hypo thyroid. Gluten may hurt all glands…pituitary/liver/adrenals/pancreas etc. Fixing the root cause is good. Asian people may eat sea weed. The ocean maybe polluted and have radiation. Hair tests for good minerals/heavy metals and detoxing by Far Infrared Sauna may help. The thyroid hormone is made of iodine. Raising oxygen burning in cells by increasing thyroid medicine may stop cancer.
Hi, this is off the subject of iodine but I couldn’t find a place for comments on the page I have a question about…. I would like to buy the detox series for my son who has autism, epilepsy, and detox issues. I’ve bought detox programs in the past but it was completely unrealistic for a 12-yr old boy with autism – fasting, 5 days of only juice, enemas, etc. I am wondering if your detox program would be doable for my son before I buy it or even appropriate for children.
Thanks so much!

My sister has stage 4 cancer she is doing chemo for rectum cancer liver and she also has lung her whites are good her liver platelets are low what can she do
Hi Georgette,
The best advice we can give you is to consult with one of the doctors/experts that we interviewed in our Global Quest Series. Here is a link to get their information: https://thetruthaboutcancer.com/experts-info-sheet/
I have heard that thyroid problems were linked to iodine deficiency. The problem with eating too much seaweed is that they come from contaminated waters. Would organic seaweed be better? I have heard that beans and tuna contain iodine. I eat a lot of beans and tuna. If I go to my GP doctor, would she be able to check whether my iodine is high or low?
Before supplementing with Iodine, we should investigate the root of the problem. It may be more than just one. Look at Selenium levels – it is crucial for activating thyroid hormone. In Hashimoto’s, supplementing with Iodine may destroy your thyroid due to aggravating attack of thyroid peroxidase antibodies on your thyroid gland.
If the iodine that’s added to regular table salt evaporates so easily, what about the iodine contained in unrefined salt? Is it chemically bound with another/other minerals?
What if you have an allergy to iodine?
My friend has an “allergy” to iodine after a surgery that used iodine, but usually allergies are not to an element. The body/brain/thyroid needs iodine to work right. Seeing your iodine level may help. Hair test…had iodine on it and my iodine was low. Maybe iodine hurts you since Se is low. Low Se may allow iodine to make H202 which may hurt the thyroid etc.
I don’t understand the statement that the iodine evaporates as soon as the salt box is opened. When I was a child — 1940s and 50s I knew ca couple of people with goiters. I haven’t seen one in my adult life at all. I thought iodized salt was responsible for this. What is true?
Iodine on the periodic chart is a liquid so maybe some of it disappears when it is hot.
Nikole’s question remains. If goiters were common before iodized salt, and they are not common now, what made the difference, if not iodized salt.
It is important to distinguish between IODIDE and IODINE and TINCTURE OF IODINE The following (except my conversion of Celsius to Farenheit) came from Wikipedia.
Iodine [is] a shiny black crystalline solid that melts at 114 °C and boils at 183 °C to form a violet gas. IN OTHER WORDS, IODINE CAN BECOME A GAS AT 183 DEGREES CELSIUS, OR 365 DEGREES FARENHEIT! Not happening in normal conditions.
Tincture of iodine or iodine tincture is … also called weak iodine solution. It is usually 2–7% elemental iodine, along with potassium iodide or sodium iodide, dissolved in a mixture of ethanol and water. Tincture solutions are characterized by the presence of alcohol.
Potassium Iodide, which is added to salt, looks very similar to regular salt.
The assertion of the author of the article that iodine evaporates once a box of salt is opened is unsubstantiated.
Cancer maybe due to gluten/GMO which may hurt the intestines. Ozone may help and herbs. No gluten/dairy/soy/sugar/GMO/food with a label…taking vitamins/good oils/minerals…probiotic…LDN..detoxing. Mushrooms/Essiac/liposomal Vit C and liposomal glutatione and more may help. Juicing/soup may help. I have Lyme and my platelets were low. Ozone may help Lyme/cancer and much more as it raises oxygen in the cells. Far Infrared Sauna may help detox chemicals/heavy metals. Too much detoxing may hurt since it may remove the good minerals. Chemo may hurt the gut lining so less nutrients absorb. Sugar/pain killers may feed cancer. Progesterone may help the immune system. Alternative people in her area may help her get supplements/diet help and ozone help. Ask at a Health food store for who maybe good in her area for natural help.
Great question! I am curious as well! Please respond!!
I am confused by a statement at the beginning of this article. “the iodine in salt evaporates as soon as the package is opened, rendering it useless.”
My ‘regular’ salt has potassium iodide in it, which is a solid, and as far as I know does not sublimate (evaporate). Furthermore, current salt containers are made of porous paper/cardboard, and anything that was in a vapor state would not have to wait for the package to be opened to escape.
Help me understand, please!
It may depend on the temperature of the factory/air etc. Some iodine may still be there and help, but is still lower than maybe needed by people to be healthy. Too much iodine when Se is low may cause autoimmune attacks on the thyroid. They used to put iodine in bread instead of bromine so I am sure they lost some iodine there also. Each person can take a hair test and check iodine levels and see if iodine in salt is enough to help. Sea salt has 22 minerals. Kelp maybe from polluted oceans. Taking 12.5mg of iodine may help many people, but each person needs to figure out what works best for them. I just take iodine sometimes after I go swimming in Cl water or think I am feeling slower. I don’t take iodine daily. Food in the grocery store may not use iodized salt. There are iodine groups on Facebook . Dr. Brownstein book on Iodine is good.
In a comment above, I noted that Iodine becomes a gas at 365 degrees Farenheit. Iodine cannot just vaporize away at under normal conditions.
It is IODIDE that is added to table salt, not IODINE. Potassium iodide looks just like ordinary table salt.
I have a bottle of Lugols iodine which destroyed the rubber eye dropper due to evaporation so maybe that is what people noticed.
Lugol’s Iodine is a 2% solution of iodine. It is a tincture of iodine. It is a tiny bit of iodine dissolved in water and alcohol.
The alcohol did not eat up the rubber….the iodine did.
Elyn Jacobs, please comment.
Now brand- Detox support/Now brand- Liver Detoxifier and Regenerator at night with lots of water may help detox. Detoxing too much may remove good minerals. Sea salt has 22 minerals. Dairy/gluten may cause seizures. Below is the short version of what I do as an adult. Ozone may help raise oxygen in cells. Green vegetables may help detox. A chiropractor is trained in nutrition and may help or acupuncturist etc. Best wishes.
No gluten/dairy/soy/sugar/GMO/food with a label etc. and vitamins/good oils/ LDN and detoxing help me. Vit D3 5000IU, zinc 50mg if detoxing, 2000mg fish oil, 2000mg evening primrose oil. 2000 mg lecithin, Phosphatidylserine/DMAE, krill oil, CLA, Coenzyme Q10, Rhodiola, Mg citrate 400mg, Vit C, 5000mcg of biotin, Nature’s Plus- Source of life multiple, HCl and Now brand- Super enzymes with meals, dairy free probiotic, Vit B12 methylcobalamin shot/spray/under the tongue kind/intrinsic factor kind, MTHF folate, coenyzme Q10, rhodiola, may help brain/body/thyroid/depression/immune system and more. Gluten is wheat/barley/rye/corn…oats has gluten with avenin…and there is a small amount of gluten in rice. GMO corn/soy/canola oil may hurt. Amour thyroid maybe needed since gluten may make antibodies to the thyroid. Coenzymated B vitamins far from synthetic kind made me calm.
Sunlight (helps the immune system and helps to heal the gut lining),exercise, organic food, good water..not tap water, cooking by scratch pure food….. no food in a box/bag/premade/label/restaurant which may help avoid hidden gluten. Certified gluten free food may have 20ppm of gluten…too much. Nuts not sold in the shell/meat basting/some spices may have hidden gluten/food with a label and lotion/make up etc. One restaurant cooks special for me…rice/veg/tea/extra mushrooms (no meat since the woks may have MSG/gluten in them).
EDTA/DMPS IV chelations from an Alternative doctor, 600mg of cilantro, organic sulfur, Now brand- Detox support, Far Infrared Sauna and more may help detox. Hair tests show good minerals and heavy metals. Heavy metals can block thyroid and other chemical reactions in the body/brain.
LDN may help block hidden gluten/heal the gut lining and help the immune system, but the Celiac diet is still needed. 100% no gluten..no hidden or microscopic gluten may help. Cutting back on gluten or cheating by eating gluten hurts the immune system. It may take 1 1/2 months to heal the gut lining after getting hidden gluten. HCl and enzymes with meals and gluten enzymes help me. There are now gluten enzymes also a person may use that may help, but LDN helps block gluten in the air/on the skin and all day long.
Amour thyroid has some T3 and Calcitonin. Synthroid is only T4..may not convert to T3. Zn/Se/enough iron/strong probiotic may help convert T4 to T3 for thyroid.
Alternative doctors/chiropractors/acupuncturists and more may help with health/vitamins etc.
Books: No grain No Pain, Wheat Belly, Grain Brain, Dangerous Grains and The Autoimmune Fix and more explain Celiac. Peter Osborne/Tom O’Bryan on Facebook/Youtube.
I want to send this information to my sister in law. You have a place to click to share the information but when clicking there is no way a sending anything. Only a test to see ones cancer risk.
Hi Ron,
The best way to share this article with someone would be to send them the link to it.
COPY an item (sentence, paragraph, full page, entire article) = then PASTE it into an E-mail for each recipient. This works every time. I have become NOTORIOUS by e-mailing all my relatives.
Is there a difference between sea iodine and I or idol?
What is the best iodine supplement to get? Which iodine supplement is effective against breast cancer?
