GLP-1 Formula to boost GLP-1 and improve blood sugar control

Exploring the Effects of GLP-1 Formula on GLP-1 Secretion and Postprandial Glucose Regulation

NA · Chung Shan Medical University · NCT07082062

This will test whether a multi-ingredient GLP-1 dietary supplement can raise GLP-1 levels and improve blood sugar and insulin responses in adults with higher body fat.

What this trial studies

This randomized, crossover investigation tests a multi-component oral GLP-1 Formula containing a probiotic (Bifidobacterium breve), a prebiotic blend (including kombucha extract, soy peptide, L‑arabinose, erythritol), and rocket apple extract for effects on incretin and glycemic responses. The study is split into two parallel crossover trials of about 50 participants each: one measuring acute changes in circulating GLP-1 after a single dose and the other measuring postprandial glucose and insulin responses. Participants attend two intervention visits per trial with at least a one-month washout if enrolled in both trials; each visit involves fasting and serial post-meal blood sampling over roughly six hours and appetite assessments. The trial enrolls healthy adults 18–50 years with body fat >25% and excludes people with diabetes, major GI disorders, recent probiotic or weight-loss supplement use, pregnancy, or prior GI surgery.

Who should consider this trial

Good fit: Adults 18–50 years old with body fat percentage over 25% who are not pregnant or breastfeeding and have no diabetes, major gastrointestinal disease, recent probiotic or weight-loss product use, or prior gastrointestinal surgery.

Not a fit: People with diabetes, autoimmune disease, chronic gastrointestinal disorders, prior gastrointestinal surgery, lactose intolerance, recent use of probiotics or weight-loss products, or who are pregnant or breastfeeding are excluded and unlikely to receive benefit from joining this trial.

Why it matters

Potential benefit: If successful, the formula could increase endogenous GLP-1 secretion and improve post-meal glucose and insulin control, potentially supporting metabolic health in overweight adults.

How similar studies have performed: Some prior studies of specific probiotics or prebiotics have shown modest effects on incretin hormones and postprandial glucose, but this exact multi-component GLP-1 Formula is novel and not widely tested in humans.
