@Corngold said in Iodine as a game changer:

Is there something I'm missing?

*) Iodine in salt
Table salt is NaCl (sodium chlorine), 60 % of which is chloride. As chlorine is a halogen, it’s not a part of the solution: You add a layer to the problem.

*) iodine in milk is coming mostly through a disinfectant applied to the cow's udder after milking. It is probably betadine (povidone iodine). The solution contains 10% povidone, yielding 0.5-1 % available iodine (I2)
Although Betadine contains iodine, it does not provide iodine supplementation necessary for thyroid function (IK). The povidone-iodine solution is a mixture containing povidone, hydrogen iodide and elemental iodine.

*) Remind: We need I2 and IK
See the video below for a more comprehensive model: Iodine vs Iodide vs Molecular (+ the instability of this ion)
https://www.youtube.com/watch?v=D87dxtsjHPI Iodine (Video 6’)
When we say Molecular Iodine we are referring to I2. => About the molecular structure of an atom and electron prevalence (valence layer = last peripheral layer of electrons).
NB: This short video is fine to perceive how I- links to I2 to form I3- and why halogens are not very stable.

*) Which kind iodine is used and where?
The thyroid and skin use almost only KI type iodides, or potassium iodide, the form of supplementation found for example in iodized table salt. But the breast, prostate, ovary and brain need molecular iodine type I2. The kidney, spleen, liver, blood, salivary glands, intestines and muscles necessarily all have a joint contribution in both forms (56). The fight against cancer, probably also (57). And all these organs are abandoned to their sad deiodized fate...
Woman breast needs more than what is allowed through food, even when eating fish twice a week and drinking half a liter milk. And by the way – for men aged > 65, prostate requires I2 too. Breast and prostate need I2. But the average iodine intake will not be high enough to reach another organ than the thyroid…

*1 I eat free range chicken eggs twice a week. Most laying hens are today fed with food supplements enriched with iodine, hence the final concentration found in the eggs. Which is not the case, obviously, for eggs from organic chickens who manage their diet alone on soil poor in iodine, and for whom no dietary supplement will possibly be offered... Their eggs will then be as deficient in iodine as their diet.
*2 The amount of iodine in milk can vary by a factor of 1 to 10 depending on the quantity of food supplements offered to the cows by their breeders... Add to this an unexpected source of iodine: antiseptics (iodized) used to prevent mammary infections in cows, to maintain and clean the udders when milking the animals. Result: these types of “Betadine” also leak into the milk but it not a problem since it’s to lower the dose of antibiotics.
Indeed in large farmers the livestock is fed partly on flour, grass and hay, depending on the seasons and production needs.
Margaret Rayman (94) measured the iodine content of 47 plant-based drinks available in the United Kingdom (soy, almond, most milk substitutes were naturally low in iodine, their concentration representing 2% of that of cow's milk. Only 3 of the 47 drinks were fortified with iodine (95).
According to the results of the latest Inca Study (individual study of food consumption) (96), “Products based on meat, fish, eggs (MFE) contribute to 22% of iodine intake in adults (including 9.2% for fish), followed by dairy products (excluding hot drinks) at 20%. Other important carriers of iodine are fruits and vegetables and fruit and vegetable products (12%, including 6.9% for soups and broths), cereal products (12%, including 6.4% for breads and dry bread products), hot drinks (7.7%) and condiments, herbs, spices and sauces (6.8%). In this study, algae are considered vegetables, in accordance with European nomenclature”. (97)

*) The assimilation of iodine is supposed to be very low and progressive.
It is very likely that the ideal tissue stock is close to 1500 mg (1 500 000 mcg or 1.5 g of iodine) and that the daily absorption does not exceed a few tenths of one mg per day. It therefore takes months to replenish a low stock. Probably six months according to Dr. David Brownstein. (1)

*) Ray PEAT on iodine
RP has not written directly on iodine. We didn’t talk about iodine elsewhere than in the thyroid in the years before 2000.
Peat has been interviewed – by Rita Lee, I think, for the blog “To Your Health” – July 2008. But again, he was then pulling the worms out of his nose.
https://www.functionalps.com/blog/2011/10/12/the-myth-of-iodine-deficiency-an-interview-with-dr-ray-peat/

• For Rita Lee, a lack of iodine is a myth: She titled her post: “The Myth of Iodine Deficiency”
  For R. Lee, what is higher than RDA is excess iodine and consuming excess iodine in supplemental form (more than 150 micrograms daily) can inhibit thyroid function. Same problem with goitrogens like cruciferous vegetables or estrogen-like inducers (unsaturated oils, soy products, lack of glycine in cysteine-rich meat, etc.).
  Decoder lucH: All what is in excess is counterproductive. She makes an over-simplification + amalgam. Not pertinent when we only refer to RDA for Iodine as being the right target.
• For Ray Peat (paraphrasing what Ray was saying, albeit not in those exact words of course). Note RP didn’t extensively write on iodine but only on thyroid extracts and implications when thyroid didn’t do the right job.
• A dosage of 150 mcg iodine is safe.
• It’s easy to recognize a chronic iodine deficiency, since the thyroid gland will enlarge.
• "People taking iodine feel good/euphoric but it's cause iodine attacks the gland and causes a rush of thyroid hormones»
• “People who don't live in the Andes usually get enough iodine"
• "Iodine improves mitochondrial health along with vitamin E and co-Q10"

*) One statement from bigdoobydoo on reddit.com:
I believe Peat's negative attitude on iodine supplementation would have come from him, experimenting with it and noticing acne / viral symptoms etc. all of which would have probably been from bromine or fluoride being displaced rather than the iodine itself.

*) Momentary conclusion from LucH
I haven’t read anything pertinent from RP on appropriate dosage of iodine, elsewhere than in thyroid to avoid goiter. So, I don’t expect RP to be a specialist on this subject.

Iodine as a game changer
This article is based on the work of George Robert DeLong, Francis C. Kelly, Broda O. Barnes, Raoul Vergini, and more recently David Brownstein, Gabriel Cousens, Lynne Farrow and Vincent Reliquet.
“What does iodine do for your body” will give you a completely different perspective about normal needs and why RDA advised is foreseen to avoid goiter and cretinism, not to optimize your health. “Keep them medicalized, not cured”, is one mantra we often encounter, particularly in the circle of people supposed to be initiated (Big Pharma). Not to play the paranoid, here. Just to make you aware of and give you the information, so you can understand why Big pharma is not your best friend when trying to get objective info. And as our physicians are not allowed to say sth against the NHA / HAS, you’d better get informed through non-traditional canals.

The complete post on this link. I’ll give a partial report here beneath.
https://mirzoune-ciboulette.forumactif.org/t2093-iodine-as-a-game-changer#30100

First of all, I admit that all excesses and inappropriate supplements are harmful. The question is how and who issued the recommendations, in what context.
Please, don’t tell me it’s dangerous to take excess iodine. All the excesses are “dangerous”. Do not be influenced by recommendations that are not supported by studies, or by recommendations from organizations that simply relay warnings made by stakeholders. Keep your mind open and think by yourself. So, now let’s be confronted to another approach because it could be a game changer for some of you.

What does iodine do for your body? Stop blaming poor environment for your slowing metabolism! (“How to get out of the hole”, in short)
In the last two books I read (1-2) it was set into the light that one person among 5 were deficient in iodine in the world; 1 among 3 persons if we consider an optimal range above 200 mcg. When we ingest less than 200 mcg iodine – the RDA is set to 150 mcg, the reason being not to cause a hypo or hyper-reaction of the thyroid – 150 mcg is set only to avoid goiter – this amount 150 mcg is captured by the thyroid gland (it looks like the chief carburetor). The other tissues are deprived, most of the time. Yet we need iodine elsewhere, in other parts of the body. Iodine plays an important role in all endocrine functions of the body such as thermoregulation (the best known to the general public), the neuromuscular system, the cardio-circulatory system, respiratory, renal and digestive functions and many other functions...
It is very likely that the ideal tissue stock is close to 1500 mg (1 500 000 mcg or 1.5 g of iodine) and that the daily absorption does not exceed a few tenths of one mg per day. It therefore takes months to replenish a low stock. Probably six months according to Dr. David Brownstein. (3)
The thyroid and skin almost only use iodides of the KI type, or potassium iodide, the form of supplementation found for example in iodized table salt, whose at least 50% is already evaporated. But the breast, prostate, ovary and brain need molecular iodine type I2. The kidney, spleen, liver, blood, salivary glands, intestines and muscles all require a joint supply in both forms (4). The fight against cancer, probably also (5). And all these organs are abandoned to their sad un-iodized fate...

The Toxicity of Iodine according to Merck (6)
We are induced to believe that iodine could cause chronic intoxication from daily intakes greater than 1.1 mg/day, or 1,100 mcg/day. This figure would actually correspond to the “tolerable upper intake level”, which the Pharma Lab set therefore at 1,100 mcg for adults.
You can perfectly well wonder from which right a pharmaceutical laboratory could have to interfere in such a micro-nutritional debate... But you should know that, by impregnable tradition since the end of the First World War, Big Pharma interferes in everything. Details below, in sources and references. (6)

We would need 7 mg a day
As I was searching for a study on PubMed, I saw an article written by Gabriel Cousens whom I have appreciated for a long time, even if there are nuances to be made in terms of spirituality (link between the chakras and the body meridians): “The Universal & Holistic Super Mineral by Gabriel Cousens”. He’d take 7 mg iodine a day.
I’m not telling you to do so, abruptly, without staples, and without being informed on counter-indications.
According to G. Cousens, historically, as early as 1911, people normally took between 300,000 – 900,000 micrograms daily without incident. This is over 2,000 times more than Dr. Mercola’s recommendation! How is it that now only 1/5,000th of this dose is now considered safe?!
In 1948 there was a poorly performed and, since then, never replicated study alleging what is known as the Wolff-Chaikoff effect. The Wolff- Chaikoff effect suggested that theoretically hypothyroidism could occur as a result of excess iodine. This study indicated a decreased dosage to 2 milligrams daily would be safer. (7) (This is still an amount 5 times higher than what Dr. Mercola is recommending.)

Some important iodine functions
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. In perspective, the thyroid holds 50 milligrams of iodine, the breasts hold 200 milligrams, the skin holds 400 milligrams of iodine, and the whole body holds at least 1500 milligrams, usually 2000 milligrams (2 000 mcg), and possibly much more. Iodine is found and used in every hormonal receptor in the body.
There are so many important functions of iodine that it is hard to put them into proper order of importance. The implications of iodine sufficiency go far beyond the levels necessary to avoid cretinism, brain damage, and goiter; and based on the previous cited studies, it is possible that the FDA’s recommended dosage may not even give the minimal protection.

1. Iodine helps synthesize thyroid hormones and prevents both hypo- and hyperthyroidism
   There is little awareness that when you feel sluggish, have cold hands & feet, in a wrong mood – and much more – this is to attribute to the lack / the erratic production of thyroid hormones, particularly T3 and T4. Thyroid hormones control metabolism, temperature, heart rate, glucose consumption, and even blood lipids (1-3). Iodine also helps to regulate cortisol. It improves immune function. (4-6)
2. Iodine sufficiency reverses hypo- and hyperthyroidism
   Obesity or emaciation (hypothyroidism and hyperthyroidism, respectively) both may be caused by thyroid issues, which iodine may treat, prevent and even reverse. The early 1900s study conducted by Dr. Marine proved reversal of goiter, a condition associated with both hypo- and hyperthyroidism.
   Parenthesis: I guess here that some readers will lament for the nonsense / the inanity or protest against the possible danger. It would be like throwing fuel on the fire (exacerbated immune reaction heightened in case of goiter or in the presence of Hashimoto). Wait a little and Keep reading till the end. I’m not giving my advice, on this post. I show case reports from medical practitioners.
   Fibromyalgia is another problem stemming from iodine deficiency, as is chronic fatigue.
   From a systemic holistic perspective, adequate iodine is crucial for our health. It is the universal health mineral. Its role goes far beyond the use to prevent cretinism and goiter.
   When we take into account the polluted environment (perchlorate, fluorate and chlorinate), US bakeries replacing iodine by bromine (which is one of the top twelve most harmful toxins and carcinogens on the planet) – these toxic halogen pollutants have increased over time – and the fact iodine deficiency has become more seriously pronounced in today’s population, we have to consider that iodine is very often used up first to detoxify the system. So there is not enough iodine initially, especially with low doses, to support the thyroid hormone function, unless adequate iodine is added into the system.
   There is the possibility of excess iodine, which may be a transient (26-40 hours) hypothyroidism as described by Dr. Brownstein in his book Iodine: Why You Need It. Why You Can't Live Without It. (7) Whenever we try to speed up the use / burning of iodine – so not leaving the TSH and the brain adjust the carburetor – there may happen a counter-reaction, due to a lack of progressiveness and the fact our NIS symporters (a kind of pump Na/I) are somewhat asleep / feel as if they were in a rut. NIS is a carrier system into all the cells, and when this system becomes deficient or lazy, due to lack of stimulation, the whole body can’t absorb the sudden amount. Deficiency of iodine may also contribute to low stomach acid and decreased ability to absorb B12 and calcium.
   If one is only diagnosing hypothyroidism based on TSH scores (as most allopaths do), one may become confused. We’d better take into account our feeling (…).

If you encounter some bad reaction, though you were very progressive, keep in mind two things:

• We are exceptionally allergic – not to say never – not to iodine but possibly to the protein-bound iodine found in seafood or in the medicine (provolone iodine), or to the fillers of the tablets, capsules and even alcohol found in the liquid form. Actually, iodine can help eliminate food allergies, according to Dr. Derry (p. 15 from Breast Cancer and Iodine, by David M. Derry, MD, PhD).
• Your body tries to get rid of excess halogens and killed LPS (healing crisis). Your liver is then overloaded. Need for assistance is required (…)

3. Iodine supports apoptosis (…)
4. Iodine enhances ATP production (…)
5. Iodine prevents fibrocystic breast disease (…)
6. Iodine decreases insulin needs in diabetics (…)
7. Iodine helps support protein synthesis (…)
8. Iodine deficiency is a global health threat (…)

   W: 11.1 => 11.9
9. Iodine destroys pathogens, molds, fungi, parasites, and malaria (…)
10. Iodine supports immune function (…)
11. Iodine eliminates toxic halogens (including radioactive I-131)
    Due to its chelating powers it is strongly advised / suggested one start taking iodine at a slower rate because of this detox effect. It is important to start with a low dose and build up, while checking / monitoring the urine for discharged toxins. These healing detox symptoms should not be confused with iodine toxicity.
    A pause is advisable to reload energy. Cofactors are needed to assist Herxheimer’s crisis (healing crisis) when discharging much toxin. The liver is then overloaded. (…)

18. Iodine supports pregnancy (…)
19. High doses of iodine may be used to reverse certain diseases (…)
20. High doses of iodine may be used for wounds, bedsores, inflammatory and traumatic pain, and restoration of hair growth when applied topically (…)
21. Iodine helps in the diminishing of tissue scarring, cheloid formations, and Dupuytren’s and Peyronie’s contractures, which are hyper-scarring conditions (…)
22. Iodine supports spiritual development – Gabriel Cousens speaking (…)

What then is a reasonable and safe dose in a holistic context?
It is safe to suggest that at least the guidelines given by Drs. Abraham and Brownstein for the use of 12-50 milligrams of iodine daily, for overall iodine sufficiency and wellbeing. (…)
My prudent suggestion is that as we follow these ideas, it is important to move forward carefully, progressively (with staples). The NIS symporters – a kind of pump to exchange Na/I – are somewhat asleep / feel as if they were in a rut… So progressivity, moderation (with staples) and capacity to listen to one’s sensation / to decode if we feel overburdened by liver (saturation of the emunctories; often called “healing crisis”).

Let's take the 1st source:

GRay asked my advice on this video from Mercola
https://www.youtube.com/watch?v=R085kZw3YBQ
Mercola/Strong Sista and Alan Christianson on excess Iodine
Here is my answer on the forum bioenergetics.com forum
https://bioenergetic.forum/topic/3795/mercola-strong-sista-and-alan-christianson-on-excess-iodine/3?_=1740594928529
In context
Iodophobia was almost born with the publication of a study by Wolff-Chaikow in 1948. In short, “the thyroid protects itself against an acute excess of iodine by suppressing the metabolism of iodine. » This is a transitory effect. The simple fact of providing iodine in supra-nutritional quantities to a subject regularly increases his TSH, sometimes to double digits for a period of several months, to spontaneously return to commonly accepted norms afterwards, and this, in a perfectly spontaneous manner. Dr. Vincent Reliquet.
Analysis on the link on bioenergetics.com

So:
Protect your liver and try to get rid of the toxins.

1. desmodium & cie + Se (no selenium 2-3 days before chemo)
2. iodine 150 mcg. but not just before chemo (48H)
3. Chemo
4. Take care of the liver and get rid of toxins.
5. take shake with supplement and iodine again 2-3 days after chemo if possible.
6. See how you react when taking 12.5 mg iodine. iodorate 12.5 mg.
7. If OK, 50 mg iodorate (or lugol 1%).
8. Begin T3 T4 supplementation, very progressively, with 2 weeks interval when changing. If you overload, you stop immediately for 4 weeks, before going back 2 staples back. not just the last one, but 2 or 3 staples back.
   Note: you probably need Betaine HCl (once a day at midday if you eat a solid meal). This is to help bile secretion, to optimize / make it easier for fat digestion.
   I think, you'll need much more help:

• Mint and ginger when bloating.
• an extra dose of enzymes. mainly fat enzymes (lipase) but not only.
  I know enzymedica lipogold well.
  Note; Mind the kind of vitamin C. Need the Scottish label.

@elle_em said in Immune system support post chemotherapy?:

Should I or the selenium and iodine are ok?)

I won't do that at first side.
You can't handle without the useful nutrient: First Se, then I.
You need a medical practitioner to answer your question (endocrinologist), but as the time to get a rendezvous is huge, you'll have to ask your family doctor.
To set the posology he's going to ask for TSH (blood test). Not enough. fT3 and T4 are required. Not only T3, but fT3 (free T3).
When supplementing with T3 and T4, a delay 10-15 days is required to adjust the posology, to feel alright.
To analyze the situation correctly, no interference has to be seen between iodine and hormone supplement.
I'll wait for T3 T4. Not now, not during the adaptation period (liver overburdened).
Priority has to be given to the liver and how to get rid of toxins.
you'll need cofactors to help, like vit C, magnesium bisgycinate, Vit D. to optimize energy and metabolism.
As you'll feel saturated and will try to avoid meat and fat, a shake with protein will be required if you don't want to see your bones (caricature).
=> Soup (with meat mixed) and shake with supplement.

@elle_em said in Immune system support post chemotherapy?:

Will buy Kelp 150 mcg caps Now foods and Lugol (if confirmed)

We need selenium before taking iodine.
Obliged if you're hypo.
100 mcg 2x /day at the very beginning and 2-3 days after chemo. 100 mcg the other days.
Most of the time, 95 % don't react badly when taking iodine, except whenever they don't listen to the advise for progressivity. You have to sensibilize / open the NIS symporters / pumps.
The brain needs to register you're changing the mode. TSH needs 10-15 days to adapt the level. Don't trust the blood levels but your feeling.
I repeat:
150 mcg, then 300 mcg.
12.5 mg 2 weeks
if you feel OK, 50 mg.
Stop 4 weeks if problems. And begin again. mind progressivity.
Note: you could undergo a healing crisis if you've eaten bread with bromine.
Halogens (Cl Fl Br) are going to be unloaded when present.

@elle_em said in Immune system support post chemotherapy?:

And maybe this one to start before chemo? -

Yes ok. Fine. No need to stop with desmodium, sillymarin and artischoke. I won't take it just before (the day you get chemo). Take if after (in a shake, low amount to avoid repulse).
Best to take it in cure: so 3 - 4 days before and 1 week after.

@elle_em
To optimize bile I'd take betaine HCL+ pepsin, possibly with fennel (protection) and ginger (bloating). Now foods.
I take Kelp 150 mcg caps Now foods.
Lugol or iodorate for KI and I3. Both forms are required.
Lugol 1 % solution to reach 10 mg dose = 20 drops in water (Ask for confirmation).
Note 1: I won't take iodine 48H hours before chemo since iodine has an anti-inflammatory action too.
Note 2: the druggist is going to warn you. Too high level of iodine. Big pharma has struck again

@elle_em said in Immune system support post chemotherapy?:

Do you know if it is ok to take TUDCA during chemo?

Not advised because it has anti-apoptosis effects. It would counter-acts the effects of chemo.
I'd have charcoal and / or superfine green clay when coming back home, to amalgam the circulating rubbish liquid. But when in the blood, we need something more to capture the toxins. Broccoli soup e.g. (thiol groups).

I' d take iodine before the treatment to minimize the size of the angioma.
Begin very low: 150 mcg caps 3/4 days minimum. Iodorate afterwards 12.5 and 50 mg (50 000 mcg). The thyroid needs time to adapt (12.5 and 50 mg). NIS symporters (kind of Na/I pump) need to get awoken progressively or you'll get an over-reaction / protection.
I know there is a warning from big pharma and people who don't know much about the needs and the supposed dangers (...).
I'd read the book of Lynne Farrow or have a look at my forum. Best to read the book first to lower anxiety (witnesses).

@pittybitty said in Hypothyroid->Digestion Issues->Allergies->Adrenaline->Insomnia:

Plan to use garlic as antibiotic.

OK over the principle if you think there is overgrowth.
When you eat starch there are two kinds of fiber: Soluble and insoluble fibers. We can't digest the second one. If you don't go to feces 2x a day, there is stagnation in the second part of the colon: food / residue for bacteria.
Mind the way you're going to attack the beast: need a plan or you'll make a selection.
Rather more difficult then afterwards.
I see you're not quite convinced (problem in the first part of the intestine, you think. Maybe / Possible). But you intent to take garlic to kill bacteria, which is going to be effective particularly in the second part of the colon (stagnation near the rear output).
The speed of the transit depends on the macro-elements: Slower with a mix LPG when there is fat (L). Quicker if there is only carbs.
I'll deal with delayed softgels with essential oil. See Now Foods. 2 kinds (origano / mint) (with adjuvants like fennel or ginger).
Get informed on the healing crisis too, how to manage.
