I write from Italy where, unfortunately, the doctors do not prescribe to a patient this important exam. I have irritable bowel problems and back pain. I was 22 seconds value of Vitamin D the last blood tests my wife and many friends to whom I have told you to do this exam to 10. Unfortunately I have tried many times to get it but I notice that I have some side effects. Thirst, night cramps with tachycardia, ringing in your ears. I have never exceeded 2,500 Ui day. I take the D3. I assume 125ml. of water each day with a solution of 25gr. of magnesium chloride. How can I overcome these problems?
I hope you understand my English.
Thanks so much.
