I take Calcium, Vitamin D and Magnesium. I saw the Rheumatologist this morning and he prescribed alendronate sodium for the osteoporosis. My dexa scan score was -3.1. He said it would be worse if I hadn't exercised. I've done Pilates through the years, but a lot of the spine flexion exercises risk spinal compression fractures so I'm going to see the Physical therapist for appropriate exercises. The National Osteoporosis Foundation has many videos posted about proper lifting techniques and some handouts on safe exercises and Yoga poses as well, if you're interested.
Also, Bob and Brad, the physical therapists, have podcasts posted on YouTube with Sara Meeks, a physical therapist renowned for her work on osteoporosis. Glad you're feeling better!
