Magnesium and Asthma - Clinical Trials

Asthma currently affects an estimated 15 million Americans. A number of studies have found an association between low dietary magnesium (Mg) intake and increased asthma incidence and severity of symptoms. However, clinical intervention trials are necessary to directly assess whether there is a true protective or preventative causal relationship between low Mg and asthma. In our study, we will assess the effects of 6 1/2 months of oral Mg supplements or placebo on clinical markers of asthma control, indirect biomarkers of inflammation, bronchial hyperresponsiveness, and indices of oxidative defense and damage in subjects with mild to moderate persistent asthma.
