Iodoral Review - Does This Iodine Supplement Work? Is the lack of proof a deal breaker?

Editor's Review: 3.0 / 5.0
Iodoral Review

There are numerous reasons individuals may have difficulty losing weight, or maintaining a healthy weight. One of the more common reasons is an under or overactive thyroid. The makers of Iodoral, Optimox Inc., claims their product can help these individuals. However, they also claim the product can assist anyone who needs help losing weight. We were eager to learn more about the product and the associated claims.

EDITOR'S TIP: Combine Iodoral with a proven fat burner such as Leptigen for better results.

What You Need to Know

Iodoral is essentially an iodine supplement. The primary purpose of the product was intended to provide supplemental iodine to the thyroid in order to promote better thyroid function. A properly functioning thyroid helps facilitate weight loss and can give individuals more stamina and energy. While it originally began as a health supplement for a different condition, there is a great deal of anecdotal evidence suggesting it is an effective weight loss supplement.

A 90 count bottle costs $26.00, however, it is typically sold in 90 or 180 count sets. This seems like a reasonable price for a weight loss supplement, but read on…

How does the thyroid affect weight?

One of the main claims made by the makers of Iodoral is that it helps increase production of the thyroid gland. Several studies have indicated that iodine deficiency can lead to hypothyroidism. By increasing the amount of iodine in the diet the problem is typically resolved. Hypothyroidism has many negative impacts on an individual’s physiology, including weight gain, fatigue, difficulty concentrating, and reduced energy. By stabilizing thyroid production many of these negative impacts can also be eliminated. However, iodine must be used in conjunction with Vitamin A in order to impact the thyroid. Vitamin A is not one of the ingredients in Iodoral.

According to our research editor, “Even if the iodine was being delivered with the Vitamin A, the person taking the supplement would most likely only benefit if they had hypothyroidism.”

Scroll below for one of the best products we’ve seen over the last year.


The two main ingredients in Iodoral are both iodine based.

The Science

While there is a link between increased iodine in the diet and improved thyroid function in patients with hypothyroidism, there is absolutely no clinical evidence that those individuals with normally functioning thyroid glands would benefit from additional sources of iodine. While the company does supply anecdotal evidence of consumers who have lost weight while taking the supplement, there is no way to know if this was because they had an underlying medical condition, or if the results were achieved through diet and exercise and the supplement wasn’t a factor.

The Bottom Line

We like that Iodoral is all natural and has minimal ingredients. The science supporting iodine and improved thyroid function is valid, but this supplement doesn’t include the needed Vitamin A to guarantee efficacy. Additionally, since there is no scientific evidence supporting the claims that the product promotes weight loss, we simply can’t recommend it.

The best weight loss supplements rely on more than anecdotal evidence to support their claims. Rigorous testing and a robust money back guarantee make us feel more confident in recommending products.

One of the best examples of this we’ve seen is Leptigen. The company offers excellent guarantees and provides detailed information about the research that went in to making the product.

The makers of Leptigen are so confident their product will deliver on their claims that they provide new customers with a special trial offer. We have had many readers pleased with this show of faith.

Iodoral is an iodine supplement manufactured by Optimox Inc., an online-based manufacturer. Iodoral's only purpose is to supply extra iodine to the thyroid gland, which they claim increases thyroid function. Increased thyroid function leads to more stamina and weight loss, according to several studies. Iodoral was originally intended to be an iodine supplement, but over the years it has evolved into a weight loss supplement. Unlike other diet supplements, Iodoral is all-natural and contains only two ingredients, both iodine-based.

Available online for $26.00 per 90ct bottle, Iodoral is normally sold in standard 90ct bottles or 180ct bottles. The manufacturer only offers a 30-day money-back guarantee for unopened bottles. Numerous testimonials attest to Iodoral's effectiveness, but there are no studies conducted on Iodoral itself. Iodoral is taken twice daily for the best results.


Iodine, Potassium Iodide.

Product Features

Iodoral claims that iodine helps increase thyroid production, which is partially true. Numerous studies show that iodine deficiency leads to hypothyroidism; an increase in iodine usually soothes the problem. Hypothyroidism itself is the leading cause of weight gain and causes many side effects, such as decreased energy, chronic fatigue, and loss of concentration. Eliminating it removes all side effects and allows the person to function better. However, it is important to note that iodine must be paired with vitamin A to actually work within the thyroid. Nevertheless, some testimonials back up Iodoral's claims, touting weight loss of up to 50 lbs. Iodoral is only effective if there is an existing iodine deficiency, however - and too much iodine will harm the thyroid.

There are also some side effects not listed with this product. Acne is mainly associated with increased iodine consumption, a very unpleasant side effect. Despite these concerns, however, Iodoral is decently priced at $26.00 per bottle. It is one of the more affordable supplements on the market today.

  • Studies show that iodine cures hypothyroidism, a leading cause of weight gain.
  • Iodoral is based on all-natural ingredients.
  • Iodoral is one of the cheapest supplements available.


  • Iodoral is only safe (or effective) for people with slow or inactive thyroids.
  • Iodoral has few features that facilitate weight loss.
  • Iodoral must be paired with Vitamin A for it to work properly.
  • You can only take Iodoral until your thyroid functions normally.


Iodoral itself is not an actual weight loss aid --- it is a nutritional supplement. Although studies show that increased thyroid production aids in weight management, this only applies to people with hypothyroidism. There are several inherent dangers associated with Iodoral, so it's best to discuss it with a doctor before using it. Nevertheless, Iodoral is an all-natural supplement that is worth looking into if you suffer from thyroid trouble, but do not begin using it without the guidance of a licensed physician.

    Tell us your thoughts about Iodoral.i have been taking iodor for a couple weeks now and just noticed bruising on my legs! Small brown spots! Could this be due to the iodor all? Thx

    Hey jody, if when you stop taking Iadoral it continues we suggest contacting a doctor for your safety.

    I have taken Iodearal low dose, and found it aided with weight loss. However, Ii since learnt that it is important, ideal first, or at least simultaneously to address adrenal fatigue . boosting thyroid function when adrenals are badly fatigued can make you feel worse. I found it best to address the two this way.


    Your Name Jimmy G

    I was the king of sinus infections. I have been taking Iodoral for 4 years @ half 12.5 pill a day, and haven’t had any flu, sinus or ear infections or sore throat. I breath clearly @ my nose is never stuffy either. It also helps me focus better @ I have a little more energy. The yellow in my toenails is also gone. My mood is also better and rarely do I have explosive behavior anymore. I’ll be on Iodoral the rest of my life!

    Today I was so puffy and go on the scale and couldn’t believe the water retension. I done with this product.. I am Hypo



    If you are having trouble with water retention try taking a supplement that is just Potassium. Take one 3X’s a day at first then move up to 2 3X’s a day. My doctor prescribed this for my best friend and it worked great. She was amazed.

    I have not been taking Iodoral for over 8 years. I have never retained water. The Iodine tells my T3’s and TS’s to work. The T3’s tell the T4’s to produce more. My thyroid just stopped working period. My doctor has me on Iodoral and Nature Thyroid. This keeps my T3’s and TS’s up above normal but the T4’s are still at the bottom of normal.

    I am currently taking 50 mcg of lev0thyroxin in am on empty stomach. I did see a little improvement and the test for TSH 3rd GEN (not sure what the test means) was 2.2102 value on the last blood test.
    I want to start taking Iodoral and my doctor is not ok with that, do I still need to take the script of Lev 50mcg along with Iodoral? Please give me some insight on this matter.



    I take 130 mg of Nature Thyroid. I was also taking 1 tablet of Iodoral morning and night. My TS and T3 levels were raised significantly but my T4’s stayed the same. I am pregnant now and only take one in the morning. The normal for a T4 is .8 to 1.8. This is the one I have found seems to matter the most. I can tell a difference in my energy levels when I forget to take it. This was both before and after getting pregnant.

    I am interested in taking Iodoral as a preventative supplement. Should I do this without having the checks done?


  • 7

    It cause my potassium levels to go so high I had to go to the emergency room!


  • 8

    Can I take Iodoral if I’ve been diagnosed with Hashimoto’s. I take Synthroid 75mcg.


  • 9

    I need to know if Iodoral is a safe alternative to Armour?


  • 10

    I was using Ioderal with a small dose of Synthroid and my T-4 was a little above normal and TSH went down to .11 – very low. Then my doctor agreed to take me off the med’s and then my TSH went to 22! Very high! Is it wrong to take Ioderal without taking thryoid? I thought it was a supplement that so I didn’t need med’s. After my glands started to get swollen with difficulty in swallowing, he put me back on meds. Can I take ioderal by itself?



    you never stop taking the synthetic pill just because you are taking a iodine form. You can gradually decrease the synthetic pill (under dr. supervision). Might want to talk to your dr to replace the synthetic pill ( which has only T4) with Armour which has more hormones ( T4, T3, THS, and other nutrients). Be careful with getting high dose of Iodoral. There are pros and cons about this if you google…Good luck

    Has anyone who has taken Iodoral suffered from acne breakouts? Thanks for any info!!

    I would like to know why it has been said that Iodoral shold not be taken if you suffer with autoimmune disease.I was just about to try it, when I read the above comment. I have been diagnosed with Schmidt syndrome. Multi autoimmune diseases including Hypothyroidism which I have been diagnosed for 20+ years.



    I am also auto Immune do to my Celiac Disease. I am not sure if it the same. However, My doctor has had me on Iodoral for 8 years now. I have a holistic doctor. I also take 130 mg of Nature Thyroid. I’d ask your doctor just incase. I haven’t heard that you can’t take it if you have are auto immune.

    I am not hyper or hypo, but I have a behign thyroid nodule (goiter and its pretty big) and the guy in the healthfood store said that this would get rid of it. Any input?


  • 14

    i have been on the iodoral since march. needless to say, while it started off doing wonders for me, as soon as i got to 2 pills, twice a day, i started having problems. as of last week, at my last TSH test, my thyroid has stopped functioning and i am on the de-tox program for the iodoral.

    if small dosages are working for you, please do not increase that dosage. i wish i would have just stayed on the 1 pill twice a day. i AM on doctor care – i go to a naturopath.

    this is day 5 of NOT being on it, and my nerves are shot.

    take care everyone.

    Yes. I take a thyroid hormone medicine & have since I hit puberty; now in my early 50’s want to know if I should try taking this Iodoral as a supplement& or with my Synthroid medicine. It goes up & down. Started out hyperthyroid then to hypothyroid. It seems to be basically on a borderline scale-then from there goes up some or down some. Tests get expensive too. Thankyou, Bev


  • 16

    Just want to say that if you have a family history, especially on your mother’s side, of Grave’s Disease, you shouldn’t take this supplement at this high dose. I was hypothyroid, my doctor prescribed IODORAL and it triggered Grave’s Disease. This is much harder to take care of then hypothyroidism. Just do your research or test your iodine levels before taking this.

    is iodoral used in the event of a nuclear disaster? Is this the potassium iodide that is distributed in an nuclear event? Will this protect the thyroid?


  • 18

    Can Iodoral be taken with Sotalol, a beta blocker?


  • 19

    Not sure if my comment went through. Research Dr. Jim Howenstine and Dr. Abrahams. They claim Iodoral works for both hypo and hyper and also for cysts and nodules. Basically they state all thyroid problems result from a lack of iodine.



    Dr.Williams did say if you are hyper or overactive and have autoimmune, taking iodine could be like pouring gasoline on a fire. There has been success with iodine for over active thyroid but make sure you do not have an auto immune disease.



    Thank you so much for the autoimmune notation as I have lupus and was considering taking this supplement! I really so appreciate it!

    Does anyone get frequent mood swings will taking Iodoral?



    If you get mood swings either lower the dose or stop taking it. This is a sign of having too much iodine. I had to stop while nursing my son because he was getting mood swings but, my daughter did not. So I continued to take it while nursing my daughter. This was under the supervision of my doctor. I have been taking it for 8 years now.

    I no longer have a thyroid gland, it was surgically removed and anything remaining was radiated. SHOULD I TAKE IDORAL?


  • 22

    Can you buy Iodoral at the local drug store?


  • 23

    Been *hyper*thyroid my whole adult life. Haven’t been able to get over 165 lbs for 20 – 25 years. After 3 weeks on Iodoral, I gained 10 lbs. Wow. I would disagree with your statement that Iodoral is only for people with slow thyroids. The more I read about iodine, the more excited I get.



    I’m encouraged by your experience. All I’ve read thus far is for under activity. My son is about to begin Iodoral for over-active thyroid.
    Any other info you could share?

    Christy Mitchell

    There was a lady who wrote the article about the side effects of Iodoral. She said to only take it if you have hyperthyroidism. She should have written Hypothyroidism. hyperthyroidism is someone w/ and overactive thyroid. I take Iodoral and it is for my hypothyroidim, (my underactive thyroid.)
    People may read this article and use Iodoral thinking it will help their overactive thyroid. She should read up on her terms before writing such and important article. Iodoral is readily available online w/o a prescription. Always check a 2nd opinion or article when making decisions if an article is correct.
