Black Pepper (Piperine) for Digestive Health

Research suggests that piperine, the primary active compound in black pepper, may support digestive health through several mechanisms, including stimulation of pancreatic digestive enzymes, antioxidant activity, and modulation of inflammatory pathways relevant to conditions like inflammatory bowel disease, based largely on laboratory and animal studies reviewed across multiple publications. Studies indicate that piperine has also been investigated at the preclinical level for its effects on gut microbiome composition and gastric cancer cell metabolism, with one 2025 study identifying it as a potentially meaningful anticancer agent in animal models, though these findings have not yet been confirmed in human trials. The body of evidence reviewed here consists primarily of narrative and systematic reviews of in vitro and animal research, with only limited clinical trial data directly examining piperine's digestive effects, and one included randomized controlled trial focused on a postbiotic supplement rather than piperine itself, making it only tangentially relevant. Overall, while the existing research is directionally supportive, the near-complete absence of robust human clinical trials means conclusions about piperine's digestive benefits in people remain preliminary, and further well-designed studies are needed before stronger claims can be made.
