Lugol's Iodine Supplements

Last Modified on Apr 10, 2015

What is Iodine?

Iodine is one of earth's elements, part of the halogen group and a purple liquid at room temperature. It is also a common first aid treatment for cuts and to make water potable. Furthermore, it is a health supplement commonly found added to table salt in order to prevent iodine deficiency, which can result in goiter, developmental delays, and other health ailments. Iodine is also to be found in certain medical supplements.

However, supplemental iodine is most popularly taken in the form of Lugol's Iodine, a liquid solution of iodine and potassium iodide (KI). If your mother ever painted one of your wounds with iodine (or when you gave blood), it was most likely Lugol's Iodine applied to your skin in order to prevent infection. Various concentrations of Lugol's Iodine exist (1%, 2%, and 5% iodine solutions with a larger part of potassium iodide in water). While generally safe for application and consumption in proper doses, iodine can irritate soft tissues such as in the throat and stomach. Iodine will also stain skin and fabrics.

Lugol's Iodine for Thyroid and Other Health Issues

Goiter is the classic health ailment treated with Iodine, along with other thyroid issues such as Grave's Disease and Hashimoto's Thyroiditis - cautiously in the latter case. Both hypothyroidism and hyperthyroid conditions are said to benefit from supplemental iodine at very different dosages. With Lugol's Iodine, the standard supplemental treatment is to "paint" a 2-inch square patch of skin with the iodine solution and allow it to be absorbed into the skin. You can reapply once the stain has disappeared.

[YEA]  I am happy to say that I have had fantastic results with using The Lugol's Iodine for my acid reflux. I have suffered for years with this ailment and I have had so many prescriptions and special diet restrictions. I can't believe all this time I have been iodine deficient and that was the cause. I took a few drops a day and slowly built up my dose, taking a few days off here and there. After a couple of weeks I realized I was doing better and about a month later I haven't had any problems with my stomach at all. I have had problems with stomach aches since I was a child. This is revolutionary for me. I am telling absolutely everyone about it!

[YEA]  Hi, I'm a Chiropractor of over 22 years. I want to add a cure that I got from reading Dr. Donsbach, D.C.

My wife and I found as we got older that we were both starting to have digestive problems and really bad acid reflux at nite. The wholist concept is acid reflux is due to NOT ENOUGH acid! You can confirm if this is the case by taking a tablespoon of ACV when you are getting it, if it stops it, then you are LOW in acid.

The next step in the wholistic approach is to take digestive enzymes and HCl to substitute for the low acid. I always thought this isn't getting to the root problem of WHY isn't the body producing enough acid anymore. This is where Dr Donsbach came in.

He discussed that the body needs IODINE to produce the stomach acid. That made sense in that since becoming a Vegetarian, I don't get much seafood and I keep my salt intake down.

So I ordered Lugol's Solution from Amazon and began taking 2 drops a day in a glass of warm water first thing in the morning on an empty stomach, monday through friday with the weekend off. My wife did the same. Sure enough within a few weeks my digestion is back to where it was as a teenager, and acid reflux is gone! My wife had the same results as well as a friend that tried it.

If you go to take the iodine, first make sure you aren't allergic. I think a drop on the inside of the wrist or arm and see if it gets swollen or itchy, is a good test. After that, if no reaction, then you can start with one drop in water and see how that effects you. If you have no problems then you can proceed to the 2 drops.

I've been trying to get this information out there, because when people take antacids and medicines that decrease acid production in the stomach, it greatly limits the bodies ability to digest the food,and starts a process that ends up greatly harming your health.

If the word can get out about this cure, it will help millions to improve their health for less than a penny a day and prevent them from ruining their health as they are trying to help it.

Good luck and please write your feedback here so others can see.

Best wishes for health and happiness,
David from H.B.

[YEA]   I can't believe I've stumbled upon this! I have been experiencing severe "heart" attacks and stabbing pains in my neck...long story short, had the gastro and Ecg checks done, Ecg is 100% clear, got a rx to treat GERD but chose not to get it cos my integrated practitioner advised against this and suggested Betaine Hydrochloride to increase acid levels, Digestive enzymes, Probiotics and Lugol's Iodine for thyroid issues and reflux. Unfortunately, I haven't followed it in this way, will surely do now!

Thank you very much David! (David (Huntington Beach, California, USA) on 01/04/2009)

I have Sjogren's Disease (Syndrome) and am drying from the inside out, particularly afraid it will dry my internal organs. I have very dry mouth, and severely dry eyes right now, and I don't want this to progress. I am wondering if you are still having good luck with this 2-3% solution 3X/day? Are you using Lugol's? If not, what brand are you using and can I get it without a prescription?

Thanks for any help you can give.

Andrea; I have used a natural remedy for over twenty years-called black cohosh, it has been a God send for all these years. As for dry eyes, it's just the greatest, it also supports the whole system. Black Cohosh can be bought in most any drug stores and some of the leading stores.I thought I would add an extra alternative for many others to use. Good Luck...

Iodine has wonderful health benefits and you must take the companion nutrients along with it in order for it to be beneficial -- otherwise you will most probably have health problems. It is imperative to add this information and information on the salt loading protocol to the main description of iodine on this earth clinic site, to avoid people having problems with iodine and perpetuating the myth that iodine is bad for you. Please, if you have privileges to do that, do your research and add information on the the hyper-importance of the companion nutrients and salt loading to the description of iodine.

The companion nutrients are: selenium (200 to 600 micrograms); magnesium (400 - 600 milligrams); Vitamin C (3,000 to 10,000 milligrams); 1/2 teaspoon unrefined salt per day. If a person has autoimmune thyroid disease they would add Vitamins B2 and B3 - 100 mg riboflavin and 500 mg niacin, 1-2x per day. (People with autonomous nodule (toxic nodule) of the thyroid should not take iodine, so it is important for people with thyroid nodules to find out if the nodule is caused by Graves' Disease or a toxic nodule (Toxic Multinodular Goiter) -- see Grave's remission case report on

If you want to avoid the flush from niacin (the flush is not a health problem, but some people prefer not to experience it), then go with the niacinimide form (inositol hexanicotinate); stay completely away from the "timed release" or slow release forms of B3 as they have caused problems.

Iodine, which is very good for health, is in the same category of elements as bromide, chlorine, and fluoride, which are toxic to the human body. This category is called halogens -- they all go to the same receptors in our cells. We are surrounded by the toxic halogens, contained, for example, in our water supply and in things like flame retardant on mattresses. If a person has toxic halogens stored in their cells, when they take iodine, the iodine will begin to displace the toxic halogens, kicking them back into the bloodstream, and then the kidneys will excrete them through the urine. If the toxic halogens start hanging out in the bloodstream for a while before the kidneys can excrete them, they can cause a whole host of detox symptoms, so it is important to know that taking half a teaspoon of unrefined salt in 8 ounces of water, followed immediately by 12 ounces clear, filtered water will help the kidneys flush the toxic halogens right away (the sodium binds with the halogens). See for the salt-loading protocol as well as a list of bromide detox symptoms and iodine-literate practitioners. This is one reason why some people get confused and think they are "allergic" to iodine -- they take iodine without companion nutrients or without doing the salt push should they experience bromide detox.

One way to avoid detox symptoms altogether is to take one drop of 5% Lugol's solution per day, along with the companion nutrients, for one week. The next week increase to 2 drops per day, and so on, until reaching 16 drops per day, which is 100 milligrams of iodine. Another way, which I am less familiar with but which is described at, is to start right away with 16 drops of Lugol's 5% (100 milligrams iodine) or iodine in pill form, per day. Some people have experienced freedom from asthma using that dose. See curezone for that info as well as the other conditions that have iodine has affected positively. It can take quite a while at 100 milligrams (or more) per day to reach a state of iodine sufficiency. The length of time it takes depends on how ill a person is, for example it might take 6 months for a healthy person, or 3 years for someone with cancer. Once sufficiency is reached, the protocol is to drop down to a maintenance dose of, say, 50 mg per day.

Good sources of information on iodine are (lots of medical articles),, which has a free download guide to supplementing with iodine, and the iodine yahoo group. offers iodine testing.

[YEA]  I use Lugol's iodine anytime I am getting a cold. I was a chronic user of antibiotics because of asthma. I have not had a bout with bronchitis because anytime i am getting a cold or virus I put 6 drops of Lugol's in water 3 times over a 24 hour period and the infection is gone. I actually have one day colds now. I follow up with acidophilus for my stomach and milk thistle for my liver. This really works and probably will work for Bird flu if you keep a supply in your cupboard.

Converting Lugol's to Milligrams   0  0   

Posted by Jolole (Beaconsfield, Tasmania, Australia) on 07/11/2013

I have researched for hours the information re iodine benefits and also checked the contributions on earthclinic site where I found the conversion table for the various strength of Lugols iodine in mgs. I bought online a bottle of Lugols and the label states as contents: purified water, 10% Iodide, 5% Iodine. The conversion table mentions both 15% and 5% of Lugols, which one do I take to converse to mgs ?? I have started with 1 drop in glas of water daily, but also read that this might take a year to really improve my health. I have used it now for 4 days, have no problems digesting it and wonder how many drops or mgs I can take with this product. Can anyone help out here. Blessings and good health to all.

Hi Jolole from Beaconsfield, Tasmania, Australia - Here is what Bill (very knowledgeable in these things) posted awhile ago:

02/13/2012: Bill from San Fernando, The Philippines replies: "There seems to be some confusion over the use of Lugol's Iodine. What people tend to always forget is that the drop dosage of say 50 mgs of 5% Lugol's Iodine per day is completely different from the same 50 mg drop dosage from say a 2% Lugol's Iodine solution. A single drop of 5% strength, Lugol's Iodine -- where one drop contains 6. 25 mgs iodine -- would be about 8 drops. A single drop of 2% Lugol's Iodine would therefore contain only 2. 50 mgs of Iodine. So to get a 50 mgs dose from a 5% LI solution would be only 8 drops, whereas a 50 mgs doasage from a 2% LI solution would require 20 drops(2. 5 times more).

To help clarify this, here is a table that shows total Iodine content per drop for different % strengths of Lugol's Iodine:

Hope that helps! Cheers, Bess

Hi Bess, I had seen this table but not certain if the product I bought was 15% or 5% iodine. It was advertised as a 15%, but I now assume that the % only relate to the iodine part. This would mean that I have a 5% solution. Is that correct? Thanks and blessings.

Hi again Jolole from Beaconsfield, Tasmania, Australia - Sorry I misunderstood your question (I'll blame it on the heat! ).

Your bottle is a 5% solution [5% solution consists of 5% (wt/v) iodine and 10% (wt/v) potassium iodide mixed in distilled water]. I use a 5% solution also and that's what's on my label. Since I'm hypothyroid, I take 2 drops every morning in water which works out to be 12. 5 mg daily. Cheers, Bess

Hi Fats1964...The amount of iodine per drop would also depend on what percentage strength lugols iodine you are using(which you never mentioned). For example, if you're using 5% LI then the amount per drop would be 6.25 mgs. But if you are using 2% LI then the amount would be 2.50 mgs iodine per drop.

For the full range -- see the drop to mgs table in this link.

2. After taking it, what are likely side effects/ adverse reactions if any?
3. No distilled water here. Rain water OK?
4. Take the drops before eating or after?
5. How do I tell if cadmium, mercury, fluoride, chlorine etc. have left me?

Lugo's iodine caused my heart to palpitate (and not in a good way; the bad way). So I thought no more Lugo's. I felt bad because I read the health benefits on this site and others and I could not take even one drop. Then while reasearching fatty acid metabolism I found that you use a lot of vitamin B-1, B-6 and B-12. All the of these B's have heart palpitaions as a sign of their deficiencies. So I took all three. Now I can take Lugo's. Yeah!

Also selenium and zinc deficiencies can cause heart palpatations. So if you can't take iodine because of the heart quivers you might have a deficiency you need to correct first.

[YEA]   I get heart palpitations when I drink coffee or tea. It's the caffeine for me. So I add a bit of organic BLACKSTRAP MOLASSES to my coffee. That prevents me from having heart palpitations. BSM contains several minerals, which coincides with your theory that heart palpitations are as a result of a mineral deficiency.

Hi Diane...In answer to your question -- it really depends on what benficial action you want from the lugol's iodine.

Ted rightly advises that you should take lugols iodine (LI) with vitamin C on a health basis. Taking it like this beneficially increases the electrons or negative onductivity in your body and therefore increases the alkalinity of the body with many other attending benefits from vitamin C. Now I'm going to get a bit technical to show you another benefit of this mix. LI consists of molecular iodine plus potassium iodide in water. But if you add drops of LI to vitamin c in solution then the molecular iodine will all converted to iodide and that's why the solution goes clear. Not only that, but the molecular iodine oxidizes some of the vitamin c and converts it to dehydroascorbic acid(DHA). This is highly beneficial because DHA is absorbed into the body more quickly and in much greater amounts than ordinary vit c or ascorbic acid. What's more ordinary vit c cannot penetrate the blood/bone or blood brain barrier whereas DHA can.

The main reason for taking LI on it own with just water is to supply both the molecular ione form and the iodide form to satisfy your whole body's daily need for iodine/iodide. For example, the thyroid can only absorb the iodide form whereas a woman's breasts(and some other organs) need to absorb it in the molecular iodine form. Every cell in the body needs and uses iodine/iodide. Therefore, in this instance, if your whole body(incl. thyroid) is iodine deficient then you should take just the Lugol's Iodine Protocol shown here.

Just finally to also clarify the myth where some people still actually believe that all you need to do to heal iodine deficiency in the thyroid is just to take small doses of the iodide form. But what many people tend to forget is that if their thyroid is deficient in iodine then their whole body will also be deficient in iodine/iodide as well. Remember that every cell in your body needs and uses iodine/iodine. To illustrate the importance of this -- the thyroid needs to store about 50 mgs of iodine per day for proper operation. The rest of the body(excl. the thyroid) needs to store about 1500 mgs of iodine per day to remain healthy. That means that the rest of the body needs to store 1500/50 = 30 times more iodine than the thyroid. And so if you think of your low iodine problem as just being purely a thyroid problem then I'm afraid that you will have missed the boat entirely with your own thinking. So if you do have a thyroid problem then you should logically always act to satisfy the whole body's need for iodine/iodide as well.

This post seems so intelligent & thorough. Thank you!

My sole issue was comment suggesting to take along with asorbic acid, because it states at 1/2 dozen+ websites: NOT to take the iodine within 20 minutes of Vit. C.

I'd really like to see someone knowledgeable address this disparity, because I just started a 1 drop daily morning regimen which I carefully time to wait 1/2 hour to take my vit c afterwards. (which I used to just mix directly in my morning coffee/tea, along with turmeric, etc. And a pile of everything else! :-) Decades including kelp and red algae, so now I am very confused.

Does that mean I never got the iodine from latter because took same time as Vit C? This is a person who also loves her seaweed in soups, beans, etc.

Yet my iodide patch disappears within hours. Comments welcome, many thanks again!

Thank you again!

[YEA]   Your liquid iodine I am assuming is Lugols Solution. Vit.C, more properly known as ascorbic acid, reacts immediately with elemental iodine in a redox reaction that changes some or all of the elemental iodine into iodide. The issue is not that you lose all benefit by mixing with Vit.C, since the iodide form is used by some tissues, like Thyroid. But you lose some or all of the elemental iodine form when you mix Lugols with Vit.C, and, in turn, you lose some or all of the benefit of the elemental form in that dose that is apparently required or preferred by many tissues, such as breast, ovaries, and prostate. BTW, Kelp acts as a seawater filter and picks up relatively high concentrations of toxins, including arsenic, which is why it really is not a good source of iodine.
