The Claim

In a simulated human colon system (SHIME®), supplementation with 2.6 g/day of pomegranate extract for one week is associated with decreased abundance of Prevotella in the ascending and transverse colon and reduced propionate production in the transverse colon.

In plain English

When pomegranate extract is added to a lab model of the human colon, the abundance of Prevotella bacteria decreases in the ascending and transverse colon, and propionate production decreases in the transverse colon.

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 decreased abundance of Prevotella in the ascending and transverse colon, potentially linked to reduced propionate production in the transverse colon.

Why this might work

Pomegranate compounds break down in the colon into molecules that kill or slow down certain bacteria called Prevotella. Fewer Prevotella bacteria mean less propionate acid is made in the middle part of the colon.

  1. Study: Gut Microbiota Modulation by Pomegranate Extract: Insights from a Controlled Supplementation Study

    In a lab model of the human colon, taking pomegranate extract for a week lowered a type of gut bacteria called Prevotella, and this drop was linked to less of a healthy acid (propionate) being made in that part of the colon.
