5.0 out of 5 stars Great book (German translation)From Jens On January 2, 2017

Since I am very often suffering from extreme muscle pain and but no doctor could call it a cause, I decided to do my own research and came to this book. Extremely well-written and of course also tried everything. After 3 months I can only say that I am much better and my vitamin D mirror despite very high dosage daily is still in the lower range.
