armour thyroid conversion

you can google it conversion armour thyroid or look online there is a thread with some conversion charts on it.

1 grain armour (60mgs) = 100mcg levo, 1 1/2 grain armour (90mgs) = 150mcg levo, 2 grains armour (120mgs) = 200 mcg levo. These are approx, but you will probably end up on more armour than the conversion shows. Now.......you shouldn't start out too high of dosage either. That T3 will hit your system hard if you take too much to start. Usual start dosage is 60mgs. At top right hand area of this page you will find where it says health pages, go there, then find the armour information.

pdf If you look at the table you will note that 100 mcg of synthetic T4 is supposed to be the equivalent of one grain (60 mg) of Armour Thyroid. Then you look further and it shows 100 mcg of T4 to be equivalent to 25 mcg of T3. This means that each mcg of T3 is equal to 4 mcg of T4. Since Armour Thyroid contains 39 mcg of T4 and 9 mcg of T3, if you convert the T3 to equivalent T4 (multiply by 4), then 39 plus (9 times 4) equals only 75, not the 100 shown in the table.

The conversion of T4 to an NDT med like Armour or Nature-Throid depends on an assumption of the activity of T3 to T4. Assumptions are that T3 is somewhere between 4 to 8 times as active as T4. Therefore, the conversion factors usually are one grain of NDT med is equivalent to somewhere between 75 and 100 mcg of T4. So your doctor gave you too much Armour. One grain would have been closer to your T4 dose.

100mcg of levothyroxine is about 60mg of armour -- you need to work with a doctor to make sure the conversion works out for you and that labs are appropriate.

I meant to add the conversion to 1 grain of Armour (60 mg) is 50 mcg. I've read different conversion dosages online but my endo prescribed 1 grain (60mg) a day for 50mcg of eutroxsig (generic version of Oroxine). I wasn't absorbing Armour so I switched back to Eutroxsig.

html When you see your doctor next you need to get him to understand about the correct conversion of the T4 dose to Armour. You need to be on at least 2 grains of Armour, based on my calculations. Also, you need to find out if the doctor is going to be willing to treat clinically as described. If not, then you will need to find a good thyroid doctor that will do so.

Hi everyone. Doctor has switched me to armour thyroid as of yesterday. I have been on 50mg of synthroid. I am now on 30 grains of armour. Now I was cruious if any of you watied a couple of days before you popped the pill, or if you just up and switched? Is the conversion higher than what I am currently taking?? What side effects if any?? Thanks!

I had read so much about getting on armour thyroid that I was glad when the new doc ordered armour. Now I have been reading about the new formulation and am wondering if I would do better with getting my levels up if I switched to the ERFA? Will my levels ever get where they need to be if I stay on the Armour? there is so much to consider here. It sounds like you can easily have your RX changed to a different pharmacy that would provide the ERFA. Has anyone done this?

You know the more I see people with TT's having problems with the T4/T3 conversion the more I am convinced I am seeing a pattern here. I see that too many of us are being treated as if we still have our thyroids. The thyroid normally converts the T4 into T3, but if we don't have that physical action, then no wonder we don't cope! I still believe that the medical profession is about 60 years behind the research...and unfortunately we have to suffer! My T4 is always super high...

I have Hosimoto's and I've taken Armour Thyroid since 2000 and will never take anything else. Armour Thyroid is all natural - not synthetic. The doctor who first put me on it only prescribed Armour. He didn't like the long term affects that could be caused by taking synthetics. I had surgery in 2002 and 2/3'ds of my thyroid removed. The surgeon wanted to take me off Armour and put me on Synthroid but I wouldn't let him.

In fact, when people take Armour their RT3 will usually be lower and their FT3 much higher most of the day. So I just give such patients Armour thyroid until/unless Armour does not seem to be effective at strong doses and they seem to still overconvert T4 to RT3. Again, one has to then reconsider whether their body may be right and they cannot tolerate strong thyroid effects for some other reason.

I was wondering if anyone has a link to a conversion table for the Erfa Thyroid. I was on 75mcg of Synthroid and my gp started me on 30mg of Thyroid. I tried to tell him that it didn't match my T4 dosage but he wants to wait for the blood work,arrgh. I was feeling great on the 30mg for about a week-what a tease,lol. Now I'm back to where I was before.

It is a synthetic conversion with your thyroid medication and your body may be pushing hard to convert the T4 into the T3 Have your considered trying Armour as a natural hormone replacement for thyroid? You may benefit greatly from the T1 T2 T3 and T4 already built in.

This is getting pretty technical, but I found this in Thyroid Manager: "That most plasma T3 is derived from peripheral conversion of T4 is supported by the fact that normal plasma T3 levels are obtained in athyreotic patients treated with sufficient T4 to achieve high normal plasma T4 levels.

I am not sure armour can help with anything but the thyroid. Why did they put you on armour after being on synthroid for so long? I had real problems with the armour and went very hyper on it. I went back to the synthroid. I am still trying to adjust the dose after being on it for four months. I hope they started you off on a small dose of the armour.

Yes, you can take Armour sublingually. Your testing has been very inadequate. Total T3 is considered an obsolete test, pretty much a waste of money. Your FT4 (the only one you've had) on 3/16 was excellent, just a little over midrange. Your doctor should be testing FT3, FT4 and TSH every time you have blood drawn. Your latest FT3 on 8/29 was just about at midrange.

At about 3 months with no meds, I went to endo and he listened to my story and then started me on new med (for me) of 15 of Armour Thyroid (the idea being to start very low to see how I would react). First night was like a miracle; slept better and all night than I had in years. (My husband got up out of bed and came over to my side to make sure I was still alive - that's how quiet I was.) Also, no more weird urine odor.

I was treated for Graves disease 12 years ago. I am on armor thyroid and synthroid. My blood is checked 3 times a year and the thyroid values are normal. I have fibromyalgia and many symptoms of hypothyroidism. Could I have a problem converting T4 to T3?

That may be why you are having such a hard time stabalizing....if that is the case, you will deal with the same thing with Armour. I am on Armour and it takes quite a period of time to adjust and to find proper dosage. It is not a quick fix and you must have patience as is the same for all thyroid meds. Unfortunately the thyroid is a slow fix period for most of us it seems! :) :) Welcome and look forward to hearing more!

I also read and was told recently by my endo with T3 meds it sometimes can suppress normal thyroid function. The thyroid - in a way gets lazy- when T3 meds are taken and then decides to sit back and let the med work instead of itself. That is scarey to me when a person still has their thyroid and it may just be in a non functional level - but could bounce back - if not in autoimmune distruction. T4 meds require a conversion - so that is why sometimes T4 meds are only given too.

I have tried synthroid years ago and it didn't help at all, infact I was more tired, so I took myself off and haven't been on meds for years. I just started with a new GP and we spoke about armour thyroid meds, I have started, it has been about 1 1/2 weeks. Don't really feel a change yet. Wondering how other people feel about the armour and your experiences.
