Some folks manage with a top of range FT3 and low FT4. Others need their FT4 well over half way through range along with their FT3 to feel well.
If you are symptomatic and feel a higher FT4 is needed then you will need to add some levothyroxine.
As your FT3 is at the top and sometimes over range you may want to reduce NDT a little first as adding T4 will increase FT3 a little depending on how well you convert.

So, how much NDT were you taking at the time you tested on 21.05? I wouldn't describe excess T3 as 'toxic' exactly, not at that level. Many people need their FT3 slightly over-range to feel well. But you wouldn't want it very high for very long. That would be bad for your heart. But, I don't think you need to worry at your level.
Why are you testing every month if you're not changing your dose? And, if you are changing your dose, you need to be on that dose for six weeks at least before testing.
FT4 will always be lower on T3 than if you took T4 only.
I think you mean 'grain', not 'gram'. NDT is measured in grains.
That's a lot of chopping and changing in a very short time. Which, means that your monthly blood tests are not going to tell you the full story. I think you need to stop changing your dose, and stay on the dose you're taking now for the next six weeks, and then retest, see where you are.
People with thyroid hormone resistance need a high dose of T3 with high FT3....mine sends medics running for the hills! But I need it to be high to function....scientifically proved.
But you're right, high FT3 should otherwise be avoided
The T3 in NDT is raising your FT3....although some people need high FT3 if they have a type of hormone resistance. I am one.
Your ferritin is too low
Have you tested folate, vit D and vit B12
These nutrients should all be optimal for good conversion and thyroid health
I suggest that first, you test your nutrient levels, optimise them and you might try lowering the NDT and adding some levo.....but difficult to say without pre NDT labs
Do you have a copy of your diagnostic labs (first test before medication) if so post a copy for advice. This will help evaluate your thyroid status?
Sorry, so many questions but the answers provide the clues !
I'm not a medic just somebody else who has travelled the bumpy thyroid road looking for answers.
B12 was still lower than optimal - needs ot be at least 500, ferritin pretty bad - needs to be about 70-80. Folate OK. But if your vitamin levels have got better, your conversion of T4 to T3 has probably improved.
I use a B12 spray from "Better You" (Amazon) recommended by another member.
I sympathise with your reaction to iron pills, I've never found a really satisfactory solution, though magnesium citrate does help. I stir it into my breakfast orange juice!
Magnesium baths can also help.
Medics know very little about the importance of nutrients and how they support the body's functions....."just eat a well balanced diet" is often their advice ! Hmmmm!
Keep an eye on your FT3 result it may help to lower your NDT a little. You need to leave 6-8 weeks between a change of dose to allow the body to adjust to the change, I think your body may be a bit confused by all the recent changes you've made!
I'd suggest saying on current dose for a few weeks while you optimise your nutrients
Just a few thoughts, others probably have better suggestions!
I feel better but ufortunately still get the same symptoms. I feel calmer when taking LDN.
I have a lot of energy one day and then next day I am like a flat tyre...but I do not have any muscle, shoulder pains as I used to have previously.
I will read those articles. I had B12 tested by NHS around 3 years ago, it came back as normal apparently....I did not know any better....
I actually thought that my B12 is slightly too low after looking at the recent tests.
Thank you for all your advice.
I try to eat chicken liver every so often, take 50mg iron pills which not supposed to cause constipation in fact...well, at least i know that my iron is low....
Apparently some people buy dried liver....I never checked it....
Would you say that I do not need to be worried about slightly higher FT3?
