4. May Help Reduce Inflammation
Low magnesium intake has been associated with increased inflammation, which is linked to aging and several chronic diseases.
Some studies found that magnesium supplementation helped reduce levels of C-reactive protein, often called CRP, which is a marker tied to inflammation in the body. Other research has suggested magnesium may also help lower additional inflammatory markers.
Researchers have also linked magnesium deficiency to oxidative stress, another process associated with inflammation and cellular damage.

Migraines can cause nausea, vomiting, and sensitivity to light and sound, and some researchers believe people who experience migraines may be more likely to have low magnesium levels.
