Mineral water is considered to be better than purified water in the taste category because it already comes with flavor-enhancing minerals. Mineral water usually comes from natural springs and has plenty of dissolved gases and minerals such as calcium carbonate, potassium, and sodium sulfate. One can also prepare it artificially by adding salts to distilled water or through aeration (bringing together air and water to take away undesirable substances). Some of the minerals and their biological functions found in mineral water include calcium for bone development and muscle regulation, chlorine for hydrochloric acid formation, phosphorus for protein synthesis, magnesium for bone formation, and potassium for muscle and myocardial activities.
