The Science

The gut is one of the most complex organ systems in the body, with its own enteric nervous system, a vast immune surface, and a mucosal barrier that must simultaneously allow nutrient absorption and prevent pathogen entry. Peptides that support gut health work through several mechanisms: protecting and repairing the mucosal lining, modulating the gut-brain axis through vagal nerve pathways, reducing intestinal inflammation, and promoting the growth of beneficial gut flora. BPC-157 is uniquely positioned in this space due to its demonstrated ability to protect against NSAID-induced gastric damage, accelerate healing of inflammatory bowel disease, and modulate the gut-brain connection.
