I posted here a few weeks back after I had some private blood tests done and shared the results with my GP.
I ordered some T3 online, and it arrived today! I'm nervous to try it without being directly prescribed, but I'm certain that just increasing my T4 (levothyroxine) wouldn't help (which is what my GP suggested) as I'm already out of the top end of fT4 range. My TSH could do with being lower, so I wonder if I do increase the T4 as per my GP advice, or just try the T3.
I'm on 150mcg levothyroxine Daily and take 1x210mg ferrous fumarate bd. And added 5000IU vitamin D daily after I got these test results. I'm also taking a selenium supplement but I can't remember the dose, and I don't have it nearby.
I read it is suggested to reduce T4 by 50mcg and add 10mcg T3 replacement, but I wonder as my TSH is a bit higher than I would like, I should stay at 150mcg T4 and just add the T3. I have 25mcg T3 tablets - should I half/quarter them and see how I go? Any advice is greatly appreciated.

Interestingly, my ferritin came back as 143.8 when it was 55 only 2 weeks earlier... the only thing I did was cut out dairy and gluten in case it was slowing iron absorption.... I am going to retest again in a couple of months.
Chrissie78 You definitely shouldn't increase Levo as your GP suggests, that would put you in danger of creating more reverse T3 and you already have enough!
My suggestion is to reduce Levo by 25mcg and add in one quarter of a T3 tablet - 6.25mcg. T3 is approximately 3-4 x the strength of Levo, so 6.25mcg T3 is roughly equivalent to 18.75-25mcg Levo. That should bring your FT4 down a bit. Stay at that for two weeks then add in another 6.25mcg T3. I would then stay at that for 6 weeks and retest. Some people only need a bit of T3, others need plenty more. Some need lots of tweaking with Levo and T3. It's trial and error.
With a reverse T3 that high you might find you need more T3 and less Levo to bring it down. I'm still tweaking after 18 months and haven't found the perfect place yet!
Hi Chrissie and sorry to jump on the band wagon but I just posted an almost identical question. can I ask seasidesusie I did the first add of 6.25mcg of t3 and lowered 25mcg t4 13 days ago and after reading this looking at adding the 2nd dose 6.25mcg t4 tommorow. Do I lower my t4 by another 25mcg. sorry if it is obvious but I don't want to mess this up.... thank you for any advice x
