Bromelain: The Pineapple Enzyme Beyond Digestion

Bromelain is a mixture of proteolytic (protein-digesting) enzymes extracted from pineapple stems. While it does aid protein digestion when taken with meals, its more interesting applications are systemic — taken on an empty stomach, it's absorbed intact and has been researched for anti-inflammatory, anti-edema, and immune-modulating effects.

Anti-Inflammatory Research

Bromelain has been studied for post-surgical swelling, sinusitis, sports injuries, and osteoarthritis. Its mechanism appears to involve modulation of prostaglandin synthesis, reduction of bradykinin levels, and effects on immune cell adhesion molecules. In Germany, bromelain is an approved post-surgical anti-inflammatory supplement.

Comparison with Papain

Bromelain and papain are both plant-derived proteolytic enzymes, but they differ in pH optima, specificity, and clinical applications. Bromelain is more extensively researched for systemic anti-inflammatory effects, while papain has a longer history of use in meat tenderizing and topical wound care.

Both belong to the broader category of proteolytic enzymes used for systemic purposes beyond digestion.
