Taking magnesium supplements leads to better sleep quality through changes in brain chemicals that control sleep.
People with lower levels of magnesium in their blood have a higher severity of obstructive sleep apnea, measured by the number of breathing interruptions per hour, especially when magnesium levels fall below 1.98 mg/dL.
In elderly individuals, low magnesium levels are linked to shorter deep sleep and weaker brainwave activity during deep sleep, and taking magnesium supplements increases deep sleep duration by 6.4 minutes per night.
Low magnesium levels are linked to higher levels of inflammation and oxidative stress markers, and these same markers are linked to poorer sleep quality.
In people with restless legs syndrome, especially pregnant women and those with mild to moderate symptoms, lower magnesium levels in the blood are linked to worse symptoms, and magnesium given intravenously has led to complete symptom relief in some isolated cases.
