NOW Foods Gluten Digest provides a specialized enzyme blend specifically formulated to help break down gluten — the difficult-to-digest protein complex in wheat, barley, and rye — before it can trigger symptoms in gluten-sensitive individuals. The formula features DPP-IV (dipeptidyl peptidase IV), the specific enzyme that cleaves proline-rich peptides in gluten that are responsible for most of the immune and digestive reactions, alongside a broader enzyme blend including protease and amylase. Gluten Digest is intended as a supplement for those with mild gluten sensitivity — not celiac disease — to support comfortable digestion when inadvertent gluten exposure occurs (cross-contamination, restaurant meals). It is not a substitute for a gluten-free diet in celiac patients. NOW Foods manufactures in their GMP-certified facility with activity-unit testing for all enzyme components.
