Best Thyroid Supplements of 2017

vector illustration of thyroid gland anatomy

The thyroid gland is responsible for regulating your metabolism, heartbeat, energy levels, muscle strength, appetite, health of your heart, brain, kidneys, and many other important bodily functions. If something is erroneous with the thyroid, a person will likely experience a lot of unpleasant symptoms, the most common of which is weight gain. Millions of people suffer from hypothyroidism in America alone. Due primarily to diet and genetic issues, the thyroid gland is not able to produce enough thyroid hormones. Thyroid issues often go undiagnosed since so many of the symptoms from low thyroid hormone can be mistaken for symptoms of other problems. This is where thyroid supplements come in.

Whether you have fatigue, weight gain, or full fledged hypothyroidism, it is likely you will need a thyroid supplement to help boost your natural thyroid hormone production. But which product is the best thyroid supplement? I remember about four years ago, I purchased a ‘thyroid support and weight loss’ supplement for $80 that was supposed to really help me. Instead of looking up reviews like a knowledgeable, independent consumer, I instead fell for a good marketed product that failed to deliver on its many promises. Hopefully, through this website and our reviews, you will be able to find the best thyroid supplement for your needs.

The most important aspect in determining the best thyroid supplement are the ingredients within the bottle and its quality. Although some manufacturers may have similar formulas, their thyroid supplements can have very different effects on the same person. This is due to the quality of the ingredients within the bottles. In many cases, the quality of the ingredients and where they are sourced from, can have bigger effects than the ingredients themselves. A manufacturer can talk and write about how the iodine within its supplement is the best, but ultimately 1mg of high quality iodine extracted from underwater kelp can have more of an effect than 10mg of one that is synthetically produced. Be sure to check out the list below to make sure you find a supplement that works best for your needs.

    Thanks! This is very helpful in learning what each thyroid supplement has inside it. I do have a question regarding thyroid supplements in general. I have seen some articles that are advising people to avoid them for a variety of reasons. What do you think?

      Hi Lynda,

      With most comments, I’ll end up replying in a couple sentences, but because this a question that I’m sure a lot of others have as well, I’m going to take some liberty here and write a decent amount about my thoughts on this topic.

      Almost all of the thyroid supplements we review on this site is relatively safe.

      They contain nutrients, herbs, minerals, and vitamins that you can find in regular diets and certain food. They just conveniently and accurately place them into capsules so that you can make sure your thyroid is getting all the support it needs to function in a healthy manner.

      However, there are thyroid supplements that some experts consider to be unsafe.

      These are most commonly supplements that contain crushed, raw thyroid extracts from bovine (cattle). The idea with these thyroid supplements is that the thyroid glands from animals contain some amount of T3 and T4 thyroid hormones. Thus, by ingesting these supplements, you are in turn taking thyroid hormones that can boost an under active thyroid.

      Please note that this is a very valid method of treating an under active thyroid.

      Some of the relatively popular thyroid medications on the market, such as Armour Thyroid, Nature-Throid, Westhroid, all work this way. They all contain naturally desiccated thyroid glands and many patients say that it works great for them. For some patients, it works a lot better when compared to other thyroid medications such as Synthroid/Levothyroxine.

      The controversy that arises here is the difference in regulation between supplements and prescription drugs.

      If you take a thyroid supplement that contains – lets say – 150mg of Bovine Thyroid Tissue, what does that actually tell you? You don’t know the exact amount of T3 and/or T4 hormones in each capsule. It is possible that one capsule contains very little T3 and T4, while another contains a lot of both, or somewhere in the middle, or a lot of one and none of the second, etc. Hopefully you get the idea of what I’m trying to point out.

      With prescription medications, it’s an entirely different story. Armour Thyroid, for example, contains liothyronine (T3) and levothyroxine (T4) hormones in about a quarter ratio.

      If the dosage is 60-65 mg of thyroid extracted and crushed from porcine (pig), then it contains 9 mcg of T3 and 38 mcg of T4. In essence, you can be sure of how much thyroid hormone you are consistently putting into your body.

      So I do think it is important to be weary of those thyroid supplements that contain actual thyroid hormones. It’s seems like a better idea to get those medications through doctors. But again, the thyroid supplements seen in this website, I do believe, should be taken to support healthy thyroid functionality.

      Hopefully this helps!

    What ingredient do you consider to be the most important or essential I guess in a thyroid supplement?

      Thyroid Advisor July 20, 2017 at 4:45 pm

      Hi Abby,

      I hate to take the cop out answer and say it depends on the person – but honestly, it does.

      The most important mineral, herb, vitamin, or nutrient in these thyroid supplements will be the one(s) that your body is lacking or is not getting enough of through your diet. Getting blood tests done can help figure out which nutrients you are lacking as well as figure out the values of TSH, T3, T4, etc. in your body.

      If you’re asking which vitamins and/or minerals were most lacking in individuals with thyroid disorders, I would have to say Iodine and Zinc, in that order. I would look for a thyroid support supplement that contains both of these.

        Followup to Abby’s question. Are there any ingredients we should avoid? Especially in a thyroid supplement?

        • Thyroid Advisor July 25, 2017 at 2:38 am

          Hi Ash,

          I would avoid calcium and soy. Calcium is especially bad if you are currently on thyroid medications, such as synthroid, as it can interfere with hormone absorption. See https://www.ncbi.nlm.nih.gov/pubmed/21595516 for more details and information about this.

          As for soy, it is a sort of controversial topic whether hypothyroidism patients should avoid it. Some experts believe they should, and others do not think it has much effects. Perhaps it’s better to stay on the safe side.

    I have been feeling a bit tired for the past couple of months. My doctor decided to do a thyroid blood panel test on me. The values came back within “normal” range, but they were on the lower side of that. I am considering buying one of these thyroid supplements and trying it out.

      Hi Savannah,

      Yeah, many doctors are hesitant to prescribe thyroid medications when patients return values in the “normal” range. The only options are finding another doctor or taking thyroid supplements.

      I think it could definitely help people in similar circumstances as yourself. I would be surprised if it doesn’t help in some fashion.

      Not really. They’re just like other supplements. Most of them recommend taking the capsules with meals, preferably breakfast.

      The most important aspect is to just be consistent. Take them around the same time everyday.

      Hi Elizabeth,

      With the better thyroid supplements out there, you should feel improvements and benefits by the second or third week at the latest. Most people say it is much sooner, though. It does depend on the person and the type of thyroid supplement that is being taken.

      For the lower ranked supplements, I suspect it would take a lot longer – if ever – for you to exhibit betterment.

      Hi Arianna,

      I believe I wrote a bit about this before – either that or I’m getting some deja vu. The formula is just one part of the puzzle and often times, what happens is that there will be a great formula but the extracts and source of the ingredients will not be the best kind of quality we want to be putting into our bodies. This is often the case with supplements – even those not in the thyroid health area – where some will have very similar formulas but will work a lot differently for similar people.

      Hmmm… I’ll look into it. However, that could take some time.

      It is definitely a good idea. Gluten and GMOs are known causes of hypothyroidism for some, so we would want to avoid those in our diet and supplements.

      Hi Gab,

      TSH is definitely high here, and T3 and T4 are lower than ideal. Depending on who your doctor is, they might put you on a low dosage of thyroid medication.

      As for your question – yes, I do think these supplements could help you as well. I’d recommend trying one of the higher rated ones on this website. Be sure to find one with a money back guarantee as well so you will not have anything to lose.

      I would be interested to know what your blood tests (extended as well) and levels some time after taking some supplements (if you choose to.)

      Hi Kellyanne,

      It’s always a good idea to check with your doctor before adding supplements to existing thyroid medications due to potential interference of hormone absorption.

      With that being said, it is not uncommon for patients, especially those with a low dose, to add a thyroid supplement to their regimen. If you do choose to take a thyroid supplement, be sure to take the supplement at least 3 hours after taking your synthroid to lower the potential for interference.

      I do think these thyroid supplements can help support your thyroid gland and its functionality. I would not recommend them otherwise.

      If you remember the thyroid supplement you took, I can maybe provide more information about why it was potentially ineffective. What likely happened, was that the marketing or hype of a brand did more than what was actually inside the bottle.

      Hi Gem,

      Usually, people who have confirmed in some way, usually through lab tests or consistent symptoms associated with hypothyroidism, decide to take thyroid supplements. In either case, you will still get the benefits of these thyroid supplements, if you decide to take them. It’s actually possible that you restore your thyroid by the time your appointment comes up (if its not for a couple months.) Your doctor can verify this at that time, or advise you on other options.

    I am currently taking a low dosage of synthroid due to my doctor’s diagnosis of subclinical hypothyroidism. I do not like some of the side effects, however. I am considering taking thyroid supplements as an addition or perhaps to eventually replace synthroid. What differences can I expect?

    • Reply
      Thyroid Advisor July 30, 2017 at 6:09 pm

      Hi Donna,

      Many patients do take synthroid along with thyroid supplements, like those on this page. A lot of them report feeling a lot better and energized with both. I haven’t heard of anyone feeling worse. It’s a good idea to consult with your doctor first, though.

      As for whether it can replace synthroid… I would usually say no – but if you’re on a very low dosage of synthroid, it might be possible. Obviously, every case is different, and for a lot of people, they will likely have to take synthroid for the rest of their lives. But it is also possible you are a perfect fit for thyroid supplements and end up rebalancing your thyroid.

    • Reply
      Thyroid Advisor July 30, 2017 at 6:32 pm

      Hi Marja,

      That article covered the main idea of what to avoid in some thyroid supplements: which was basically raw glandular extracts. Glandular extracts are a very useful treatment option (see our article on Armour Thyroid) but the unregulated nature of supplements often results in large fluctuations of hormones in each capsule compared to another one. Drugs like Armour Thyroid or Nature Thyroid produced in pharmaceutical labs are much better alternatives if you’re absolutely set on taking a pill with thyroid extracts from other animals.

      But, glandular extracts is definitely not the only thing to avoid in thyroid supplements. Calcium is another ingredient I would stay clear off – especially if you take synthroid or another form of levothyroxine. See this study on how calcium can reduce T4 absorption.

      Thyroid Advisor July 30, 2017 at 7:02 pm

      Hi Mia,

      You’re right that Vitamin A is needed by the thyroid gland to produce and synthesize hormones. It’s rare though we see them in thyroid supplements primarily because Vitamin A deficiency is super uncommon in the United States.

      It’s a lot more prevalent in third world countries. Diet in America, even though it’s not great, does cover Vitamin A well.

      But if you’re still worried about your Vitamin A intake, you can take another supplement that covers it specifically in addition to thyroid supplements if you take them.

      Hi Jenna,

      I believe what you or your doctor are referring to is: Current Good Manufacturing Practices or CGMP for short. Basically its a means of ensuring that the supplement meets a certain quality standard. All supplements made in the United States has to meet this bar according to the law. So, as long as the supplement is made in the USA, it should be good. Some manufacturers go above and beyond this standard as well.

      The quality is usually seen in the product.

      Haha, you’re right there’s no dumb questions. I’m sure someone else had a similar inquiry, but didn’t want to take the time to write a comment!

      Unfortunately, it does not work that way. If you take one of these thyroid supplements – especially ones on the higher end of the ranking – you’re already covering a decent amount of your bases in terms of nutrients, vitamins, minerals, and herbs.

      Taking another one won’t amplify the benefits – unless it contains an ingredient that the first one didn’t. You do occasionally see two or three different types of thyroid supplements from the same store or website. But that’s usually because the company behind it wants you to buy the “pack” of them at the same time so you end up spending more money.

    I am 74 years old and fall into a time when it was typical for a GP to Rx Thyroid medication for weight loss. Unfortunately I was only 10 or so pounds overweight and wanting to be a “Stewardess”as they were called back then. Well it didn’t work and nursing school was next. Soon learning that I was committed to taking it the rest of my life, and being a medical independent (not going to the doctor for simple advice) I managed my own dosages based on the way I happened to be feeling. So wrong, I know! What I did NOT know until 5 years ago was the importance of taking the medication on an empty stomach! Then, a short time ago read in some research material that green vegetables, flouride, chlorine, are just a few things that inhibit the natural production of this hormone. In moderation, any one of these wouldn’t matter, but I brush my teeth 4-5 times daily, swim for hours every week, not to mention I drink tap water, and every few days I cook up a mess of Kale, Collards, Spinach and eat a lot of them. All of these years my dosage never decreases, just goes UP, yet I am still the same old overweight, fatigued bag of bones! Oops, 6 months ago it struck me that empty stomach didn’t just mean food. I took all my pills and supplements at the same time each am. After years of mistakes in compliance and re-testing time and again, I believe I’m the best it’s going to be. Now, I’m well aware that you are completely appalled at what I’m telling you, but MANY people read reviews and I wish I had been informed 68 years ago. Hopefully, this may help someone else. I DO have a question, though. In the constant effort to be healthier, I made the switch from iodized salt to sea salts. Would this impact a healthy diet? (I do have an affinity for Nori which is a staple of Japan made out of seaweed. Our bodies crave what we are lacking-IMO?) I haven’t stopped brushing my teeth, have switched to salt water pools and cut way back on the leafy greens . Looking forward to your answer! Respectfully, Kathryn

      Hi Kathryn,

      Thanks for sharing your experience! Certainly a lot of information here, so let me try to address some of them.

      I managed my own dosages based on the way I happened to be feeling. So wrong, I know!

      Yeah, not the best idea, as you figured out later on! Thyroid medications (I assume you were on levothyroxine) take about 4-6 weeks to even begin to fully work within our bodies. So even if you were feeling worse or more tired one day, and decided to take an extra dosage, you wouldn’t feel the effects until much later. The fluctuations in dosages was also a likely factor in the energy, metabolism, etc. swings as time went on.

      What I did NOT know until 5 years ago was the importance of taking the medication on an empty stomach!

      This is basic information to anyone taking synthroid, but I guess since you were medically independent you didn’t have a doctor to tell you about this. A lot of foods can interfere with the absorption of levothyroxine – calcium, iron, even coffee (see our article on levothyroxine for more information – so a lot of patients end up taking it first thing in the morning when they wake up to avoid any potential issues. It seems that you found out about this information a lot later!

      Now, I’m well aware that you are completely appalled at what I’m telling you, but MANY people read reviews and I wish I had been informed 68 years ago.

      Hahaha, you’re kind of right. I guess for someone who lives and breathes thyroid information, my mindset is a bit different from most patients. It’s always great to see people’s experiences like this, because it reminds you that information you may consider basic, may be something that another patient has never heard of before. I’m sure a lot of patients were or even are in the same boat as you. I’m sure some of them will be able to see your post and experiences and benefit from it. Thanks for that. Onto your questions!

      In the constant effort to be healthier, I made the switch from iodized salt to sea salts. Would this impact a healthy diet? (I do have an affinity for Nori which is a staple of Japan made out of seaweed. Our bodies crave what we are lacking-IMO?) I haven’t stopped brushing my teeth, have switched to salt water pools and cut way back on the leafy greens .

      If you’re worried about getting fluoride while brushing your teeth, you can switch to a fluoride-free toothpaste. I’ve heard good things about Tom’s of Maine. Obviously don’t stop brushing your teeth!

      You don’t have to avoid all leafy greens – just cruciferous vegetables. See this link on which foods to avoid for the thyroid.

      If you switched from Iodized salt to sea salts, specifically Nori, it’s unlikely it will have a impact on your diet. Iodine is an important mineral for your thyroid, so you definitely need to get it in diet. Since Nori is made from seaweeds, which are rich in Iodine, it shouldn’t be much of a difference compared to Iodized salt.

    Hello,

    I have read all of the comments and love how dedicated you are to helping others with thyroid issues. I been taking 75mcg of Levothyroxine for the past year, not like I felt great on it anyhow, but unfortunately circumstances have it that I’m between doctors and will not be able to get a new one for a couple of months. I am looking for the best fit for supplement and any other supplements you would recommend for someone in this predicament?

      Hi Terry,

      If you have some recent lab test results, perhaps it could shed some more light on your condition. 75 mcg of Levothyroxine is a relatively low dosage to begin with, so perhaps it might be something to talk about with your doctor the next time you see him/her. They might have a reason, though, to start you on that.

      Generally, thyroid supplements can be combined with levothyroxine, and they can provide some benefits to the user. How much depends though, on the person, his current state, and the supplement type itself. The top ranked ones we have on this page would probably be better for you. It could be helpful too to check with your doctor if you have a chance.

        Thank you! I am in between doctors and just received the ThyroMate in the mail today. What I found interesting was that it is made with Soy. I thought soy wasn’t good for people with a thyroid condition?

        • Thyroid Advisor August 5, 2017 at 6:39 pm

          Hi Terry,

          Right now, soy is a bit of a controversial topic on whether hypothyroidism patients should avoid it. There is not really a consensus. Some experts believe soy interferes with thyroid hormone synthesis and absorption so people should avoid it, but others do not think it has any effect. While more studies are ongoing, perhaps it’s better to stay on the safe side for now and avoid it.

          If I remember correctly, because I did ask them about that too, I was told that there is very small amount of soy that is used in the processing of the minerals – about a tenth of a milligram – and very few, if any, soy proteins (which is what some believe may interfere with hormone absorption), that it is considered trace, and should not have any effect on the thyroid. However, due to allergy regulations, they had to include it on the label.

          You can ask them about it too, if you’re concerned.

    I am over 50 years old and my recent lab results have indicated that I almost have hypothyroidism according to my doctor. He says I have a slight problem converting T4 to T3 and recommended only diet changes now instead of starting on a drug. I have a followup appintment in the coming weeks. Can these thyroid supplements help and improve my results by then?

      Hi Abigail,

      I do think thyroid supplements can help improve your nutrient deficinces and support – in many ways – thyroid hormone production and conversion. We noticed that most of these supplements take about 2 to 3 weeks of consistent usage to really feel the effects of them. It does depend on the individual and the supplements, but I think that is the average that most should expect. If your appointment is in about a month, it definitely has the potential to improve your results. If it’s next week or even two weeks from now (as it will probably take you some amount of days to get a thyroid supplement either online or at a store), then probably not.

      I’ve taken quite a few of them. They are not at all big. Most are less than an inch in length and maybe half an inch in width and height? Definitely not something I, or anyone else I have talked to, would consider large by any means. Very easy to swallow in my opinion.

    I am currently living in London due to business and will not be back to the USA for some time. Do you know if it is possible to get the high ranked thyroid supplements on your list here in England? I heard good things of thyroid supplements from a friend of mine. I want to try them too.

      Hi Carlie,

      Unfortunately, I do not know the answer to that. This seems like a question the company you want to purchase the thyroid supplement from can answer or one of your country’s customs office.

      Some of these products are probably available on sites such as Amazon UK, like that can be an option for you as well.

    What is your view on glutathione? I hear good stuff about this, but did not notice it on your list. Also, thoughts on liquid versus capsule delivery of thyroid supplements?

      The first question you have is interesting.

      So, glutathione is an amino acid that the liver produces and acts as an antioxidant.

      I won’t go into all the benefits here – the gist is that it’s important. High levels of glutathione have been linked to better health while lower levels are commonly associated with a variety of diseases.

      Unfortunately, you cannot take glutathione through supplements or other forms of pills. I mean you can – but glutathione consumed orally, will be broken down in the gastrointestinal tract and essentially be ineffective.

      However, you can help boost natural production of glutathione through a good, balanced diet that includes l-tyrosine, Vitamin C, and riboflavin to name a few. Most thyroid supplements – at least the good ones – already contain these.

      As for your second question on liquid vs capsules. This is essentially a debate on which supplement form is the best. You have tablets, caplets, capsules, softgels, chewables, powders, and liquids, as you mentioned.

      There seems to be a prevalent idea that liquid supplements are inherently better because they can be absorbed faster, but research studies seem to disagree. Liquid thyroid supplements do have the potential of being absorbed faster, but not that significantly, about 10 – 20 minutes.

      There does not seem to have a difference in terms of nutrition intake either. It also helps sometimes to have the thyroid supplement dissolve over a longer period of time.

      Basically, most liquid thyroid supplements costs a lot more, and often contains fewer vitamins, minerals, and amino acids (due to space restrictions) than common, better thyroid supplements. Some of them taste terrible too!

      I do see an advantage for liquid supplements, however. For those who cannot swallow pills though, it seems like a great alternative. For most others, though, I would go with the regular capsules. Hope that helps!

    I used to take thyroid supplements almost a decade ago… can’t remember what it was called but remember it said it had the ashwagandha and ginseng herbs…really helped me a lot but ended up getting off of it due to the cost… thinking about starting back on a thyroid supplement… hope it works will let this site know.

      Hi Addison,

      Ashwagandha and ginseng are particularly helpful for thyroid health (see our article here on thyroid herbs). I’m not surprised you felt a lot better. Most people do!

      Hopefully, one of these thyroid supplements will have the same effect as that other supplement you took some time ago. Lets us know!

    Do you think people need thyroid supplements? I’m a bit averse to supplements in general. What other natural options are available for people like me?

      Hi April,

      Do people NEED thyroid supplements? Probably not. I’m sure they can survive without it, but I do think they help a lot. I’ve heard countless stories of people who feel like they got their lives and a bit of their youth back.

      But there are other options. Our article on boosting thyroid hormones and function naturally may help in this regard. I do think thyroid supplements are perhaps the best option for most, and they shouldn’t be disregarded without trying it, but you should always choose the option that works best for you.

    52 year old women. Developing a goiter on the side of my neck. It’s still really small if anything. Maybe just paranoid. What methods are there to help fix this? Thyroid supplements?

      Hi Stella,

      If the goiter is the result of nutritional deficiencies (commonly goiters are a result of low Iodine or Hashimoto’s), than thyroid supplements will help. It’s important to catch the goiter early though, as it seems that you have (by the way you should get it looked at my a doctor to make sure.)

      There are other natural ways of improving thyroid function. See this link here.

    I don’t have a question, but I di want to add that thyroid supplements have helped a lot for me personally. I was used to feeling tired and having low energy all the time, but didn’t know there was much I could actually do about it. After taking thyroid supplements for a couple months now, I feel very different. In a better way !!!

      Hi Shelby,

      I’m glad they work for you! I think a lot of people are in the same boat as you were in a couple months ago. Sharing experiences like these can help those who are still in the struggle. Thanks!

    Hi there,
    I’m looking for some advice.im a young male who trains at a high level (distance running) recently got a thyroid screen done and my t4 and t3 levels are far too low for optimal training and recovery. I’m looking into taking a low dose of NDT or one of these supplements. Would you be able to offer me your opinion which I should take based on my bloods.
    TSH: 1.9 uIU/ml
    Free T4: 0.8934 ng/ml bottom of range
    Free T3: 1.8 pg/ml bottom of range
    Total T3: 73.563 ng/dl low end of range
    Anti Thyroglobulin anti-bodies: 1.51 IU/ml
    Anti Thyroperoxidase anti-bodies: 0.24 kIU/L

      Hi Jack,

      I’m going to reiterate the main points of the response you received (through email) as it may help others who are in similar situations.

      You’re T3 and T4 levels are less than optimal – especially for an athlete. As for what to do from here. I would take a look at your diet and the kinds of foods you eat. If you’re diet is fairly good and if you take some form of supplements already, thyroid supplements may not be able to help you as much as others.

      NDT could help. It’s something to ask your doctor about, but you might have to go looking for one to prescribe you. In the sense that your tests are not THAT bad (when compared to others who have hypothyroidism), and you’re a young male. If you do take NDT, it will take a couple weeks for it to fully build it in your system.

      For the short term, I would look into B complex supplements and eating more (if you’re not overweight). They should give you the short term energy you need.

      Hope that helps.
