I'll be going for my annual thyroid blood test (I was over active a few years ago) and will ask my gp to also test folate, ferritin, potassium (which was slightly below range last year) and vitamin D.
I supplement folate (or a vitamin B complex) and Vitamin D (in winter) on a daily basis. I eat as much potassium rich foods as I can and about once a week have a spatone iron supplement in a glass of orange juice.
I si weekly and mostly feel well on that
Should I continue taking the supplements as usual before the blood test or should I leave off for a few days or weeks?
