Key nutrients for bone health
The compounds with the strongest evidence for bone density and skeletal strength.
Calcium
Grade A1000–1200mg/day (food + supplement)
The primary mineral of bone matrix. Supplementation reduces fracture risk by 12–15% in older adults. Food sources (dairy, leafy greens, sardines) are preferred — supplement only the gap.
Vitamin D3 + K2 (MK-7)
Grade AD3: 2000–4000 IU + K2: 90–180mcg/day
D3 increases calcium absorption from 10–15% to 30–40%. K2 directs calcium into bone and away from arteries. The combination is significantly more effective than D3 alone for bone mineral density.
Magnesium
Grade A300–400mg/day
Required for vitamin D activation and calcium metabolism. 50–60% of body magnesium is stored in bone. Deficiency impairs bone mineralisation and increases fracture risk independently of calcium.
Collagen Peptides
Grade B5–15g/day
Type I collagen is 90% of bone organic matrix. Supplementation increases bone mineral density and reduces bone resorption markers in postmenopausal women in RCTs.
Boron
Grade B3–6mg/day
Reduces urinary calcium and magnesium excretion. Increases oestrogen and testosterone levels — both critical for bone density maintenance. Found in fruits, nuts, and legumes.
Silica (Silicon)
Grade B10–25mg/day
Required for collagen synthesis and bone mineralisation. Higher dietary silicon intake is associated with greater bone mineral density in epidemiological studies.
6 natural strategies with strong evidence
Ranked by effect size across the best available research.
Weight-bearing and resistance exercise
The most effective non-pharmacological intervention for bone density. Resistance training increases bone mineral density by 1–3% per year in postmenopausal women. Impact activities (jumping, running) stimulate osteoblast activity more than low-impact exercise.
Optimise vitamin D and K2 status
Target serum 25(OH)D of 40–60 ng/mL. Most adults need 3000–5000 IU/day. Pair with K2 (MK-7) to direct calcium into bone. Test annually — deficiency is the most correctable bone risk factor.
Adequate dietary protein
Protein provides the organic matrix of bone. Low protein intake (<0.8g/kg/day) accelerates bone loss. Higher protein intake (1.2–1.6g/kg/day) is associated with greater bone density and reduced fracture risk in older adults.
Reduce alcohol and caffeine
Alcohol >2 drinks/day reduces osteoblast activity and increases fracture risk by 40%. Caffeine >400mg/day increases urinary calcium excretion. Both are modifiable risk factors with dose-dependent effects.
Quit smoking
Smoking reduces bone mineral density by 5–10% and doubles hip fracture risk. Nicotine directly inhibits osteoblast function. Bone density begins to recover within 1–2 years of cessation.
Fall prevention strategies
Hip fractures in older adults carry 20–30% one-year mortality. Balance training (tai chi, single-leg standing) reduces fall risk by 23–40%. Home hazard assessment and adequate vitamin D reduce falls independently.
Modifiable risk factors for bone loss
The factors that accelerate bone loss — and the natural approaches with the best evidence for each.

Sarcopenia Prevention: Maintaining Muscle After 50
Muscle and bone loss are closely linked — the same strategies that preserve muscle protect bone density.
Healthy Aging After 50: The Evidence
Bone density peaks in your 30s — evidence-based strategies to slow loss and maintain skeletal strength.
Vitamin D3 and Health
Vitamin D3 is essential for calcium absorption and bone mineralisation — deficiency accelerates bone loss.
Skin Nutrition and Collagen
Collagen is the structural protein of bone — the same nutrients that support skin also support skeletal matrix.
