The Claim
In a simulated human colon system (SHIME®), supplementation with 2.6 g/day of pomegranate extract for one week increased the abundance of Mitsuokella in the transverse and descending colon, while 1.3 g/day decreased its abundance in the descending colon.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In a lab model of the human colon, a higher dose of pomegranate extract increased the levels of a specific gut bacterium called Mitsuokella in two colon regions, while a lower dose reduced it in one region.
See the scientific wording
In a simulated human colon system (SHIME®), supplementation with 2.6 g/day of pomegranate extract for one week was associated with increased abundance of Mitsuokella in the transverse and descending colon, contrasting with its decrease at 1.3 g/day in the descending colon, suggesting a dose-dependent and site-specific microbial response.
Pomegranate compounds break down in the colon into smaller molecules that feed some bacteria and block others. At higher doses, these molecules create conditions that let Mitsuokella grow more, especially in the middle and lower parts of the colon. At lower doses, the same molecules suppress Mitsuokella in the lower colon, likely because the concentration is too low to support it or because other bacteria outcompete it.

1 studyStudy: Gut Microbiota Modulation by Pomegranate Extract: Insights from a Controlled Supplementation Study
In a lab model of the colon, a higher dose of pomegranate extract made a certain gut bacteria called Mitsuokella grow more, while a lower dose made it shrink — and this only happened in certain parts of the colon, showing that both how much you take and where in the colon matter.
