Iodine Painting

Generally iodine skin test are not reliable, yes. But iodine doesn't evaporate easily either. Try spilling povidone iodine on a bed mattress. It is still there after almost a month (I still have it). I spilled it by accident. Even on my towel it is still there (yellowish color) after several weeks. On the skin it is very unlikely that it will stay that long, even with hydrogen peroxide to detect presence of iodine as iodine salts react with it to cause the color to come back still will no longer be there for several weeks. Therefore the issue does not appear to be evaporation and air pressure, although it is a factor, but a minor one. It appears to be taking a bath or human sweat likely to wash out at least some part of the iodine, especially its salt. However in areas not subjected to sweat, such as knees, they still disappear faster than the iodine staining on a piece of cotton, cloth, wood and other things that we like it to stay clean. When everything is discussed, you just have to get an iodine tested in urine by a iodine tests to check the presence is a more accurate way. It involves taking an iodine tablets and they use a starch tests to in the urine to see if the body is absorbing or not. Those are better tests and you just have to buy their kits.

I am encouraging people to get their doctor to test their thyroid these days, as I have found so many people in dangerous levels. Turns out that doctors do not just test it automatically, you have to ask. And, they aren't up to date with reading the results, anything over 2. for the TSH is going bad. 1.5 is perfect. Old rules were 3. was okay.

In Dr. D. Brownstein's book "Iodine, why you need it why you cannot live without it" he mentions a way to detoxify. It seems that if we do not absorb iodine--or, if you get symptoms of iodine sufficiency (watery nose, excess saliva, frontal headache, tiny lesions on upper body), it may not actually mean that you have enough. It may be because our iodine receptors in our cells are clogged with fluoride and bromide (as they mimick iodine). You need Iodoral pills or the equilavent amount of Lugol's-- 50mg a day taken all at once with your thyroid med (if you take it). It flushes out the fluoride and bromide. I tried this, the first 4 nights I sweat like pig. I continued the 4 Iodoral pills for one month. I feel great now.

Even if you absorb (which I did), I think this is good for you. Try the Iodoral for a week - one pill a day- -to make sure it agrees with you first. A rash means an allergy. By the way, you only absorb 12% of what you paint~~the rest goes up in the air...it's a halogen. Publication #4 at www.optimox.com explains why some doctors are afraid of iodine, it was a faulty study-- one study and our health was sacrificed!

ix-nay the natural thyroid meds and add wheat grass juice for energy and a shot of Aloe Vera juice for skin and hair. Incidentally the wheat grass is great for hair as well. As you improve work with your MD to come off anti depressants they will only add more symptoms eventually. Hope this helps it did me. Sara

I was told by a Pharmacist that there are Iodine receptors in every cell of the body. This would make iodine relevant to much more than just the thyroid gland.


Iodine Deficiency
Posted by Susan (USA)

The classic sign of iodine deficiency is an enlarged thyroid gland. Some people with hypothyroidism develop an extremely large thyroid, known as goiter. Today, iodine deficiencies in the United States and other developed countries are rare because table salt is supplemented with iodine and crops in developed countries are generally grown in iodine-rich soil. In developing countries, however, where soil is often low in iodine, more than one billion people are estimated to be at risk for disorders caused by iodine deficiencies.

Uses
Iodine offers a variety of potential therapeutic uses, primarily in the prevention of hypothyroidism. A health care provider may also recommend iodine supplements for the following conditions:

Fibrocystic Breast Changes

There is some evidence to suggest that hypothyroidism and/or iodine deficiencies may contribute to the development of fibrocystic breast tissue. People with fibrocystic breasts experience tenderness, particularly just before menstruation. Certain foods may worsen breast tenderness such as caffeine (including from chocolate) and high fat foods. During a physical exam, the doctor can feel cysts and fibrous (hardened) tissue. A review of clinical studies found that iodine replacement therapy (particularly for those with low levels of iodine) may improve the tenderness associated with fibrocystic breast tissue. The women taking iodine experienced very few side effects.

Iodine deficiency has also been associated with ovarian cysts, breast cancer, thyroid goiter and hypothyroidism. Recent work in the field of iodine deficiency has shown that replacement therapy decreases the risk of breast cancer and promotes the reversal of fibrocystic breast disease.

Vaginitis

Many women with chronic vaginal symptoms use over-the-counter preparations such as iodine to relieve symptoms. Iodine, used as a douche, may reduce vaginal inflammation as well as the itching and discharge that go along with this health condition. Povidone-iodine has the advantage of iodine without the disadvantages of stinging and staining.

Douch for vaginitis: generally two tablespoons of an iodine solution to one quart of warm water once per day. Douching should not be done without first consulting your healthcare provider.

Wounds

Iodine is commonly used as a topical treatment for wounds. Ointments containing iodine are frequently used on burns to lower the risk of infection.

Dietary Sources

Iodized salt is the primary dietary source of iodine. Plant and animal sea life, such as shellfish, white deep-water fish, and brown seaweed kelp, absorb iodine from the water and are great sources of iodine. Garlic, lima beans, sesame seeds, soybeans, spinach, Swiss chard, summer squash, and turnip greens are also good sources of this mineral. Bakeries may also add iodine to dough as a stabilizing agent, making bread another source of iodine.

FOODS THAT PREVENT THE BODY FROM UTILIZING IODINE

Foods that prevent the body from using iodine are: turnip, cabbage, mustard greens, cassava root, soybeans, peanuts, pinenuts and millet. These foods are called goitrogens and excessive consumption can cause goiters. However, cooking usually inactivates goitrogens.

Available Forms of Iodine

Sodium iodide (iodine) is available as part of a multivitamin/mineral combination or as a topical treatment for wounds.

Precautions

Sudden, large doses of iodine may impair the production of thyroid hormones, causing hypothyroidism temporarily in someone with otherwise normal thyroid function. Excessive iodine intake can also increase the risk for other thyroid diseases such as Hashimoto's, Graves', certain thyroid cancers, and thyrotoxicosis (a dangerous condition due to an excessive amount of thyroid hormones in the bloodstream). For these reasons, iodine supplementation is not recommended for people who live in areas where iodine levels are sufficient.

SEAWEED DOSAGES

11/24/2006: Our Bangkok contributor Ted writes, "Iodine is taken when you suspect you have a deficiency. But it is not taken everyday at all and often it is taken once or twice a week. Only when you know you need it. Seaweed contains both iodine and bromine, which generally means you can't overdose on iodine. The reason is simple: bromine displaces iodine. But when bromine and iodine are present together, it makes for iodine bioavailability, while bakery products high in bromine will displace the iodine. The interesting thing is when bromine and iodine (found in nature) as in seaweed are found together, once the body doesn't need iodine it can easily be removed due to the presence of bromine. I have not seen any case of excess iodine consumption from taking of seaweed, but I have seen quite often excess consumption of iodine when they are added in the salt and taken too much. The reason is nature presents us with many minerals in their respective ratios and their antagonism preventing such an overdose and allowing the body to achieve greater equilibrium. This issue appears to be consuming foods from natural rather than chemical if you fear of any possible overdose. Ted"

I plan on starting the Borax treatment- I have RA, allergies, An Autoimmune disease. Whatever.

6 mo ago, I started iodine therapy- did whole protocol- salt, vit. B's, everything for my thyroid. I gained 25 lbs! in 1 month. This is not an exaggeration. I cannot get it off. So I am hoping the Borax will get rid of the chronic fatigue etc. I had no BO on the iodine but I sure plumped up. Any idea why? Especially since it's supposed to help the thyroid, which is why I had put on weight before and had no energy?

Sorry to hear about this; given the age of your post, perhaps things have normalized....

My thought was - what type of salt you were using. If a natural, unrefined salt like Celtic, you should be fine...but if processed, that may have caused the problem. Just a thought.

Hello.

My question today is for Bill. I was wondering what your thoughts are on nascent iodine vs lugols (potassium iodide). Pros/cons?

I found tree/plant Iodine/Potassium supplement on barefootherbalistmh site and very impressed. I am taking it with "worms be gone" tincture for a month now. There is passion in these products, passion for herbs, plant and its healing qualities. If you decided to supplement with Iodine, I recommend you look into these supplements.

Hello I am looking for Lugol's Iodine in Alberta, do you have a location here where I could purchase it?

Where to Buy: Canada
Posted by Toourlady89 (Hayward, Ca) on 04/01/2014

You could purchase Lugols Iodine from Amazon in different concentrations..

FYI: if you will be using Lugol's internally, there is a protocol of vitamins here on this site to follow to safely take iodine without untoward side effects..


Where to Buy: Canada
Posted by Bess (Calgary, Alberta, Canada) on 04/01/2014

Hi Val from Innisfail - I get 5% Lugol's from London Drugs or Shoppers Drug Mart (you need to ask the pharmacist to order it for you). Mary from Saskatchewan recently mentioned a number of Calgary compounding pharmacies that carry it as well (in stock so it doesn't have to be ordered). I don't know if Innisfail has a compounding pharmacy but if there isn't, try any pharmacy. You may want to talk directly to the pharmacist (sometimes the assistants aren't as helpful).

Also, Bill from San Fernando said that Lugol's can be purchased at the vets and some pet shops in Canada.

Hope this helps - good luck! Bess

To Ted or anyone who can help me with this question, I would like to know as I have been reading on Iodine it says that Vitamin C cancels out Iodine. So if I need Vitamin C then must I give it up in order for the Iodine to help me? Any help would be appreciated. Thank you to Ted and Earth Clinic for being here for us.

Iodine Interactions
Posted by Mike62 (Denver) on 03/10/2014

Lin: Animals make a lot more vitamin c than people get. They also require iodine. The conclusion that can be drawn from this is that vitamin c does not cancel iodine. Maybe isolated c supplementation causes this. A 200 lb. mans tissues become saturated with c from whole foods at 200mg. After this c is no longer absorbed. C from whole foods depletes at 8%/hour. Freeze dried wild harvested acerola cherry powder has 17% c along with co factors when the product does not contain fillers.

Thank you Mike62 because of your helpful answer I went back and re read the article. I realized that I had totally misread it and they simply meant that they shouldn't be taken together. The article I read was: Iodine Remedies: Secrets From the Sea.

Bill from San Fenando, Philippines: Thank you so much for your very clear and concise answer, it helped me understand it so much better. My friend Jackie is worried about taking lugol's iodine and I wanted to know if taking liquid kelp would work just as well? Thanks for all your help. We would be lost without you and earth clinic, I have learned so much from the good people on this site.


Iodine Side Effects
Posted by Anne (Midwest) on 01/18/2014

My doc said that I'm hypothyroid, and rather than put me on Armor (which she is willing to do), she suggested that I try iodine supplements. I had a bottle of Iosol, and I have been taking one drop of this in water, for about 3 -4 days this week. I felt nothing, until yesterday while in line at the local store. Whammo! A wave of dizziness swept over me. Thankfully, today is Saturday so I can hole up at home and try to recover. I stopped the Iosol, have been drinking lots of water w/ lemon, taking B-complex and plenty of vita C, but still have some waves of vertigo if I move too quickly or duck my head too quickly. Has anyone else had weird dizziness when taking Iodine drops? Thanks to you all!

Iodoral Iodine
Posted by Ecfan99 (USA) on 12/29/2013

Hello - I have been taking iodine for over a year to help with goiter / cysts on thyroid, as well as fibrocystic breasts. I had been taking 75mg of Lugol's. About two months ago I switched to Iodoral because of ease of taking, and the Lugol's was staining my teeth. I started at 50 mg of Iodoral and didn't notice any detox or side effects. I bumped up to 100 mg a few days ago. I take the companion supplements as well (magnesium, selenium, C, B, sea salt).

Throughout the night last night I woke up feel very nauseated. Still feeling pretty queasy today. So much so that I've canceled my plans for the day.

Could this be the iodine doing further detoxing, and more halides being released into my system? I have taken some sea salt in water this morning, and may continue to do that. Just want to be sure I'm approaching this correctly. Thanks.

Ecfan99: Like a world class symphony that has excellent musicians and finely tuned instruments in the proper ratio, the body requires dozens of nutrients and hundreds of co factors to function at peak performance. Cooked regular food and isolated supplements do not provide these. The best nutrients come from raw, organic, grass fed, soaked, sprouted, fermented, and wild harvested whole foods. I was like you a short while ago. Today I am a lot better.

Skin Cancer
Posted by Judy (Australia) on 09/29/2013

hi... Fascinating to read about the iodine. I use petty spurge for bccs (basal cell carcinomas). It grows here like a weed. its actually called Euphorbia Peblis. The sap kills off any cancer cells.

I've dealt with at least six to eight bccs on my upper chest and face over the years. I only have very small scarring to cope with now.

The trouble is, you can't use it near your eyes as it can blind you.

My son has just had bccs removed from his lower eye lid. He had to have the eye lid completely removed and reconstructed. It was upsetting to know that I couldnt treat the area because of its proximity. He has had major surgery, and had to have two surgeries to get it right.

Is iodine just the one you can buy over the counter? is it toxic to the eye? it could be another way of getting around using something on the face to get rid of cancers.

Every time I take one drop a day of iodine from seaweed for a few days, I start to feel congestion in my chest. Could this be a cleansing reaction and if so what is the best course of action for improving my lung health? I am physically active and have a strong cardio vascular system.


Iodoral Iodine
Posted by Rsw (Uniontown, Oh) on 03/29/2013

Hi Bill, I started taking Iodoral a few times a week after reading how valuable it is. My doctor told me not to take more than one tablet a day or it would "blow out" my thyroid. Now I find I have hypothyroid. I am in the process of using Armour thyroid supplement at 30 mg. , with the intention of increasing it every 6-8 weeks until my TSH is 1. I bought some kelp capsules to take instead of the Iodoral. But after reading your article, I wonder if I should take the Iodoral again? We are going to monitor the thyroid nodules in a year for increase instead of doing a biopsy now. From what I've read, there is only a very small chance of a cancer that is aggressive in these cases, and many are diagnosed with papillary cancer but there is no increase in mortality, indicating either a cancer that is slow growing and not harmful or an outright misnomer. In order to stop the growth of the nodules, however, it seems to me to be important to increase iodine. Is this correct? Should I wait to see the effective Armour dose first, or take the iodine and probably get a good effect on a lower dose of Armour? I read a book on this but I'm still not familiar with all this. Thank you for any advice you may have.

Iodoral Iodine

I do believe you on the T3 & T4 testing. But unfortunately, last month when I went to retest my TSH level, I mentioned to the doc that I wanted to test the T3 & T4 also. Actually, I tried to demand that they test it, stating that the TSH level is an incomplete indicator of the thyroid. She wouldn't hear such talk. She said something like - no, this is how we test. And acted as if she'd never even heard of the other tests! They are "the authorities", and will not do what a patient asks if it's not in their agreeable scope of "knowledge".

With my TSH level just inside the normal range, they would definitely not do any further testing.

And being on the state health-care system, I do not have a choice of doctors, nor could I ever afford a doctor that I would actually intentionally choose myself. So I only go to the doc minimally, like for a blood test or an asthma inhaler.

Any suggestions on how to get the proper tests done for an affordable price, without a referral? (I'm in southern California).

Thanks for all that info and links, even though I wasn't the one who asked. (I'll continue to eat Brazil nuts for selenium, but do I need to eat a few every time I take a drop or 2 of Lugol's? Also, there's no knowing whether the source of the nuts is depleted or not. So might it be better to take a supplement on and off?)


Iodoral Iodine
Posted by Rsw (Uniontown, Oh) on 03/31/2013

Thank you, Bill, for all the useful links you have given, and also the info on Armour. In reading "Solved:The Riddle of Illness" by Stephen Langer, MD, which was recommended to me earlier, it seemed to say a lack of iodine could cause nodules, so I was confused as to why I would avoid iodine if the goal was to reduce or maintain what is already there. I will continue with the iodine and the other supplements, as explained. I am so surprised to see how many illnesses can occur as a result of low thyroid. Ohio has the lowest level of Selenium in it's soil, which can apparently lead to cancer, so I will be eating a few Brazil nuts daily, too. Thanks so much for all you do to help people everyday, and for answering my questions so I can understand the answers.

Hi, TQVM [Thank You Very Much] for the posts on EC. I was informed of some benefits of seaweeds but there are many types of seaweeds. Seaching 'seaweeds' on EC gave interesting readings but there no specific topic on seaweeds.

Are all seaweeds have the same benefits ? Especially those found in South East Asia and those in Europe ?

Thank you for sharing your opinions and experience on seaweed.

I've been taking Lugol's steadily for about three or four weeks - slowing building. I'm at six drops of 2% per day. Also taking C and selenium. Experiencing some symptoms, and am wondering if the intense menstrual cramps I am feeling today could be related? Thanks for any insight.

I'm taking the iodine for my thyroid nodules and fybrocystic breasts, by the way.
