It really means complete elimination or drastic reduction in anything high in calcium, even water can have quite a bit. But this was, again, with extremely high doses. I don't currently follow the protocol, as I do other things, but I sometimes take high doses for a few days.
When I had my first major flare-up, I tested at 7ng/dl (near bottom half of the severe deficiency range). That's what lead me to pay attention to this subject.
I have been diagnosed with some autoimmunity issues and would love to try this. How did you identify that vitamin d might help with yours?
