What is the usual fate of orally ingested enzyme supplements? ​

Quizplus · Accepted Answer

Enzymes are typically digested by gastrointestinal proteases before they can be absorbed and enter circulation. This is because enzymes are proteins, and the digestive system is designed to break down dietary proteins into their component amino acids. Some plant-based enzymes may be more resistant to digestion and may survive in the small intestine to a greater extent, but most are likely to be broken down before they can exert their intended effects.
