As more people take osteoporosis drugs like Fosamax and other bisphosphonates for an extended period, negative side effects are appearing, such as unusual fractures and jaw necrosis. Here's an article that discusses the drugs and some alternative strategies for building bone density.

For me, the primary strategy I am trying this year is the B Strong 4 Life program, featuring the biodensity machine that can safely create osteogenic loading several to many times one's body weight.  For example, last week I was able to press for 5 seconds 1,876 lbs. in the leg press, which is more than 10 times my body weight. Chest press was 491 lbs., core pull was 236 lbs, and vertical lift was 382 lbs. Overall, since I started in Dec. 2013, I have gained 137% in strength as measured by the biodensity machine.  My next bone density scan is in December and I'm hopeful to see an improvement rather than continued loss of bone.

This program is not just for postmenopausal females, but can work for those with health conditions that may cause low bone density, such as untreated celiac disease, eating disorders,  post-cancer recovery, and conditions requiring long-term use of steroids.

Here's an article that a friend passed along to me by a physician, Dr. Fuhrman, about nutritional approaches to protecting our bones.  The article also lists calcium content of various foods, recommends weight bearing exercise (literally, by wearing a weighted vest), and lists some of the side effects of bisphosphonate drugs, such as Fosamax and Boniva.
