Magnesite (magnesium carbonate) is a non-toxic mineral. Magnesium carbonate is an effective phosphate binder for chronic hemodialysis patients. It prevents vascular calcification in these patients. Many patients with heavily symptomatic Mitral valve prolapse syndrome have low serum magnesium, and supplementation of this ion by means of magnesium carbonate leads to improvement in most symptoms.
