Kombucha belongs to the family of fermented drinks that scientists studying the gut microbiome have been interested in for years.
Live cultures and the microbiome
Unpasteurized kombucha contains live lactic-acid bacteria and yeast. Fermented foods are studied for their effect on the diversity of the gut microbiome, but the effects depend on many factors and vary from person to person.
What does science say?
Research on kombucha is still a developing field. Many observations come from lab or animal studies, and evidence from large human studies is so far more limited. That is why kombucha should not be treated as a medicine or a substitute for a varied diet.
How to introduce kombucha?
If you care about live cultures, choose unpasteurized kombucha and introduce it gradually – from about 100–150 ml a day. Watch how your body responds and drink it as part of a varied diet, not its foundation.
