- vs. bromelain: Both are plant-derived protease enzymes. Papain is from papaya, bromelain is from pineapple - both break down proteins similarly.
- vs. protease: Papain is a specific plant-based protease from papaya, while protease is a general term for any protein-digesting enzyme.
- vs. lipase: Papain is a protease enzyme breaking down proteins, while lipase is an enzyme breaking down fats - different substrates.
Why It's Used in Dog Products
Manufacturers include papain in dog food, treats, and supplements for several reasons:
- Aids protein digestion and breakdown
- Supports digestive health
- May reduce bloating and gas
- Helps dogs with protein malabsorption
- Natural alternative to animal-derived digestive enzymes

Effective plant-based protein-digesting enzyme. Quality depends on activity units (PU - Papain Units). Works in a wider pH range than some digestive enzymes. Often combined with other enzymes for comprehensive digestive support. Derived from unripe papaya fruit.
Potential Concerns
While papain can be appropriate in dog nutrition, pet owners should be aware of efficacy, quality of source material, and potential interactions with medications. Individual dogs may respond differently to the same ingredient based on their health status, age, and sensitivities.
Reliable digestive enzyme particularly useful for protein-heavy diets. Plant-based and works effectively across different pH levels in the digestive tract. Look for products with stated activity units for quality assurance.
