Systemic Enzymes (Bromelain/Trypsin/Rutin)

Systemic enzymes combine bromelain from pineapple, the digestive enzyme trypsin, and the plant compound rutin, and people use them for their effects on inflammation and swelling. Most look at them for knee osteoarthritis, where the evidence is strong: a pooled analysis of six trials found pain and joint function improved about as much as with the anti-inflammatory drug diclofenac. Evidence for sports injuries and swelling after surgery is only moderate, and the knee findings come from this specific combination.

Osteoarthritis (OA)

Osteoarthritis (OA): outcomes studied for Systemic Enzymes (Bromelain/Trypsin/Rutin)

Knee Osteoarthritis Pain (vs NSAID)

Individual patient-level meta-analysis (6 RCTs, n=697, 2016): OEC (bromelain/trypsin/rutoside) showed equivalent efficacy to diclofenac for Lequesne Algofunctional Index improvement. RCT (n=150, 12 weeks): Wobenzym comparable to diclofenac; both superior to placebo (P<0.05).

Improves (the measure goes down)Moderate effect
Joint Function in Osteoarthritis

Pooled analysis (6 RCTs): Significant improvement in joint function comparable to diclofenac. Narrative review (9 RCTs): OEC consistently improved Lequesne scores. Reduces reliance on rescue analgesic medication.

Improves (the measure goes up)Moderate effect
Safety vs NSAIDs

RCT (n=150): Adverse events similar to placebo (7.2% vs 9.1%) and lower than diclofenac (15.6%). Meta-analysis: Better GI safety profile than NSAIDs. Appropriate for long-term use in patients who cannot tolerate NSAIDs.

Athletic Injury Recovery

Double-blind RCT (ankle sprains): Proteolytic enzymes accelerated recovery vs placebo. Multiple studies show reduced swelling and faster return to function in soft tissue injuries. Historical use in sports medicine since 1960s.

Improves (the measure goes up)Moderate effect
Muscle Soreness (DOMS)

RCT (downhill running): Protease supplementation attenuated DOMS and improved muscle function recovery after eccentric exercise. Another study (21 days supplementation): Improved muscle function after 45-min downhill protocol.

Improves (the measure goes up)Small effect

Post-Surgical Swelling

Multiple studies in oral surgery and orthopedic procedures: Proteolytic enzymes reduced post-operative edema and inflammation. Used as adjunct therapy for faster surgical recovery.
