LUGOL’S IODINE THE QUINTESSENTIAL SUPPLEMENT: against all diseases including cancer; & infections from fungi & protozoa to TB & HIV:

update 7 November 2015: comments & feedback please.
Orthoiodosupplementation in a Primary Care Practice Jorge D. Flechas, M.D. its undated but the latest ref is 2004..
but informative 2014 iodine update video by Dr Jorge Flechas:
some points: “why women have so many more thyroid problems eg estrogen blocks iodine; whereas ovary hot nodules may cause thyrotoxicosis from secreting T2.  Iodine alerts the brain, so dont take at night! give no more than ~12mg/d ie 2 drops 15% in pregnancy, it stimulates the baby!
“Iodine ie I2 diffuses into cells whereas iodide need to be transported in; babies lack the symporter Iodide transporter, so babies need iodine not iodide.
ie thyroid, ovary and WBCs can make thyroxine- but preferably  they mop up low iodine intake. Thyroid supplements doesnt provide enough iodine for needs elsewhere .
” Millions of women in Japan and Korea on their marine diet used to normally ingest ~13.5mg iodine a day, producing very low neonate problem rates in pregnancy and with IQ far higher than average.
“in the west, Iodine has been taken out of bread and milk, and salt intake cut – associated with increased rate of ADD in USA 500% and more cancer thyroid, breast, ovaries, endomet, cretinism, goitre .. – as iodine intake and output in USA has been halved by admin policy…
the kidneys excrete excess ingested iodine, so avoiding overdose from high iodine intake.

“ie if sufficiency, a 50mg iodine load will excrete >90% . so the spot test for low iodine excretion, and 24 hr high iodine excretion, reflect defective sodium symporter problem. This corrects with ongoing iodine supplement. 80% of vegans in USA are iodine deficient due to skipping seaweed for iodine! Asians eat seaweed in everything.. the body can hold 1.5gms iodine; 50mg in the thyroid, 20% in the skin, 30% in muscles…
– if depleted of iodine, we cant sweat or use our muscles (fibromyalgia), brains, or control the breasts or ovaries.. .. just add ATP cofactor ie incl vits B2 & B3 to iodine…
“Bread & esp cooldrink’ iodine (eg Mountain Dew) has been replaced by bromine, which causes schizoid behaviour… .. Iodine reverses the immortality of cancer cells.
” 3000mg/d ester C , and highdose iodine, and B2+B3 , reverse the iodine symporter block, & abolish the fibromyalgia in 80% of sufferers. .

This Flechas review is encouraging for repletion with Lugol’s 50 to 100mg iodine /day ie 6 to 12 drops 15%; after perhaps a precautionary skin test dose for allergy.
especially for protecting breasts, cancer, diabetics, obesity, heart disease, immune, memory and stroke problems.. .

It does seem that as with vits C and D3, iodine has a minimal RDA as far as basic prevention goes ie ~0.15mg – 1mg/d for avoiding cretinism (cf scurvy with >10mg/d vit C, or frank rickets with 400iu/d vit D3) ; and at the other end of the spectrum ie treating severe disease, grams a day of iodine and vit C, and vit D3 >50 000iu ie >1mg/day..

Then longterm maintenance with eg ~12 mg iodine a day ie 2drops/d 15% Lugols,  cf 1 to 3 gm a day vit C, vit D3 ~7000iu ~ 0.2mg/day… .

perhaps the corollary may be that , (as with vit D3 eg 2million ie ~ 50mg), a massive accidental load dose eg 2gms iodine- 20ml 15% Lugols- (which apparently bypasses the detox reaction at lower ie buildup dose, and incidentally provides 1gm potassium) may be both harmless and will reload for who knows how many years- presumably provided one takes a good magnesium and selenium ie realfood Banting diet .

To test tolerance, and try to reverse my familial irreversible atrial fibrillation, I have built up my Lugols’ dose  so far  to 15% 1 to 2 tsp a day ie 4 to 8ml, ~800mg combined (I + I2) iodine with 400mg potassium K  a day;
whereas a load dose vit D3 eg 0.6 to a million units (6-10gms of standard max strength 100 cwt powder – with a good magnesium and vit K2 diet as in realfood Banting) will replete safely and harmlessly for less than a year.
Its a pity the simple IODINE urine test is- unlike the skin patch test duration- so tediously long and costly (and both can occasionally mislead),
whereas the blood  vit D calcium-creat levels are quick to take but costly  tests.. .

But in those who can afford them , the tests are essential to validate the clinical results we get with iodine and vit D3 .

quotes from authorities are in italics: please feed back on errors and experience

Massive iodine deficiency is  as universal worldwide (compared to 50 years ago) as are
*deficiencies of:                                                                                                ..vitamin C (except those who live on fresh fruit and veg);
..vitamin D (except those who work outdoors in sunny climes);
..magnesium; and
..natural saturated fats in all except keen carnivores;
..and increasing deficiency of other vitamins in the food chain, forced on the public by government-sponsored industries and “health authorities” for 50 years now;
*and unnecessary dangerous food-chain toxins ( refined carbohydrates; calcium/bromine/ fluorine/salt, aluminium, mercury supplements, synthetics eg transfats, pesticides eg glyphos Roundup, GMO foodstuffs, antibiotics ; and steroids). .

But with seafood almost wiped out by greed and pollution, and increasing global nuclear pollution, and failure by food producers to supplement   iodine never mind vit D and magnesium in the depleted food chain,

iodine repletion with vigorous Lugols iodine (with its consort selenium) is even more of a priority than concomitant vitamin D (with its consort vit K2) and magnesium supplementation, and vitamin C, plus a broad balanced other score A to Z multisupplement ..

So the dangerous scaremongering myths need to be debunked about the “dangers” of iodine at over a mg a day – when the safe general therapeutic dose is not just ~12mg/d but up to 100mg/d for longterm prevention, and over a gm/d for major diseases; ie >10 000 x the RDA. The US recommended adult dose of iodine for nuclear exposure is about 120mg, without any mention of remotest risk of toxicity.

This 1000 x order of magnitude with iodine is like
*the almost 10 000x margin between minimalistic vitamin C 10mg/d dose (RDA now 60mg/d) to avoid scurvy, up to >3v-7gm a day to treat infections, and >30 gm/day (intravenously, or buffered orally) to treat cancer;

*and vitamin D3 (RDA now up to ~800iu/d) up to 250 x more eg from 200iu /d to prevent rickets vs 50 000iu/d to treat some serious diseases, vs 2million iu single doses and 150 000iu/d for decades that have no documentable toxic effects in adults.
Infants obviously need proportionate dosing of all, not left to depend on mother’s milk when she has received no more than the usual prenatal supp folate and iron.. . .

The heaviest essential metal iodine is perhaps the most rare essential mineral – Wiki: “Iodine is rare in the Solar System and Earth’s crust (47th/60th in abundance):”- hence iodine deficiency is universal – especially now it has become fashionable in our lifetime to stop adding iodine to foodstuffs; and instead food manufacturers pump in toxic halides like bromine and fluoride (like dangerous mercury and aluminium in vaccines, aluminium in antacids) that (unlike chlorine,  iodine and refined sugars) have no essential biological need and benefit , only risks;

and recognition that commercial pure white runny salt NaCl – overdosing chlorine- is adverse because of worsening hypertension with aging and fast foods, instead of encouraging seasalt. .
The myths have been debunked that
*(unlike our essential blood chlorine in moderation), either fluorine or bromine are essential trace element halogens, any more than commercial cane sugar or fructose are biologically essential in our diet;

*and the Wolff-Chaikoff Effect myths (that iodine is toxic at much more than a mg a day) debunked by Abraham & Brownstein’s  review of scientific evidence the past century  including  Wartofsky, et al   1970  that we overdose with iodine at only 20 x the RDA (0.15mg/d) ie over a mg/ day,

*and the myth that only potass KI /sodium NaI iodides should be supplemented. The most proven iodine is in Lugols iodide providing the balance between  KI and free I2.

*Another commercially driven myth is that blood thyroid hormone levels are adequate to diagnose biologically significant iodine sufficiency, and commercial thyroxine to treat patients– the commercial hormones dont address, may worsen the serious iodine deficiency throughout the body that contributes hugely to acute and chronic, common and rare diseases

Studies of traditional Japanese after WW2 showed that their far better cancer-, cardiovascular,- thyroid health (before they emigrated to America, or took up Western diet) was attributable especially to the kelp ie iodine intake in their then-safe seafood diet, giving them an average iodine intake of about 12 mg/day- at least 100 times the current American imposed RDA of 0.15mg/d. But who can trust kelp, seafood from the poisoned oceans and rivers any more?

I recently took for a day each approx 20drops Lugols 2% pd in water ie iodine ~9mg a day; then 15% 4 drops ie 30mg/d …then up to , then 10drops ~70mg/d to test for detox reaction. I carry on with ~50mg/d,  as  many patients take it . I suppose my lack of detox reaction is not surprising since I have been detoxing for years on about 6 gm a day of a 50 -supp -multiblend( half vit C).- but no more than a mg/d of potass iodide. I  find physical and mental stamina better, no longer have  angina from stress or walking fast- which I could not do a fortnight before due to angina and fatigue. . .

One shudders to think of the billions of people – especially kids- who are dull, not achieving their full potential for lack of iodine, either because health professionals dont think we need more, or because patients are dismissed as euthyroid based on the usual thyroid lab hormone tests (which ignore iodine deficiency/excess in the majority who dont fall clearly in the over-or underactive blood hormone range).

Conventional western medicine apparently no longer considers or measures iodine deficiency, forgetting that iodine is the primary essential deficient mineral (along with magnesium, selenium, sulphur, phosphate; and iron in kids and reproductive women) for all systems in the body, not just for thyroid hormone levels- which dont reflect iodine security anywhere outside thyroid hormone production by the thyroid. .

Iodine is needed in microgram mcg amounts for the thyroid, milligram mg amounts for breast and other tissues, and therapeutically as anticancer in gram amounts.[2]- Dr. David Miller
The theoretical iodine lethal LD50 for humans ie 1/10th of rodent dose is about 2 gm / kg, eg 6gm for a newborn baby, 140gm for an adult… a bottle of 20ml 2% Lugols in water contains 400mg, a 100ml bottle of 15% in water contains 15gm iodine(ie a 20ml bottle 3g) ie a harmless dose except corrosive if swallowed neat,.

Hence retailers if at all dispense Lugols 2%; we dont lightly prescribe/dispense 15% Lugols except for topical massage. And for cancer and we stick to 20ml dropper bottles.
not even Dischem and Clicks at Cavendish stock Lugols- only 2% iodine tinct IN ALCOHOL ie strictly for burning scratches… so no retailer should sell 100ml of any Lugols prep, only 20ml 2% Lugols, as is enforced in USA. It is indeed apparently regulated in the same way here., ‘tho’ the SA Medicines formulary doesnt mention that (recommends it only preop for eg thyroid storm), nor the multidisease benefits of Lugols including on the brain, wounds, infections, cardiac, vascular, cancer lungs etc;

nor the usual DETOXIFICATION REACTIONS as heavy metals are mobilized, for which (like eg metformin) the Lugol’s dose must be started low and titrated to tolerance with lots of fluids including magnesium, seasalt, selenium , vits B. eg Brief symptoms from heavy metal detox include “headaches, agitation, palpitations, nervousness, the jitters or irritated thyroid symptoms; pimples; skin rashes; fatigue, muscle aches, fever, diarrhea, worsen sinus/asthma, and brain fog. “. , , and If these heavy metal detox reactions occur, stop the Lugols a few days, increase the detox remedies, then resume Lugols at a lower dose that you dont react to.
Threads   indicate that detox problems go away once iodine dose exceeds 50mg/d- especially if taken with a multisupp incl vit C, magnes , BCo, & selenium; and plenty of seasalt in water. (the only one of these not in a multisupplement AntiAging blend is salt).

In perspectivethe thyroid holds 50 milligrams of iodine, the breasts hold 200 milligrams, the skin holds 400 milligrams of iodine, and the whole body holds 2,000 milligrams, and possibly much more. Iodine is found and used in every hormonal receptor in the body. in 1911, 900 milligrams 0.9gm/day!) were considered usual and safe dosage. At 6 grams 6,000 milligrams/day!), iodine has been used to cure syphilis, skin lesions, and chronic lung disease. Iodine makes us smarter, helps with mental functioning. Low iodine is associated with low IQ’s with a difference of up to 13.5 points in children; but iodine deficiency is also associated with mental functioning in adults, because iodine not only chelates lead, but, according to Dr. Jorge Flechas, iodine prevents lead from lodging in the body in the first place. Low thyroid function decreases brain circulation, which slows intellectual function. low thyroid function is associated with cognitive impairment, memory loss, depression, slowness of mind, anxiety, suicidal tendencies, and a variety of psychiatric disorders. Bleichrod’s meta-analysis of 17 studies showed iodine sufficiency increases IQ by 13.5 points in children. Iodine prevents heart disease. Iodine is needed with the use of cordless phones, cell phones and now smart meters to prevent hypothyroidism. Iodine decreases insulin needs in diabetics.

IODINE ALLERGY? The risk of iodine allergy is quite low – Drs. Abraham and Brownstein were only able to identify 3 of 4,000 people who had a negative response to the iodine. People do not become allergic to iodine per se, but people react to the displacement of bound heavy metals; and can become allergic to protein-bound iodine as is found in shellfish or to the binding agents, excipients, fillers, preservatives and/or synthetics (rather than the bioavailable form of iodine itself) commonly found in tablets, capsules, and even liquids. Actually, iodine can help eliminate food allergies according to Dr. Derry.
But dont take Lugols at the same time as vit C, which neutralizes the antimicrobial effects of Lugols. so take them at opposite ends of the day.

and because iodine attacks only pathogens and abnormal cells, not our good probiotic biome or healthy cells, it has none of the risks of pesticides , antibiotics, antivirals, radiotherapy, chemotherapy etc.

despite Dr Jean Lugol having published his landmark 1829 work on his iodine complex  ie ~185 years ago, there is predictably little research on it published on Pubmed, for the obvious reason that Big Pharma and the Disease Industry and governments wont fund research on such a cheap cure, which would greatly increase survival, but in the short term reduce illness and thus need for health industry workers, hospital beds, pharmacies and new drugs.
There are apparently only three clinically relevant LUGOL’s papers listed on Pubmed ie in the past 50 years:-

from India 2012 Consul ea – confirming that painting the cervix with Lugols (the Schiller test ) and vinegar is as effective as Pap smear for screening; thus combined, the two simple cancer diagnostic paints make up for Lugols iodine for cervix cancer being only about 85% sensitive and specific ie not as reliable alone as a costly lab Pap smear…
Greece 2007 Theodoropoulou ea  confirming that preoperative Lugol’s iodine 80mg/d for 15 days in euthyroid people was accompanied by increased intrathyroid total iodine but no changes in intrathyroid hormone HI or demonstrable increases of serum T4 and T3 were observed. It is hypothesized that the maintenance of normal intrathyroidal HI is the result of the combined inhibitory effect of iodine on thyroid hormone synthesis and on the release of T4 and T3 from the thyroid.
Italy 1986 Marani ea  –Iodine is therapeutic in various pathologies where immunity plays a dominant role, eg it facilitates cure in tuberculosis, lepromatous, syphilitic and mycotic incl sporotrichosis lesions . This effect does not depend on iodine’s action on the micro-organism responsible, but on host immune boosting. . Iodine may also be used in Panniculitis, in erythema nodosum, in nodular vasculitis, erythema multiforme etc. . To establish relationship between dietary iodine and immune response, 607 infants in an area of endemic goitre were studied: 215 were given Lugol solution (2 drops- presumably 20mg? a week for about 8 months ; and 392 not. Immune response was assessed by the skin test tetanus toxoid (in the U.S. 80% of paediatric cases aged 2-10 years old were positive). A significant difference was noted in the average diameter of the infiltrations after the tetanus toxoid skin test in the two groups considered (P less than 0.001). The results indicate that an adequate iodine intake is necessary for normal retarded immune response – a fact that the disease industry and Big Pharma blatantly ignore. . . (Iodine does not have the adverse effect of antibiotics on our gut biome, or causing antibiotic-resistant pathogens)

But there are dozens of scientific Lugol’s studies not referenced by Pubmed:

The End of Antibiotics and the Rise of Iodine as an Effective Alternative 2008 Mark Sircus

Iodine and viral infection?
David Derry, MD, PhD Thyroid Science 2009 Iodine: the Forgotten Weapon Against Influenza Viruses

Mamo & Naissides International Journal of Infectious Diseases (2005) from Australia show Iodine Could be effective in the treatment of human immunodeficiency virus and AIDS-associated opportunistic infections. as it is in rodents and cats .

Inactivation of human immunodeficiency virus by iodine-releasing products Harbison & Hammer Boston, Massachusetts 1989  showed that “povidine-iodine completely inactivated HIV at concentrations of greater than or equal to 0.5% ie is highly effective at killing HIV.
Betadine is simply “a stable complex of povidone and elemental iodine, contains 9.0% to 12.0% available iodine ie 90-120mg/ml .. Free iodine slowly liberated from the povidone-iodine PVPI solution kills microbe (but not healthy mammalian) cells through iodination of lipids and oxidation of cytoplasmic and membrane compounds, thus exhibits a broad range of microbicidal activity against bacteria fungi protozoa and viruses. Slow release of iodine from the PVPI complex in solution minimizes iodine toxicity towards mammal cells.” This compares exactly with a similar iodine complex  15% Lugols which contains about 10% ie 100mg iodine /ml water .. at far lower cost than but identical safety and efficacy to the patented Betadine – a modern designer marketable patented crib of Lugol’s .. …

Iodine: Its Role In Health and Disease: New Exciting Concepts Michael B. Schachter, M.D. 2007:   Guy Abraham MD, former professor of obsts gyne & endocrinology at UCLA School of Medicine, has written papers about iodine that drastically changed my thinking about its role in health and the prevention and treatment of disease. I had been impressed by Dr. Abraham’s previous work, which showed that vitamin B6 and magnesium could be very helpful to women with premenstrual syndrome (PMS) and was eager to learn what he had to say about iodine. Through a series of articles termed “The Iodine Project,” Dr. Abraham proposed that the optimal daily dose of iodine for a WELL person is approximately 12.5 mg, which is 100 times the RDA of 0.125 mg, ie that the current prevailing medical opinion that more than 2 mg a day of iodine is toxic is wrong. He traces the source of this major blunder to a scientific experiment on rats that was published in 1948 by Drs. Wolff and Chaikoff, which erroneously concluded that iodine inhibits the thyroid gland at doses of about 20 times the recommended daily allowance (RDA) for iodine. This conclusion was later generalized to humans and can be found in medical textbooks, including endocrinology and nutrition textbooks. Guy Abraham wrote in 2005: In hypertension, iodine sufficiency resulted in normalization of blood pressure without medications; as reported by other physicians using this program. Best results were achieved when orthoiodosupplementation was combined with a complete nutritional program emphasizing magnesium instead of calcium. Obesity increases the requirement for iodine and up to 100 mg elemental iodine/day may be required to achieve and maintain sufficiency. Increased demand for iodine occurs with excessive amounts of goitrogens from the diet and lifestyle. eg, smoking increases serum thiocyanate levels, interfering with the sodium/iodide supporter function. Low thyroid iodine is associated with thyroid hyperplasia and cancer. Could thyroid hormones cause the same iodine depletion in breast tissue? The prevalence of breast cancer is higher in women on thyroid hormones. Medical iodophobia resulted in removal of iodate from bread 20 years ago, replacing it with the goitrogen bromate- which associated with increased obesity, diabetes, and hypertension, thyroid and breast cancer. Recent reports show association between low iodine intake in women during pregnancy and attention deficit and hyperactivity disorder (ADHD) in their offspring. The most plausible explanation is a decreased sensitivity of the nuclear thyroid hormone receptor to thyroid hormones. We previously reported evidence for improved receptor response to thyroid hormones following iodosupplementation. Therefore, iodine is not only necessary for the synthesis of thyroid hormones but also for their effect on target cells. This effect is probably due to iodination of the thyroid hormone receptor. The essential element iodine, which is the inorganic, non-radioactive forms, deserves more attention from researchers and clinicians. It maybe the missing link in patients currently resistant to conventional hormonal therapy.

Until 2007, in the United States, Lugol’s solution was unregulated and available over the counter as a general reagent, an antiseptic, a preservative,[11] or as a medicament for human or veterinary application .

However, effective August 1, 2007, the DEA now regulates Lugol’s solution (and, in fact, all iodine solutions containing greater than 2.2% iodine) as a List I precursor because it may potentially be used in the illicit production of methamphetamine.[12] However, transactions of up to one fluid ounce (30 ml) of Lugol’s solution are exempt from this regulation. When buying Lugol’s Solution on places like Amazon, most sellers fail to indicate the DEA tracking requirement. On the other hand Lugol’s Iodine solution is available over the counter in Canada and Mexico.
Toxicity Because it contains free iodine, Lugol’s solution at 2% or 5% concentration without dilution is irritating and destructive to mucosa, such as the lining of the esophagus and stomach.
Doses of 10 mL of 5% solution have been reported to cause gastric lesions when used in endoscopy.[13] The LD50 for Iodine is 14,000 mg/kg [Rat] and 22,000 mg/kg [Mouse].[14]
Most guidelines accept that anything with an LD50 >2 g/kg (-5 g/kg in some countries) can be classed as having a low acute toxicity[citation needed] which classifies Iodine as having low toxicity. Potassium Iodide is not considered hazardous.[15

Iodine Dosages
Treatment of Influenza and other Diseases iodine-dosages 2009 “After testing over 500 patients, I found that 94.7% of my patients are deficient in inorganic iodine. Dr. David Brownstein In this chapter I will present different views and practices from present as well as from the long past when iodine was vastly more popular as a medicine than it is today. For whatever irrational reason, doctors and patients fear iodine thus en mass do not use to its fullest potential.
Humans tolerate large doses of iodine but the ultra high doses that were used many decades ago are not required to get the most out of iodine therapy. Just a little goes a long way, as the governmental iodized salt programs showed but this dosage level was only effective for Goiter and its avoidance. It actually takes very little iodine to prevent this disease but no one ever said that was the only purpose and need for iodine in the body. Today people are more deficient then ever before because our need for iodine has increased in direct proportion to our toxic burdens especially of other competing halogens. Read on at
see lugols_dosage_chart.  . But for obvious reasons stick to 2% till you know you tolerate and need much stronger drops.
