NT Thyroid vs Armour

Stick with whats making you feel well and disregard numbers.

suzy, my t4 was low on naturethroid but a few girls here and I think greygoose was one , explained that t4 will be low on naturethroid, and since ndt has all 4 hormones maybe you are overdosing especially where the t3 is concerned, hang on cos others will see the post and help you who are more informed than me , I am not well and cant think straight right now.

Hello if its makes you feel any better, I have had a very similar problem recently. I was on Na Thyroxine 125 ug daily ( stabilised for 20 years) and started to get the exact same symptoms as you. After eliminating heart, lungs, cardiac arrest, stroke on the way etc I stopped medication for 4 days and felt better. My GP said that I cant stop and had to just reduce my dose. So I then gradually re-introduced it starting at 50ug. Now I'm backup to 75-100ug and the light headedness and giddy spells plus elavated BP have returned. I bought a BP monitor so I could check at different times of the day and noted that although the BP is slightly elevated at around 132/ 84 my heart rate is low at 47 beats per min. Now I dont know whether to go up or down My T4 and is Ok and TSH < 0.05 so theoretically I should be OK, But I know that I dont feel "normal" ............grrr this is so frustrating

I am wondering if it is one of the fillers in Armour that is making you feel like this? The same happened to me, and once I was taking Nature Throid everything settled down again. Just a thought.

I get palpitations when I'm hypo, just to confuse matters!

I found quite a difference when I changed to NT from armour , I think the fillers are better, well , for me they were.

Unfortunatley doctors have no idea If we take thyroid hormones containing T3, the T4 will be low. That's a fact. As NDT contains all of the hormones we need we don't need 'extra' to try to rais the T4.

If she's using the normal blood tests for levothyroxine they cannot 'fit' with NDT

Is your doctor testing your FT3, or just your TSH and FT4. TSH and FT4 will not give you any useful information when you are taking any form of T3, because they are going to be low. It doesn't matter. The important number to test is the FT3, and you should be dosing by that, not the others.

That said, gordies could very well be right, and it is the fillers in Armour that don't agree with you. Could you not go back to the NT thyroid, and just take 1 1/2 tablets, and see how you feel on that, rather than switching brands. That would tell you whether it was the dose that was too high, or the fillers in Armour that didn't agree with you.

Sounds like you need Thyroxine instead of the INCREASE in NT or Armour. There is not much difference in NT and A, so it is as bluepettals2 says, you are overdosing on other hormones. I find that - generally - that people are better off on a split dosage; say 1 grain Armour/NT (which is similar in strength to 100 mcg Thyroxine) and 100 mcg Thyroxine. On retesting, you will find that T4 and T3 end up about the same level within the range. Say, T4 is half way up the range, T3 will be about the same. If your comfortable (normal pulse, no jumping heart, good energy) level is 1 1/2 grain, you may feel well on 3/4 grain Armour/NT and 75 mcg Thyrosine.

i dont know if this helps but my dr told me that if your adrenals are off or if your ferritin is low it can give weird signs/symptoms with ndt. But that being said , i think there is a huge difference in ndt meds. I was fine on thiroyd but since it is not prescripton dr changed me to nature throid same dosage and yet it feels different and i am having some muscle aches, and t3 rushes just a tad......

and plantar fascitus has come back in one foot which is so weird.......I did read on here that one lady had a similar experience and tired NP thyroid and it was what made her feel better hence less fillers and I think i am going to try that if dr will change me.

I get these symptoms when my t4 levels increase (I am on Armour &they are generally low) & also if my t3 levels are too high. Have been told I probably don't convert t4 well. My endo (sadly now retired) was never too concerned with my t4 levels being low as long as t3 ok. Best to find out what level you feel well at & see what your results are then so you can argue your case. Hope you feel better soon.

I take 30 mg of armour thyroid and doubled mine to 60 mg and noticed my heart started to flutter. I stopped and went back to 30 mg.

Having been stable on 125mcg of Levo for over 20 years my needs changed. Over time I came to be 2 grains of NDT (Nathure-throid), was well for some time and slowly, over months, found that the palpitations and the dizziness and so on were all returning. To cut a very long and involved story short, the ratio of T4 to T3 in NDT is much higher than we produce naturally. Some people suit this and some need to lower the ratio.

I went from 2 grains and SLOWLY dropped the NDT down to 1 grain whilst introducing Levo and raising it to 75mcg of Levo and 1 grain of NDT. This was good for a while but again the palpitations returned along with the raised BP and everything that goes with being a bit over-treated.

I'm now on 100mcg of Levo (Wockhardt - fewer excipients) and half a grain of NDT. Feel better on that.

You might be having too much T3 in the NDT for your needs a the moment. NDT is excellent, i have used it alone and in combo. It is not a one size fits all.
