What ingredient in purified drinking water makes you gassy?

There is no specific ingredient in purified drinking water that would make you gassy. Gassiness is typically caused by the presence of gas-producing bacteria in the digestive system or by consuming certain foods or drinks that can lead to excess gas production. If you are experiencing gassiness after drinking purified water, it is likely unrelated to the water itself.

Purified drinking water does not contain any ingredients that cause gas.
