Studies have linked magnesium deficiency with asthma, and there is evidence that supplements can help treat this disorder as well.

In one study, researchers enrolled 52 men and women, ages 21 to 55, who were suffering from mild to moderate asthma.

They were divided into two groups: one took 340 mg of magnesium daily and the other a placebo for 6 ½ months. They were then examined for asthma symptoms, along with lung responsiveness, pulmonary function, inflammation, and inflammation markers.

The researchers found that those who took magnesium experienced significant improvement in lung activity and function, as well as improvements in asthma control.

The study, published in the Journal of Asthma, adds to the evidence that taking magnesium is helpful for people with this condition.
