Magnesium Carbonate

[1] Magnesium is a naturally occurring mineral, and is essential for the diet. It is important for many systems in the body, especially the muscles and nerves. Magnesium is present in fruits, vegetables, grains, milk, meat and fish and the natural content of these foods is the major source of the current dietary intake. Magnesium carbonate, often combined with aluminum hydroxide, is used as an antacid. Pure magnesium carbonate (MgCO3) is used in the pharmaceutical industry as a tablet and capsule diluent.[1]
