Bone
Skeletal density, structure, and mineral health.
Overview
Bone is living tissue that provides structure, protects organs, stores minerals, and remodels throughout life. Bone strength built earlier and preserved later determines fracture risk in aging.
Why it matters
Fractures — especially hip fractures in older adults — are a major cause of disability and mortality. Bone health is highly modifiable through loading, nutrition, and fall prevention.

Frequently asked questions
Is calcium supplementation necessary?
Getting calcium from food is preferred; supplements help when intake is inadequate. Vitamin D matters for absorption, and exercise is essential for bone strength.
Can exercise really strengthen bone?
Yes. Weight-bearing and resistance exercise stimulate bone and, importantly, reduce falls — the immediate cause of most fractures.
