1. Enhanced digestion: Maximum Spectrum Enzym-Complete/DPP-IV™ Fruit Free w/Isogest® contains a potent blend of enzymes that helps break down proteins, fats, and carbohydrates, promoting optimal digestion and absorption of nutrients.
2. Reduce food sensitivities: This product features Isogest®, a proprietary blend of enzymes that specifically targets gluten and casein, two common allergens found in many foods. Regular use of this supplement may help reduce symptoms of food sensitivities and intolerances.

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

DPP-IV refers to a peptidase enzyme activity that contributes to the breakdown of specific peptide bonds in dietary proteins.

This form is provided within a broad-spectrum plant-based enzyme blend and is delivered in a gastric acid-resistant system to enhance survival through the stomach and reach the small intestine where digestion predominantly occurs.

What Does DPP-IV Do?

Studies show that DPP-IV enzymes may help break down casein and gluten-derived peptides, which can support digestion of these foods in line with EFSA and NHS guidance. This supports normal digestion and nutrient uptake, particularly when complex proteins are consumed.

The evidence is focused on mechanism and normal digestive function, and broader clinical outcomes require further research as noted in EFSA- and NHS-aligned discussions.

Dr. Matysiak-Budnik of University found that DPP-IV activity can contribute to processing peptide fragments from certain dietary proteins, highlighting its role within an enzyme blend.
