bromelain

A pineapple-derived enzyme whose one solid oral use is reducing swelling and pain after surgery (mostly dental trials, one as good as diclofenac). Beyond that the evidence thins out fast: the osteoarthritis data are mostly enzyme-combo products, sinusitis rests on a 1960s trial, and 'digestive enzyme' / anti-cancer claims are rationale or lab-only. Generally safe, but it's a mild blood-thinner and a pineapple-allergy risk. (The FDA burn-debridement drug NexoBrid is topical bromelain — not the oral supplement.)

The 7 claims about bromelain

Each keeps its own verdict — we never average them away.

Does bromelain reduce swelling after surgery?

Strong support Yes — this is its best-proven use. Trials (mostly after dental surgery) show oral bromelain cuts post-op swelling, pain and jaw-stiffness, in one study as well as the drug diclofenac. Small and mostly dental, but real.

Is bromelain safe to take?

Strong support Generally safe, with a few real caveats: it can trigger reactions if you're allergic to pineapple, it mildly thins the blood (care with blood thinners and around surgery), and it can increase absorption of some antibiotics.

Does bromelain fight cancer?

Leans support 🐭 Non-human evidence Lab-only. It slows cancer cells in a dish and in some animal studies, but there's no human evidence it prevents or treats cancer.

Does bromelain help arthritis and joint pain?

Insufficient Unproven on its own. The main positive knee-osteoarthritis trial used a bromelain-plus-other-enzymes blend, so you can't credit bromelain alone. Promising but not established.

Does bromelain help sinusitis?

Strong support The evidence is old and thin — a 1960s trial and a pediatric study suggested faster recovery, but that's not enough to establish it.

Does bromelain help muscle soreness and recovery?

Insufficient Barely tested. One small enzyme-blend trial hinted at less muscle damage after exercise — minimal, confounded evidence. Not established.

Does bromelain aid digestion?

Insufficient 🐭 Non-human evidence It's marketed as a digestive enzyme, but no human studies actually show it improves digestion — its evidenced effects are anti-inflammatory, not digestive.
