bromelain improves digestion
In plain terms: Does bromelain aid digestion?
Part of: 🧪 bromelain
It's marketed as a digestive enzyme, but no human studies actually show it improves digestion — its evidenced effects are anti-inflammatory, not digestive.

How the studies fall
What the evidence shows
Marketed as a 'digestive enzyme,' but that's rationale, not evidence. Bromelain is a proteolytic enzyme and survives digestion partly intact, yet no human trials show it actually improves digestion or symptoms — its studied effects are anti-inflammatory/systemic, not digestive.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
