Nutrition & lifestyle
Calcium, vitamin D, protein, exercise, and fall prevention are the foundation of bone health โ necessary for everyone, and the base on which medication works. They are also the area where marketing outruns evidence, so here is what genuinely helps, and what doesn't, graded plainly.
Key takeaways
- Adequate calcium and vitamin D are the foundation โ necessary for everyone, but not a treatment for high-risk osteoporosis on their own.
- Get calcium from food first; add a supplement only to fill the gap.
- Weight-bearing and resistance exercise, plus fall prevention, are among the highest-value lifestyle steps.
- Marketed "bone-builder" supplements โ strontium, algae-derived calcium, and others โ do not have the evidence to replace proven care.
Calcium & vitamin D
Calcium is the raw material of bone; vitamin D lets your gut absorb it. Together they are the base layer of every osteoporosis plan โ and ensuring adequacy is recommended for all adults, regardless of fracture risk. But they are a foundation, not a cure: in high-risk patients, calcium and vitamin D support medication rather than replace it.
- Calcium: most adults over 50 need roughly 1,000โ1,200 mg/day from all sources. Food is the best source โ dairy, fortified plant milks, leafy greens, tofu, canned fish with bones. Supplement only the shortfall; more is not better, and very high supplemental doses offer no added bone benefit.
- Vitamin D: commonly 800โ1,000 IU/day for older adults, adjusted to blood levels. We check 25-OH vitamin D and repletion where it's low, because deficiency undermines everything else.
What this means for you
Add up your dietary calcium before reaching for a bottle โ many people already get most of what they need from food and only need a modest supplement. If you're unsure, we can estimate your intake and check your vitamin D level rather than guess.
Protein & diet
Bone is roughly half protein by volume, and adequate dietary protein supports both bone and the muscle that protects against falls โ a point that matters especially for older adults, who often under-eat protein. A balanced diet with enough calories, fruits and vegetables, and protein spread across the day supports bone health; extreme or very-low-weight diets undermine it (low body weight is itself a fracture risk factor). There is no single "bone diet" that substitutes for the fundamentals.
Exercise & fall prevention
Movement helps bone and, just as importantly, helps you avoid the fall that breaks it. Two kinds of activity matter most:
- Weight-bearing and resistance exercise โ walking, stair-climbing, and progressive strength training load the skeleton and help maintain bone and muscle.
- Balance and mobility training โ practices such as tai chi improve balance and reduce falls.
Fall prevention is a therapy in its own right: review medications that cause dizziness, correct vision, address home hazards (rugs, lighting, grab bars), and treat conditions that impair balance. For patients who are significantly under-treated or exhausted, we pace activity sensibly while optimizing treatment โ then get them moving. None of this replaces medication for high-risk disease, but it treats the whole person and measurably lowers the risk of a fracture.
Supplements & myths
This is the area where claims most outrun evidence. Patients ask about these constantly, so here is an honest accounting โ graded by what the published evidence supports, not by what is marketed.
Strontium supplements (strontium citrate)
Grade D ยท Not advisedAlgae-derived / "plant" calcium (e.g., AlgaeCal)
Grade E ยท Insufficient"Bone-builder" supplement stacks (vitamin K2, boron, silica, collagen, etc.)
Grade E ยท InsufficientHow we grade evidence. From established, guideline-supported care (A) through moderate (B) and conflicting (C) to experimental (D) and insufficient (E). A supplement having a plausible mechanism, or nudging a lab value, is not the same as preventing fractures.
