Bone Mineral Density
A measure of calcium and mineral content in bones, used to assess bone strength and fracture risk.
TL;DR
Bone mineral density improves with resistance exercise, adequate protein, and vitamin D/calcium sufficiency. Collagen peptides and vitamin K2 show promising human data for postmenopausal bone loss.
Why It Matters
BMD peaks around age 30 and declines with age, accelerated by menopause. Supplements cannot reverse osteoporosis but support the remodeling environment: vitamin D/calcium correct deficiency-driven loss, collagen peptides improved BMD in a 12-month RCT in postmenopausal women, and K2 reduced fracture rates in Japanese trials. Pharmacotherapy remains standard for osteoporosis.
How to Measure
DXA scan every 1–2 years for those at risk; FRAX score for fracture risk assessment.
Biomarkers
Optimization Protocol
Vitamin D3 to 30–50 ng/mL + food calcium 1,200 mg/day. Collagen peptides 5 g/day (positive 12-month BMD trial). Vitamin K2 (MK-4 45 mg in Japanese trials, or MK-7 180 mcg). Combine with progressive resistance training.
Lifestyle Levers
- •Resistance and impact training
- •Adequate protein (1.0–1.2 g/kg)
- •Fall prevention
- •Limit alcohol; avoid smoking
Supporting Supplements
Calcium
Calcium plus vitamin D reduces fractures in deficient older adults; supplementation in replete adults shows little BMD benefit.
Collagen (Hydrolyzed)
A 12-month RCT showed collagen peptides improved BMD in postmenopausal women.
Vitamin K2
Japanese MK-4 trials show fracture reduction; MK-7 evidence is positive but thinner.
Vitamin D
Correcting vitamin D deficiency slows bone loss; benefit in replete individuals is modest.
