## Summary

Vitamin C does more than fight colds. It's needed to build collagen, the scaffolding in your bones, tendons and muscle, and it helps manage oxidative stress. This review pulls together lab, animal and human work on vitamin C in osteoporosis, arthritis and muscle loss. The honest verdict: the mechanisms look solid, but good human trials are still thin on the ground.

## Practical Takeaway

This review suggests vitamin C supports bone and muscle tissue, though human proof is still limited.
