Its hydrochloric acid content improves digestion in the stomach. Its bile content emulsifies fats so that lipase enzymes can go to work on them. Hydrochloric acid and bile also destroy gastrointestinal parasites. ULTRAGEST assures that the body makes the most productive use of its own enzymes. The enzymes in ULTRAGEST add to the body's own enzymes rather than substitute for them. This product does not create dependence. It makes up the difference between what the body is able to produce itself and what it needs for optimal digestion.
