GLP-2 (Glucagon-Like Peptide-2) is a 33-amino acid peptide known for its powerful intestinotrophic effects. It promotes intestinal mucosal growth, enhances nutrient absorption, strengthens the gut barrier, and supports tissue repair in the digestive system. Researchers primarily study GLP-2 for conditions involving intestinal injury or malabsorption, such as short bowel syndrome and inflammatory bowel disease, due to its role in improving gut integrity and overall gastrointestinal function.
