Supplementing With Iodine? Make Sure It’s the Right Kind for You!

Iodine is absolutely essential for every function in your body, including immune function, cardiovascular health, and metabolism. Of course, it’s most instrumental for the thyroid, since iodine is the foundation for thyroid hormone production.

According to the American Thyroid Association [1], close to half of the U.S. population suffers from lack of energy, temperature dysregulation, cognitive impairment, metabolic irregularity, and other conditions consistent with insufficient iodine intake.

The fact is that most of us need more iodine in our bodies. But what kind of iodine is right for you?

Iodine in Salt: Goiter Prevention and That’s About It

You may find it hard to believe that Americans and the rest of the world are so deficient in iodine. After all, you may think, don’t they put iodine in table salt?

It’s true that most people in the U.S. and the world get most of their iodine through salt. This poses more than one challenge, however. The first issue with consuming iodine from table salt is that you will not get enough.

The addition of iodine to the U.S. salt supply started in the 1920s in response to a government health mandate. During that time, up to 40% of the population of the upper Midwest and Great Lakes region suffered from goiters and other thyroid diseases caused by extreme iodine deficiency [2]. [Note: a goiter is an enlarged thyroid gland that results in a swelling of the neck.]

Adding iodine to table salt did help with the goiter epidemic, but that was about it. Nonetheless, it became the foundation upon which the U.S. RDA, or Recommended Daily Allowance (now called the Recommended Daily Intake, or RDI [3]) was built. Today, the RDI for iodine is 150 mcg/day for an adult and 220 mcg/day for a pregnant woman. This amount may stop goiters, but it’s not enough for all the iodine needs of the body.

Toxins in “Iodized” Table Salt

The second issue with table salt is the amount of toxins that are in it. This concern was not present in the 1920s when the mandate began, but has become a reality in the age of cutting corners for safety and health in the name of big profit. While salt in the 1920s still came from the sea or mineral deposits, today’s “iodized salt” is actually a man-made form of sodium called sodium chloride (with iodide added to it).

In order to make salt white and help it last longer, most manufacturers use a bleaching process. This adds dangerous halides such as chlorine and bromide to the mix, which block the body’s absorption of iodine. In addition, other chemicals are often added to the salt, including manufactured iodide, sodium solo-co-aluminate, fluoride sodium bicarbonate, anti-caking agents, and aluminum derivatives [4].

If you are going to sprinkle salt on your food, most health experts suggest Himalayan pink salt or Celtic sea salt, which contains trace amounts of naturally produced iodine as well as other essential minerals.

Is There Iodine in Food?

Okay, so if you can’t rely on table salt to provide you with enough iodine… what about the iodine in food? Long before there were supplements, people the world over were eating enough of the right kind of foods to get the iodine they needed, correct?

If you look at the situation from a historical perspective, this is absolutely true. Foods such as seaweed, sea food, fish, eggs, spinach, dairy, strawberries, and cranberries [5] have a high iodine load when compared to other foods. In the past, eating these foods with iodine would ensure healthy amounts of iodine in the body.

Zoom in on the last 20 years or so, however, and you will see a completely different picture. The depletion of nutrients in the soil, as well as an increasing toxic load, has changed the amount of essential nutrients available in the foods we eat.

Here is a case in point: In a multi-decade study, researchers at the University of Texas analyzed the nutritional components of 43 different vegetables and fruits grown in the U.S. between 1950 and 1999. The report, published in the Journal of the America College of Nutrition [6], discovered “reliable declines” in essential vitamins and minerals in 1999 compared to 1950 samples.”

Potassium Iodine in Tablet Form                

Iodine in tablet form comes in gel caps, pellets, and pills. For the most part, they are concentrates of dried kelp sources or similar substances. Molecularly, tablet form iodine is potassium iodide (KI), sodium iodide, molecular iodine, potassium iodate, sodium iodate or sodium iodine, or some combination of these.

Potassium and sodium are often part of the picture because they act as carriers for iodine that the human body can safely absorb. Iodine in its natural state is unstable and even dangerous. Scientists discovered a while ago that combining potassium with iodine to form potassium iodide can create a more stable form, which can be absorbed by the body.

Molecular iodine, sometimes found in tablet form, is absorbed into the thyroid at a low rate but into breast tissue at a high rate. This makes molecular iodine a go-to for many who wish to help prevent breast-related conditions such as fibrocystic breast disease and breast cancer.

Researchers at Queen’s University Department of Surgery in Ontario, Canada, state in a report for the Canadian Journal of Surgery that “[the] results indicate the superiority of molecular iodine over iodides when treating fibrocystic breast disease [7].”

Research also shows that while potassium iodine cannot prevent radioactive iodine, or iodine-131, from being absorbed into the body, it can block its uptake into the thyroid immediately after high exposure. As the writers of Harvard Health, a publication of Harvard University, explain: “By flooding the body with non-radioactive iodine, the pills keep the gland from absorbing the radioactive iodine [8].”

KI is a very stable form of iodine, so by flooding the system with it right after exposure and over the next 24 hours, the thyroid gland can become “full” and will not take in any more iodine, radioactive or otherwise. This mechanism is why the World Health Organization [9] currently has protocols in place for “Iodine Prophylaxis” right after nuclear accidents. The main threats of events like Chernobyl and Fukushima is that when reactors leak, they will continue to spill radioactive Iodine-131 as well as cesium-137 into the environment for years after [10].

The downside regarding potassium iodine for everyday use is that only about 20% of this kind of iodine can be assimilated by the body.

Alcohol-Based vs Glycerin-Based Iodine

You may have noticed that some iodine supplements come in liquid form. These liquids are usually created by using either alcohol or glycerin.
The advantage of using a liquid for iodine transport is that it becomes more bioavailable to the body. Iodine in alcohol, however, is not the preferred method of liquid transport for several reasons.

First, most alcohol used for supplements are simple ethanol or grain alcohols, the same kind that the bartender puts in your favorite martini. Because of this, alcohol-based iodine may not be appropriate for young people, pets, those with high blood sugar, or those recovering from alcoholism.

In addition, almost all alcohols are made with genetically-modified corn and are not something you want to consume daily if you are striving for a healthy lifestyle [11].bottle-of-glycerin

On the other hand, glycerin (also known as glycerine, glycerol, or glycerite) has many advantages – that is, if you can find the right kind. Most commercial glycerin-based products, like commercial soaps, are sourced through animal products. A better option is vegetable-based glycerin. And the best of all is organic, non-GMO glycerin that is not made from soy or corn.

Organically-derived, vegetable-based glycerin has many advantages for both external and internal use. Unlike alcohol, which is a drying agent, glycerin retains moisture and does not evaporate in air. Glycerin can be a great salve for burns and is an antiseptic as well. It won’t upset blood sugar levels and, as a boon, iodine in glycerin has a much longer, more stable shelf life.

Nascent Iodine

Nascent iodine is also known as atomic iodine, monatomic iodine, Atomidine, or colloidal iodine. The term “nascent” refers to iodine that has an incomplete number of electrons. This gives it an electrical charge, according to a report conducted by the non-profit Weston Price Foundation [12] and others.

Nascent iodine’s charge is what makes it uniquely special. Many forms of dietary iodine break down into iodide in the digestive tract. In this state, iodine-dependent organs like the thyroid and reproductive organs cannot use it. The charge of nascent iodine helps it stay intact and absorb quickly and thoroughly into the organs that need it most.

High-absorption is most helpful for the thyroid because nascent iodine can help this important gland maintain homeostasis. A balanced, properly-working thyroid ensures that that the body is operating with overall vitality, health, and strong immune function.

Which Iodine Supplement Is the Best for You?

Iodine is perhaps the most important nutrient for your body to ensure total health. For the health of your thyroid, and every organ, make sure you are getting enough highly-absorbable, organic, nascent iodine every day.

You may have deduced by now which form of iodine is the absolute best for day-to-day consumption. That’s right: a nascent iodine in a non-GMO, organic, and vegetable-based glycerin solution carrier [13]. You can get all of this in Organixx organic Iodine.

When your organs are working hard to detoxify, you want the purest form of iodine possible to help them work more efficiently. It only makes sense to use an organic form that’s totally natural and free of chemicals. Organixx Iodine is one of the only formulas that is USDA Certified Organic. It’s a pure, nascent form of iodine which your thyroid can use immediately.

  1. My wife (Thai) has many cysts in her breasts which are uncomfortable for her. She has read about molecular iodine, but we haven’t found where to buy it even on line.
    Can any one help? We are based in Thailand.

  2. Good article. But I have been searching for an article that can say the advantages/disadvantages or using either nascent iodine vs ionic iodine. When I wasn’t working for a while, I could not afford your nascent iodine so started taking a cheaper ionic iodine. Cannot find any concrete comparison of the 2 to see if I should switch back.

    • Hi Maureen, thank you for your feedback. We are glad to know that you found this article informative.

      Unfortunately, we do not have a material that discuss about ionic iodine.

      However, we do have a few articles about Iodine that you might find interesting:

      We hope this helps. Wishing you a lovely day!

  3. I am a big fan of iodine and in particular Organixx Nascient Iodine. I began taking potassium lodide which did resolve polycystic breasts but tended to trigger the Hasimoto’s. Canada has very few options when it comes to quality iodine products. I began taking Organixx’s Nascient iodine a couple of years ago. Pleasant taste for iodine. I take mine with a little water in the evening with selenium and other supplements. Taking it straight was too hard on my mouth.
    I forgot to take it for a few months recently and slowly the goiters increased in size, and symptoms of hypothyroid began to creep up. I was almost out, so re-ordered and since resuming the products, have begun to see improvements again. My body needs iodine and I love that I can take such a healthful product. Thank you Organixx

    • Hi Linda, thank you so much for your feedback!

      We are glad to know that you have seen positive results from using the Organixx Iodine. We appreciate you sharing your health story with us!

      Thank you so much for choosing Organixx. We wish you the best in your wellness journey!

  4. All very informative to read the comments. I am awaiting the arrival of the Iodine I ordered and hoping it will improve my health. In the comments there have been requests of adding selenium but not one of the questions have been answered.
    Please let me know if I should add that to my daily dose of iodine?
    Also hope there is no weight gain in taking this supplement.

    Thank you for your reply.

    • Hi Ellen, thank you for your support and recent purchase with us.

      We’re sorry if you weren’t able to find the answer to your question in the comments. We’d be more than happy to address that for you.

      Our unique form of Organixx Iodine does not need co-factors due to its nascent atomic form, however, there are several vitamins and minerals that can aid absorption and potentially improve the overall benefits of iodine.

      Selenium and magnesium can improve absorption of iodine in individuals who are known to be deficient or have known malabsorption issues. Other vitamins and minerals that can assist in the overall function of iodine after it has been absorbed are B-vitamins, vitamin C, and manganese. The necessity of taking additional vitamins and minerals with iodine should be discussed and recommended by a trusted healthcare professional.
