Was test done early morning, ideally just before 9am and last dose levothyroxine 24 hours before test
How much levothyroxine are you currently taking
Do you always get same brand levothyroxine at each prescription
TSH is quite high for someone on levothyroxine. You possibly need small dose increase
What vitamin supplements are you currently taking
No ferritin or vitamin D results?
B12 and folate are both too low
supplementing a good quality daily vitamin B complex, one with folate in (not folic acid) .This can help keep all B vitamins in balance and will help improve B12 levels too
Thorne Basic B recommended vitamin B complex that contains folate, but they are large capsules. (You can tip powder out if can’t swallow capsule)
IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results
In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate methyl folate supplement and continue separate B12
With serum B12 result below 500, (Or active B12 below 70) recommended to be taking a B12 supplement as well as a B Complex (to balance all the B vitamins) initially for first 2-4 months.
once your serum B12 is over 500 (or Active B12 level has reached 70), stop the B12 and just carry on with the B Complex.
Hi Adam, Suggest you get tested for Coeliac.....even if you've been tested before.
"Determine whether there is an underlying cause for the vitamin B12 or folate deficiency — this may require specialist referral.
If folate levels are low, assess dietary folic acid intake, and if history suggests malabsorption, check for coeliac disease by testing for antiendomysial or antitransglutaminase antibodies (depending on the local laboratory).
The main cause of folate malabsorption is gluten-induced enteropathy."
