How Does Magnesium Carbonate Affect the Body? - Healthy Directions
What is Magnesium Carbonate? Magnesium carbonate is a compound. The formula for the composition of magnesium carbonate is MgCO3. This means it has one molecule of the chemical elements magnesium bonded to three molecules of carbonate. Carbonate is a salt of carbonic acid. Carbonic acid occurs when carbon dioxide (CO2) is dissolved in water.
