You have probably heard of the importance of essential minerals such as magnesium and selenium for staying healthy and vibrant at any age. But how much do you know about iodine?

The fact is that iodine is utilized for just about every function in your body. Yet many people are unaware of their body’s need for iodine, and that iodine deficiency has reached epidemic proportions worldwide.

10 Important Iodine Benefits

Here are 10 reasons why maintaining sufficient iodine levels is an absolute MUST for your health:

#1. Iodine Is Necessary for Metabolism and Thyroid Function

Metabolism is the act of converting food into substances your body can use. Iodine is an important part of this process. It helps the body break down food into nutrients via the thyroid gland and other mechanisms. Iodine is the literal “fuel” for the thyroid. Triiodothyronine (T3) and thyroxine (T4) are the main hormones that the thyroid produces.

For these hormones to be created, they need iodine. Good thyroid health also helps your body keep a steady heart rate, regulate temperature, improve digestion, and maintain a healthy weight [1].

#2. Iodine Helps Your Brain Stay Sharp

Iodine deficiency has been linked to cognitive decline in countless studies and is one of the “world’s most prevalent, yet easily preventable, cause[s] of brain damage,” according to the World Health Organization [2]. Iodine deficiency during pregnancy has been linked to autism in a recent University of Arizona study [3].

Furthermore, a 2013 Australian investigation published in the journal Frontiers in Neuroscience found that iodine supplementation improved the perceptual reasoning of slightly deficient children considerably [4].

#3. Iodine Protects the Body From Toxins

Fluoride, chlorine, and bromine are dangerous chemicals found in everything from new car interiors to tap water. They can also severely hinder thyroid function. Maintaining healthy iodine levels can block these “halide” chemicals from accumulating [5].

Iodine can also protect against xenoestrogens – “chemical mimics” – that can lead to reproductive conditions like ovarian cysts and uterine fibroids [6]. Some experts, such as author and natural health advocate Dr. Mark Sircus [7], point to the possibility that iodine may also help with mercury detoxification.

#4. Iodine Protects You From Radiation

In addition to flushing the dangerous “halides” mentioned above, iodine can also protect you from radiation exposure. It is a natural protectant from UV radiation for the eyes, according to a 2004 Austrian study [8].

Iodine supplementation can also be used to help individuals suffering from long-term radiation exposure. The effects of too much radiation can happen because of accidents, medical devices, and the radiation emitted by TSA scanners at airports.

A 2008 study [9] published in Radiation Research discovered that “terahertz radiation” like that found in airport x-ray scanners is linked to genetic mutation. Adequate amounts of iodine in the body is a must for anyone who travels a lot.

#5. Iodine Is a Natural AntisepticIodine is a Natural Antiseptic

Maybe you remember that brownish-red solution your mom used to apply when you had a cut? For everything from cleaning wounds to purifying water, iodine is a sterilizing substance that can kill unhealthy organisms, bacteria and viruses.

A 2015 Iranian study found that a low-concentration iodine antiseptic used after oral surgery helped instigate first-stage wound healing in the surgery area, leading to faster recovery and less chance of infection [10].

#6. Iodine Is a Powerful Antioxidant

According to some experts [11], iodine may be as powerful in this regard as vitamin C! It can help reduce free radical damage that may lead to gene mutation and disease. It is a great boon for the immune system as it helps clean the blood of harmful pathogens.

A 2013 meta-analysis [12] published by the National Autonomous University of Mexico (UNAM) in the journal Thyroid found that iodine is “an antioxidant as well as an antiproliferative and differentiation agent” which can help clear up free radical damage in many organs of the body. It is also a powerful anti-inflammatory.

#7. Iodine Ensures Reproductive Health

Did you know that Japanese women have the lowest rates of breast cancer in the world? A 2003 report published in the journal Breast Cancer Research postulated that this could be a direct result of eating iodine- and selenium-rich seaweed, which is a staple in the Japanese diet [13].

Iodine is fuel for reproductive glands as well as the thyroid. Studies suggest that getting enough iodine can help prevent fibrocystic breast disease, preeclampsia, ovarian cancer, ovarian cysts, vaginitis, polycystic ovary syndrome, and even breast cancer. Enough iodine in the body is also one aspect of a healthy pregnancy [14].

#8. Iodine Helps Prevent Hair Loss

Besides protecting the skin and eyes from UV radiation, adequate levels of iodine can give your skin and hair a healthy glow. This is because iodine is involved in cellular rejuvenation [15]. Healthy iodine levels also help prevent hair loss because of the nutrients supplied to the thyroid gland [16]. Iodine in combination with other essential minerals such as iron, magnesium, and zinc can be a powerful internal tonic for thinning hair.

#9. Iodine Maintains Strong Teeth and Bones

Iodine assists in the production of strong teeth and bones by being a key player in calcium absorption. In fact, the connection between low iodine, low calcium absorption, and hypothyroidism has been known by researchers for at least the last hundred years [17].

One of the functions of the thyroid is the production of calcitonin, a hormone which helps balance blood calcium levels. This mechanism not only leads to maintain strong bones; it also plays a role in healthy functioning of the nervous system, heart and muscles.

#10. Iodine Helps Stabilize Your Mood

It is well known that low iodine levels can have an impact on the brain, as mentioned above. More recent research has also linked iodine deficiency to depression and anxiety. A 2004 study conducted by German researchers and published in the Journal of Psychiatry and Neuroscience [18] found a link between “alterations of thyroid-stimulating hormone (TSH) and mild cases of depression and anxiety.”

TSH is produced by the pituitary gland to signal the thyroid to produce more thyroid hormones. Fluctuations in TSH are often an indication that the thyroid is not getting enough iodine to do its job [19].

How Can You Get Enough Iodine?

Odds are you are eating many whole foods, which already contain iodine. Among these are seaweed, high-quality seafood, eggs, strawberries, cranberries, dairy products, and dark green leafy vegetables. Sadly, because of poor soil quality and other factors in our toxic world, this may not be enough.

A study conducted by Royal North Shore Hospital in St. Leonards, Australia, found that 74% of healthy adults may not be getting adequate amounts of iodine through diet alone [20].

In addition, holistic health experts agree that relying on iodized table salt to get the right amount of iodine is not a wise option. This is because in order to produce commercial salt in the cheapest way possible, today’s manufacturers rely on harsh chemicals, which eventually wind up sprinkled on our dinner plates [21].

When it comes to iodine supplements, choose only the best.

Keep your standards high when it comes to iodine supplementation. Remember that iodine is the food of the thyroid, and the thyroid is the “command center” of all your hormones! You wouldn’t put junk into your mouth to feed your body, would you? Don’t put it in your thyroid either!

Iodine deficiency is widespread, not just in the U.S., but also globally. The World Health Organization estimates that roughly two billion people worldwide suffer from some form of iodine deficiency [22].

Don’t be another statistic. Stand out from the crowd by enjoying all the amazing health-supporting benefits that iodine can provide!

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. Interesting comments…I was hyper also, and I am wondering what Anne said, “ what is missing.” My hair has never come back to normal and everything else seems to be leveled(TSH) as far as I can tell. I plan on trying a iodine supplement liquid, as it was recommended but will add the black cumin since I have some.

  2. In March of 2023, I was in an accident, and developed a leg infection. Subsequently I had developed MRSA. I was hospitalized three different times. I was given 40 bags of Vancomycin intravenously. After I got out of the hospital I started taking the "Game Changer" Nascent Iodine. I can't tell you how much this supplement has brought me back to good health!

  3. Those alleged dr.s make buckets of money only as long as you are sick!!! They have worked hand in hand with "Pig"-Pharma for decades perfecting their lies of how much your body "requires" this and that!!!

  4. I have been taking your iodine drops for a long time as my blood test were always borderline with my thyroid function. Both my grandmother and mother took thyroxin due to low levels. I am 70 and glad to say healthy, fit and full of energy. Just one question! I usually buy three bottles or more at a time but as it’s only 3 drops they last forever and I just noticed when I opened my last bottle it is out of date by a couple months! Should I not use it? Can iodine go out of date? Thanks

    • Hi Yvonne,

      Thanks for your question.

      Organixx Iodine is good for 2 years from the manufactured date.

      The first thing to note is that the stamp on the bottle is a “best by” date, not the product expiration date.

      Our products carry a “Best By” date on them. This means the product is still at its intended level of potency on that date before it naturally starts to wane.

      Organixx plans for a long shelf life in the manufacturing of our products as all supplements will begin to lose potency at some point. That is just nature taking its course. However, because the potency level diminishes at such a very, very, very slow rate, it is our recommendation to utilize our products up to one (1) year beyond the “best by” date as the nutrient value of the product remains viable and usable.

      If you buy our products in bulk and would like to store them properly for extended use, we recommend that you do not refrigerate supplements unless the label advises you to do so. To store your supplements properly, we advise that you keep them in a cool, dry location away from direct light and heat.

      We hope this helps and wish you a happy & healthy day.

  5. If i haven't noticed any improvements after taking iodine for close to a year, should i increase my drops? Also, you stated that meds should be taken 4 hrs apart from iodine. Does that include supplements as well? I'm assuming so. Great informative article!! Thanks much.

    • Hello Sue, Thank you for your questions. When it come to dosing outside of the recommended dose we ask that you speak with your doctor to find the correct dose for you. Everyone has different needs and tolerance levels. Our Iodine is formulated to be taken alongside any of the Organixx supplements. Have a wonderful day! :)
