TrueDIGEST contains a combination of digestive enzymes. Digestive enzymes include pancreatic enzymes and fungus- or plant-derived enzymes. Enzymes help to break down foods, allowing for easier absorption and assimilation. Hydrochloric acid is naturally present in the stomach and is important for the process of digestion. These products should be included in your healthy digestion plan if you experience gas, bloating, fullness after eating, indigestion or occasional constipation. Heartburn or reflux is often caused when levels of hydrochloric acid are too low, not too high. We suggest you try an acid replacement to see if your symptoms improve.
