GLP-1 is a peptide that has been shown to lower blood sugar levels and enhance insulin secretion. Research shows that GLP-1 may also improve heart, liver, and lung function while helping to slow or prevent the effects of Alzheimer’s disease. Research with GLP-1 has shown it can significantly decrease appetite by delaying gastric emptying and reducing intestinal motility. Glucagon-Like Peptide-1 (GLP-1) Analogs have been shown to stimulate insulin and suppress glucagon secretion in a glucose-dependent manner.
