A clear, evidence-based guide to stronger bones and lower fracture risk
When patients come to me after an osteoporosis diagnosis, the emotion I see most often is not fear. It’s resignation. They’ve been handed a number, maybe a prescription, and the quiet impression that this is just what happens as you age.
I want to challenge that. Bone is living tissue. It is constantly remodeled, and it responds, meaningfully, to what you do, what you eat, how you move, and how you support your hormones. Even after bone loss has begun, there is a great deal you can do to improve bone strength and reduce fracture risk.
Here is what actually matters.
Bone is constantly being broken down and rebuilt. Osteoclasts are the cells that resorb old bone; osteoblasts are the cells that lay down new bone. In healthy younger adults, these two processes stay in balance. Over time, and especially after menopause, the balance shifts toward more breakdown and less rebuilding.
The drivers of that shift include:
- Declining estrogen (the single biggest driver in women)
- Age-related changes in remodeling efficiency
- Inadequate protein intake
- Sedentary lifestyle
- Smoking and excess alcohol
- Certain medications, particularly long-term steroids
One thing I always emphasize: bone density is only part of the story. Bone quality, muscle strength, balance, and fall risk all determine whether a fracture actually occurs. Our goal is not just improving a number. It’s preventing fractures and preserving independence.
How to Read a DEXA Scan Without Overinterpreting It
A DEXA scan measures bone mineral density (BMD) and is the standard tool for diagnosis, but it has to be interpreted carefully. The key sites are the lumbar spine, total hip, and femoral neck. A T-score at or below -2.5 meets the diagnostic threshold for osteoporosis.
What I want patients to understand is that a lower T-score indicates higher fracture risk, but a one-point drop in T-score does not translate into a fixed, predictable increase in risk for every individual. Risk depends on age, prior fractures, medications, and fall risk. The number alone does not tell the whole story.
Practical guidance for DEXA follow-up:
- Always compare scans from the same machine and facility
- Look for the trend over time, not just a single snapshot
- Avoid repeating DEXA more often than every two years
Other Testing That Actually Helps
Beyond the DEXA, a few labs give us genuinely useful information.
25-Hydroxyvitamin D
This is the best marker for overall vitamin D status. Deficiency impairs calcium absorption and bone remodeling, so correcting it matters.
Bone Turnover Markers
CTX (C-terminal telopeptide) reflects bone breakdown; P1NP (Procollagen type 1 N-terminal propeptide) reflects bone formation. These are most useful for monitoring treatment response rather than making a diagnosis, and they can tell us early whether a therapy is working.
Basic Labs When Indicated
Depending on the clinical picture, I may also check calcium, kidney function, alkaline phosphatase, testosterone in men, thyroid function, and parathyroid hormone (PTH). Secondary causes of bone loss are worth ruling out.
Lifestyle: The Non-Negotiable Foundation
These are not optional additions to a bone health plan. They are the base layer. No supplement or medication works as well without them.
- Stop smoking
- Limit alcohol
- Maintain adequate calorie and protein intake
- Reduce fall risk through vision correction, balance training, home safety review, and medication assessment
Exercise: The Most Underused Treatment
Exercise may be the most powerful tool we have for bone health, and it is chronically underutilized. I see patients given a list of supplements before anyone has asked them about their activity level. That’s backwards.
What the evidence supports:
- Resistance training (strength training), the most important category
- Impact and weight-bearing exercise, as tolerated
- Balance training to directly address fall risk
The expected benefit from exercise is modest improvement in bone density, but significant improvement in strength, stability, and fall prevention, which is ultimately what protects you from fracture.
A word on weighted vests: there is some evidence they can help preserve hip bone density when combined with impact exercise. However, the data is limited and they are not part of standard clinical guidelines. However, if you are a regular walker with concerns about your bone density, there is absolutely no reason not to incorporate this.
Diet: Simple, Foundational, Effective
Diet for bone health does not need to be complicated. The essentials are adequate protein (often dramatically underconsumed in older adults), adequate calcium, and an overall nutrient-dense eating pattern.
On calcium: I always recommend food first: dairy, leafy greens, fortified foods. Supplement only when dietary intake is genuinely insufficient. Unnecessary high-dose calcium supplementation carries its own risks, and at minimum often causes GI upset.
Hormone Replacement Therapy: A Nuanced but Important Option
HRT is one of the most misunderstood topics in women’s health, and I want to address it directly. For the right patient, women with no major contraindications, HRT offers a roughly 30–40% reduction in fracture risk while on therapy. That is a meaningful number. Women are often told that if they are 10 years past menopause this is not an option. While it is not guideline supported, HRT can be safely started in later years, it just requires a slow and careful approach.
HRT is not appropriate for everyone, and it requires individualized risk assessment (as we do in our 90 day Hormone Program). But for eligible women, it deserves serious consideration as part of a comprehensive bone health strategy.
Supplements: What Helps vs. What Only Sounds Helpful
This is where I spend a lot of time in appointments, because the supplement market for bone health is full of noise. Let me be direct about what I actually use clinically.
The Ones I Rely On
Vitamin D3 (cholecalciferol) supports calcium absorption and bone remodeling. It is not a standalone treatment, but correcting deficiency is foundational.
Calcium: I prefer calcium citrate for most patients. Better absorption and more flexible dosing. Calcium carbonate works too, but should be taken with meals.
Magnesium: Glycinate or citrate forms are best absorbed. Magnesium oxide is commonly sold but poorly absorbed and not my first choice.
Protein: Underappreciated and critically important. I cannot overstate how often I see older adults, especially women, eating far too little protein.
Vitamin K: Mixed Evidence
Vitamin K2 is widely promoted for bone health, and the story is compelling, but the evidence is more mixed than the marketing suggests. MK-4 has some fracture data from high-dose Japanese studies; MK-7 has a longer half-life and is the common supplement form, but its fracture outcome data is less robust. I consider it a reasonable supportive nutrient, not a proven fracture-reduction therapy on its own.
Trace Minerals
Zinc, copper, boron, and silicon are all involved in bone metabolism. They are worth addressing if deficient, but they are not primary interventions.
Strontium Citrate: Proceed With Caution
This one requires a direct conversation. Strontium is heavier than calcium and increases X-ray absorption, which means it makes DEXA scans look better even when bone strength has not proportionally improved. The result is artificially inflated scores that make it nearly impossible to track real progress over time or compare scans meaningfully. I do not recommend strontium citrate for this reason.
When Medications Make Sense
Medications are appropriate when fracture risk is genuinely high, including patients with a prior fragility fracture, a T-score at or below -2.5, or an overall elevated risk profile. Here is a brief overview of the main categories.
Bisphosphonates (Alendronate, Zoledronic Acid)
These are the most commonly prescribed class. They reduce vertebral fractures by roughly 70% and hip fractures by about 40%. The main concerns with long-term use are oversuppression of bone remodeling and an actual increase in atypical fractures. Duration of therapy is an important conversation. This class of medication also has common, unpleasant side effects.
Denosumab (Prolia)
Denosumab shows similar fracture reduction numbers: about 68% for vertebral and 40% for hip. The critical caveat: stopping it abruptly can cause rapid bone loss and rebound fractures. If you start Prolia, you need a transition plan.
Anabolic Therapies (Teriparatide, Abaloparatide)
These bone-building agents are reserved for severe osteoporosis and high-risk patients. Abaloparatide has shown up to 86% reduction in vertebral fractures in clinical trials. They are injected, time-limited therapies, but genuinely impressive for the right patient.
SERMs and Calcitonin
Raloxifene (a SERM) reduces vertebral fractures but is not effective for hip fracture prevention. Calcitonin has a minimal role in current practice and I rarely recommend it.
One principle I always keep in mind: more bone density does not automatically mean better bone. Some treatments increase density without proportionally improving bone quality. Fracture reduction data and long-term safety profile matter more than the number on a DEXA.
A Practical Approach, Step by Step
When I work through bone health with a patient, the process generally looks like this:
- Confirm the diagnosis and interpret the DEXA scan in full clinical context
- Check vitamin D and consider bone turnover markers (CTX and P1NP)
- Optimize diet and protein intake
- Begin strength training and balance work
- Address fall risk specifically
- Consider HRT or medication if overall fracture risk is high
- Reassess over time. DEXA no more often than every two years
The Bottom Line
Osteoporosis is not a passive condition. It is highly modifiable, and the patients who do best are the ones who approach it that way. The most effective strategy is not one single intervention. It is a layered approach: nutrition, movement, hormonal balance, and targeted medical therapy when needed.
With the right approach, it is absolutely possible to slow bone loss, build strength, and meaningfully reduce your fracture risk. That is what I work toward with every patient who comes to me with this diagnosis.
