Hi @melia7, both my husband abd I have osteoporosis and are taking alendronate. Our doctors advised calcium supplements. I've also read about the problems with calcification resulting from them. It's all so confusing , isn't it? Dr. Loren Fishman (Columbia University School of Medicine) doesn't think anyone over 75 should take more than 500 mg of calcium a day. I've increased the calcium we eat from dietary sources and take that into consideration with the supplements we take. We also take Vitamin D, Boron, Vitamin K, and I just started a collagen supplement as well. Also trying to keep up the dark leafy greens. and exercise.

Dr. Fishman has an ongoing study of yoga poses that increase bone density, Twelve Poses vs Osteoporosis, which you can google, if interested. Take care.
