That's interesting, but I can say with great confidence that I was deficient in none of those micronutrients. I even took some supplements of them with the Vitamin D (Magnesium, Zinc, B Vitamins).
I also noticed that things deteriorated irrespective of source of Vitamin D (sun in the summer vs. supplements in winter). Effects were about the same.
So that's why I think, in my case, adverse effects of Vitamin D were neither due to deficiencies nor due to taking the unsulfated version. It must be something about the Vitamin D itself. Plus it was much worse at those times when I took calcium supplements with the Vitamin D, so I believe the effect is because of Vitamin D improves calcium absorption.
From whatever angle I approach the issue, I always become convinced that there is a real issue with calcium, at least in some CFS patients.
