Studies have found a link between low levels of magnesium, an essential mineral that plays a crucial role in a wide range of bodily processes, and sleep disorders. But if you are concerned you aren’t getting enough magnesium, changing your diet may be a better option than taking a supplement,
Leafy green vegetables, nuts, legumes and whole grains are good sources of magnesium; fish, chicken and beef also contain magnesium.
If you suspect you’re deficient in magnesium or want to take magnesium supplements, talk to your doctor first. Magnesium can interact poorly with other drugs, and taking excessive amounts in the form of supplements can cause stomach cramps, diarrhea and nausea. Including more leafy green vegetables, legumes, nuts, seeds and whole grains in your diet may be a better option, doctors say.
