Bone is a living tissue

Old bone is broken down and new bone is built every day. The balance shifts with hormones, nutrition, and activity.

Protect your bones

  • Resistance training twice a week — bone responds to load.
  • Adequate calcium (≈1000–1200 mg/day) and vitamin D.
  • Don't smoke. Keep alcohol moderate.
  • Consider DEXA screening from age 50, earlier if you have risk factors.
