I was diagnosed with hypothyroidism in November 2023 and started on a 50mcg dose of Levothyroxine. In March this year, my GP increased this to 75mcg (50mcg Accord and 25mcg Mercury Pharma). This week I took a private blood test to check my latest thyroid and vitamin status. These are my latest thyroid results:
TSH: 3.64 mU/l (Range 0.27 - 4.2) 85.75%
FT4: 17.5 pmol/l (Range 12 - 22) 55.00%
FT3: 3.8 pmol/l (Range 3.1 - 6.8) 18.92%
My GP is keeping me on 75mcg for the next 8 weeks at least. My understanding from many helpful posts on this forum is that my TSH should be nearer 1 and that my FT3 is too low. Is that correct?
Should I get my key vitamins to an optimal level before asking my GP for a Levo increase? I weigh around 57kgs. My vitamin results are:
Ferritin 99.3 (30 – 332)
Folate Serum 19.8 (7 – 35)
Vitamin B12 Active 91.9 (37.5 – 188)
Vitamin D 81.9 (50 – 250)
All 4 came back from the test marked as normal, but some look on the low side to me. I would appreciate advice on whether I should be supplementing. I don't currently take any supplements.
Thanks for your help.
