Iodine Helps Prevent Autism

Published on September 2, 2013


New research shows a troubling correlation between a woman’s thyroid function and her child’s risk for autism. This video talks about a study showing that when “mothers had very low levels of thyroid hormone early in pregnancy the chance of having a kid with autism was multiplied by 4 very seldom we see these strength of association.”

The study published in the August issue of the Annals of Neurology brings crucial attention to iodine supplementation, something the medical community has recently begun to frown upon up to the point of creating a phobia against oral iodine. It was an ill designed Brazilian study that is used by doctors as a reason to stay as far away from iodine supplementation as possible. I have actually talked to a Brazilian doctor who went ballistic with just me mentioning the word iodine!

Dr. Gabriel Cousens in the United States says, “Historically, as early as 1911, people normally took between 300,000-900,000 micrograms daily without incident. How is it that now only 1/5,000th of this dose is now considered safe? Even the Food and Nutritional Board at the Institute of Medicine has set the tolerable upper limit of 1,100 micrograms of iodine daily. Other researchers have used between 3,000 and 6,000 micrograms/day to prevent goiter. Iodine is found in every single one of our body’s hundred trillion cells. Without adequate iodine levels life is impossible. Iodine is the universal health nutrient and brings health on many levels.”

Dr. Gustavo Roman, with the Houston Methodist Neurological Institute and researchers in the Netherlands, studied thousands of pregnant Dutch women and found a lack of iodine in their diets affected fetal brain development. “I think for the first time we have the possibility of finding an explanation of the problem but most importantly we have a way of preventing this from happening,” says lead author Dr. Roman.

The most common cause of thyroid hormone deficiency is the lack of iodine in the diet. Researchers in this study believe that one in seven Americans is believed to be iodine deficient but Dr. David Brownstein has tested 5,000 of his patients in the Detroit area and has found over 90 percent to be deficient.

After testing over 500 patients, I found that 94.7%

of my patients are deficient in inorganic iodine.

                                                                     Dr. David Brownstein

Dr. Roman said, “I think it’s very important that women of reproductive age measure the amount of iodine in the urine it’s a very simple test and if the levels are low they need to go back to using iodized salt to prevent this from happening.” The problem with his suggestion is that there is little iodine in iodized salt and what is there evaporates rapidly when sitting on the table leaving nothing to absorb.[1]

Insufficient maternal iodine during pregnancy can result

in a permanently lowered IQ as well as thyroid problems.

                                                   Dr. David Brownstein

Pregnant and nursing women need 220 to 290 micrograms of iodine a day, according to the Institute of Medicine. Tests on 60 brands of pre-natal vitamins that listed iodine as an ingredient on their labels found many fell short of the stated amount.

In my book, Iodine—Bringing Back the Universal Medicine, we see that much higher levels of iodine supplementation have been used in studies since the early 1900s. Dr. Brownstein uses between 200 and 300 milligrams of iodine daily, with higher doses for more serious and difficult diseases. The 11th edition of the 1910-1911 Encyclopedia Britannica cites the “usual” doses of 300-900 milligrams (300,000-900,000 micrograms!) of iodine daily.

“At 6 grams daily (which is 6 million micrograms/day or 6,000 milligrams/day!), a much higher dose, iodine has been used to cure syphilis, skin lesions, and chronic lung disease,” says Dr. Cousens. “From a larger physiological perspective, it is important to realize that the thyroid is only one gland of many glands and tissues that needs iodine. Other glands/organs/systems with high iodine uptake are the breasts, ovaries, cervix, blood, lymph, bones, gastric mucosal, salivary, adrenal, prostate, colon, thymus, lungs, bladder, kidney, and skin. Iodine is found and used in every hormonal receptor in the body,” he states.

Dr. Roman encourages women who are pregnant or who are trying to get pregnant to take prenatal vitamins that contain iodine. Again this is a bad suggestion for iodine is best taken as a standalone supplement not as part of a multivitamin formula. The best forms of iodine are liquid. Nascent (atomic form of iodine) or Lugol’s iodine. Both are ideal for children and adults alike.


My favorite iodine and the one I personally use is Nascent Iodine from LL’s Magnetic Clay. Nascent iodine is iodine in atomic rather than molecular form and traces its history back to Edgar Cayce. It is an iodine atom that has an incomplete number of electrons meaning it can hold an electromagnetic charge. Nascent iodine is recognized by the body as the same iodine that is produced by the thyroid so it is absorbed effortlessly by the body. It is not inexpensive so I always also recommend Lugol’s and any other iodine even if in pill or topical form (marked for topical use only – to be used on the skin only….not for ingestion) if there is no other iodine to be found. Even topical applications can be effective.

    I have been diagnosed with Graves Disease which I am positive was caused by iodine poisoning. I had multiple CT Scans (for cancer) during which large amounts of iodine contrast was given before every CT Scan. I became sicker after each CT Scan. I later developed Graves Disease. Can anyone give me advice on the above scenario since it sounds like a different problem from iodine deficiency. I have read that it could have been a result of a selenium deficiency beforehand. It seems that you need high enough levels of both selenium and iodine. I have tried numerous supplements including thyroid throu (which worked up to a point) and selenium but to no avail. I am at a point where I am considering getting the thyroid removed surgically. The high levels of T3 and T4 are causing other severe symptoms that I can’t ignore…Any advice would be helpful…

    • Juan Rodriguez

      I think the Iodine used in CT Scans is radioactive… not the same as regular Iodine.

  • Bonnie

    I had my thyroid completely removed (papillary carcinoma) and have used both synthetic and natural thyroid replacement medication. The natural dessicated pig thyroid seemed to feel the best, though here in Canada the brand is not batch tested. I too want the health benefits of taking iodine and am unable to find out how to use it seeing as I am without a thyroid. I am not satisfied with the thyroid replacement situation as it stands now. It feels as though I have never chemically/physically recovered from the removal of that very important organ…not ever felt healthy/normal since. I believe the cancer was the result of low iodine levels in the first place. What would you suggest I do to help myself?

  • Ric Cross

    I have friends with autistic children and I am afraid to recommend iodine… I tried nescent at 12.9 ml maybe 3 or 4 drops a day. It was great at first then I realized I wasn’t sleeping so I cut back. After a week I started getting headache and heavy phlegm drain back of throat. Stopped iodine all together and got what seemed to be the worst respiratory infection I’ve ever had but it when away after a week… I think if it was that bad of an infection it would not have gone away on it own. what do you think. I also remember body temperature dropped and felt very cold in the beginning of the phlegm and cough! thanx for your response….

    • Dear Ric,

      This could have been a coincidence or it could have been a part of detoxification. Iodine can flush the body of chloride, fluorides and bromides and begins this as soon as you start taking iodine. This can certainly cause symptoms though the cough and phlegm seem unusual. Many people do a number of things to decrease the symptoms of this cleansing of the body and what usually helps is to make sure your selenium levels are adequate or to take additional selenium, to increase Vitamin C, and to increase salt or to do Dr. Shevin’s salt loading protocol. Bromide cleansing is the most likely to cause symptoms so if you have a high bromide level this could have been part of your difficulty. You can read more about bromide and the salt loading and iodine protocols on the breast cancer site where they are involved in a special project to determine the effects of iodine on breast cancer patients.

    So how much is recommended for a pregnant or nursing woman?

    • Julia , the research does not make any specific recommendations for the amount of iodine needed but instead states: ” If you are planning to become pregnant have your doctor measure urine iodine and thyroid function beforehand. If you have just become pregnant have your doctor measure urine iodine, thyroid function and begin using prenatal vitamins, making sure iodine is present.”
      The US government fact sheet on iodine states:
      Median urinary iodine concentrations of 100–199 mcg/L in children and adults, 150–249 mcg/L in pregnant women and >100 mcg/L in lactating women indicate iodine intakes are adequate [3]. Values lower than 100 mcg/L in children and non-pregnant adults indicate insufficient iodine intake, although iodine deficiency is not classified as severe until urinary iodine levels are lower than 20 mcg/L.

      Everyone needs at the very least the RDA of iodine and pregnant women need slightly more than women who are not pregnant. The recommended amount for pregnant women is 250mcg. per day. which should be available in a good prenatal vitamin. However some are found to be deficient in the amounts they claim to provide. So if you use Lugol’s or Nascent Iodine you can rest assured that by following label directions you will have adequate intake. One drop of Nascent Iodine provides 400 mcg. of iodine.
      Depending on individual circumstances Dr.Sircus would recommend more be taken during pregnancy. No need for urinary iodine testing and it will be of benefit to you and the baby to start using iodine as a supplement.

      • Juan Rodriguez

        Women in Okinawa Japan, which have the longest lifespan on the planet (along with the healthiest elderly on the planet), generally get 13.5MG of Iodine on a daily basis. The brand Iodoral contains 12.5MG per pill and from what I’ve read, the women who’ve used it swear their kids end up INCREDIBLY smarter than other kids, from using this.

        • Lord Windemere

          That is a miscalculation. The real figure is closer to 1mg.

          I don’t ever want to see that number in print again.

    It is true, I am treating autism with Iodine and I have had success,

    Dr.Luka Hajdar
    Medical researcher in Albania

    • squint9

      You cannot “treat” Autism. It is a developmental failure in physical brain tissue. Any benefits you are observing are probably due to the child’s overall health improvement when their iodine levels are restored properly. This is a good thing regardless.

      You CAN treat pregnant mom’s with iodine deficiancies to ensure they have proper serum levels thus preventing iodine-related developmental failure in their babies in the first place.

      With all due respect, doctor, you might want to take a refresher on biochemistry.

      • IMVAUser

        Dr. Sircus believes in an aggresive protocol: chelation of heavy metals, magnesium, iodine, sodium bicarbonate and clay baths for treating autism. Its very important to provide the substances that will improve glutathione levels in these children.

        • squint9

          Dr. Sircus is, at best, an uninformed practitioner. At worst, a charlatan. The loss of magnesium will have a profoundly negative effect on bone structure and growth. The loss of iodine will lead to gout in various places including the joints where the the resulting pain will be extreme. NaHCO3 is essentially an antacid and has wide uses in cooking, pest control (it’s murder on cockroaches), and many other uses). Clay baths are merely a method of extracting cash from the rich, bored and/or desperate. As for glutathione, while all cells in the human body are capable of synthesizing glutathione, only liver glutathione synthesis is essential. Vitamin D3 is the only human-ingestible compound that has been shown to increase glutathione levels (and that takes more than a week). And, while glutathione is beneficial to the overall health of a person, it has NOTHING to do with Autism whatsoever.

          • Lord Windemere

            I wouldn’t be too sure about that. Glutathione helps to chelate mercury from the body.

  • Michael

    A very informative article. Thank you. In Argentina it is sometimes difficult to find decent supplementation. Would you have any idea what I should expect to be able to find here or what would you suggest? Thus far the best I have been able to come up with is a topical application from the pharmacy. I apply it on my arm fairly heavily about the size of a silver dollar and judge if there is a deficiency on whether or not it remains after 24 hours. Any comment about this test? Thanks again.


    • Michael,

      Try this site down your way to get iodine…Lugol’s:

      The test is not proven, some believe it is affected by the weather so absorption rates will differ but many use it and find good corelation. .
      Best to you!
