Why Bisphosphonates and PPIs Together Increase Fracture Risk by 52% (and What Works for Bone Health)
Episode Summary
Cole Siefer and Dr. Rose deliver a comprehensive educational deep dive on osteoporosis and bone health. Dr. Rose explains the hormonal mechanisms behind why women are disproportionately affected, the limitations of conventional diagnostics and treatments, how nutrients (vitamin D, K2, calcium) and lifestyle factors interplay with bone density, and what functional medicine can offer in both prevention and partial reversal. The episode includes a patient case study of a 68-year-old woman who was on long-term PPI and bisphosphonate therapy with no improvement, and how a multi-pronged functional approach is moving her in the right direction.
Key Topics
- 1
Why osteoporosis disproportionately affects women (hormonal mechanisms: estradiol and osteoclast/osteoblast balance)
- 2
Difference between osteopenia (T-score -1 to -2.5) and osteoporosis (T-score worse than -2.5)
- 3
DEXA scan explained and its limitations (measures density, not bone quality or architecture)
- 4
Alternative diagnostic: REMS ultrasound scan (non-radiation, provides both BMD and 10-year fracture risk)
- 5
Role of vitamin D (functional target: 60 to 80 ng/mL), calcium, and K2 in bone health
- 6
Conventional vs. functional medicine vitamin D reference ranges
- 7
How K2 directs calcium to bones rather than arteries
- 8
Medications that increase fracture risk: PPIs, SSRIs/SNRIs, synthetic corticosteroids
- 9
The 52% fracture risk increase when bisphosphonates are combined with PPIs (meta-analysis, ~60,000 participants)
- 10
SSRI/SNRI use linked to 68% increased fracture risk (10-year Canadian study)
Quotable Moments
“Unfortunately, it's something that isn't screened for and detected until women are in their 50s and older. If we had a healthcare system that was really proactive and invested in preventive care, we would be catching it much earlier.”
“Sometimes success simply means they haven't fallen, or they fell and they didn't break something.”
“I oftentimes have people coming in with osteoporosis and they just feel a little hopeless. And they really shouldn't. There are other tools out there that do make a difference.”
“There was a study of almost 60,000 people. Those people while taking a bisphosphonate and a PPI actually had an increased risk of fracture by 52% compared to people who were just taking the bisphosphonate.”
“I am on a personal mission to talk to my young female patients and to people who are parents of girls ages eight into their 20s. That is a prime window where we can still really optimize vitamin D and calcium absorption and build a strong foundation.”

FAQ
Bone Health FAQ
Osteopenia means bone density is lower than normal with a T-score between -1 and -2.5. Osteoporosis is more severe with a T-score worse than -2.5, meaning bones are porous, fragile, and significantly more likely to fracture at the hip, spine, and wrist.
Yes. SSRIs and SNRIs are associated with a 68% increased fracture risk according to a 10-year Canadian study. Elevated serotonin inhibits osteoblast (bone-building) activity without reducing osteoclast (breakdown) activity, leading to net bone loss.
K2 directs calcium to your bones rather than arteries. Without K2, calcium absorbed through optimal vitamin D can deposit in arterial walls and increase cardiovascular risk. Taking them together ensures calcium goes where your body needs it.
REMS (Radiofrequency Echographic Multi Spectrometry) uses ultrasound instead of X-ray for bone density. It provides both bone mineral density measurements and a 10-year fracture risk score without radiation exposure, though it is not yet widely available.
Bioidentical estradiol is one of the most effective interventions. Estradiol puts a brake on osteoclast activity, and when estrogen drops at menopause, bone breakdown accelerates dramatically, especially in the 5 to 10 years after menses stop.
It is harder to achieve large gains after 60, but it is not too late. Bioidentical HRT, vitamin D optimization, calcium citrate, weight-bearing exercise, and protein intake can all improve density or slow decline. The goal shifts to preventing fractures.
