Bromelain
Best-in-class: Bromelain
A pineapple-derived proteolytic enzyme for protein digestion (with food) and anti-inflammatory/recovery support (empty stomach).
How Bromelain actually works
Bromelain is a mixture of cysteine proteases from the pineapple stem, and what it does depends entirely on when you take it. With food it acts in the gut lumen as a digestive enzyme, cleaving proteins into peptides. On an empty stomach a meaningful fraction is absorbed intact and acts systemically, where it interferes with fibrin and bradykinin and modulates inflammatory signalling. The systemic route is the basis for the swelling and bruising use, and it's also why absorption isn't a settled question — proteins usually aren't absorbed whole.
Bromelain quick facts
| Suggested dose | 500 mg (2,400 GDU) as directed; timing depends on goal. |
| How often | Daily during recovery; per meal for digestion |
| Who it's for | Digestion, sinus, inflammation and recovery. |
| Best-in-class brand | Bromelain |
✅ Clinically validated
- RCTs support reduced swelling/pain (sinusitis, post-surgery, osteoarthritis) and improved protein digestion.
- Anti-inflammatory and mucolytic activity.
📊 Correlative data
- Pineapple stem has traditional use across Central and South America for digestion and inflammation, and bromelain entered European clinical practice for post-surgical swelling on that basis. Occupational data in pineapple workers also documents the sensitisation risk.
🧪 Theoretical / extrapolated benefits
- Dual role: digestion WITH meals, anti-inflammatory BETWEEN meals.
These tiers tell you how much human evidence exists — not how well something works. This is the research space, and most of what’s in here is new rather than disproven. Something sitting at “theoretical” usually means nobody has funded the trial, not that the trial was run and failed.
The trap runs the other way too: something can be clinically validated and still do very little for you specifically. A statistically significant result in a study population is not a promise about your body.
- ✅ Clinically validated — human randomised trials or meta-analyses support it. The strongest footing available.
- 📊 Correlative — observational or epidemiological data. Suggestive, and genuinely useful for direction, but it cannot establish cause.
- 🧪 Theoretical / mechanistic — the mechanism is understood and often demonstrated in cells or animals, and the human trial doesn’t exist yet. Unproven is not the same as ineffective. Plenty of what’s standard practice today sat here five years ago.
✗ is a safety flag, not a grade. Where you see it, the concern is harm — not a disappointing trial. A compound tested for one purpose and found not to help there can still be worth studying somewhere else, so a negative result never gets rendered as a cross. It sits alongside the tier, because something can be both well-studied and genuinely risky.
My job is to tell you which one you’re looking at, and let you make the call. Grading something low isn’t me dismissing it — it’s me refusing to oversell it. This is the research space, and being able to reason forward from a mechanism matters as much as waiting for the trial.
The timing rule is the whole thing, and most people get it wrong: with a meal for digestion, well away from food for swelling and recovery. The best evidence is post-surgical and post-injury swelling, particularly dental and sinus work, which is a narrower claim than the general anti-inflammatory framing it's usually sold under. It has mild antiplatelet activity, so it's worth pausing before surgery and being careful alongside blood thinners. Pineapple allergy or latex allergy is a straightforward reason to skip it.
Bromelain — safety & side effects
- GI upset and diarrhoea. Allergy in people sensitive to pineapple, latex, wheat, celery or papain.
- Antiplatelet activity — Additive bleeding risk with anticoagulants and antiplatelets — warfarin, apixaban, rivaroxaban, clopidogrel, and aspirin at any dose. The interaction is pharmacodynamic rather than metabolic, so it does not show up as a changed drug level; it shows up as bruising, nosebleeds or a raised INR. Stop at least two weeks before any surgery or dental extraction. Surgeons ask about prescription blood thinners and rarely about supplements, so this one is on you to volunteer.
- Increases absorption of some antibiotics (amoxicillin, tetracycline), raising their levels. Menstrual bleeding may increase.
