Bromelain for Digestive Health

Research suggests that bromelain may have some relevance to digestive health, though the available evidence base is limited and mixed in its implications. The two studies identified include an animal study showing that bromelain supplementation improved bowel function recovery following surgery in rats, potentially by reducing inflammatory signaling in the colon, and a product quality analysis that found most commercial bromelain supplements contain largely inactive enzyme, raising questions about whether retail products deliver the active compound studied in research settings. These are preliminary study types — one animal model and one analytical framework study — neither of which constitutes clinical evidence in humans, and no randomized controlled trials or human clinical data were identified in this review. Overall, while the mechanistic basis for bromelain's digestive effects appears plausible, the combination of limited human research and documented quality control problems in commercial products means the evidence is too early-stage to draw firm conclusions about its practical effectiveness for digestive health.
