Why Salt is Not Enough- Clearing the Iodine Confusion

There’s mass confusion and paranoia about iodine, and that’s what prompted me to write today’s article. It actually dawned on me last night (while talking to a person with Hashimoto’s thyroiditis) that iodine is used all over your body. She thought it was just used by your thyroid and read someone’s blog about it, and became very afraid to take it. It’s in salt, the “iodized” salt, but that is not nearly enough iodine for many of you.

Although iodized salt has been the most effective public health initiative to attempt to reduce iodine deficiency, and thus hypothyroidism (and cretinism), it’s not that practical. The advocates will say it costs less than 5 cents to “iodize” a ton of salt, but the opponents feel that the amount of iodine isn’t enough, and besides, you’ll get hypertension from all the sodium in salt if you try to use it for iodine replenishment.

So today, I want to clear up the confusion about iodine:

1) Iodine is needed and essential for your thyroid and proper thyroid hormone production.

2) Iodine is needed for proper conversion of T4 to T3 as well as utilization of thyroid WITHIN your cells.

3) Iodone is NOT just for your thyroid, it’s needed in all your cells, each and every cell has a receptor for it.

4) Iodine is especially important for your breasts and prostate. If you have a disorder with your breasts or prostate, the first thing you should do is check your levels of iodine, God forbid if it’s deficient your risk for reproductive cancers becomes much higher.

5) If you have a documented allergy to shellfish, or to contrast media used during imaging tests (MRIs, CTs), that is not an allergy to iodine. Reactions to contrast media are likely due to the high osmolar or ionic content of the actual dye. The primary allergen in shellfish that causes your allergy or anaphylaxis is called tropomyosin. I know many, many people who are deathly afraid of iodine supplementation because they’ve had a reaction to shellfish/seafood, but again, that is not usually to iodine.

6) If your primary source of iodine is from salt, by the time you get enough iodine, you’d have to eat so much salt that your sodium levels would skyrocket, not a good idea to depend on iodized salt for iodine.  Besides that, typical table salt is stripped of 80 minerals to it’s bare backbone of NaCl (sodium chloride) so it is nutritionally naked.  I carry my own unrefined salt in my pocket because table salt isn’t what I want to put into my body.

7) Iodine deficiency is associated with impaired mental development.

Consider Iodine Supplementation
Iodine supplementation can improve health on every level, however it’s not for every single person reading this today.
I don’t think you should take any healthy mineral randomly, not iodine, not magnesium, calcium, potassium, or  lithium. But if you NEED a particular mineral, then it’s okay, it change your life within a few days. Hopefully my article today will quell some fears.
How do you know if you need iodine?
Testing is possible. I will get to that momentarily.

Warning  signs of iodine deficiency (often coincide with signs of hypothyroidism):
Fatigue, weakness or apathy
Brain fog or mental disability
Dry skin or brittle nails
Hair loss
Miscarriage
Constipation
Depression or sluggishness
Congenital hypothyroidism (a.k.a. cretinism), this is when babies are born with severe mental challenges, they may be deaf, mute or have spastic disorders of their arms and legs. It occurs because mother is insufficient in iodine, and therefore thyroid hormone.

Since iodine is used all over your body, in all of your organs especially your breasts and prostate, you need to make sure you read this and forward it to every man and woman you love.  The truth is, TRILLIONS of cells have a receptor site for iodine and NEED it for their very survival.

Sadly, many of you are starving yourself of iodine because of fear. Perhaps you read about dangers of taking too much, or maybe you read that iodine is a radioactive mineral. (It is when it’s used as the drug for Graves’ disease).
But I assure you natural iodine -the type I am talking about today- is not radioactive, that is silly! It is as natural (and needed) just like other minerals including magnesium, calcium, potassium, selenium,  chromium and others.
We are not afraid of those.

Whenever there is an area of radioactivity, like Chernobyl or Fukushima, everyone rushes to buy iodine, either SSKI, or Nascent iodine or other forms of Iodone, and they do that to protect their thyroid. You see, natural iodine helps to displace radioactive iodine. It’s a little more complicated than that, but the point is NATURAL iodine is needed as a form of protection from the radioactive sort. An article a few weeks ago in August 2015, was entitled, “Fukushima Disaster Causes a Dramatic Increase in Thyroid Cancer.”  There are at least 103 new diagnoses this year alone, which is staggering for the area. It’s not from natural iodine, it’s from radioactive iodine. Ah, but that is possibly what conjures up the fear. Natural iodine is protective to the thyroid gland, it does not cause thyroid cancer!

The fear surrounding iodine leaves many innocent people with uncomfortable conditions such as thyroid disease (it’s epidemic now),  prostate problems, breast cancer and fibrocystic breast disease. When you test women with those disorders, they are almost always deficient.

Natural iodine is not the same as radioactive iodine which is used in Graves’ disease and also found near nuclear facilities.The body cannot thrive without natural iodine. Right now, I’ll share examples of how important natural iodine is to you, because I have a feeling no one has mentioned this before:

* 
Iodine has well-documented research when it comes to healthy breast tissue and women will often claim iodine alleviated fibrocystic breast pain or breast lumps.

* Iodine may help shrink uterine fibroids; in fact, one of the very first conventional treatments for severe fibroids was to paint a woman’s uterus with iodine!

* There’s a correlation between reduced iodine and lower mental IQ. A developing fetus is particularly susceptible to brain damage if the pregnant mother is severely iodine deficient, so much so that there are initiatives all over the world to fortify pregnant and lactating mothers with iodine to ensure healthy brain development. According to Dr. David Brownstein, author Iodine: Why You Need It, Why You Can’t Live Without It, the amount of iodine in prenatal supplements is woefully deficient and what he calls “a public health disaster.”  The right amount of iodine is absolutely crucial to a pregnant or lactating mother because too much (as well as too little) will lead to hypothyroidism. Iodine has a very “narrow therapeutic index.”  I have many physicians reading this so I will now post the conclusion from April 2015, Journal of Clinical Endocrinology and Metabolism, where researchers evaluated over 7,000 women:

“The upper limit of iodine intake during early pregnancy in an iodine-sufficient region should not exceed UIC 250 μg/L, because this is associated with a significantly high risk of subclinical hypothyroidism, and a UIC [urinary iodine concentration] of 500 μg/L should not be exceeded, as it is associated with a significantly high risk of isolated hypothyroxinemia.” Here’s the link for the study.

* Iodine deficiency is a risk factor for thyroid cancer. This has been shown in several different papers and trials, most recently discussed in Thyroid Research (June 2015). The right amount of iodine is crucial, too little or too much will harm your thyroid which sucks up iodine like a sponge.

* Iodine deficiency is well-documented and known to cause or at the very least contribute to hypothyroidism, goiters and autoimmune thyroid disorders like Hashimoto’s.

* Iodine supports testicular and prostate health so it’s important for men to get their levels tested and supplement if needed before BPH or prostate cancer occurs.

* Iodine status determines nodule growth. Most goiters and nodules are due to iodine deficiency; there are a subset of patients who may develop a goiter from “iodide” deficiency.

* Iodine supports our reproductive organs. There is a lot of research done on breast, endometrial, and ovarian cancer and natural iodine. In 1976, Lancet concluded, “Increasing dietary iodine intake may reduce the risk of these cancers.”

 

What in the world is happening…
Initiatives to fortify foods with iodine have been ongoing in New Zealand, Denmark, the United Kingdom and other countries where iodine is actually revered instead of feared. According to the World Heath Organization guidelines, systematic iodine prophylaxis is recommended in women planning a pregnancy, during gestation and lactation in order to prevent maternal, neonatal and infantile consequences of mild-to-moderate iodine deficiency. I can only sadly imagine all the women in this country who fear iodine who become pregnant while deficient! Testing (properly) should be mandatory for all pregnant women.  Methylation testing should be too, but that will be addressed in another blog from me.

The low-salt diet advocated by many physicians may have certain merits, but all-in-all, it is a disaster for your thyroid. Not that “iodized” salt is the answer, I don’t think so, but natural UNREFINED sea salt with some color is! Everyone who is on a low-salt diet is probably iodine deficient. Did you know that low iodine is a contributing factor for AFIB, cardiac arrhythmias and congestive heart failure?

The Problem With Salt
Aside from mass confusion and fear, we have the problem of salt. At the outset of this article, I told you why salt was not ideal.
Fortified “iodized” salt contains only iodide. That’s only half of what your body craves, in terms of iodine. The body needs BOTH iodide and iodine, there are two forms of the mineral.
Your thyroid craves the iodide form.
Your breast and prostate crave the iodine form.
That’s why high-quality forms of iodine supplements contain it in it’s COMPLEXED form.

But here’s the catch, if your body can’t convert the iodide to iodine, your breasts and prostate suffer.
That’s why supplemental forms appear to be more useful to certain people. If you try to eat more salt in order to get more of the mineral you will kill yourself because you’d have to eat pounds. Again, eating salt is not the most ideal way to get iodine into your body.

Another terrible problem is the US recommended allowance (USRDA). It’s horribly low at 150 mcg (micrograms).
In my professional opinion as a pharmacist, that is not nearly enough to support good health. All of you eat salt, go ahead and test yourself with a urine iodine test and see if you have enough. You may, but you may not. Which brings me to testing…

Testing Iodine
Urine. You can test your own levels of iodine with a urine iodine test. No blood is required. The skin patch test is extremely popular, however it is not too useful in my opinion. It’s almost like a magic trick because it will evaporate on pretty much every one.  This could lead you to think you’re low in iodine when perhaps you are not, what we call a false positive. So a 24 hour urine catch is a better way to evaluate iodine status than blood or spot urine.

Blood. If you want to look in the blood, measure your “thyroglobulin” levels, abbreviated as Tg. The thyroglobulin blood tests is a more sensitive biomarker of iodine status than thyrotropin or the thyroid hormones like T3 (triiodothyronine) and/or  T4 (thyroxine).  In a paper that reviewed 34 different articles, researchers looked at levels of urinary iodine as well as Tg levels. For the purpose of their review, a median Tg <13 μg/L and a median UIC ≥100 μg/L (UIC ≥150 μg/L for pregnant women) were used to indicate adequate iodine status.  They actually excluded all of the studies conducted in subjects with either known thyroid disorders or those with elevated Tg antibodies. All in all, they concluded that Tg was a good biomarker of iodine deficiency.

How can you become deficient?

Many things can cause you to become iodine deficient, let’s go through those now because they are shocking:

1) GOITROGENS – these are compounds found in foods that you commonly eat; consuming too many goitrogenic foods will cause your body to run low on iodine so moderation or avoidance for a few weeks is the key. The goitrogens suppress the body’s usage of iodine and thus, the formation of thyroid hormone. The most common goitrogenic foods include the crucifer vegetables like broccoli, cauliflower, kale, Brussels sprouts and cabbage. Others include turnips, soybeans, alfalfa and cassava root. Cooking them helps by deactivating the goitrogenic compounds, but the problem is that many of you eat them raw, or they are in your greens drink powder mix, thus you are (over time) suppressing thyroid function by suppressing iodine.

2) Swimming pools. Yes, if you’re a swimmer, or you enjoy your hot tub a lot, the chlorine in your water will deplete levels of iodine quickly.

3) Showering with regular tap water, instead of one that has a chlorine filter on it.  How many of us reading today have a chlorine filter on our showerhead? Probably no one. It’s the same deal as swimming pools. Chlorine can also trash iodine levels because the chlorine competes for the same receptor sites as iodine.

4) Eating white bread, laden with bromine.  Bromine found in bread and steals iodine. Good time to tell you, cooking with vegetable oils that are brominated.

5)  I saved the best for last, DRUG MUGGERS! That’s my specialty, I have been writing and speaking about drugs that mug essential nutrients since 1999. I wrote the book on it. Did you know that common drug muggers of iodine are among the most widely prescribed drugs in the world? Some of the offenders include fluoroquinolone antibiotics (Levaquin, Cipro, etc),  certain antidepressants and cholesterol medicines.

How can you get too much iodine?
1) By taking medications that are high in iodine. For example, the popular “Cordarone” or “Pacerone” known more commonly as amiodarone, is a drug used for cardiac arrhythmias. It’s extremely popular. It happens to have a very high dose of iodine. It can cause thyrotoxicosis.  The iodine content in 200mg pill of amiodarone is a whopping 75mg! That’s per dose!

2) Taking a thyroid supplement that has a lot of iodine in it. Many thyroid-supportive supplements focus on providing nutrients to help your body produce more thyroxine, so they are loaded with iodine. (FYI, my ThyroScript only contains only 500 mcg, which is half of 1 mg. That is relatively nothing, many supplements have 6 to 12.5mg of iodine, in a single pill!  So if you are wondering if you can take my Iodine Complex 6.25mg with ThyroScript, yes you can, if you are found to be deficient in iodine. Do you need to take both supplements? No, you do not, ThyroScript is a stand-alone supplement, it may be all some of you need for maintaining healthy thyroid function).

High doses of iodine, say those above 8mg taken daily, may be  okay for some of you, for a few days or weeks, but it’s not something I recommend on a long-term unless you are routinely monitored and woefully deficient. You would also want to have selenium on board, as selenium primes the body for iodine. Taking selenium is important, once that level is within range, it’s usually safe to begin iodine supplementation.  Taking iodine in the absence of selenium can be harmful.

While on the topic of thyroid, you may also be interested to learn that Mayo Clinic researchers tested over-the-counter natural thyroid supplements. This interested me because I actually make a thyroid supplement. Mine is non-glandular, by the way.  Anyway, in 2011, the research led by Dr. Bernet tested 10 different “thyroid support” supplements based upon their popularity among consumers.  They found that 9 out of 10 brands tested contained T4 (thyroxine).  At the dose recommended on the respective labels, four of the pills delivered would deliver T4 at doses that could produce about 9 to 91 mcg of T4 per day!

Keep in mind, a typical daily dose of prescription Synthroid (also a T4 molecule) ranges on average from 50 to 150 daily mcg. Some of the supplements contain T3, the active form of thyroid hormone. I don’t know about you but I don’t want to be consuming drugs in my over-the-counter supplements, especially if I am already taking a drug!!!  Many of you take medications like Levoxyl, Synthroid, Armour and Nature-Throid, so taking a supplement with them could be very dangerous. That’s why I formulated a non-glandular supplement that supports peripheral conversion of T4 to T3, rather than trying to force your body into making more T4.  If this is confusing, refer to my book, “Thyroid Healthy: Lose Weight, Look Beautiful and Live the Life You Imagine.”

Buying Iodine
If you’re deficient in iodine, and would like to buy a brand, you can ask your physician about what he or she recommends.  Many of you will also be asking me what I recommend.
So here’s what I look for.  I prefer you take iodine in a “complexed” form so it provides iodine and iodide.
The inert ingredients differ from brand to brand. Here are some excellent supplement choices that meet my approval:

1) Iodine Complex 6.25 mg (milligrams = 6250 mcg) by Script Essentials, that is my formula.
Learn more by clicking here.

2) I-Throid 6.25 mg (milligrams = 6250 mcg) by RLC Labs sold on Amazon here

3) Iodoral, 12.5 mg (milligrams = 12,500 mcg) sold on Amazon here

Dosage
Knowing how much to take can be tricky so I suggest you get your levels tested, don’t over do it iodine, just take what you need until your levels rise to normal range.
You may feel better because as the iodine binds to the tyrosine in your body, it forms thyroid hormone so your symptoms of low thyroid may disappear, that is one way to know that you have enough. I would stop at that point, not just keep taking it forever and ever.

Like any good thing, too much is incorrect for your body. If I had a specific dose that would work for millions of you reading today’s article all over the world I would offer it gladly, but unfortunately, you are each unique. Some of you may respond to 100 or 200 mcg, and others will need 12 to 24 mg!  I have no way of knowing what is right for you based upon your lab work.  This kind of thing is to be determined by your doctor, if only through testing every 3 to 4 months.

I’ve been told that Ligols Iodine is something that could be used for raising the iodine level. Your thoughts?

    A friend recommended the J.C. Crowe brand iodine. So I bought the 2% bottle. Then I got afraid to use it because I put it in my smoothie with some other supplements I take and wasn’t sure about the interactions. I only put in 3 drops but decided not to drink it all because of precautions I read about on line (not yours!). I guess I do need to get my levels checked. I do use kelp everyday for this purpose What do you think about this brand?

    Hi Suzy. Firstly you have my utmost respect. Thank you for your information that is always so valuable to us with Hashimoto’s. I have read that if you are Hypothyroid then taking iodine is good, however if you Hashimoto’s then the iodine can make your autoimmune worse. Can you please explain why some scientific papers state this? And if this is correct? Also if you have Hashimoto’s but have a normal TSH, should you still be on thyroid medication?

    • Suzy Cohen October 6, 2015 at 6:03 pm - Reply

      Depends on your free T3 levels and circulating antibodies. Medicine is there to put back what your body doesn’t produce.
      The other questions you have are good, they are answered in this article, as well as other articles here on my site. And in my book, Thyroid Healthy, a bible for thyroid sufferers, click here. Please refer to that, as it is too much to retype here.

    Fluorosilicic acid in water removes iodine from your body. Glyphosate locks up the nutrients needed to transport iodine back into the body. Glyphosate can be found in genetically modified foods. Glyphosate can now also be found in bread when RoundUp is used to terminate the growing cycle of wheat. The combination of fluoridated water and GMOs and non-GMOs with glyphosate often result in very low iodine levels in the body. Almost everyone with cancer is very low in iodine. Iodine helps our immune system destroy any Candida fungus in our blood that can trigger cancer. [These comments oversimplify a complex topic. Do your own research.]

    I really learn a lot from your information. However, I have asked people in the health world if they have heard of you and they have not. SO, who are you and where do you do your research and come up with the conclusions you come up with? I’m suffering with a lot of stuff and have paid a lot of money going to a wellness place. I can barely walk because my feet feel like they are breaking across the tops and the balls of my feet often burn. I hurt around my hips down my legs…tired…my body has gone from good to horrible in just over a years time. I used to be a petite 4-6 size and am now almost 190 pounds at 5’1. I’m 61 and feel like an 80 year old must feel. I’m not me 🙂
    I want to feel better but not sure what is up with me. My whole body hurts.

    Hi Suzy, Thank you for all the great information about iodine. What do you do if you are allergic to iodine? My mother and I both have a thyroid problem. My mother is deathly allergic to all shellfish (iodine). I have a milder allergic reaction to crab, salmon and cod. I use sea salt with iodine but should I try taking a supplement. If so, what would be the best one? What would you suggest for my mother?
    Thanks so much, Suzy.

    • Suzy Cohen October 6, 2015 at 5:23 pm - Reply

      I’d avoid.

        A high thyroglobulin has been associated with iodine deficiency- it is also used to monitor patients status post thyroid removal-low Tg- means all or almost all of the tumor is gone.

    thank you Suzie,
    I was made aware of this by a ND located in Bloomfield, Michigan. He stressed the importance of Iodine (yodo) in human health. He is quite specific. However, I love what you have done. There is confusion. Dr. Brownstein stressed the vital nature of iodine, but he is just one voice.

    Too many of us have been led to believe that the iodine added to (mined and processed) table salt is just what we need. Over here on the other side of the Pacific, there is ignorance too. I tried to get my mistress to eat more iodine. she was not interested. So we moved to the sea and now she gets iodine in the shellfish that she loves to eat. We do not over-do it. d

    Thank you so much for all info on iodine. It’s so helpful as there is so much confusion out there There is an area you did not mention and that’s the divide in opinion on whether if one has nodules it’s ok to supplement with iodine due to the potential reaction on the nodules. I have nodules in my remaining half of thyroid and am boardering in the test as being severely deficient in iodine,however my nutritionist and doctors are very cautious as there is info that taking iodine can cause the nodules to swell! I have many of the symptoms you list for many years and I feel now that maybe the iodine is the major cause in my health. I so want to find the missing link but have been left afraid to try taking it.. Thank you again.

    I developed Graves disease following a deeply emotional trauma. It was fully confirmed diagnostically by my endocrinologist. I refused surgery or radiation treatment. I followed a naturopathic protocol of good nutrition and emotional support. Within three months my thyroid testing returned to normal.

    I am not certain that I should completely avoid iodine for fear of re-activating the Grave’s disease. Most articles about iodine refer to the hypothyroid state with no mention of hyperthyroidism. How does the information about iodine supplementation apply to those of us with a tendency toward hyperthyroid?

    • Suzy Cohen October 6, 2015 at 5:58 pm - Reply

      If you’re predisposed to Graves’ it’s easy to just avoid it altogether, however, in my book, I feel like an autoimmune assault to the thyroid isn’t related to iodine per se, it’s more about Th1 and Th2 imbalance. So I would test for iodine status (properly) as I have indicated in my article and go from there. Most people forget, there are trillions of cells in your body starving for iodine. It’s not just for the thyroid gland. The breasts and uterus are starving. Fibrocystic breast is often a/w low iodine.

    2 years ago I decided to take some iodine in the form of Lugol’s solution. I had fibrocystic breast pain so I figured I could use some.

    Didn’t end well for me. I started with the doze of 0.5 mg and then bumped it up to 1.2 mg in a course of 5 days. My heart rate shot up to 130, I couldn’t sleep, I couldn’t go out, I basically couldn’t function for the next 3 months. 3 cardiologists, gastroenterologist and neurologist couldn’t figure out what was wrong with me.
    All of my thyroid hormones and TSH were also absolutely normal.

    Fast forward 2 years and I am still struggling with heart palps although not so severe anymore. Now there are a lot of things I cannot do. I can’t do yoga, I can’t eat fish more than once a week (I could eat plenty of fish before), I can’t put topical iodine on me more than once a month, I can’t eat thyme and rosemary, I can’t drink coffee, some essential oils (lemon, lime) trigger heart palps, pretty much anything that has even a slight stimulating effect on the nervous system would trigger heart palpitations.
    Supplemental GABA is my best friend now.
    Can anyone explain why this could happen? I searched the web and found one article mentioning that sensitive individuals could develop severe tachycardia from iodine but there was no explanation as to why that is. I had been able to apply iodine topically with no problems before I started taking it in orally.
    Thanks,
    Dila

      Dila, I just want to mention that my husband had been taking GABApentine for restless leg syndrome for a while, then started waking up with headaches in the morning. This went on for quite a while, then I was having trouble sleeping at night so found a supplement, (Melatonin Sleep support) thinking it would help me sleep. I used it for a few nights, and started waking up with headaches (I rarely get headaches). Upon reading the back of the sleep support it has GABA in it also, so decided it must be what’s giving my husband headaches also, so he quit taking it and the headaches quit. So I guess what I’m saying is if you start getting headaches upon awaking it might be the GABA that you’re taking, as it is a brain hormone, I believe.

    Susy, Thank you very much for this important information. I read your book, it helped me tremendously to understand thyroid function. Half of my thyroid was removed 4 years ago. I take 32 mcg. of Nature-Throid. I was wondering if I can supplement with your formula Thyro script. I have been told by a naturopath to take kelp capsules. Thanks for your advise.

    • Suzy Cohen October 6, 2015 at 5:21 pm - Reply

      I can’t say what’s right for you Edy, but we have thousands of people who do well with their NDT drugs and ThyroScript (which is intended to support peripheral conversion) not to drop in more iodine or more thyroid hormone. I let your drugs do that for you. Ask doc to be sure.
      You would not need kelp with that, it’s a stand-alone multi-tasking (and if I can say so myself pretty amazing) formula.

    Hi Suzy, I have written you before about the parallels in the veterinary world. Well here is another perfect example. While in my vet practice, I saw a large increase in hypothyroid in dogs in the past 25 years. I believe that you are exactly right. Environmental increases of chlorine, fluorine and bromine have also affected the canine world. So many of my clients drink filtered or bottled water, while giving their dogs tap water, full of chlorine and fluoride. As well as bromine in the manufacture of many plastics, such as dog food bowls, water bowls, toys etc.
    So thank you once again for teaching us that all creatures are affected by our changing environment.
    An interesting side note: Cats have shown a relative increase in HYPERthroid in the same amount of time. I am not sure why the opposite effect. The feline world is certainly very different from the canine world.

    Thank you for all you do to help educate us with your many articles on how to keep ourselves healthy. This article is an eye opener and I shared this on my Facebook.
    I have been taking synthroid for many years. I did not see you mention familial issue. My mother had thyroid issued, is this why I developed hypo thyriodism? I take .88 now started w/ 100. Just bought your Thyroscript. I am 65 now. I like the ingredients in your product better then what synthroid is made of. I’ll let my husband take these for now. He has type 2 diabetes and has learned from your book. He couldn’t put it down when we first got. We have been a fan of your for a good while now. Your are a God send. Thanks for all you do.

    Hi, i would like to know if i can test for Iodine with the TG if i have Hashimoto’s, did not understand the part that says that in the test they excluded people with elevated antibodies of TG (like i have) and with Hashimoto’s. Or should i test better with the urine test? I have the Iodoral and JC Crow Iodine but don’t dare take it for all the conflicting info i have read, some said it is ok with Hashis but others said it is very bad. I have fibrocystic breast, seven thyroid nodules but i don’t take any thyroid medications. Will appreciate if you can shed some light into this.

    What role does iodine play in ventricular tachycardia and AFIB of the heart? My husband has developed these issue since taking Levaquin this past January. His blood work up in December 2014 showed his T3 to be on the real low side but in the range markers. He is also sensitive to most heart meds. He is 77 and been good health until now; he takes no other meds except trying to tolerate 400mgs of Multaq since last week; it puts him down. How should we proceed?

    Hello Suzy,

    Thank you for the great article. I agree…confusion about iodine intake is huge! I am in the midst of functional medicine training and at the last IFM conference I attended ( and in the blog posts after) there was much disagreement about both testing (what kind to do) and optimal Intake. I tried asking my patients to take 12.5 mg of Tri-iodine (per Dr. David Brownstein’s recommendation) and in less than three months three of my patients had developed goiters which went away after stopping the iodine. Since I have tested levels using ZRT’s urine test and found that all patients tested have been “normal”. I live in Wisconsin and thought that since we live in the “goiter belt” many patients would test low but our test results do not show this. Now I am concerned about the lab reference ranges – i.e. Could they be set too low? I am curious what your thoughts are on this and lab(s) do you recommend for testing please? Also what us the reference for the article using the 34 studies please?
    Thank so much for all the wonderful educational work you are doing! Please keep your articles coming!!!

      Yes, avoid the goitrogens as best you can.
      Iodine may be taken by people without a thyroid. Every cell in the body requires it, iodine is used by the reproductive organs such as the uterus, prostate, breasts, etc. The doctor can test your iodine levels (via urine, NOT SERUM) to determine if this is right for you. Stay tuned to me, as I am coming out with a FABULOUS PRODUCT for people with thyroid conditions. And I mean FABULOUS!!! But I can’t say anything more right now 🙂

    My blood work regarding iodine levels came back “normal”. I do have hashimoto’s thyroiditis, goiter right side of thyroid, been on Synthroid for 10 years. My antibodies are elevated, having trouble converting T4-T3. I purchased your Iodine Complex. Should I be taking this even though my levels came back “normal”? I’m trying everything to get the antibodies down.

      Selenium is thought to be better for that. Goiters are often iodine deficiency (but not always). Take supplements only under the direction of your practitioner, not on what you read on a website be very careful okay. You’ve got a lot going on here.

    Suzy I have very very soar breasts and they increase in size tremendously mid cycle. My diet is very natural with no processed foods and low in salt! Years ago my iodine was low, my t3 is low normal! I have used lugols solution on arms( liquid form) a few drops. Potassium iodide and iodine! Within one hour there is no trace of color it’s completely absorbed? Would this indicate need for suppliment action? What is your opinion on topical product? Thank you, Julie!

    • Suzy Cohen October 6, 2015 at 4:50 pm - Reply

      I believe those are signs and symptoms of a condition that is termed “estrogen dominance” which is really another way to say “progesterone deficiency” so I’d see a doctor to rule that out (or rule it in). I’ve covered that many times, please use my search box.
      As for your iodine skin test, that is not a reliable test. You may or may not be deficient in iodine. The skin test does that to almost everyone. I’d do the 24-hour urine analysis through your doctor.
      And I’d use Rhein or Genova for your hormone tests.

    I know this info isn’t on the topic of the above article but I didn’t know how else to contact you. I heard a story on NPR recently about a lady named Ellie Lobel who lives in the UK. The article on her can be found at [email protected] BBC dated 3-27-15. The title is “How a bee sting saved my life”. She had Lyme really bad and after about 10 years was all but ready to just give up when she was stung many times by bees and it ended up helping her recover from the symptoms of Lyme. Was wondering if you ever heard of this? The techno portion said that the 26 amino acid peptide called melittins, responsible for the stinging sensation, makes the TRPV1 channels open and in the right doses, punches holes in a cells protective membrane causing cells to explode.
    If you never heard of this, I hope it might open new avenues for you to research in order to help your husband and others!

    Just in time! Thank you, Suzi, for your amazing articles and your insight! I own your book, and also purchased it for my PCP who also enjoyed reading it. I have hypothyroidism (they don’t think it’s Hashimotos, as antibodies keep coming back negative) and was looking for a good multi – mineral (as I’m deficient in quite a few minerals, according to hair metals test). I purchased one but then read Dr. Kharrazian’s book: “Why do I still have thyroid symptoms? when my lab tests are normal!” who talks about Iodine too, saying that it’s like “pouring oil into the fire”, especially if you have Hashi’s. So, just like you said, I was afraid taking a multi – mineral with iodine in it! Even though, my PCP did a 24 urine test and determined that my iodine levels are rather lower than normal. So, I really appreciate your article, and it gave me courage of finally taking a multi – mineral that is good for the body.
    I take WP thyroid for medication (learnt about it from your book!), should I space meds and multi – minerals in time? Such as, 6 or more hours away from the meds? THANKS AGAIN!!

I take Synthroid daily, at that time, I was told to avoid iodine supplements and also soy. Has that changed? Should I take an iodine supplement?

    • Suzy Cohen October 6, 2015 at 5:00 pm - Reply

      It’s up to your doctor. They told you to avoid iodine because you had HIGH thyroid. That’s why they burned your thyroid with the radioactive iodine. But every other cell in your body depends on iodine. So to clear this up, you must do a test to determine your systemic levels. A good functional medicine doctor will understand this. Most conventional docs won’t, they may mess you up (possibly). Please go to functionalmedicine.org or acam.org and find someone who understands.

      Hi Jo-Ann,
      First thank you for your support, you can buy iodine anywhere, so thanks for your purchase with me (I do have a proprietary blend at a low dose, though that is unique from other brands)… anyway, the iodine is based upon your levels of it, not on your thyrotropin. So you do that 24-hour urine catch, and see your levels, and go from there. Some people also base their dosage upon symptoms, either symptoms of low iodine, or high, and they know when to stop when they get high (you’ll see symptoms of hyperthyroidism usually) like insomnia, anxiety, palps, things getting faster (you get hot/sweaty easy)… all signs of excess iodine. Take it with food, like all minerals.

      If you’ve hosted cancer once before, you can certainly host it again so it is critical to make yourself an INHOSPITABLE host. Please use my search box to research key terms. I have 470 something articles archived here for public education. Hashimoto’s is an attack to the thyroid gland, so if you don’t have one you don’t have Hashimoto’s, but you can certainly have an AUTO IMMUNE disorder that is causing self-attack.

    Thank you for the informative post! I have read the gamut of advice on iodine, who should take it, who shouldn’t, etc. Dr. Mercola is with you on exercising caution of not getting TOO much, however some others are concerned about ANY for those with Hashimoto’s.

    I am currently taking kelp 300mcg, 500mg tyrosine and 200mg selenium daily, for thyroid support. I have read that 200mg of selenium is the “sweet spot” of a daily dose and that you want at least some selenium if you are taking iodine (especially for those with Hashi’s).

    I’ve also read many opinions of people preferring iodine to be consumed in it’s “food form” (as in kelp) and others who claim that iodine itself is better.

    Thanks for this information! Our chiropractor does muscle testing and tested my son and I as iodine deficient (with muscle testing which I realize is a bit controversial but has been effective for us so far). We’re on a 3mg dose of iodine which I’m realizing might not be so beneficial for the thyroid. We both have symptoms of hypothyroid, him even more so than me. Being a kid though anything we can give that’s not in capsule or tablet form is ideal. Is there a reason why you didn’t include Lugol’s solution isn’t on the recommended list?

    Thank you Suzy for this timely article! I just bought your Thyroid Healthy book yesterday, and I am looking forward to getting that soon to read!

    I too was taking a Kelp supplement but I did not react favorably to it, so have left it off for now. I am also taking your Thyro-Script. I have seen some improvements, but I still have the weird neck pains on occasion (but they are much less than they were before), which I think are associated with the cysts that I developed. However, I am looking at my last blood test, and am due for another blood test coming up soon, and I want figure out what I should be testing for. Here is what I was tested for and the results this summer:

    T4 + TSH + T4F + T3Free

    TSH 1.860 (reference interval .450 – 4.500)
    Thyroxine (T4) 7.4 (reference: 4.5 – 12.0)
    T4, Free (Direct) 1.16 (reference: 0.82-1.77)
    Trilodothyroninie, Free, Serum 3.2 (reference: 2.0 – 4.4)

    Can you tell me if this is all that my doctor should have tested for, or is there another component that he should be including to really measure the thyroid function?

    Also, in the urine catch, what exactly should they be testing for? Just want to make sure if I go to my regular internist for that, that I will be getting the right thyroid measurements tested, so then maybe I can figure out what my dosage should be. I have reacted to so many things it is hard to know what the culprits are, and why things are reacting like that in my system, but I really need to do something for my thyroid. Someone else told me that she had a bad case of Lyme, and at the end of her Lyme ordeal, she developed thyroid cancer. Not that this is going to happen to me, necessarily, but I would like to find out as much as I can about how to get my thryoid back so it does produce the hormone and distribute it to other parts of the body, as needed. I definitely get what you are saying, but just want to figure out how to measure as accurately as possible, so I know what I can or should be taking.

      To answer your direct question they should be testing for iodine. Not thyroid hormones (in the urine catch). Your free T3 looks pretty good. This is rather complex, please ask a physician AFTER you read my book which will explain it very well. They need to see your reverse T3 and ferritin levels. And TPO antibodies too. Lymies don’t typically get thyroid cancer, don’t worry yourself sick like that. Ok, stay in touch. Please keep questions general.

    I want to make sure I read this correctly. In testing for iodine, when using thyroglobulin as an indicator, the higher the number, the more deficient in iodine you might be? Obviously other things may play into it, but for the thryoglobulin piece of it, lower is an indicator of proper iodine?

      Hello Theresa 🙂
      Nobody said that. People who take Synthroid may be low, may not be. There’s not a rule about that.
      Synthroid is a drug providing levothyroxine. It does not provide any form of iodine whatsoever.

        You just mentioned Synthroid has 50 to 150 mcg in the article. Does Synthroid have Iodine or not?

        “Keep in mind, a typical daily dose of prescription Synthroid (also a T4 molecule) ranges on average from 50 to 150 daily mcg.”

          Synthroid does not have iodine. It is bioidentical T4.

    Hi Suzy, I love your articles and am looking forward to reading your books as well. I’ve had two thyroid nodules for over four years that appeared when becoming ill with Lyme. Recently I took Selenium as well as I-Throid on the recommendation of my doctor. I stopped the I-Throid because my eyebrows started thinning out. She did extensive testing and the T-3 was a bit low (2.9). She decided to give me a script for Nature-Throid but I’m hesitating because of palpitations that I have from time to time due to the TBD. What do you recommend? I’d like to take your Iodine formula and try it. I’m concerned about the nodules not getting shrinking after taking selenium and also the I-Throid. Oh yeah, I was low on iodine on my first testing but it was okay upon re-testing.
    Thanks!

      This is honestly too much for me to comment about… Lyme …nodules/goiters… labs… I’m not able to quickly evaluate you over the Internet. I’m so sorry, please understand. This is a general area.
      (I like Nature Throid as a drug, doesn’t make it right for everyone).
      Iodine is used for goiters, not selenium… at least that is what I though. Follow your doc’s orders.

    Until a few years ago iodine was used to disinfect food processing equipment then less expensive disinfectants were used. Food stuffs produced in this equipment picked up a small
    amount of iodine which increased the iodine intake of those eating these products,
    All the salt added to food is of the non-iodinized variety.
    Doctors without borders paint a silver dollar size application of iodine on all patients that
    they service in area’s away from the ocean.

      No, to my knowledge, it requires a doctor to order it. You pee in a bucket for 24 hours, then give them back the bucket and they extract a little portion of the urine, and send it off.

    Hi Suzy – I seem to recall Datis Kharrazian sounded a warning note about rushing in with Iodine (without first testing for deficiency) i.e. if you have leaky gut and/or leaky blood brain barrier, and if you have Hashimotos – then, ergo, downing a ton of iodine may be throwing fuel on the fire. As if iodine can be something that can be part of Auto-Immune causation (I forget the exact mechanism and how rare that would be)

    So I’m interested to know, on a simple level, how you would recognise such bad reactions to iodine, and what might happen. No doubt testing (if you’re rich and have a Funct Med practitioner anywhere within reach) reveals all, but I just wonder if such concerns are misplaced or not, and whether there are simple signs we should learn to recognise

    p.s. I live in a country noted for low iodine in its agriculture. Come to think of it my eyebrows are a bit thin on the ends, hair a bit thinner than it used to be and energy a bit low! Just reaching for some Himalaya salt!

      You’d have symptoms of hyperthyroidism if you were getting too much iodine.
      And hypothyroidism if you had too little- that’s a basic evaluation– but it’s misleading because that is just ONE single aspect. Iodine deficiency could also show up as prostate or breast problems. You really have to test.
      I agree with Datis, you should test. People read stuff and rush in to buy it. I hope my articles are fair and balanced.

    I have Hashimoto’s and according to an iodine loading test, am low in iodine. The problem is I can’t tolerate any iodine supplementation and have a massive reaction to it. Kelp tablets are the same. I eat sea veggies in dried sheets and shrimp to try to bring it up, but it barely brings it up. I having been taking 200 selenium for several years and my antibodies are almost undetectable. It was when I gave up dairy that I have had trouble with being low in iodine. I drink bottled water without fluoride and have a shower filter. I have your thyroid book and many others. Any suggestions? Thanks Linda

    I am a nutritional therapist that has read the research (Brownstein and Abrahams) and have taken Iodoral myself and tested a few patients with the urine challenge test. However I cannot find whether it is safe to suggest when patient is on Levothyroxine (Eltroxin here in Ireland) so I hesitate when they are under endocrinologists even though many times they have not even had antibodies tested before the prescription which they are told is for life. Help?

    • Suzy Cohen October 6, 2015 at 11:07 pm - Reply

      Iodine intake (like every mineral) should be based upon the body’s levels of it.
      If you’re patient is low, you give it.
      If they are normal you don’t.
      The trouble and confusion occurs when people and doctors try to give it based upon a symptom.
      That’s like giving lithium to a person because they sometimes have panic attacks. You just can’t do that. Make sense? That’s why it doesn’t matter if they are on Levo or not, iodine is given if the patient is low and it’s that easy (Levo or not).

    Thanks for this article, Suzy.

    Is there somewhere a person can order a 24-hour urine test for themselves? I was told to take I-throid every other day based upon a spot urine test. I’m also taking WP Thyroid.

    I was told I didn’t need to take selenium, because the practitioner doesn’t think I have Hashimoto’s. But I am wondering if that is correct – partially because of past symptoms. I’ve only had antibody tests twice (both in the past few months), and they came back very low. But I think I’ve had thyroid problems for at least 15 years.

    Would an ultrasound help to rule out Hashimoto’s, and possibly help me decide if I should supplement with selenium?

    Thank you!

    Hi Suzy, thanks for a great article! I was just thinking about this exact topic the past few days and I am so confused! I have Hashimoto’s and elevated TPO antibodies. I am taking thyroid hormone. My iodine has been low ever since I first got tested for it (through a blood test) two years ago. I have tried supplementation but it doesn’t seem make my levels rise. One of my doctors wants me to take iodine and the other says that taking iodine when you have Hashimoto’s will make the autoimmune attack worse. I have read a few books that say that taking iodine when you have Hashimoto’s is a bad idea but they never say whether this is still the case when you are very deficient in iodine and have Hashimoto’s. I don’t know whether taking iodine would be helpful or harmful for me. Please could you clear this confusion up for me? Thank you!

    Iodine is not feared by the public, and yet they may falsely believe table salt is enough – propaganda does that. In fact so many people wanted to supplement with it after Fukushima, the gooberment took it away from the public. This is the same little g, (not God but playing one) that provides us with chlorine, fluoride and forced vaccines – they are the cause of deficiency. The US RDAs are low for all vitamins, then they’d be admitting vital minerals are for self repairing not drugs and thus, the gig (medicine) would be up!… One can on longer buy tincture of Iodine without a doc’s prescription. They now have fake iodine on the shelf, which may have some or no iodine, no longer the tincture, iodine as the main ingredient. It is my understanding, putting this on ones skin, how long it stays or not, is a sign of deficiency.

    I spoke with a pharmacist about the missing iodine tincture (BTW another intelligent one :”) and because he knows of its importance, he sees that the drugstore is stocked with iodine supplementation because he takes a 12.5 mg daily, though they no longer by law can carry the tincture – he directly blamed the rush on iodine after Fukushima and thus “g”, taking it away. He showed me the bottle (from behind the counter) for 45$, by prescription only.

    I read somewhere a sign of deficiency was trailing-off eyebrows or missing eyebrows. My mom started painting hers on (they were all gone) by age 50 and she was dead from cancer by age 72, but was knowingly fighting it for 10 yrs. When I learned that I made an effort to supplement (my eyebrows are trailing off) though I should have years ago for I’ve a long list of symptoms – that included cold extremities (keeps me cool in summer) dry hair and nails, and a brain fog from time to time and lethargy. I now notice people with a hoarseness seems to be very common.

    6 months after being diagnosed with Hashimotos and taking 60mg. of Armour Thyroid I developed a complex cyst in my left breast and began bleeding from an ovarian cyst. I am 60 years old and have never had a history of cysts. The functional doctor that diagnosed me did not warn me that this could cause an iodine deficiency.

    After reading Dr. Brownstein’s book again and getting information from Life Extension Foundation’s data bank, I realized that my better functioning thyroid was requiring more iodine and most likely affecting my breast and ovaries. I also learned that I had a 200% greater chance of developing breast cancer at my age and not having had a history of cysts.

    I was treated so rudely by a breast surgeon when I refused a biopsy and dismissed as foolish by my gynecologist whom I thought was somewhat integrative. No doctor I talked to had ever heard this. It was a very frightening time. I did not want to spend $200 for the 24 hour loading urine test so I just bought seaweed and began eating it every day. The bleeding stopped soon and the breast cyst was smaller in 4 weeks. I just had another breast and pelvic unltrasound a year later and there is nothing there. I am clear.

    Hi Suzy, I have beein taking Armour, Thyroid (30mg) since a year. My Blood Test in Jul 2015 showed TSH as 6.31 miu/L 90.34-5.6) above hig limit and T4 level 6.5 pmol/L (7.5 -21.1) above high reference limit. My doctor asked me to take three times as much but I increased it to twice daily . My September Blood test showec TSH at 9.27 ! although the T4 improved slightly to 9.9 pmol/L.

    Is it safe fro me to take Thyroscript simultaneously or is there another option I can try? I have another blood test due in two months. I was also low on Ferritin but with Ferrous sulpahte supplement it has increased from 6 to 23 in two months.Pls help! I am almost turning bald, have patchy skin around my shoukders, and irregular period ( although I’m not menopausal). I am 46 years old, my fitness level is pretty good and so is my diet ( i think).

    Suzi,
    I really respect your research and information gathering for us. I’ve followed you for two years now, and learned a lot. Your article here is very interesting, so I should consider supplementing, if my urine test shows I need extra, OK. I have Hashimoto’s thyroiditis. My body doesn’t convert T4 to T3 very well. Lately, I finally am now with a clinic who will be testing things like iodine levels for me. Currently, I’m doing well taking a compounded Cytomel, only 2.5 micrograms 3 times daily. But, I must tell you about an experience with an iodine ‘supplement’:

    Three years ago, when I was taking Levothyroxine, I got to a point where I felt very hypothyroid with weakness, fatigue, and I naively went to new a so-called functional medicine doc who didn’t do any tests on me, and simply sent me home with a Standard Process brand of some kind of supplement that had the herb Bladderrack, which is rich in iodine. After 4 days, my heart was beginning to race horribly and I was trembling and couldn’t sleep. I suffered horribly like this for 24 hours. It was obviously too much iodine for me needs. I only weigh 110 pounds, so that must be a factor, as well. I just don’t need a lot. Doesn’t body weight determine a dosage needs ??

      Maybe your rT3 is high because it is converting in THAT direction. Look at page 18 of Thyroid Health, and the chapter on Transport.

I had eaten mostly Mediterranean sea salt ( harvested around 1980, before the water became so polluted), but now use Himalayan salt, as I understand it contains numerous minerals. I used Iodine for a while, but stopped when I began the Himalayan salt. I used to eat seaweed daily, but now feel concern for its growing environs….

    Hi Suzy,

    I wanted to get back to you with an update after you had given me the advice on this thread regarding my thryoid problems, a couple of weeks ago. You looked at my thyroid test results, and made some recommendations. You said you thought the T3 looked good but that I may need to test for the iodine levels as well as looking at ferritin and one of the thryoid hormones, perhaps thyroglobulin, I think or maybe it was another one.

    I am now reading your book – it is really fascinating – and I am enjoying learning more about all the different thyroid problems, as well as how you explain the issue with the T3 not being distributed properly to all the cells of the body, and differences between T3 and rT3. I just wanted to tell you that I also looked into doing your DirectLab tests for the thyroid panel, but unfortunately the state I live in does not support the testing through them Maryland. This is not the first time I have run into this problem, unfortunately! But I did also ask my internal medicine doctor about the testing for iodine through 24-hour urine, as well as now, my Lyme doctor. Both of them told me they don’t do the 24-hour urine testing for iodine (anymore). Whatever that means, it isn’t available for me to test my iodine levels, so I can only go on the thyroid testing that my Lyme doctor will be doing upcoming in early November, through my blood work. I have asked him to try to duplicate the Direct Labs complete thyroid panel, so that he can test for all of it, and try to determine what exactly are my thyroid problems. I do believe I am hypothyroid, or “thyroid sick” as you describe in your book. The one thing that I have had a huge problem with were the cysts, but I think they have gone done a lot, and I have much less pain in my neck too, since I have been taking the ThyroScript formula. However, I did have to go cautiously and not take too much of that, either – meaning not two per day, but one every other day seems to be a lot easier for me. I have seen improvements (no more hair falling out), etc. but I do still have some really persistent problems that continue, and I think even though the cysts have gone way down, there is still some of that on the right side of my throat, and I have some other things that flare up – like difficulty swallowing, etc. I mentioned all of this before – I just have to be very careful what I put into my throat and digestive tract, but overall am doing a lot better with it. One interesting thing that has happened, is that this month I got a period – after three years without one. I am not sure what has triggered this, but presumably some hormones that were not working may be trying to start up again. I am 54, and the last period I had was about three and a half years ago. So, some of the hormones releasing did actually make me feel better for a day or two, but I am still having major struggle with my hormones, but they are a lot better. I was supplementing with Pregnenolone, and B5, as well as Optimal Adrenal, this past winter. I cut back on those, but I am really wondering if it is due to an improvement in my thyroid. Maybe you have some ideas on this? I was pretty sure that I was in menopause, but perhaps it was more a combination of hormonal deficiencies due to the Lyme disease, and the general mess my whole body has been in for the past four years. Anyway, it was just an interesting development, and the only thing I could think was that thyroid supplement was doing something positive.

    Well, if I get the complete thyroid panel done, I will let you know about that. I hope my Lyme doctor will do more testing on this. I have felt like my thryoid could have been seriously damaged – was even wondering about Hashimotos, but I really don’t know for sure what is wrong, but just that it has made some improvement, but still there is room for a lot more. Keeping my fingers crossed that I am however, on the right track!

    Thank you again for taking the time to write all of these wonderful books. They are really super helpful, and also really interesting! It is really neat that you have this knowledge and are sharing it with people. Thank you again for taking the time to read these blog posts.

  87. Jackie Apel October 24, 2015 at 3:30 am - Reply

    I reread some of your article above, and understand it a lot better too now that I have read the first few chapters of your Thyroid book.

    From my own experience, I do know that chlorinated water has bothered me in the past, and I actually placed a chlorine filter on my shower for that reason a number of years ago. Most recently, I do notice my tap water being very chlorinated since I have been sick with Lyme, and that it actually causes my eyes and ears to burn when I get water in them or if I get it into my nostrils, (like if I am washing my hair in the sink). This never used to happen to me, and I did not used to be this sensitive to the water in my faucet, prior to all of my complications with Lyme disease. But I am now highly sensitive to it. I used to be much less sensitive, (but still avoided swimming too much in a pool, for that very reason). Also noteworthy as an aside – I feel much better after a day at the beach, swimming in ocean water – most likely it has some iodine in it, as well as other nutrients (that we certainly don’t get in our swimming pools). I noticed a big reduction in the inflammation in my body too, just this summer after being at the beach in the salt water.

    Regarding some of the other things you mention in your article about benefits of iodine. Yes, I believe you are right that some extra iodine could help me. I do think the ThyroScript has helped me, but if the Iodine supplement might be something more I could benefit from, or try, then maybe I should just do that, even though I cannot get the urine test done. I don’t know who here in my area would do that test if my Lyme doctor won’t, so don’t know of any other way to do it. (Also, the DirectLab tests specifically say they cannot issue their tests to people who live in Maryland, New York, and one other state, so that doesn’t help much either).

    One more observation. Back in 2012, I tried taking Cytomel, because at that time it appeared that I was having a hypothyroid problem. I tried taking Cytomel because my alternative doctor in Seattle felt it would help me, but when I took it I had a major reaction to it. I turned completely white – chalky looking after taking it, due to some major in ability to process the medication at all, so I was unable to take anything, and left it alone. It appeared that my thyroid got better over the next year or so, and I was under the impression that all of my symptoms were just Lyme disease related, and/or adrenal fatigue, etc. I did not think there was anything else I could take, as I was under the impression I would be allergic to it, including taking iodine. But now after reading your article and book, I realize that this was probably an incorrect conclusion. I have added selenium into my supplement regimen though, just this past week, and will continue taking that so maybe it will help me – then perhaps I might be able to try your iodine supplement. It seems like it might be the missing ingredient.

    I have had blood tests to determine iodine levels, but in trying to convince my adult children to do this, they posed a question to which I don’t know the answer. There is a school of thought that says a skin test is a good indication of weather you need iodine. That is, painting the skin on your forearm with medicinal iodine to see how quickly it absorbs. If it lingers for a day or so, you are good. I know this is not a substitute for a blood test, but is it even a reliable indication?

    My sister, whom I now care for, was born in the 1950’s with congenital hypothyroidism, my grandmother had a goiter. Most physicians only know thyroid supplementation, nothing about iodine. I use both.

    […] Iodine.  When perchlorates are in your body, and also iodine, it is a race to the receptor site. Either perchlorate or iodine will occupy the sites, and get hugged into the cell. Because perchlorate compounds have a relatively short half-life, having iodine on board could help. Before you take iodine or kelp, read more about iodine and salt by clicking here. […]
