Im confused regarding my latest thyroid results I seem to be over on my FT3. I was taking 175mcg of T4 and 40 T3 but recently upped T4 to 200mcg. Any increases I have had in the last year and a half has only slightly raised my T4 and kept T3 the same....sometimes it lowered. I had loading doses of B12 early dec....will this have aided conversion to T3?? And the absorption of T4? After the b12 loading doses my headaches were down to virtually zero but now 6 weeks later they are back. I am 99.9% sure I need more B12 but am now worried it could be T3? Although I have had headaches way before even touching T3. Any thoughts as back at gp tomorrow 😕
Back in Nov results were
FT4 12.5 FT3 5.4
I am now at FT4 22.3 and FT3 7.7 sure the upper ranges are 24 and 6.5ish?
