  1. Thank you, Cheryl, for your very informative article on the various thyroid medications out there. You answered many questions that I’ve had! ~Dr. Marta Adelsman, Life Coach in Communication and Consciousness

  2. Sounds like a great product. We check to see if it will be good for me. Thank you for keeping us informed as to what is available to us.

  3. Excellent article and I am so happy to learn about this new alternative! I have been on Nature-Throid for a few years now and was told, in November, by my doctor (who moved away 2 months ago) that I needed to go gluten free. The reason for this was she felt the gluten was causing my body to attack my thyroid. I have not been that happy with Nature-throid results (still have symptoms) even after an increased dosage. I had been giving thought to trying Armour Thyroid. I would love to try the Westhroid-P and see if it makes a difference. How do we proceed with this? I am in between D.O.’s right now and won’t see new one until June. I am in Indianapolis, IN. Thanks so much! PG&L, Carol

  4. thanks so much Doctor for this very informative article I am on Dessicated thyroid compound filled with sodium bicarbonate and need to take it 3 times in 24 hours doing fine I am hypothyroid with just my left thyroid the right one removed due to a large nodule I was wndering if I can switch to West Thyroid P (nocellulose fillers) and just take the medication once daily thank again

    • Hi Maria,
      Thank you for your attention to your health and inquiring about the thyroid medications. Any natural dessicated thyroid medication should achieve a steady state in your blood after a few days, and the blood test marker TSH stabilized in three months of constent dosing. Thyroid medications need to be taken on an empty stomach, and wait at least 30 minutes to eat in order to absorb the most from your pill. Westhroid-P is indicated to be dosed once a day, taken at a consistent time. It will provide a steady state in the blood and your tissues, so once a day is all that is needed.

  5. First I would like to THANK YOU so very much for such a wonderful thorough article on the medications for hypo-thyroid issues. I have searched for years looking for such info. Not sure why the “bots” found this article now but glad they did.

    I am currently on Armour and have been for several years (since 2008) and have always had issues with inconsistency and heart racing to mention two. I am going to try the Westhroid-P or the Naturthroid. My question I have read that there are compounding pharmacies that produce the medicine locally and are much better at keeping the formulas consistent. Is this ture in your experience and if so what are the names of ones you would recommend?

    • Hi Antoinette,
      I am glad the bots found this article for you, too!
      If you remember what I wrote about the actual amounts of T3 and T4 in these medications, you know they are very tiny, less than a grain of salt. Can you imagine working with such tiny amounts? I would prefer to leave the quality control of the measurements of these to RLC labs, since they only allow a 2% variation in amounts and test every batch.
      Compounding pharmacies are great, they do patients a great service. My mentor Dr. Alan Christianson and the author of the book I mentioned in the beginning, cited an incident where a patient was put in a life-threatening thyroid storm from taking too much thyroid medication due to a mistake by the compounding pharmacy. Once it is in your system, there is nothing you can do to get it out, only manage the symptoms of racing heart, and so on. Mistakes do happen, thankfully not very often. I would prefer not to risk it since there is such a great product from RLC labs.
      Wishing you health on your journey,
      Dr. Cheryl

      • Dr. Cheryl, until I read your comment about a compounding pharmacy and a patient’s “thyroid storm,” I didn’t know it had a name. It happened to me. Serious, painful symptoms plus an agonizing migraine had me doubled over for 4 days until I figured out what was causing it all. Even the surface of both palms and the bottoms of my feet blistered and peeled for weeks. I half imagine my heart did, too! (I had just gotten my thyroid refilled at a new compounding pharmacy, but didn’t suspect it in the beginning.) They would later explain that I probably absorbed more thyroid than usual because they used different fillers than the previous pharmacy… and this allowed for the “perceived” overdose. Who knows if that was the truth.)

        But here is the oddest symptom of all. Every trace of my ADD vanished for about two weeks. I came out of my chronic brain fog, had perfect memory, could think clearly, focus, and was exploding with unprecedented energy (both physical and mental). And I was WARM! For two glorious weeks, it was as though I was standing on a sunlit mountain top where I could see forever in all directions. Then, ever so slowly, I started descending back into the chill and fog. I wept more than once when I felt my world shifting back. The worst part about that incident is that it made me aware of what normal people experience every day. I stopped using compounding pharmacies, and until recently, have been with a ND who has me on Nature-Throid, which causes some allergic reactions. He also insists on treating my lab results instead of my persistent symptoms. I am glad to learn about WP which has no chemical additives.

  6. Dr. Cheryl, I would just like to confirm with you that the only “Lactose” free NDT is Armour, Is that correct? I have allergies of gluten, dairy, soy most often found in medications.

  7. I was so excited to read about WP Thyroid as I am concerned with the fillers that are being put into so many medications. I am currently taking Armour 15 MG & 30 MG each day because I need 45 MG of medication and there is not one pill available in that dosage. I, too, am gluten intolerant. Where can I find WP Thyroid? Do I need to go through my doctor or online pharmacy? Can you explain the MG dosage of this brand? I look forward to your reply. I will print your article & take it to my next doctor appt. Thank you so much! Lynn

    • Hi Lynn,
      Thank you for your interest in WP Thyroid for treating hypothyroidism. It was developed exactly for those wary of fillers in medications.
      WP Thyroid is a prescription medication, and must be prescribed by a licensed health care professional with the ability to prescribe medications.
      It is supplied in many dosages, in quarter grain increments. It looks like you are describing the Armour quarter-grain and half-grain tablets. WP Thyroid does make a three-quarter grain tablet.
      The manufacturer, RLC Labs does help patients find a prescribing physician in your area. Call them at 877-797-7997, but realize they might not have a complete list. Also check for licensed Naturopathic Physicians, because it is in our scope of practice in most states.
      In health,
      Dr. Cheryl

  8. Want to go more natural in low thyroid synthroid 100mcg. Please give me a list of doctors in the 91752 zip code.

    • Hi Jane,
      RLC Labs, the makers of Naturethroid, Westhroid, and WP Thyroid keep a list of doctors who recommend their products, and they can help you out. Please call them MST business hours at 877-797-7997.
      In health,
      Dr. Cheryl

    • Hi Sandy,
      The makers of WP Thyroid, RLC labs, maintains a referral list for doctors friendly to their products.

  9. Hi Cheryl:

    I took WP thyroid, RLC Labs, thinking it was totally pure. (This was well before I spotted your website). However, I’m quite allergic to pollen and ragweed. I have much later (after many welts), learned chicory isn’t recommended for use with pollen and ragweed allergy sufferers. I discovered this fact on Web MD, when doing my own research. RLC Labs unfortunately, doesn’t mention this anywhere in their literature.

    I called RLC Labs yesterday and reported this. I spoke to customer service who was shocked to hear my story. I asked to speak to a manager and she wasn’t sure who to funnel my call to so I am awaiting their return call. WP uses inulin from chicory as a filler.

    My body reacted severely to any insect bites with WP in my system. Inulin is also found in Chobani yogurts, certain fiber bars, certain cereals (Kashi), certain ice creams, and other foods. Thankfully, I don’t and won’t eat any of those. I will be reading labels even more carefully than ever going forward.

    Both my NP and local pharmacist were alarmed by this news but concurred with my finding. They ALL encouraged me to contact the manufacturer and said they would tell allergy sufferers they see not to use WP thyroid.

    I’m now going to be changing to Nature-Throid which has no chicory filler, but it does have more fillers. I do hope it works out well.

    The bug bite welts swelled up so much that they looked like huge spider bites. They have been horrifying! This went on for over a year. It started soon after I started taking WP thyroid, Neither of us saw any correlation. My NP was stumped just telling me to stay away from bugs. I used so much nasty insect repellent last year. I thought you and your readers may be interested in this discovery I finally made by connecting the dots. You can be sure that I am…..



    • Hi Lisa,
      Thank you for sharing your story. It certainly is highly unusual, from my experience.
      I am sorry you suffered those intense allergic reactions. It shows how hyper-reactive the immune system can become.
      That leads me to wonder about your adrenal hormone status, since that has to do with allergy and inflammation.
      All thyroid medication inserts warn against taking thyroid with severe adrenal problems, as it can make them worse. I cannot comment in your case, but I see lots of people who present with thyroid symptoms that need adrenal treatment as well. None of my patients had severe adrenal problems, but when the adrenal hormones were optimized by natural means, everything got better.
      You might look into compounded natural desiccated thyroid medications, as most compounding pharmacies can put the NDT into whatever medium you like. I talked to Wally Simmons from Women’s International Pharmacy and he said they mostly use olive oil as the filler so it is easily absorbed and hypoallergenic.
      Thank you for sharing your experience, as it may help others sort out any adverse reactions from inulin from chicory.
      In health,
      Dr. Cheryl

  10. Thank you for your kind reply, Dr. Cheryl!

    I do want to add that I used to get my NDT prepared through a compounding pharmacy. When I did, my body was quite happy. Where I live, they don’t use olive oil as a filler but they did use a filler that my body was willing to accept. I also don’t tolerate cornstarch well which was a typical filler this pharmacy used until I told them that I don’t do well with cornstarch either. The happy news is that I know that I can tolerate NDT.

    Unfortunately, my drug plan was switched after me taking that compounded preparation for several years. Under the new plan, it would only help me pay for a fraction of the $120 cost. This motivated me to switch to WP which my drug plan nicely helped me to pay for. Since I will likely be taking this medication for a number of years ahead (since I’m planning to living until AT LEAST 100 :^), I figured it was smart to try a cheaper NDT.

    Can you recommend the NDT called NP thyroid? My NP recommends that to her patients. I had opted not to take that originally when I switched as it too, has fillers, but not quite as many as Nature Throid. I also wanted to stick with RLC Labs as their products are highly recommended by Mary Shoman who is the thyroid guru online. In fact, I read that Mary takes Nature Throid. I will only go back to a compounded NDT if Nature Throid or NP thyroid doesn’t work out well for me.

    Also, a while back, I had my adrenals checked and I was told they were normal although as I recall, my cortisol level numbers looked somewhat low. I thought they looked a little low but my NP sounded like that was good and said nothing about them being abnormal as I believe they must have been in range.

    I truly doubt my adrenals have severe problems as my stress level is now low since I retired 5 years ago. Could past numbers indicate a current problem? I appreciate you reminding me of as it’s been quite some time since that level was checked.

    Is cortisol all I should have checked? And can a patient take adrenal supplements while also taking an NDT? I know they sell adrenal supplements at Whole Foods. I would like to add those to my drug regimen if that would help me in any way. If yes, is there a particular brand(s) you can recommend?

    Thank you in advance for all of your good information and answers, Dr.Cheryl. If I lived near AZ I would come and see you. However, I am on the east coast. I sincerely appreciate any info that you’re willing to share with me and your readers. Sorry for so many questions but you sound wonderful!



  11. Doing some research for a resident. Saving your webpage among others for future reference. These might provide some help.

    Found some discussions on the different experiences and formularies. Because their are different fillers being used by the pharmaceutical companies, my own thought is that the efficacy and reactions are indeed due to the fillers and the respective individual’s reactions to them.


    Your own reference is good, too, but the one above goes into more detail. The chickory base for inulin, though, is also important to know and be aware of.
    A suggestion regarding stomach upset is to try taking it sublingually rather than swallowing. NP Thyroid can be taken that way; Armour has to be crushed as the formulary now includes cellulose, which is hard to break down on its own. One of the participants on the following blog uses a bit of sugar, but for those with diabetes, you can substitute stevia or xylitol to help with the taste. More discussion here:
    Thanks for the website and the useful discussions above. It all helps.

  12. I have been on Armour thyroid for probably 15 years. Although it took time and a few blood draws, the effort was worth it as I have had no problems. However, last year I switched to Naturthroid on the advice of my doctor and find the drug harsh. And this past month, with a new script have been so sick with debilitating stomach cramps (think labor pains) and didn’t no why. I finally made the connection and now feel fine having stopped taking that particular refill. Fortunately, I had other refills that I could take w/o problems.
    Which brings me to your point of fillers. I am proof that they make a difference and your article help be make the connection. I will switch to WP Thyroid and see how that works.
    Thank you Dr. Cheryl. Wish you worked out of CO.

  13. My wife has been using armour Thyroid. It now costs over $100. for 60 mg 180 pills.
    We have heard other sources suggest WP Thyroid.
    How can she get this product. Need a DR. prescription?

    • Hi David,
      WP Thyroid is a prescription medication. You need a doctor’s prescription for it. Some pharmacies can get it, however more commonly they will stock Nature-throid. Some doctor’s offices also dispense WP Thyroid to their patients.

  14. Re: Losing weight under low thyroid.
    I’ve being taking Armour Thyroid and despite my diet change of organic/healthy and exercising I don’t lose an once no matter what! Would WP-Thyroid help me with this issue? I’ve heard that the issue of not being able to lose weight is the lepid resistance on thyroid patients. I want to try WP-Thyroid since the Armour Thyroid (from 60 to 90 Mg increase still makes me sleepy having to take naps all the time and my overweight). Please advise. Thank you.

    • Hi Lourdes,
      The big mistake people make is thinking taking thyroid medication will fix everything. Yes, you have changed your diet and are exercising, but there are other causes evident in your question. If you are still sleepy, you must look at adrenal and female hormones to start. And how you are eating – cycling carbs as in the Adrenal Reset diet may help. That said, the WP Thyroid has the advantage of easy to absorb and hypoallergenic fillers, so it may help to switch, but don’t bank on that solving everything.

    • Lourdes I have definately found to have lost weight on wp throid. It has given me more energy to work out after work. I do also watch what I eat. But it has helped.
      Just my 2 cents.

  15. I have Nature-throid and WP Thyroid. I have noticed that the WP thyroid has a smell like animal fat(grease) the Nature-throid doesn’t . why is this?

    • Hi T Robin
      Both preparations are composed of natural dessicated thyroid plus a filler. The NDT is an animal glanular product so it can smell like animal fat. A sensitive nose like a dog’s would recognize the NDT in the Nature-throid. (Keep them away from pets!) You may not because it is tightly bound in its filler. The fillers in the WP thyroid are softer and allow the tablet to dissolve more quickly. Therefore the NDT is easier to smell in the WP Thyroid.

  17. I HOPE SOMEBODY WILL HELP ME to buy that NATURAL T4, T3, T2, and T1 ❗️
    I am not very good with internet yet. I found the information about natural medication for the thyroid, but I CANNOT find where to buy it!
    PLEASE HELP ❗️❗️❗️

    • Hi Diana
      The natural dessicated thyroid medication that I wrote about in this blog is a prescription medication and must be prescribed by a doctor. You cannot order it yourself on the internet. You must go to a doctor who prescribes natural dessicated thyroid medications, because a lot of them do not, only synthroid.
      In health,
      Dr. Cheryl

  18. Is it true that NDT can be taken once daily, instead of several times daily which many NDs recommend? I personally find multi dosing to be a hassle, but want to make sure I optimize the uptake of T3 in NDT…any advice would be greatly appreciated.

  19. As a pharmacist I want to commend you on a very well written article. For those of us who are well-studied on thyroid illness, you confirmed all that we have come to know and for those just beginning their journey, it’s a great start. Your attitude is just as impressive in that you personally are concerned about the patient, rather than on avoiding the complexities and ego-crushing effects of treating someone suffering from hypothyroidism. If I lived near Cottonwood I would certainly request your services as a patient.

  20. Is WP Thyroid generic for Nature-throid? My regular pharmacy has trouble many times getting the WP Thyroid so I am wondering if Nature-throid would be easier for them to obtain? Thank you.

    • Hi Pam
      I have heard pharmacists call Nature-throid a generic for Armour thyroid, so who knows what anyone means by generic. In fact, WP Thyroid and Nature-Throid and Westhroid are brand names manufactured by RLC Labs. Yes, sometimes one or another is harder to get, depending on demand and supply. The only difference is in the filler used. In a pinch, one could substitute for another, but usually patients do better on one and should stick to that.
      In health,

  21. My Integrative MD wants me to go on WP Thyroid PLUS Synthroid together. What are your thoughts on combining Thyroid medications? Thank you!

    • Hi Nia
      Sometimes combining WP Thyroid and a T4 medication like synthroid is the exact combination a patient needs. You would know that not only from blood tests but from how you feel.
      I have encountered practitioners who follow the belief that the proportion of T3 to T4 in WP Thyroid is too heavily weighted to the T3 and so want to add more T4 from another source. This also may be the case.
      How you feel and how that is interpreted should be the guideline. In addition, remember that thyroid medication is not the only tool you have to get to the bottom of your symptoms.
      In health,

  22. Hi DR. Cheryl,
    I am in a panic. All my local pharmacies plus my insurance pharmacy all say that Nature Throid is “on back order.” It’s been that
    way since July, 2017 when I tried to reorder. My local pharmacist said the company is no longer making it? Is “Back order” a eufamism for no longer available?
    I took Levothyroxine and Synthyroid for 44 years. Neither worked for me: my hair dropped out (I have no body hair,) I was always cold, my basel temp hardly ever rose above 96.3 and I had zero interest in sex. And these are only the worst three non corrected effects.
    I’ve been on Nature Throid for one year: my numbers are now “normal” and I feel well. Something I never achieved on the sythetics. Where can I continue to buy the medication I need? Help, please?

    • First of all, panic is not helpful nor warranted in this situation.

      RLC labs, who make Nature-throid and WP Thyroid, recently sent out an email that I received which states: “We at RLC Labs want to thank you for your patience as we completed some necessary infrastructure upgrades. These upgrades included moving to a larger facility, implementing new technology, and refining our processes. As many of you know by now, these upgrades unfortunately played a role in the backorder of Nature-Throid, WP Thyroid, and Westhroid.”

      The email, dated October 11, 2017, goes on to say: “Despite rumors, we ARE manufacturing and are NOT going out of business. We are working day and night to get back to our usual pace and expect to start shipping in the next two weeks.”

      My recommendation is to call around to different pharmacies to see if they have any stock left. In a pinch, I would also recommend temporarily switching to Armour thyroid since it is also made of natural dessicated thyroid and I have found that to be available.

      In health,
      Dr. Cheryl

  23. Hi, I have been on np thyroid for sometime and it is the best natural thyroid for me! Why is it virtually unavailable or on backorder? How can we found out what is going on??? I personally feel it is a conspiracy to get us to go on pharmas, NOT!

    • Again, this is a correspondence direct from RLC Labs, the manufacturer:
      We at RLC Labs want to thank you for your patience as we completed some necessary infrastructure upgrades. These upgrades included moving to a larger facility, implementing new technology, and refining our processes. As many of you know by now, these upgrades unfortunately played a role in the backorder of Nature-Throid, WP Thyroid, and Westhroid.
      We sincerely apologize for the strain this backorder has caused for our customers and patients and greatly value your continued support. Every effort is being made to get all strengths stocked as quickly as possible while still adhering to our strict quality standards – our medications are not released outside of +/-2% variance between T4 and T3, while the industry allows for a monograph discrepancy of +/-10%.
      This is not a conspiracy. Have patience. Some NT 1 grain is being shipped.
      In health,
      Dr. Cheryl
