Could a simple magnesium supplement improve sleep?
The USDA's Agricultural Research Service says it might:

"Can't sleep? You are not alone. Not being able to sleep, or insomnia, is a common complaint, especially among people older than 50. More than half of all people aged 65 years and older have sleep problems."

"Not surprisingly, lack of sleep is caused mainly by factors that are more common later in life, such as breathing problems, illness and medications. Yet, scientists have proved that poor sleep is not a natural part of aging."

"A factor getting more attention recently is poor nutrition. A low intake of the mineral magnesium may be one nutritional factor causing sleep problems.  A low intake of the mineral magnesium may be one nutritional factor causing sleep problems."

"Magnesium plays a key role in the body's chemistry that regulates sleep. This may be why persons with long-term lack of sleep, or abnormal brain waves during deep sleep, often have low magnesium in their blood."

"Magnesium treatment increased deep sleep and improved brain waves during sleep in 12 elderly subjects. Magnesium treatment decreased time to fall asleep and improved sleep quality of 11 alcoholic patients who often have a low magnesium status. Magnesium deficiency increased time awake at the expense of deep sleep in rats. Feeding magnesium to the rats restored their sleep patterns to normal." (I wish they had provided references.)

"A national food consumption survey found that many Americans, especially older women, consume less than the RDA for magnesium."

"Another risk factor for low magnesium status in older women is the use of calcium supplements without magnesium for bone health. High calcium intakes can make magnesium deficiency worse."

Here's some good advice from Livestrong:

"It's nearly impossible to overdose on magnesium from diet alone. The possibility of a magnesium overdose increases when you take magnesium supplements. If you're unsure of your magnesium levels, talk to your health care provider and ask your doctor to check them for you. Until your appointment or test results come back, you can include magnesium-rich foods in your diet such as nuts, whole wheat flour, oatmeal, bananas and shredded wheat."
