Make sure and I learn this from Mrs D it is a good absorbed magnesium. Not the oxide form that does not do as much. I order mine online gylcinate but I know Mrs D often mentions slowmag.I would go to the endocronolgist.Mine didn't do much for me though she did the 24 hour calcium testing and for other missing minerals. She ordered another bone density and I have osteoporosis but this is seperate from the pain condition. Feel beeter
