My endo prescribed 20mcg T3 to go with my 100mcg T4 from July 17 and I have a new set of blood test results in.
My FT3 is down to 4.2 which is lower than before I added the T3 when it was 4.6 and in Aug17 it was 4.8. The 0.2 increase last year was life changing. Though interestingly I don't feel as bad at 4.2 now as I did when FT3 was 4.6 when I started. Could my tissues be drinking up the T3 and leaving not much free ?
From 25 Dec to 04 Jan I took Teva T3 rather than Mercury Pharma T3 and it really didn't work for me, I was noticeably lower and slower and I was having heart palpitations all day long. Could have skewed my results 3 weeks later ?
Now I'm still not feeling as well as I did Q4 17.
Why might my FT3 have dropped ?
Should I up my T3 dose ? And if so by how much ?
My ferritin, folate, Vit B12 and Vit D are up marginally from when I started on T3, though I know from reading here that they are low.
