New York: 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, as “there is really sparse evidence that taking super-therapeutic doses of magnesium will give you a benefit,” said Dr. Raj Dasgupta, a professor of pulmonary and sleep medicine at the University of Southern California.
The mineral is widely available in both plant and animal-based foods, and the kidneys limit urinary excretion of magnesium, so deficiencies are rare in healthy people. Leafy green vegetables, nuts, legumes and whole grains are good sources of magnesium; fish, chicken and beef also contain magnesium. Older adults and people with certain disorders, such as Type 2 diabetes, gastrointestinal diseases and alcoholism, however, may have inadequate amounts.
