Bromelain
A protein-digesting enzyme extracted from pineapple stems — one of the better-researched natural enzymes, with genuine clinical data behind its digestive and anti-inflammatory effects.
Bromelain is a mixture of proteolytic (protein-digesting) enzymes extracted primarily from the stem of the pineapple plant (Ananas comosus), though smaller amounts are also present in the fruit itself. It has a long history of traditional use in Central and South America and has been studied in modern clinical research since the mid-20th century for its digestive and anti-inflammatory properties.
Unlike many botanical supplements with thin evidence bases, bromelain has a genuinely substantial body of clinical research behind several of its uses, particularly for digestive support, reducing inflammation and swelling, and supporting recovery after minor surgical or dental procedures. Potency is typically measured in enzyme activity units (GDU or MCU) rather than simple milligram weight, since enzyme activity — not just mass — determines effectiveness.
Bromelain is commonly included in digestive enzyme blends, as well as standalone anti-inflammatory and recovery-focused formulas.
Breaks Down Dietary Protein
As a proteolytic enzyme, bromelain helps cleave protein into smaller peptides and amino acids, supporting digestion when taken alongside meals — particularly protein-heavy ones.
Modulates Inflammatory Mediators
When absorbed systemically (typically when taken away from food), bromelain appears to influence inflammatory signaling pathways and may help break down fibrin, contributing to its studied effects on swelling and bruising.
Mild Effect on Platelet Aggregation
Bromelain has demonstrated mild antiplatelet activity in research, which contributes to both its anti-inflammatory profile and the bleeding-risk caution relevant to those on blood thinners.
Digestive Support
Bromelain is commonly included in digestive enzyme blends for its protein-digesting activity, with research supporting its use for general digestive comfort alongside meals, particularly higher-protein ones.
Take with meals for this specific use
Post-Procedure Swelling & Bruising
Several clinical studies, including research following dental extractions and minor surgical procedures, have found bromelain supplementation associated with reduced swelling and faster resolution of bruising compared to placebo.

Sinus & Respiratory Comfort
Some research has examined bromelain as an adjunct for sinusitis symptoms, with modest supporting evidence for reduced inflammation and improved symptom scores when combined with standard treatment.
Best used as a complement to, not replacement for, standard sinusitis treatment
Exercise Recovery Support
Bromelain's anti-inflammatory properties have led to its inclusion in some exercise recovery formulas, with the underlying mechanism similar to its post-procedure swelling research, though direct sports-specific trials are more limited.

| Use Case | Typical Dose | Notes |
|---|---|---|
| Digestive support | 500mg with meals | Taken with food so it can act on dietary protein. |
| Anti-inflammatory / systemic use | 500–2,000mg on an empty stomach | Taken away from meals to maximize systemic absorption. |
Timing
For digestive use, take with meals. For anti-inflammatory or recovery use, take on an empty stomach (30–60 minutes before eating, or 2+ hours after) so the enzyme is absorbed systemically rather than used up digesting food. Look for potency listed in GDU or MCU enzyme activity units, not just milligrams.
⚠️ Important Interactions & Cautions
- Blood thinners: Bromelain has mild antiplatelet activity and may increase bleeding risk when combined with anticoagulant or antiplatelet medications.
- Upcoming surgery: Discontinue at least 2 weeks before any scheduled surgery due to bleeding risk.
- Antibiotics: Some research suggests bromelain may enhance the absorption of certain antibiotics (like amoxicillin); discuss timing with your doctor or pharmacist if relevant.
- Pineapple or latex allergy: Those with known allergies to pineapple or latex should use caution, as cross-reactivity is possible.
- Pregnancy: Avoid — insufficient safety data, and some traditional concern about uterine effects at high doses.
✅ Generally Safe
- Long history of clinical research and traditional use
- Well-tolerated at standard doses
- No serious organ toxicity reported in clinical trials
Mild Side Effects
- GI upset, especially on an empty stomach
- Mild allergic reactions in sensitive individuals
- Diarrhea at high doses
