Active Ingredient Description

Pancreatin when reaching the small intestine disintegrates (at pH>5.5) to release enzymes with lipolytic, amylolytic and proteolytic activity to ensure the digestion of fats, starches and proteins. The products of pancreatic digestion are then either absorbed directly, or following further hydrolysis by intestinal enzymes.


Protease is an trypsin that catalyzes (increases the rate of) proteolysis, the breakdown of proteins into smaller polypeptides or single amino acids. They do this by cleaving the peptide bonds within proteins by hydrolysis, a reaction where water breaks bonds.


Serrapeptase suppresses fibrinolytic activity and increased vascular permeability, suppresses edema of inflammation, strongly hydrolyzes bradykinin and cleaves fibrin and fibrinogen without affecting proteins.
