The Thyroid, Hormone and Autoimmune Connections to FQ Toxicity

Hormones Matter Logo

This article puts SO MANY pieces of the FQ toxicity puzzle together, I had to share and keep it on this site.  I didn’t write it, but the author did an AMAZING job at explaining the connections between fluoroquinolone antibiotics and thyroid problems, so I’m sharing it on Floxie Hope.  Please share the article with your doctors.  It has a lot of amazing, helpful information in it.


It’s published on Hormones Matter.  Those hormonal systems do, indeed, matter.  They’re so delicate and non-linear though, that they’re rarely studied.  Not looking at them doesn’t make them inconsequential though.

    What I have read is that the FQs are toxic to the thyroid and that they “reduce absorption of thyroid medications…and compete with iodine.” (medical detective site)

    The connection of Fluoride/Fluorine to Thyroid issues is fairly well-documented, and there is a lot of information about it out there. Here is just one site:

    People often overlook the fact that this drug contains Fluorine

    People also often do not know the Connection of Iodine, Thyroid and Fluoride/Fluorine, but there is information out there on that too. It is briefly mentioned in this article, and many other places too.

    Quotes: “The key to a healthy thyroid is iodine, which is generally absorbed through the blood and stored and regulated by the body in the thyroid gland…

    But because fluoride is more electronegative than iodine, it displaces it in the body, disrupting thyroid function and subsequently impacting hormone levels that keep metabolism in check. ”

    There is also information out there that highly suggests Iodine can displace Fluoride as well, as more than one source mentions taking it increases output of Fluoride in the Urine, though not everyone is on board with this idea (surprise)

    Iodine in my opinion was essential to my own detox plan and recovery from Fluoroquinolone Toxicity

        what’s confusing is that a lot of bottled spring water has around .7 ppm fluoride…so why does he say that is too high?

        I spoke to a famous “bio-hacker” yesterday who totally agreed with you, Jason.

        • Linda October 17, 2015 at 6:05 pm

          wait, I think I may have figured it out…the naturally occurring fluoride is different. Then I found this: “Our tap water, on the other hand, is littered with hydrofluorosilicic Acid, a toxic industrial waste by-product that governments have been adding to our drinking water for over sixty years. Again, we’re not talking about the natural element of fluoride here, we are talking about industrial toxic waste.” from collective evolution site

          Quote “The main causes of suppressed thyroid functions are Candida, mercury and fluoride. Until the 1970’s Fluoride was prescribed by doctors as thyroid-suppressing medication for patients with an over-active thyroid!”

          Written by Walter Last, he has spent almost 40 years researching health issues (ahhh, outdoes me by a little bit…lol) and combines the training and work experience of Research Chemist, Biochemist and Toxicologist with that of Practicing Nutritionist and Natural Therapist.

        • Jason November 19, 2015 at 12:54 pm

          Also very important article written by Walter Last with many references

          Quote “Borax, similar to the equally endangered Lugol’s iodine solution, can also be used to remove accumulated fluoride and heavy metals from the body (14). Fluoride not only causes bones to deteriorate, but also the pineal gland to calcify and the thyroid to become underactive. Borax reacts with fluoride ions to form boron fluorides which are then excreted in the urine.”

      Lisa posted this on the main page and I think it would be good to include here:

      “I believe that once a person has been floxed, they may always be at greater risk for thyroid problems. As such, I do recommend a thorough thyroid panel, in particular the autoimmune component, be tested for in the acute phase and monitored for several years post flox. This is true for people already on thyroid hormone medication as well (continual monitoring of the autoimmune antibodies despite being on thyroid hormone medication). Current clinically available anti-thyroid antibody testing includes: TPO, TgAb, TSI, TrAb, and TBII. The TSI, TrAb, and TBII are every bit as important as the TPO and TgAb, and possibly more so during the acute phase. It is not enough to only test TSH, T4, or maybe TPO. I also recommend a traditional spot urine iodine test during the acute phase of FQT, as well as continual monitoring. I highly suspect that people with low iodine status are susceptible to FQ reactions. For those so inclined, testing for minerals during the acute phase would be a good idea; I would include Selenium, Zinc, and Copper in this testing.”


      Note total T3 and free T3 should be tested too

      • Jason December 29, 2015 at 6:47 pm Reply

        I should note that I really wonder if Thyroid dysfunction from the Quins even show up on Blood work at all, it might not always, and it is EXTREMELY common amongst Floxies, likely due to the stripping of Iodine away from it, so testing your Iodine level is likely at least equally if not possibly more important, and unfortunately I’m not sure how accurate those tests are for this either, its not important how much is the blood, but available to the Thyroid and at the cellular level.

        Anyone moderately to severely Floxed is very likely going to be low on Iodine, and will NEED to render this just as all other deficiencies. I would buy some Lugol’s Iodine (cheap, readily available), and then paint a patch on the belly 2 inches by 2 inches first thing in the morning after a shower (once dry). Watch this closely during the day, if it disappears before 4 hours someone is severely deficient, within 5 – 8 hours very deficient, 9 – 12 hours deficient, 13 – 19 hours a little deficient, if it doesn’t disappear until after 20 hours you likely have close to enough Iodine in the body. This is a “crude” test, but one many use and widely thought to be very useful, other tests to check Iodine levels would also be a good idea though.

        No one should be scared of Iodine, like anything important and health related that actually WORKS there is controversial information on the Internet about it, I’m sure it shows up on the Idiotic Quackwatch, and there are many other confused people out there who think it is not safe, pay not attention to them please. Listen to experts like Dr. Sircus, Walter Last, Larry Wilson, and many many more.

        Some info and user experiences here:

        • Jason December 29, 2015 at 6:48 pm

          Here is some more info, and many many links to piles more info:

          One quote:

          “Are there nutrients I should take before going on iodine? Do I need selenium?

          Experts on the use of iodine state there are key nutrients one should take to counter the detox of bromides, chlorine, fluoride that iodine will promote, as well as block negative reactions to iodine. Many start these one month before introducing iodine. Lynne Farrow of the Iodine Workshop group called these “Companion Nutrients”, and they are:

          Selenium – 200 – 400 mcg per day
          Magnesium – 400 – 1200 mg per day
          Vitamin C – 3,000 – 10,000 mg per day
          Vitamins B2/B3 (ATP CoFactors) – 100 mg riboflavin and 500 mg no flush niacin, inositol hexanicotinate form, 1-2x per day
          Unrefined Salt (Celtic) – 1/2 tsp. or more per day


          IMO probably ALL Floxies should be taking some amount of Iodine and Selenium, and lots of Vitamin C and of course lots and lots of MAG, they all helped me greatly and have many others as well.

    Just to clarify the point Linda brought up. All sources of Fluoride, natural or not, are sources of FLUORINE. The same toxic crap that is in the Cipro drug. All sources of Fluoride are toxic and bad, due to the Fluorine.

    • Linda November 19, 2015 at 7:07 pm Reply

      ok Jason, I did NOT know that. I thought the naturally occurring fluoride in spring water was ok. I have been buying different brands and they all have some. Been looking into R/O but my place is so small, not sure if the unit will fit under my sink (and then you have to add minerals back in.) I did however find that eating a couple brazil nuts can help. This is from the natural society website: Selenium is one nutrient that oftentimes is the first answer given to those seeking to combat the existence of sodium fluoride in their bodies. As FoodConsumer reports, selenium has actually been found to help block the effects of fluoride as well as fluoride elimination. A great natural source of selenium is Brazil nuts, but is important to keep your intake in balance. I don’t recommend you start eating handfuls of Brazil nuts. (They suggest just a couple)

      • Jason November 21, 2015 at 11:25 pm Reply

        Hi Linda, good to see you here again 🙂

        I love Selenium, there is a TON of info about just how good it is out there, I have read that before too, though I wonder just how much it can really do (I do take it) as Fluoride is such a lethal toxin (see the video I put on main pages… 😦 )

        I can tell you that I can not drink Spring Water anymore, I could pre-Flox, but I suspect what happened to me was years and years of Fluoridation had me close to toxicity levels already, then Cipro put me over the edge. Now because my exposure continues in Shower and despite my best efforts to negate it, every time I get too much Fluoride I get minor twitching in my legs (spring water, coffee, restaurant food, shower) which I somewhat attribute to a loss of Magnesium, since spraying Oil on legs (these days) can stop them in their tracks (early days it could dampen them sometimes, never stop them). I live in a Condo and don’t want to buy a system either, I buy RO water from a nearby store where I inspected their system to make sure it was up to “proper” standards.

        The whole Fluorine, Fluoride, “Natural Fluorides” thing can be quite confusing actually. This except below is from a post I did back in April that I think helps make things a little clearer. Note Fluorine is basically never found anywhere, because of its extreme reactivity due to it missing just one electron from being in its ideal state, and its affinity to then react with almost anything out there to gain that electron. Once it has it, it is then known as a Fluoride Ion, see below for more:


        “Fluorides are organic and inorganic compounds containing the fluorine element. Fluoride is the negative ion of the element fluorine, often is written as F-. Any compound, whether it is organic or inorganic, that contains the fluoride ion is also known as a fluoride. Fluoride is the simplest anion of fluorine. Fluoride is the most bioavailable form of fluorine. Oxidation of fluoride gives fluorine. Fluoride is little more toxic than lead and a little less toxic than arsenic. Fluorine is highly toxic to living organisms. Elemental fluorine and the fluoride ion are both highly toxic”.

        Click to access Fluoride%20Lead%20Arsenic%20Comparison.pdf

        A quote from a source on my post on page 25 (source is linked there):

        “People who are fluoride/fluoroquinolone poisoned become, almost by definition, hypersensitive to extremely small amounts, even trace exposures, of fluoride. In most cases, as long as these exposures continue, symptoms will continue. Further, people who are chemically sensitive as a result of exposure to other types of poisons will commonly become hypersensitive also to trace amounts of fluoride, a very effective poison. People who have a prior body burden (accumulation) of fluoride seem to be more susceptible to poisoning by fluoroquinolones and other fluorinated drugs, which include most general anesthesias, many chemotherapy drugs, most antidepressants, and many other common prescription medications (see our Index of Fluorinated Pharmaceuticals). At some point of saturation, most likely dependent on many variables specific to each individual, a threshold is reached after which symptoms will start and often progress in type and severity. Some effects can be permanent, ESPECIALLY if the victim does not carry out appropriate treatment. Since fluoroquinolone poisoning is a form of fluoride poisoning, it is essential to follow a detoxification program that is specific for fluoride poisoning. Treatment for Fluorine toxicity and Fluoride toxicity is the same, put NO further fluoride/fluorine containing substances into or onto the body. The body will slowly detox itself, as long as no further F accumulation continues.”


        “Bathing or showering in fluoridated water will cause you to absorb an unhealthy amount of it through your skin.”

        “Fluorine compounds or fluorides are listed by the US Agency for Toxic Substances and Disease Registry (ATSDR) as among the top 20 of 275 substances posing the most significant threat to human health”

        “The lethal dose of an artificial fluoride is 50 times smaller than that of a naturally-occurring fluoride. (showing that they are both indeed toxic) – Dr. Hardy Limeback, biochemist and Professor of Dentistry, University of Toronto, former consultant to the Canadian Dental Association”

        “As a toxicologist involved in fluoride research for over ten years, I was stunned by the Calgary Regional Health Authority’s glib comments proclaiming water fluoridation safe. The ‘fifty years’ of studies about fluoride safety, do not exist. The “ongoing intensive research on fluorides and fluoridation’, does not exist, certainly none investigating safety. – Dr. P. Mullenix, Ph.D.”

        “If you have cereal with milk and a Coke, you have overdosed on fluoride. You have exceeded the American Dental Association’s recommended daily dose by 230%”

        All tea leaves contain fluoride; however, mature leaves contain as much as 10 to 20 times the fluoride levels of young leaves from the same plant. Fluoride is the most bioavailable form of fluorine, and as such, tea is potentially a vehicle for fluoride dosing


        A couple notes on water here. First off, even if it is not Fluorinated, there are numerous other toxic chemicals in your water that you really should not be ingesting. Here is the list from my own sad water supply in the City of Toronto: (Google these to see just how nasty they are, I have not drank tap water for 20 years as I found out about this back then) Aluminum Sulphate, Chlorine Gas, Citric Acid, Liquid Oxygen (yay something good), Sodium Bisulfite, Sodium Hydroxide, Sodium Hypoclorite, Sulphic Acid, Anionic polymer, Cationic Ploymer, and of course Hydrofluoric acid. Further down the line people have it even worse as they Chloraminate the water by adding Ammonia (extra nasty)

        Now in regards to the Fluoridated water specifically which of course makes it extra toxic: Fluorosilicic acid (H2SiF6) is commonly used for water fluoridation. This form of fluoride is a toxic liquid by-product, acquired by scrubbing the chimney stacks of phosphate fertilizer manufacture. Hydrofluoric acid is a contact poison with greater hazards than many strong acids. It reacts with calcium and magnesium in the blood.


        Calcium Fluoride (CaF2) is compound of calcium and fluorine which occurs naturally as the mineral fluorite – also called fluorspar. Most of the world’s fluorine comes from calcium fluoride. Fluorides in general are toxic to humans, however CaF2 is considered the least toxic, and even relatively harmless due to its extreme insolubility. Moreover, calcium is a well-known antidote for fluoride poisoning. When an antidote exists in combination with a poison, it makes the poison far less toxic to the body. Calcium fluoride is the form of fluoride commonly found in natural, untreated waters.

        Calcium gluconate is often applied next in the case of toxicity, providing calcium ions to bind with fluoride; skin burns can be treated with 2.5% calcium gluconate gel or special rinsing solutions.[260][261][262] Hydrofluoric acid absorption requires further medical treatment; calcium gluconate may be injected or administered intravenously. Using calcium chloride – a common laboratory reagent – in lieu of calcium gluconate is contraindicated, and may lead to severe complications. Excision or amputation of affected parts may be required

        • Linda November 22, 2015 at 12:15 am

          OH, damn. I thought spring water was fine. Back to the drawing board. (It did say calcium fluoride was the least toxic, but I guess I better change course now.) You said “I inspected their system to make sure it was up to “proper” standards.” How can you tell? Also, do you add in minerals then? I read somewhere (Dr Mercola?) that the problem with R/O is that you need the other minerals that are also removed.

          I have been drinking Tulsi tea, thinking it was beneficial, not realizing it too is made from leaves. That is the ONLY other thing I drink besides bottled water. Ugh. I am so sick of removing more and more things I can eat/drink.

          Thanks Jason. (and I am only an infrequent visitor these days.)

          This is so confounding. Was just searching and found this: “ I read on Dr. L Wilson’s website that reverse osmosis water does not hydrate as well as spring water. I can certainly attest to this. Since then, I have only drunk spring water and feel fully hydrated after 8 glasses a day. Reverse osmosis, sadly, is not good for drinking. In fact, it is terrible. It does not matter if someone has added minerals back to it. These things cannot undo the damage to the water that occurs due to passing it through the plastic membrane. Examples include Dasani.

      • Jason November 22, 2015 at 12:27 pm Reply

        HI Linda. Well I’m glad to see you when you do post, you always have something helpful to say and your story is very powerful, and is a testament to IV’s, something I did not do myself.

        Yes, drinking water is yet ANOTHER confusing subject! VERY!

        I really love Larry Wilson’s website, I have copied and pasted almost the WHOLE site into my Library, there is the equivalent of probably 10 – 20+ books worth of material it took me a long time, and a lot of it is very good. However, I’ve said it before, I don’t always agree with him, once in awhile he seems to give an “opinion” not substantiated by anything significant. I found his site probably 10 years ago or more, and his opinion about water (he is one of the main criticizers of RO Water and has some good reasons). I actually started my Water research close to 20 years ago, when I found out Chlorine is also tied to Cancer. Looking back at some of his points on water now, I “almost” find some of his opinions silly (he goes a little far in making some of his points), but don’t get me wrong much of what he says is dead on too, like usual, even if he made some important omissions.

        Water seems to be one of those subjects split down the middle again, 50% of the opinions are for RO, and 50% cite the negatives and are for Spring (though it is probably much more like 70% for RO these days).

        RO Water – Here is an excerpt from my post near bottom of main page – Note too, RO Water is very acidic by nature (I verified this myself), and void of Minerals (void of everything which is best IMO) and some believe it to be a “Hungry Water” like Distilled Water too and can possibly also strip Minerals from the body (Very hard to get the the truth of that particular statement, I was undecided on it last I researched it). Anyway my solution for this is to “re-mineralize” the water by adding a Mag concentrate to it, Himalayan Sea Salt, a little Potassium, pinch of Borax and voila, clean mineralized Water.

        I also add in Iodine occasionally, sometimes Alum-free Baking Soda. Note I have tested my water post re-mineralization (easy to do with cheap PH strips) and the PH is slightly alkaline where I want it (too much could also be bad, like many things too much of anything…) (being void of Minerals is what makes it acidic, maybe you should consider a Multi-Mineral complex for your own acidic issue). I also drink water with lemon and chlorophyll in it at other times. He is correct, in saying that you can possibly imbalance the Minerals and Electrolytes in your body by doing this, this would be by only adding in certain things and omitting others for example, what he omits is that drinking Spring Water can do the same thing for the same reasons. This begs the question, does Spring Water have a close to balanced proportion of what Humans need? Probably not in most cases, then factor in each person’s current levels and what they actually need, this is yet another reason that stresses the importance of doing a Hair Metal/Mineral Analysis test, something LW is a HUGE advocate of.

        For inspection, it needs to have all the required filters (you’ll have to google this), be set up in the proper order and the proper fashion, be changed regularly, needs certain types of filters like activated charcoal IIRC and others (“bone char” filters supposed to be excellent to remove Fluoride but they are not regularly part of a RO system), the system should have a UV light, and be adding Ozone in the water at the end. Those are the big things, I don’t think I forgot anything big there but could have. Note that I’ve seen it said RO does not remove “F”, and it is notoriously hard to remove from what I have read, unfortunately I don’t have a way to test this myself, but I have seen enough hopefully reliable sources saying it does close to 90-95% of it in optimal conditions (hard to even find evidence of this)

        Spring Water probably was the best water 50, or maybe 100 years ago, its in its most natural state, as are the Minerals. The trouble is, Spring Water does NOT exist in a bubble, it is exposed to Acid Rain, Chem Trails, Heavy Metals, possibly Fraking, and who knows what else, then it too also goes through “processing”, though I don’t think any of them are actually filtering or removing anything? (Could be wrong here). Its possible there “might” be some good “fairly” pure sources out there, good luck trying to figure out which those are, with verified proof of purity and toxin free water, if any (let me know if you do think you find one I’d be curious). Here’s a bit of a head start, but there are other considerations other than “F” of course as noted:

        So Pros and Cons here to both, same with Deionizers which I eventually ruled out myself due to the negatives. Then there is even the whole “structure” of water, and restructuring of water aspect, and more considerations too. My take on this, for poisoned people, who are not only hyper-sensitive to “F”, but to ALL toxins in my estimation, I think there is only one clear choice (and I made this same choice 20 years ago for all the other reasons I mentioned, and before I was as toxic as I am now).

        BTW – I am with you on the “removing things”, and I am SICK of making and preparing everything myself, and not just foods, many things that I can’t find either natural/unadulterated, effective, etc, one day I WILL start my own Health company largely out of necessity (and other great non-selfish reasons of course 🙂 ).

        p.s – Tea, I hear you here too 😦 A couple years post-Flox I discovered Jasmine Tea, this sh*t is absolutely heavenly IMO, and has many of the same benefits (and negatives) as Green Tea. Due to the negatives, I would only partake in it very occasionally, now, its even less so (all of this is the same for me for decaf Cappuccinos too, one Portuguese bakery gives me a reaction every time so can’t go there anymore but I can drink occasionally from other places with minimal “noticeable” effects, had one yesterday! 🙂 Its not a good idea, but then I always have been my own worst enemy…anyway its my little “treat” to myself).

        The truth is nothing is pure anymore these days, all we can do is our best to avoid as many toxins as possible, and detox occasionally as well to remove some from the bodies stores. Some Teas are worst than others, Green Tea in particular is one of the worst I believe, probably due to its Asian origins but the leaves might be more absorbent too I can’t recall ATM (if you can find a verified “top of the Mountain” sourced Tea, you will pay through the nose but have better purity than those grown on lower ground). Point of origin is critical, then there is the absorbent properties of each of the different types of leaves themselves. Note I am no expert on Teas.

        • Linda November 22, 2015 at 12:43 pm

          Yeah, I checked that link above for the fluoride action site (and every other one…you know how it will have a date for the last time you visited the site? Mine all say “you have visited this site many times.”) I think the R/O is not something I could physically do where I am living. I can check the “water store” here that does it. I hate having to tinker around with adding stuff back in. Also, I was thinking…I noticed several sites that have R/O filters and they say they remove 97.7% of fluoride…so, I’m thinking, if I buy a water that supposedly has .06 mc, it’s probably not much different. (cognitive dissonance.)

    I took a NSAID after being floxed and the symptoms of neuropathy came back with a vengeance!It took 2 weeks to subside!My question is will I ever be able to take them again.?they are the most effective for pain and I am wondering whether in a year or so I will be able to use them again.Or do they take you back to square one?
    Secondly I have always taken Augmentin and had only good results but I have read on this site that Augmentin could produce the same symptoms as being floxed.Does this also apply for ever or will this be ok after a while?

  6. Balky February 3, 2016 at 5:44 am Reply

    Also is it possible that a floxie has damaged mitochondria and that the flowed person also has mitochondrial disease!

    Please reply as to my earlier question about NSAIDs
