Magnesium Is a Vital Ion in the Body—It Is Time to Consider Its Supplementation on a Routine Basis

The importance of maintaining proper magnesium intake and total body magnesium content in preserving human health remains underappreciated among medical professionals and laymen. This review aimed to show the importance of hypomagnesemia as a modifiable risk factor for developing disease processes. We searched the PubMed database and Google Scholar using the keywords ‘magnesium’, ‘diabetes’, ‘cardiovascular disease’, ‘respiratory disease’, ‘immune system’, ‘inflammation’, ‘autoimmune disease’, ‘neurology’, ‘psychiatry’, ‘cognitive function’, ‘cancer’, and ‘vascular calcification’. In multiple contexts of the search terms, all reviews, animal experiments, and human observational data indicated that magnesium deficiency can lead to or contribute to developing many disease states. The conclusions of several in-depth reviews support our working hypothesis that magnesium and its supplementation are often undervalued and underutilized. Although much research has confirmed the importance of proper magnesium supply and tissue levels, simple and inexpensive magnesium supplementation has not yet been sufficiently recognized or promoted.
