Are you switching to Nature-throid? Here’s 10 good things to know!

Screen Shot 2015-09-27 at 1.33.08 PM(This page has been updated to the current day and time. Enjoy!)

In 2009, there were many folks reporting problems with the newly-formulated Armour (and that has been true for 2015, sadly), just as there was a growing body of individuals stating they are switching to Naturethroid by RLC Labs (formerly Western Research), another prescription brand of desiccated thyroid which also makes WP Thyroid.  

Today, there are even more quality brands to consider. And when a brand like Armour disappoints, many are also switching to NP Thyroid by Acella.

But if you are considering Naturethroid, here is info to carry with you if you switch:

  1. Naturethroid has a coating on the outside, and some patients state they bite on the pill to remove the coating, and still try to do it sublingually. No sugar, but some are determined.
  2. One grain of Naturethroid is 65 mg rather than the 60 mg that Armour users have been used to. Two grains are 130 mgs, etc. (One grain is actually 64.8 but it’s easier to round it up). Strengths are 1/4, 1/2, one grain, two grains, three grains.
  3. The makers of Naturethroid started making 1 1/2 grain tablets by 2010.
  4. Ingredients are
    • Porcine Thyroid Powder, U.S. Pharmacopeia
    • Microcrystalline Cellulose
    • Dicalcium Phosphate
    • Sodium Starch Glycolate
    • Magnesium Stearate
    • Hydroxypropyl Methylcellulose
    • Stearic Acid
    • Carnauba Wax
    • Polyethylene Glycol
  5. Naturethroid uses the same USP thyroid powder as any good desiccated thyroid product—it “adheres to full pharmaceutical purity and standardization on the consistency of the hormones along with full pre-and-post testing procedures associated with quality prescription products.”
  6. RLC Labs is a small and friendly pharmaceutical company.
  7. Twitter has a Nature Throid website.
  8. RLC labs also used to distribute Westhroid more than it does today (simlar), but that has largely been replaced by WP Thyroid–an NDT with very few fillers.
  9. When switching, you will have to figure out if you need to be on a similar amount as before, or a different amount, according to symptoms.
  10. And finally, it’s been around since the 1930’s–another tried and true desiccated thyroid product!

    I’ve been self dosing for years on westhroid because doc had no clue, now on 4gr, finally found a doc who has extended thyroid knowledge. He switched me to nature-throid, stating that others had better results on this compared to being on westhroid. I just picked up my Rx and it looks like the same pill that I was taking, only it’s 1 1/2 grain and my new dose is 1 pill every day. Is there any difference between the two? I read that they are identical. It’s making me question this docs knowledge, but he still doses by symptoms and not TSH, so that makes me hopeful. I’m worried because every time I tried to reduce my dose because of TSH, once I reach 3.5 gr, I get pain in my shoulder and back, 3 gr and I feel like an old person with joint pain and I actually start limping. Do you know of anyone switching between the two for better results? Thank you so much for all the valuable information you provide all of us. You are truely a blessing from God!

      I have not seen better results with Naturethroid Vs Westhroid. They are, in fact, almost virtually identical and the makers admit that.

    My endocrist’s PA has agreed, at my request, to switch me from 112mcg Synthroid to Naturethroid. She said to just start on 90mg, saying it was roughly equivalent to the 112mcg Synthroid dosage. I asked if I should “wean” myself off the Synthroid, and she said no, just to start the Naturethroid. When I asked if I should multi-dose to prevent stressing on my adrenals, she didn’t think it was necessary. I suggested (after reading STTM) that I would feel more comfortable starting with 1/2 grain (32.5 mg) of Naturthroid in the morning and 1/2 in the afternoon for a 2-week period, then increasing to another 1/2 grain after 2 weeks, for a total of 90mg, if I tolerated it well. She said I could do whatever I want! Can you advise as to the best way to transition? Also, 3 years ago another doctor put me on 112mcg Levothyroxine with 5mg of Cytomel added twice a day. I experienced significant hair loss for 3 months and asked to discontinue, also because I didn’t feel any better. Who needs to feel lousy and go bald at the same time! At this point, I have more faith in the research and facts you have presented in STTM than I do in the medical professionals I have seen thus far. Thank you for any help you can provide!

      Congratulations on the switch! Yes, most of us just take T4 one last day, then start on NDT alone the next and never look at T4-only again. NDT is 80% T4 anyway! By the way, there’s a very strong possibility that 90 mg (1 1/2 grains) won’t be enough and you’ll need to raise in search of your individual optimal dose. Mine, for example, is 3 1/2 grains, but everyone is different as to what is optimal. All explained here: http://www.stopthethyroidmadness.com/natural-thyroid-101

    Hi Janie. I made the switch from 112mg Synthroid to 60 mg Naturethroid 3 weeks ago. One week later, I increased my dosage to 90mg, and was planning to increase again to 120mg today (one week later). I had been feeling markedly better, BUT a couple of days ago, noticed the headache and foggy brain symptoms of hypo came back somewhat, and my hypo weight gain (only 5-6 pounds) is still there, despite being gluten free for a month, and eating basically “clean.” Yesterday morning, I decided to whip myself back into shape with an 8:30 zumba class. I had taken my morning 60mg Naturethroid at 6:30, so I knew I’d probably feel the T3 “peak” at some point during class. Wow!!! Half-way through, I felt my heart rate was really elevated moreso than usual, and I felt hyper-like symtoms of neck and shoulder tension. OK, maybe not a good idea to jump back into zumba, since I hadn’t done it or any other heavy-duty cardio in probably a year. This morning, my hip and knee joints are really feeling it, so I decided to just do some lightweight resistance bands for bicep/tricep strength. Same thing all over again. That was 5 hours after taking my morning 60mg, and I’m still feeling hyper shaky. Like I said, I was planning on increasing my dosage from 90mg total to 120mg today, but I’m not so sure what’s going on here. Can you enlighten me please?

    Janie, I do have an Rx for Nature Throid at my pharmacy right now. I have a different ? though. I have a 4-point Cortisol Saliva test from Quest Diagnostics and have heard that that test from them isn’t good. Why? What’s wrong with that lab? I’m supposed to be doing the test this wednesday. I hope to hear from you before then. Thank-you

    The dr increased my levothyroxin from 50mcg to 75mcg back in Dec. I am asking him to put me on Naturethroid. I feel fatigued, really tired, muscle and joint pain in my legs and arms, depressed with no energy. I have been on Synthroid 50mcg for two years until Dec 2015 then switch to generic brand levothyroxin. Not helping. I also was recently diagnosed with high risk for fractures with osteoporosis in my spine -3.5 with some disk degeneration L4-5 and I was deficient in vit D and B12. The labs for those are fine now. Q:what dose should my dr start me on for the Naturethroid? Does anything else stand out to you concerning my condition? I just turned 62. Thank you very much.

    I am on Armour, 3 grains, and am optimal. I feel really good! I do have a little itching with it. I want to switch to another ndt, because my last refill went up in price again. I am gluten and lactose intolerant. I have read the information on what is in Naturethroid, but it says it is a traceable amount as part of desiccated thyroid powder, which makes me think all ndt’s contain it? Are you aware of anyone else who is lactose intolerant who reacts to this ingredient? I did read that it is gluten free. I am feeling so good, I don’t want to switch and start having belly problems. Is there a particular ndt that you would recommend for someone like me? Thanks!

      If you can get naturethroid, go to CVS and ask them about card to cover cost, I pay $24 for my morning dose 113.75 and $20 for my afternoon dose 97.5

    Can you please expound onthjs a bit more so I understand better. I feel perhaps I am at this point. Thank you. But patients who want to start lower learned to keep going up, bit by bit, to counter the feedback loop suppression. i.e. those lower doses have made some patients feel even worse if they stay on them too long.

      There is a system in your body called the hypothalamic-pituitary axis…or the feedback loop. It’s a messaging system from the hypothalamus (tiny gland in your brain area), to the pituitary (another tiny gland in your brain area), to the thyroid…and back again. It’s all why your thyroid releases thyroid hormones in the first place. It’s “told to do so” by this feedback loop.

      When we start on thyroid meds, the little gland in the brain called the hypothalamus senses it, though it doesn’t realize it’s coming from YOU giving it to yourself. Instead, the hypothalamus thinks it’s your own thyroid doing it! So, the hypothalamus stops telling the pituitary to stop messaging your thyroid to produce! So now, your own body makes even LESS thyroid hormone release on top of a very low starting dose of thyroid meds…and we can feel worse. Thus the importance of raising of thyroid meds pretty systematically and not too slowly.

    This is such a wonderful website– thank you for providing all the information and for answering questions. I am going to order the book! I have a question about switching from Armour to Nature Throid. I was diagnosed with Hashi’s in 2010 with a TSH of 4.61 and TPO antibodies of 187. I have been on Armour since then. Started at 30 mg, then 60, and have been on 75 mg for the past 2 years. My T4 and T3 have stayed on the low end of “normal” range over the past 6 years but my TSH bounces around — each time the Armour was increased it dropped below 1.0 but then would “rebound” back up to high 2’s. At my last blood test in March it was 3.85 and my doctor agreed to switch to Nature-Throid and raise it to 113 to see if that will help my symptoms — weight gain, fatigue, increased LDL out of the blue, etc. Plus my TPO antibodies have been over 2500 for past 3 years.
    Is it OK to increase the dose from by a 1/2 grain, or should I ask for a 1/4 grain increase right now. Many thanks-

    After 25vyears on Synthroid and never feeling great, I found a doctor that switched me to Naturethroid 4 weeks ago. I was on
    .125 Synthroid and he started me on 3/4 Grain (48.75) two tomes a day. After 3 weeks I was still fatigued, so he doubled my dose. The first two days I was ok, but the third day I ended up in the ER with severe palpitations and HBP. I don’t want to give up on the Naturethroid, I think he was just too aggressive with the increase? What is the average dose increase for Naturethroid?

    Does anyone “break out” from naturethroid? I’m on 130 MG and I break out on my face, neck and arms “I guess adult acne”. I never had acne very bad until now and I’m 46
