I am not feeling great and have got myself confused. I am testing Vitamins D, B12 and B9, Magnesium, Selenium, Zinc, Ferritin, Sodium and Calcium tomorrow.
I take iron, vitamin d, fish oils, selenium, magnesium, vitamin c.
I also take a b complex but stopped this a few days ago as it contains biotin. I usually stop everything for 4-5 days but got myself confused.
Should I have left off any of the above before blood testing tomorrow? I can't remember at all.
