What is magnesium?
An introduction to magnesium, an essential dietary mineral, and how Magnesium Science catalogues the research.
Magnesium is an essential dietary mineral and one of the most abundant minerals in the human body, where it participates in many normal biochemical processes. 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. Nothing on this site is a substitute for personalized advice from a licensed healthcare provider.
