Is carbonated water healthier?

There’s no evidence that carbonated water is better or worse for you than non-carbonated water. However, when some people consume carbonated water, their digestion is better.

That could be because:

• Carbonic acid could buffer the pH

• It acidifies the digestive system

Below a pH of 7, things are more acidic. Because the stomach has the lowest pH of any part of the body, carbonic acid – being a weak acid – might be better than regular water for some people.

Types of carbonated water:

• Seltzer water – no minerals, carbonated

• Club soda – minerals, carbonated

• Tonic water – quinine, carbonated
