## Summary

This review argues that general protein guidelines may not be enough for older adults trying to keep their muscle. Older bodies need more protein, spread evenly through the day, with a focus on leucine-rich foods like animal proteins. The authors note that creatine, vitamin D, collagen, and omega-3s, combined with resistance training, may further support muscle health.

## Practical Takeaway

This review suggests older adults may benefit from higher, evenly-distributed protein intake to help preserve muscle.
