"Kombucha can be a great source of probiotics, and generally speaking, probiotics are helpful for fighting belly bloat," said Zeitlin. "Since this drink combines the gut-helpers with carbonation, it can backfire, as carbonation usually leads to feeling bloated and gassy. Additionally, kombucha can be acidic, so if you have any sort of reflux, this drink may make it worse." She suggested that you only drink half a bottle at time and space it out during the week instead of consuming it every day.
