Is sparkling water as good as normal water? can i drink more sparkling than regular water?

Same: Sparkling water is simply carbonated water. It should have the same properties as regular water but you may notice more bloating or gas with it as it is carbonated like soda.

Filtered water: sparkling water indicates carbon dioxide dissolved in the water. Drinking this requires the body to neutralize the acidity as pH balance is tightly controlled. One 12 oz serving requires several liters of plain water or calcium from bone to neutralize. This increases risk for osteoporosis. Ideal water is spring water from a "clean" source, or reverse osmosis water to remove metals and toxins.

Sparkling: water has GAS ......usually Carbon Dioxide.... and glass for glass is just the same as regular water! BUT many people cannot tolerate the increased BOWEL GAS! Hope this is helpful Dr Z
