Is Kombucha Good for You? The fermented tea is full of healthy compounds, but the research on its benefits is limited. By Alice Callahan Aug. 26, 2025 Q: Iβve heard that drinking kombucha is good for the gut and for metabolic health. Is that true? Gabriela Fraiz, a doctoral student in Brazil, said she has noticed improvements in her gut health since she started drinking a little kombucha with her lunch. Sheβs less bloated and gassy, she said, and sheβs been more regular. She also loves the βfizzy, slightly citrusy and sweetβ taste of the fermented tea, which she brews herself. On social media, posts about kombuchaβs health benefits go much further, with some claiming the drink can help you lose weight, manage Type 2 diabetes and lower the risk of heart disease and cancer. While some limited evidence hints at certain benefits, most claims about kombucha on social media arenβt backed by human research, said Ms. Fraiz, who has studied the tea during her work on her Ph.D. in nutriti...
