Since my last blood test I’ve gone from 100mg to 125g of levothyroxine, I've taken one B complex tablet a day and I'm also taking two viviscal tablets daily to try and help with the hair loss. I've also been GF for about four months.
The doctor said my vitamin D levels are low, but everything else is looking good. They tested more back in July than this time, I'm not sure why so slightly more limited results below:
TSH - 0.31 mu/L (0.30-4.20)
Thyroid Peroxidase Antibodies - didn't test
Ferritin- didn't test
Follate - 6.1 ug/L (3.0-20.0)
Vitamin B12 - 455 ng/L (180-640)
Vitamin D - 47.6 nmol/L (>50.00)
Any suggestions on actions on the above? When should I next get a blood test and what do I need to ask for? My NHS won't test T3 so should I do a private one to get some more results?
Thank you for your help🙂

With B12 below 500 you need a separate B12 as well as B complex
Then once your serum B12 is over 500 (or Active B12 level has reached 70), you may be able to reduce then stop the B12 and just carry on with the B Complex.
If Vegetarian or vegan likely to need ongoing separate B12 few times a week
IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 5-7 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 folate supplement (eg Jarrow methyl folate 400mcg) and continue separate B12
Post discussing how biotin can affect test results
Retest vitamins at least annually …..and ideally antibodies too
Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins
