Casein & Gluten Free Broad Spectrum Digestion Formulation with Dipeptidyl Peptidase IV Analog Enzyme Dietary Supplement Ultra Tested - Tested for More than 950 Contaminants! Heavy Metals Bacteria Yeast Mold Pesticides & More... EnZym-Complete/DPP-IV is Kirkman’s popular broad-spectrum digestive enzyme. This proprietary product is formulated to support maximum digestive activity for a full range of foods. EnZym-Complete/DPP-IV is a unique blend of 18 pure, plant-based enzymes that are recognized as essential for the effective digestion of all food groups, including proteins, carbohydrates, fats, sugars and fiber under a wide range of pH conditions. The addition of the dipeptidyl peptidase-IV (DPP-IV) enzyme analog supports the ability of the body to degrade peptides formed from exposure to casein and gluten. EnZym-Complete/DPP-IV provides a comprehensive "foundation" of supplemental enzymes to support optimal digestion. Each enzyme works independently, but also in a complementary role to optimally impact digestion of all dietary components. Kirkman’s EnZym-Complete/DPP-IV provides a combination of proteases, amylases, lipases, disaccharides and cellulases that replace the enzymes lost in cooking, thus lessening the burden on the body's digestive tract so that it can function optimally, while also supporting optimal nutrient absorption.
