It cut death from all causes by 28% in a landmark trial — and nobody could explain why. Now scientists are discovering it may be one of the most powerful anti-aging drugs ever prescribed.
In 2007, something unexpected happened inside a clinical trial at Duke University.
The study was straightforward. Researchers were testing whether a once-yearly infusion of zoledronic acid—a bisphosphonate, a class of drugs designed to strengthen bones—could prevent repeat fractures in patients who had already broken a hip. It could. The drug reduced new fractures by 35%.
But that wasn’t the surprise.
When the researchers tallied the mortality data, they found that patients who received the drug were 28% less likely to die from any cause during the study. Not just from fractures. From anything.
The finding, published in the New England Journal of Medicine, stunned the osteoporosis community. A bone drug—reducing death from all causes? The numbers were so unexpected that the lead investigators initially suspected a statistical error. It wasn’t.
Nearly two decades later, the evidence has only grown stronger. And the implications extend far beyond bone health.
Bisphosphonates have two rare side effects: atypical femoral fractures and osteonecrosis of the jaw (ONJ). What’s more, the risk increases the longer you take them. If anyone here is currently on bisphosphonates, please share your experience!
Additionally, bisphosphonates should be avoided during dental implant procedures, as they may lead to implant failure.
Not yet. I had ACDF surgery December 2025. I will likely start January 2027, and take it for a year, then take a break. I may repeat that 1 year course a couple more times when I hit my 70’s… but once I do hit my 70’s there may be more research or superior interventions, in which case I will re-evaluate. I’m speculating that these drugs are more useful later in life anyway 70’s-80’s. YMMV.
