Ya exactly what Freud said, I told my doctor I was going to try it, he advised against it and I went against him being desperate. He ordered the tests for me to take at a private company, my insurance ending up covering it but each test was around 80. He orderd me to get tests every three months to just check on the levels of magnesium and calcium hes not too worried about the Vitamin D. Warning me that too much vitamin D will cause Hyperglycemia. Everyone's bodys are different but I wouldn't take the regimen without those tests every so often and the initial one. Best of luck to you !!
