It is present in foods such as leafy green vegetables, legumes, nuts, seeds, and whole grains, and is also available as a dietary supplement in several different salt forms. Magnesium Science is an independent resource that catalogues peer-reviewed research on magnesium and describes what each study examined and reported, linking back to the original publications.
