@susan73 Can you discuss with your doctor taking Vit K (specifically MK4) ? The Japanese have been using this for years against osteoporosis and have done studies that you can access on PubMed to take and discuss with your doc. Also there are new studies about the use of specific types of collagen that increase bone density that are very promising. These are the two main more natural approaches that I can think of that might not stress your kidneys so much, but please discuss with your doc....
