ZGlutn is a combination of concentrated enzymes and herbs designed to support the digestion of gluten and casein. ZGlutn should be called the "bad meal" corrector. This formula is designed to be taken 30-45 minutes prior to meals containing wheat and dairy. The other way to take this formula is to take it 2 hours after eating. The enzymes found in ZGlutn help the body break down and digest the protein found in wheat and dairy to minimize its negative effects on the digestive system.
