The Active Ingredient Is: DPP-IV (Dipeptidyl peptidase-IV) Enzyme

DPP-IV, or dipeptidyl peptidase-IV, is a digestive enzyme that participates in the breakdown of peptides within the gastrointestinal tract. This active enzyme is incorporated as part of a broad enzyme blend to support protein and peptide digestion.

This form is part of a multi-enzyme formulation designed to enhance overall digestive efficiency, with the DPP-IV component contributing to the processing of proline-rich peptides found in gluten and casein.

What Does DPP-IV Do?

DPP-IV helps maintain normal digestion by cleaving proline-rich peptides, aiding their breakdown in the gut. This mechanism supports digestive function in line with EFSA and NHS guidance on enzyme activity in digestion.

Dr. Püspök of a European university found that such enzymes can degrade gluten- and casein-derived peptides, which may influence gut comfort in some individuals.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
