If you drink enzymes, it is normal to have bad odor and exhaust. 1. Enzymes will increase the probiotics in the intestinal tract, which will fight against harmful bacteria in the intestinal tract, such as E. coli and Enterococcus faecalis, to balance the normal flora in the intestinal tract. 2. At this time, a large amount of ammonia will be produced, and the release of ammonia will lead to odor and stinky exhaust. 2. Enzymes will play the role of lubricating the intestines, expanding the intestines and enhancing peristalsis. When the peristalsis is enhanced, drinking enzymes will lead to more exhaust, and the emission of ammonia in the exhaust will also cause the exhaust to have a bad smell. Therefore, it is normal to have a large amount of exhaust after drinking enzymes, and the exhaust has a bad smell or odor.
