What lifestyle measures help prevent osteoporosis?

• A. Weight-bearing exercise.
• B. Calcium and vitamin D intake.
• C. Calcium and vitamin D intake, weight-bearing exercise.
• D. Calcium supplementation alone.

Answer: (C)

The main concept is that preventing osteoporosis relies on both getting enough bone-building nutrients and providing the mechanical stimulus that keeps bone strong. Calcium and vitamin D work together: calcium provides the mineral that bones are made of, and vitamin D helps the body absorb that calcium and use it for bone remodeling. Without sufficient vitamin D, calcium absorption drops, so bone support weakens even if you’re taking calcium. Weight-bearing exercise adds the necessary mechanical load on bones. Activities like walking, stair climbing, or resistance training stimulate bone formation and help maintain or increase bone density, while also improving balance to reduce fracture risk. Putting these together gives the most effective prevention: adequate calcium and vitamin D intake to supply the bone mineral and its proper utilization, plus regular weight-bearing exercise to strengthen the bones through use. If you rely on one element alone—exercise without adequate calcium/vitamin D, or calcium/vitamin D without the loading from activity—the protective effect on bone is weaker. Calcium supplementation alone misses the vitamin D support and the exercise stimulus, so it’s not as protective as the combined approach.
