I've ordered thyroid and vitamin (B12, ferritin, fplate and D3) test from medichecks. I've just read on a post today that you should stop iron supplements for a week before you test your ferritin to get any iron out of your system. As I also supplwmwnt D3 and good vitamin B complex daily, does anyone know if I also need to stop these supplements for a week before I do the bloods?
Advice much appreciated. I am new to all this and was diagnosed with Hashis three weeks ago. Having gone gluten free a couple, of weeks ago and started a shedload of supplements, I do feel much better. I'm reluctant to stop the D3 and B vitamins for a week if it's not necessary.
Many thanks in advance.
