Latest blood test on t4/t3

Hi guys,

After a few months of trying t4/t3 and still not feeling good I have got my bloods tested and now switching back to thyroid s.

My latest blood results are ,

Tsh 0.05

FT4 17.5

Ft3 4.6

Vit D 65

Apparently folate is low but she didn’t give me those results just rushed me off the phone saying she will send me a prescription for that.

I have been taking 100mcg of levo and 50mcg of T3. I feel generally rubbish, skin is awful, hair falling out, gaining even more weight, not sleeping well, bla bla bla the usual symptoms.

I have decided to switch back to thyroid s, what dose would be good to start the switch ?

Was test done as early as possible in morning before eating or drinking anything other than water and last dose levothyroxine 24 hours before test

That’s high dose of T3

Did you split dose into 3 smaller doses day before test. Taking roughly equal 8 hour intervals and last 1/3rd of daily dose 8-12 hours before test?

Vitamin D is too low

Was B12 and ferritin tested

What vitamin supplements are you currently taking

Yes 24 hours for levo and test done at 8am before any food or drink. Last split T3 dose was 12 hours before test.

Are you on strictly gluten free diet and/or lactose free diet

I do try but recently no, we have just moved house and my diet has included a lot of bread for convenience

There’s loads of good gluten free breads available

Use separate toaster for gluten free bread or a toaster bag (from coeliac U.K.)

I will do, we are slightly more settled now so life is easier.

In regards to the thyroid s, I have taken a dose of 1.5 tablets to start but think maybe it should be more ?
