GLP-2

Price and cost-per-mg comparison

GLP-2 (glucagon-like peptide-2) is a 33-amino-acid endogenous proglucagon-derived peptide secreted by intestinal L-cells in response to nutrient ingestion, functioning as a trophic and protective hormone for the intestinal epithelium with roles in mucosal growth, barrier integrity, and nutrient absorption. GLP-2 signals through a specific receptor (GLP-2R) expressed on intestinal subepithelial myofibroblasts and enteric neurons, promoting enterocyte proliferation while inhibiting apoptosis, reducing intestinal permeability, and modulating gut motility to collectively support intestinal adaptation and absorptive capacity. Clinical evidence for GLP-2 pathway activity is established through teduglutide (Gattex/Revestive), a DPP-IV-resistant GLP-2 analog approved by the FDA in 2012 for short bowel syndrome-associated intestinal failure; Phase 3 trials and long-term follow-up studies demonstrated significant reductions in parenteral nutrition requirements, validating GLP-2 receptor agonism as a viable therapeutic approach. Native GLP-2 itself is not used therapeutically due to a plasma half-life of approximately 7 minutes from rapid DPP-IV degradation; clinical application is exclusively through the stabilized analog teduglutide, which requires a prescription and is indicated specifically for short bowel syndrome — a rare gastrointestinal condition — rather than general wellness or off-label intestinal support.
