Having lower TSH levels when taking thyroxine not unsafe, says recent research

(Though this post was first written in 2010, it still works for today and is very pertinent!)

I am amazed.

The Society for Endocrinology in the UK reported that taking higher doses of thyroxine (which will lower the TSH lab result) may be safer than has been purported for decades.

And how low a TSH lab result did they find to be safe? As low as 0.04-0.4, the research found. It’s still safe enough to not cause an increased risk of  “heart disease, abnormal heartbeat patterns and bone fractures”, aka HYPERthyroid symptoms.

And those of us worldwide who know about the superiority of having T3 in our treatment (like a working natural desiccated thyroid, T4 with T3, or even just T3-only), can also use these research results in our fight to be on enough with TSH-obsessed doctors. They tend to view research as the end-all to the truth rather than solid clinical presentation, sadly.

Because when we have enough T3 to feel fabulous again with all symptoms removed (in the presence of good cortisol levels, adequate iron levels, B12 and digestive issues), our TSH lab result is always low, aka suppressed, and without one iota of hyper symptoms.

Patients have experientially known this truth about the lousy TSH lab test, without research, for years!

P.S. You WILL feel good most of the time with a midrange free T3, but it eventually backfires. We have to get that free T3 optimal. <—Read the latter.

But here’s what’s missing from their research:

  1. Those “safe, low levels” of an ink spot on a piece of paper do not mean the 16,426 patients they followed will be without numerous issues related to being on a storage hormone alone.  i.e. the body is not meant to live for conversion alone! A healthy thyroid will convert T4 to the active T3, but it will also provide direct T3 in addition to the T2, T1 and calcitonin…none of which a T4-only med provides directly.
  2. Additionally, the TSH lab test only reveals the action of a pituitary messenger hormone called the Thyroid Stimulating Hormone (TSH).  The lab test does NOT measure whether your tissue is receiving enough thyroid hormone, which is why so many patients on T4 end up with depression, rising cholesterol, high blood pressure, low B12, low iron, and many symptoms, as well as adrenal fatigue thanks to the inadequate treatment of T4.
  3. Raising T4 often encourages an excess production of Reverse T3 over time, which will block cell receptors and increase the very symptoms the researcher state is avoided, as well as far more hypothyroid symptoms.

On the positive side

This is just one more research study that ends up being on our side!  i.e. it fits our experiences. I have also included mention of this study on the following page on STTM, where I keep a ongoing list of research which supports what patients already know by their experience and clinical presentation:  www.stopthethyroidmadness.com/medical-research/

Here’s the skinny about the “new” Naturethroid: the good, the bad, and the curious

(A lot has gone on since this post below was first put up in 2010. So after reading the below, see what happened in 2017 here.)

As the one grain tabs of Naturethroid desiccated thyroid by RLC Labs are hitting pharmacy shelves again all across the nation here and there after the recent shortages and the sad reformulation of Armour,  and patients are starting to use the new Naturethroid, we are gathering some good information, both anecdotal and factual:

  • The typical smell of desiccated porcine is less intense with the new tablets. We have no idea why.
  • The tablets are now stamped with RLC on one side, and N over 1 on the other, whereas before you’d see just NT1 or a reference to the fact that Time Caps Labs (TCL) used to make Naturethroid for RLC Labs
  • The package insert is no longer inside the bottle but stuck on top of the cap
  • Lot number info used to be on the edge of the label running vertically, whereas now, it runs along the bottom of the label  under the ingredients.

One grain is still 65 mg, with the T3 content being at 9 mcg and the T4 content being at 38 mcg.  The T2, T1 and calcitonin still unmeasured.

There are filler/inactive ingredients which have changed:

  • Calcium filler has moved up from 16 mg to 17 mg (calcium binds thyroid, but you just take more. Don’t swallow it with milk, please.)
  • The old contained Magnesium, Potassium, and Sodium (each at less than 1 mg), whereas in the new, potassium is now removed
  • And here’s the best part: the old NT had Hydropropyl Methylcellulose–that’s the larger size cellulose structure which we know binds some of the thyroid hormones. Now, the new NT has Microcrystaline Cellulose, the smaller size. (Too bad we can’t see all cellulose removed!)

Below are the new NT fillers, which are identical to the old except for the cellulose change:

Carnaba Wax, Colloidal Silicon Dioxide, Dicalcium Phosphate, Hypromellose, Lactose Monohydrate, Magnesium Stearate, Microcrystaline Cellulose, Polyethylene Glycol (PEG)-400, Sodium Starch Glycolate, Stearic Acid.

Most all the above comes courtesy of Stephanie Buist, owner of the Iodine group on Yahoo and thyroid and adrenal patient and advocate.  Thank you, Steph!  You can read about the fillers here by scrolling down.

Oh and by the way, the new tablets are now scored. A helpful addition!

In patient groups, we are seeing a variety of experiences with the new Naturethroid.  Most folks seem happy with it so far, and even some report it seems a tad stronger than the old (the cellulose change may have caused that). Occasionally, someone will report problems, but they appear to be from underdosing or a potential RT3 problem which has arisen and needs treatment with T3-only.  Changing brands can also bring different reactions, so you have to wiggle the dosage around sometimes to find your sweet spot once again.

All in all, it looks good.

If you missed the last internet radio Thyroid Patient Community Call with Dr. Kent Holtorf, you missed a VERY good one. Thank you Dr. Holtorf for excellent information. But good news! All the shows are recorded.  Just go to the following link, scroll down, and you can click on any past interviews, including two with Dr.  John C. Lowe and a great one with Endocrinologist Dr Pepper–one of a rare breed of open-minded Endos.  (I’ve also stopped doing my long intro’s about me in the last two, figuring if someone wants to know, they can go to the About Me page, or read the Introduction in the book which has even more detail. lol.)

Dr. Lowe wants to talk to you more directly this Thursday–post your questions here!

Dr.JohnCLowe

Please note: Dr. Lowe is NOT an MD or DO who see’s patients and can prescribe. He’s a thyroid and fibro “researcher” with good knowledge about T3,  fibro, metabolism, supplements etc. Many questions have been coming in which are already answered on STTM, or are more targeted to a practicing physician, not a researcher. FYI.
🙂
1-14-08: COMMENTS with your QUESTIONS ARE NOW CLOSED TO POSTING.  There are more than he can answer right now. See you tonite!

On the heels of an informative and wonderful THYROID PATIENT COMMUNITY CALL on Talkshoe last week with Dr. John C. Lowe (see posts below), we’re going to do it again this coming Thursday, January 14th.  Join us for Part 2!

Dr. Lowe is a fibromyalgia, thyroid, and metabolism researcher who has always been such a champion for better diagnosis and treatment in thyroid patients. He is Editor-in-Chief of the open access journal www.thyroidscience.com as well as his own www.drlowe.com

And this time, Dr. Lowe is going to spend more time answering  your specific questions. Check out his websites above to get an idea what his expertise is, which includes the use of T3,  Hashimotos autoimmune thyroid disease, iodine, fibromyalgia, the tyranny of the TSH lab test, good supplements, the FDA, and more.

So here’s your chance: think of one or two questions you’d like to hear him answer. Please, if you have more more than two,  narrow them down to the two most important, and keep them brief.  No exceptions. Two max only, and brief.  Then use the Comments below to post them.  Be sure and check out if your questions have already been asked in other comments.

I’ll be collecting the questions ahead of time and will let him preview them. He wants to give you his best.

TIPS ABOUT TALKSHOE: Some reported being booted off and having to quickly rejoin. One step that may help is to download the Talk Shoe Live Pro ahead of time (takes 25 minutes for some) and use that software during the call, since it gives you far more stability.  Also, make SURE you have everything else closed and/or not running on your computer at the same time you are in the Talkshoe call. I will also be chatting with Talkshoe support and will get more ideas.

Also, don’t wait until the call occurs to mention your question. We found it difficult to try collecting them on the Chat. Ask now!!

Yes, you can also call in live during the Call, but it’s good to first let me know your question here.

And finally, at a certain point of those who join (after 300 on chat), Talkshoe participants are automatically unable to post on the chat. You can listen, but no chatting. So if you want to chat, join as soon as the Call opens up, which is 15 minutes before the actual audio begins. Times for the audio are 9 pm Eastern, 8 pm Central, 7 Mountain, and 6 pm Pacific.

Reverse T3–do you have this problem in excess? Let’s talk!

Screen Shot 2015-12-04 at 5.53.48 PM

This blog post has been updated to the current day and time. Enjoy!

Most thyroid patients have heard about T4…the thyroid storage hormone, also called a pro-hormone. You’ll see it in literature as “thyroxine” or “l-thyroxine”–the latter as the name for a man-made T4.

And many know about T3…the active thyroid hormone which rids us of hypothyroid symptoms.

And as patients become more informed, they learn that the body not only converts T4 to T3 through what is called deodination, it also provides some of that T3 directly. That is an important distinction! The latter fact can be why thyroid patients report getting far better results with natural desiccated thyroid (NDT) like Naturethroid, NP Thyroid or other brands.

Patients might also learn that there are actually five thyroid hormones made in your body, which is also what’s found in NDT: T4, T3, T2, T1 and calcitonin.

Reverse T3

But in every individual, whether a thyroid patient or not, a thyroid can also convert T4 to the inactive RT3 (reverse T3).  RT3 is an inactive thyroid hormone, as compared to T3 as the active thyroid hormone. And converting to RT3 is a natural and necessary process, even if there are consequences.(1)  The body might convert T4 to RT3 as a way to clear out excess T4, or as a way to reduce your metabolic rate.  It can happen if you go through any of the following:

  • surgery
  • a major physical accident
  • certain heart problems
  • intense chronic stress
  • restrictive low carbohydrate diets (2)
  • chronic inflammation

When Reverse T3 is a problem

Unfortunately, many thyroid patients make far too much RT3, as well, and patients with their open-minded doctors have been making cutting edge discoveries about this fact.  Many patients have seen that their high levels of RT3 can be found with the following conditions:

  • high cortisol
  • low cortisol
  • low iron levels
  • possibly low B12
  • lyme disease
  • gluten intolerance or Celiac
  • other undiscovered and untreated underlying issues that can go hand-in-hand with being hypothyroid.

Why is a high level of RT3 is problem? That excess RT3 is making itself lazily comfortable on your thyroid cell receptor sites, preventing the active T3 thyroid hormone from doing its job on that same receptor to get you out of your hypothyroid state.  It becomes akin to a clogged up drain to your organs and cells. So you stay hypo and symptomatic, in spite of seemingly “normal” other labwork.

The solution

Informed patients discovered they needed to discover and treat all the reasons contributing to their body converting to excess RT3.

Want to read more? All the below is based on patient experiences and wisdom to share and work with your doctor:

For those with the revised Stop the Thyroid Madness book, there is also more good detail in Chapter 12 called T3 is the Star of the Show, page 155, to continue your education. This is all good information to take into your doctor’s office.

Is Cellulose the real problem in desiccated thyroid meds for many?

Screen Shot 2015-08-05 at 12.53.55 PM(This blog post is updated to the current day and time. Enjoy!)

When Forest Labs reformulated Armour desiccated thyroid in early 2009, they stated they increased the filler Microcrystalline Cellulose, and decreased the Sucrose (sugar). And all of sudden, the tablets became impossible to do sublingually–a method so many of us loved and which seemed to give even more of a punch.

And we were left wondering in 2009 why they would change a particular quality (being able to do the tablets sublingually) that thyroid patients praised so heavily?  Positive opinion among patients for Forest Labs back then slipped several notches. (Forest Labs was bought out by Actavis in 2014)

But the real cuckoo’s nest for many thyroid patients still on Armour in 2009, who knew firsthand the life-changing benefits of natural desiccated thyroid, was a maddening return of serious hypo symptoms on the 2009 Armour with its increase in cellulose, and subsequent new stress on their adrenals, sooner…or later! You can read several horror stories in the comments of the post below, or go here.

So patients turned to other alternatives, which at the time was Naturethroid and Westhroid by RLC Labs. (Naturethroid stopped working as well in 2018)

So what has been the common thread in the most problematic desiccated thyroid products?

It has always been CELLULOSE, a plant fiber, and more commonly known by the trade name Avicel. And what does fiber do in your stomach? Inhibits absorption. Armour’s cellulose was raised, and bamm…problems.  Compounded desiccated thyroid, with cellulose as a filler, has been problematic for many patients with a return of hypo symptoms, especially if it was Methyl Cellulose, a larger particle size product. But some have even had problems with compounded containing Microcrystalline Cellulose, the smaller cellular product. And a certain body of patients even had problems with Naturethroid back then before it became scarce for awhile. And Naturethroid used cellulose as a filler.

Note: With all the complaints, Forest Labs did change something about Armour by mid–to-late 2010. Though it never returned to what it was before 2009, it did become a softer tablet and patients did better on it. But we certainly learned a big lesson about cellulose in our NDT pills..

Is this problem true with T3-only products?

Yes. Patients noted that generic T3 was far less effective than the brand name Cytomel (both Liothyronine Sodium)  And what filler is up to 70% in the generic T3?  CELLULOSE.  

What does literature say about the use of Cellulose as a filler in medications?

Plenty. Cellulose is from wood. Wood is fiber. And fiber in your gut affects absorption. From http://www.umm.edu/altmed/articles/fiber-000303.htm we get this:

* Dietary fiber has been reported to lower the blood levels and effectiveness of tricyclic antidepressant medications…Reduced dietary fiber intake increased the blood levels and improved symptoms in these patients.

* While fiber supplements may help to regulate blood sugar levels, they may also interfere with the absorption of anti-diabetic medications….Therefore, fiber supplements should not be taken at the same time as these medications.

* Taking soluble fiber such as psyllium with carbamazepine (Tegretol), a medication used to treat seizure disorders, may decrease the absorption and effectiveness of carbamazepine.

* Fiber in the form of pectin (from fruit) and oat bran reportedly reduces the body’s ability to absorb cholesterol-lowering medications known as “statins,”… and could lead to decreased effectiveness of these medications.

* Fiber supplements may reduce the body’s ability to absorb digoxin (Lanoxin), a medication used to regulate heart function.

* Clinical reports suggest that psyllium or other soluble fibers may lower lithium levels in the blood, reducing the effectiveness of this medication.

* In one clinical study, the fiber supplement guar gum reduced blood levels of penicillin.

Fast forward to the present

If you are using a compounded desiccated thyroid medication, it’s strongly recommended to request powdered acidophiles, also spelled acidophilus, as your filler.  One gal states her compounding pharmacy uses powdered Ginger (but beware of too much Ginger if you have Mitral Valve Prolapse. It can cause palps if you take too much–my experience).  Others might use powdered Vitamin C.  See what other fillers your compounder can offer.

Another possibility is Cellulase, an enzyme which helps the splitting and breakdown of cellulose, It’s found on most supplement websites.
