GLP-1 (Glucagon-Like Peptide-1) is a naturally occurring incretin hormone produced in the intestinal L-cells in response to food intake. It plays a key role in regulating glucose metabolism and appetite signaling by interacting with GLP-1 receptors throughout the body, including in the pancreas and central nervous system.

Preclinical and clinical research suggests that GLP-1 supports glucose-dependent insulin secretion, slows gastric emptying, and influences satiety signaling pathways in the brain. These mechanisms are believed to contribute to its observed effects in studies examining glycemic balance, energy regulation, and metabolic homeostasis. Because its activity is glucose-dependent, GLP-1 signaling is closely tied to post-meal metabolic responses.

Beyond its role in glucose regulation, GLP-1 has also been investigated for its potential influence on cardiovascular signaling, inflammatory balance, and broader metabolic adaptation pathways. Ongoing research continues to evaluate its impact on endocrine regulation, appetite control, and systemic metabolic function.
