I am due a blood test following an increase in Levo and prescription of Vit D3 supplements. I know to fast on the morning of the blood test drinking water only and to have the test done early in the morning. I will take my Levo at 1.30 pm as normal after the blood test.
Question - I think I have read to stop all Vit B supplements 5 days before the blood test as to not skew the results. As I also take Vit D3 and MK7, B12 and Magnesium Citrate do any of these supplements need to be stopped?
I am going to ask for my cholesterol to be checked and hope that the blood nurse will do it for me rather than go through the GP (she is excellent but can obviously only work within parameters set by the Practice).
I have had all the other things checked like ferritin (was within range but at bottom of range a few months ago) and will start supplements next week. As a Hashi patient should I be taking Selenium? Should I also be taking Zinc? I have got to send off for another load of supplements from Amazon so would be a good time to order all together.
Thank you for reading - I have received wonderful advice since joining. You lovely people are a lifeline!
