Testing advice after trialling T3

[TiredMummy]

Hi all,

I’ve managed to stay on T3 for a while now and I’m getting ready to do a thyroid test. I take two doses of T3, one around 6am with my Levothyroxine and the second T3 dose at 2pm. If I do my test 8am I’d imagine it’s fine as far as the Levo is concerned but is this gap OK for the T3? And is it just 48 hours before the test I need to stop taking vitamins if I’m not taking biotin?

Managing to stay on T3 for this time around is a huge miracle for me! I am feeling the benefit but it doesn’t feel like I’ve quite got my levels right yet.

Thank you! x

Great News about your T3 experience. No doubt plenty room for tweaking. Gently does it.

TiredMummy,

I'm pleased adding T3 is now working for you.

Regarding testing see my post here ... healthunlocked.com/thyroidu...

how much T3 are you taking

Ideally split T3 as 3 doses with last dose at 8pm

Stop any supplements that contain biotin (eg vitamin B complex) 5-7 days before testing

If taking iron stop this a week before testing iron levels

Other vitamins, just stop 24 hours before testing

I started with 2.5mcg, then worked up to 10mcg. I take 5mcg 6am and then 5mcg 2pm. I tried dropping back to just 2.5mcg at 2pm but that makes me feel very hypothyroid. Should I try splitting the second 5mcg into 2 doses so I am dosing 3 times daily? When I tried T3 previously in the evenings it kept me awake but perhaps my body will adjust?

Just try it the day before test

So 5mcg 6am, 2.5mcg at 2pm and 2.5mcg at 8pm

Do not test until the afternoon, right before your second dose. Either that, or do not take your morning T3 until after the morning blood test. I’ve always done afternoon testing.
