Papain is a proteolytic enzyme (a protease) from the papaya fruit. It is famous for its ability to break down proteins (hydrolysis) into smaller peptides and amino acids. It has been a commercial success in the industry for over 40 years.
Even the best papain product will yield poor results if applied incorrectly. Because papain acts aggressively on proteins, precise control is mandatory. | Feature | Plant Papain (Carica papaya) |
If you are looking for how papain can be made "better" (more stable), researchers focus on immobilization Papain vs. Bromelain - Specialty Enzymes & Probiotics™
Avoid this product if you have a known allergy to papaya or latex. Even the best papain product will yield poor
: Papain is better .
We cannot ignore economics. Papain is cheap. Papaya trees produce massive amounts of latex, and extraction is simple gravity filtration.
Take the capsule on an empty stomach, at least two hours after or one hour before eating.
