Magnesium is important for many processes in the body, including regulating muscle and nerve function, blood sugar levels, and blood pressure and making protein, bone, and DNA.
One study. View Source of older adults with insomnia found that magnesium supplementation at a dose of 500 milligrams daily for eight weeks helped them fall asleep fast, stay asleep longer, reduced nighttime awakenings, and increased their levels of naturally circulating melatonin.

Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation [1-3].
