# Higher Magnesium Intake Linked to Less Muscle Loss After 50

*Associations of magnesium intake and a magnesium-rich diet score with sarcopenia in middle-aged and older Korean adults: potential mediation by C-reactive protein.*

## Summary

Among Korean adults over 50, those eating the most magnesium had roughly half the odds of sarcopenia (age-related muscle loss) compared to those eating the least. The same held for a diet score built around magnesium-rich foods like whole grains, nuts, legumes, leafy greens and coffee. Lower inflammation explained a small slice of the link. This was a snapshot in time, so it cannot prove magnesium causes stronger muscles.

## Practical Takeaway

This study suggests magnesium-rich foods may be associated with better muscle preservation in older adults.
