Currently taking 100 synthroid and 12.5 cytomel.
Results are:
TSH...suppressed
Free t4: 19.5 (10-25)
Free t3: 5.2 (3.5-6.5)
Feeling a bit cold, tired and water retained...should i stay on 100 synthroid and take maybe 15-20 mcg Cytomel instead of 12.5 mcg to get my free t3 closer to 5.75-6.5???
Many thanks!
Gardenofeden,
There's scope to add another 6.25mcg to the 12.5mcg T3 you are already taking.

How long have you been on those dosages? Just wondering if there's another reason you are cold? Or if you haven't been on that dose for long then it may not have optimised yet.
If it were me......and it's not! ! .....I would hold steady dose for 6 weeks and if cold still then do as you are suggesting 😀
Probably you are there already.
Take care be warm!
How about just switching to natural dedicated thyroid medication that gives you both the t3 and t4 ?
With your TSH very low its pointless taking any T4 as it is actually working against the T3 by turning all the T4 into Reverse T3 and blocking out the T3. I was like this for years until I decided to change to just T3 only and it has worked a lot better for me. It will take as long as 8 weeks for all the Reverse T3 to work out of the system so don't expect instant results if you do change your drugs. I've been on just T3 for over 6 years now and I have no T4 at all in my body.

I should state that i had a total thyroidectomy 16 yrs ago.
I thought in that case, people must be given both t4 and t3, no?
No some of the people on here take just T3, but our bodies are all different and its about how you feel, not the numbers on a sheet. T4 is just a storage hormone which the body uses as a store until the active hormone T3 is required. However the TSH level in your body determines which way the conversion will happen, if your TSH is very low (or suppressed) then the T4 will turn into Reverse T3 which blocks the receptors people are talking about. I understand that your RT3 was fine when tested but bear in mind that this is the value in the blood and not in the tissues where T3 works. The ranges that are quoted on blood tests are from statistics built up over the years of thousands of people and does not factor that some of us are different and our bodies do not work in a standard way.
What is important is how you feel.
Cytomel
Just got updated thyroid hormone results — see why I'm tired. 
Interpreting thyroid results, should I take T3?
Horrible side effect of Cytomel
Adding NDT and dropping Cytomel
