Osteoporosis
Bone disease causing decreased bone density and increased fracture risk.
TL;DR
Silent until a fracture happens. Postmenopausal women and adults over 65 should be screened (DEXA scan). Resistance exercise, adequate protein, calcium, vitamin D, and not smoking are the foundation; medication halves fracture risk when density is low.
Overview
Osteoporosis is the silent thinning of bone structure until fractures occur with minimal trauma — typically the hip, spine, or wrist. Bone density peaks around age 30 and declines thereafter, accelerating sharply in women after menopause. Because it produces no symptoms until a fracture, screening and prevention matter more than symptom-watching.
Common Symptoms
- •No symptoms until fracture (hence silent disease)
- •Fragility fractures: hip, wrist, spine
- •Height loss and stooping (vertebral compression)
- •Back pain from vertebral fractures
- •Receding jawbone / loose teeth in some cases
Common Causes
- •Menopause (estrogen loss accelerates bone resorption)
- •Age-related bone loss
- •Long-term corticosteroid use
- •Low dietary calcium and vitamin D
- •Sedentary lifestyle and low muscle mass
- •Smoking and excess alcohol
- •Certain conditions: coeliac, hyperthyroidism, hypogonadism
Root Causes
Bone is constantly remodeled: osteoclasts resorb, osteoblasts rebuild. Osteoporosis develops when resorption outpaces formation — driven by estrogen withdrawal, aging, inactivity (bone responds to mechanical load), and inadequate raw materials (calcium, vitamin D, protein).
How It's Diagnosed
Diagnostic Markers
- DEXA scan: T-score -2.5 or below defines osteoporosis
- FRAX score: 10-year fracture probability
- Vitamin D level (25-OH): target 30-50 ng/mL
- Calcium, phosphate, ALP: rule out metabolic bone disease
- TSH and coeliac serology when risk factors suggest secondary causes
When to See a Doctor
Ask for a DEXA scan if you are a woman over 65, a man over 70, postmenopausal with risk factors, have taken steroids for 3+ months, or have had any fragility fracture after 50. A first fragility fracture strongly predicts the next.
Supplements Studied For This
Collagen (Hydrolyzed)
Reasonable adjunct to calcium, vitamin D, and exercise — not a treatment by itself.
Vitamin K1
The bone evidence people cite for "vitamin K" comes from K2 menaquinone trials; K1 itself has been tested at high dose and did not deliver.
Strontium
The drug form worked but had cardiovascular harm; the supplement form is untested. DEXA improvements are largely an artifact.
Diet & Lifestyle
Suggested Pattern
Bone needs adequate protein (often underestimated in older adults), calcium from food first, and sufficient vitamin D. Very-low-protein and heavily restrictive diets accelerate bone loss.
Eat more
- Dairy or fortified alternatives (calcium + protein)
- Oily fish (vitamin D, omega-3)
- Leafy greens (calcium, vitamin K)
- Adequate protein at each meal (1.0-1.2 g/kg in older adults)
- Prunes — small trials show bone-protective effects
Avoid
- Excess alcohol
- Very high caffeine intake with low calcium
- Excess sodium (increases calcium excretion)
- Chronic cola consumption (linked to lower bone density)

Frequently Asked Questions
Who It Affects
Osteoporosis affects roughly 1 in 3 women and 1 in 5 men over 50 worldwide; a hip fracture carries a 20-30% one-year mortality in the elderly.
Highest risk: postmenopausal women, especially of European or Asian ancestry, low body weight, family history, steroid users, smokers.
Lifestyle Tips
- •Resistance and weight-bearing exercise 2-3x weekly — bone adapts to load
- •Vitamin D 800-2,000 IU daily if levels are low
- •Get calcium from food where possible (1,000-1,200 mg/day total)
- •Stop smoking — a major bone toxin
- •Fall-proof the home: fractures, not density, are the real enemy
- •Take osteoporosis medication if prescribed — fracture risk reduction is large
