Bisphosphonates accumulate in your bone. When OsteoClasts gobble up your bone, bisphosphonates are released into the Osteoclasts and disable or kill the Osteoclasts. This is great news when the problem is Osteoclasts Gone Wild. Bisphosphonates preserve bone by slowing down bone resorption. However, after a few months, bone formation by OsteoBlasts also slows down, resulting in slow bone turnover.
Moderate and balanced bone turnover is good. You repair microcracks in your bone when OsteoClasts resorb the bone around them and OsteoBlasts fill in the void with new bone matrix. A mix of new and old bone is far stronger than all old bone. Some OsteoClast activity is necessary to heal fractures, especially incomplete (stress) fractures. That is where long term bisphosphonates can be too much of a good thing.
