T4/T3 Conversion problems & T3 resistance........

I've done research on both of these - as I've got a T4/T3 conversion problem at cellular level, caused by micronutrient imbalances & estrogen dominance. The information I've read is pretty in depth & complicated. I still can't quite get my head around T3 resistance, the more I research - the more confused I get!  Is having a conversion problem & being T3 resistant the same thing?

Forgive me if I am wrong but hasnt Armour got T3 in it and isnt it safer to take Cytomel if you have heart issues as with Armour, the dosage of T3 cannot be precise whereas with Cytomel (T3) it can be dosed accordingly.

Sorry for asking but here in Australia, Armour is banned because of the inconsistancy of just how much T3 is in it.

I am not saying it is wrong to take it but I would be very careful if you have heart issues.

Sorry for confusion, that was my blood work on last day of Synthroid (T4) only, so I was just wondering if by those lab results could I tell if I was right about needing T3. I was fasting.  I have not been tested yet on Armour and will ask to test after 4 weeks. I am on 120mg of Armour (which I am splitting 60 in AM and 60 in afternoon).

Unfortunately I didn't find this board until after the switch, (which was just 2 weeks ago), since I didn't start slowly as many of the posts suggest, I am concerned that I am going to have more problems.  I don't feel well and want to make sure I do everything i can or should to help the process. I wondered if I jumped to fast to Armour (very ironic that I would say that after a decade of being miserable on it and seeking alternatives).  I guess I am just paranoid or brainwashed after so many endo's refused to let me try t3 in any form. Since cytomel caused me strong cardiac symptoms (heart jumping), I thought  switching to Armour was next and only option.  Which I still am hopeful and I keep telling myself its only been 2 weeks+.
  
When I read about conversion and its mention many things can cause this, it makes me wonder if I something else has been overlooked. But I have no idea what those things are, I read adrenals, but since I have already made the switch should I still get checked? I take supplements especially Calcium, Vit D & Calcitriol since Parathyroid doesn't work. By the way, with splitting dosage of Armour, very hard to figure out when to take calcium 2 or 3 times a day!  Also take b-complex and Omega.

I am sorry I feel like I am babbling, I just want to do all I can and I am so appreciative of any and all comments! Thanks so much to everyone.

What is your dosage of Armour ? You said you have been on that now for two weeks?

If your doctor prescribe Armour correctly with the switched from Synthroid - your T4 would be still in the upper ranges due to the Synthroid T4 possibly still in the system.

It takes at least 4 weeks to rid Synthroid out and test accurately with just Armour.

I think you tested to soon to actually get true results.

Was the blood test done BEFORE taking T4 med?
If you took the T4 med , that would explain the high T4.
I always fast before bloods and was always told that it is best to do that.
If the labs were done before T4 med then your T4 isnt converting as it should.
There are a number of reasons why that happens.
Start by eliminating each one.

How do you tell if you have conversion problem, I have always suspected that somehting was missing and that is why I felt so miserable. I just switched to Armour 2 weeks ago.  I was on 112mg of Synthroid right before the switch. This was the lowest dosage in 15 years and my highest TSH since TT in 1994.

TSH:             2.396
Free T4         1.68      (.61-1.76)
Free T3          2.8      (2.3-4.2)
T3                 104      (85-205)

Since Free t4 on high end and t3's on lower end, doesn't that confirm my suspicions that T3 is needed?  If not, does anyone know how you compute? Thanks,
