ZymeMax is a digestive enzyme supplement with hydrochloric acid, pepsin and other natural ingredients to help maintain a healthy intestinal lining. 10 plant-based enzymes help digest a variety of foods (including proteins, carbohydrates and fats) and assist with nutrient absorption. Hydrochloric acid and pepsin work together in the stomach to help ensure complete protein digestion. Taken with meals, hydrochloric acid may also help relieve occasional heartburn. L-glutamine, N-acetyl- glucosamine and butyric acid are added to support the intestinal lining.
