Brief Summary

This pilot study is designed as a monocentric, open label, interventional, parallel arms, controlled clinical trial. The aim of the study is to assess the gastrointestinal pH and motility after the consumption of milk. The clinical study is categorized as an interventional research involving the human person with low risks and constraints (RIPH 2) and which does not assess a health product. The milk and medical device used in this clinical study are both authorized and already commercialized in France.

You may not qualify if:

• Suffering from a metabolic disorder such as diabetes, uncontrolled thyroidal trouble, uncontrolled arterial hypertension or other metabolic disorder,
• Suffering from a severe chronic disease (e.g. cancer, HIV, renal failure, hepatic or biliary disorders ongoing, chronic inflammatory digestive disease, arthritis, etc.) or disorders found to be inconsistent with the conduct of the study by the investigator,
• Suffering from any obstructive or restrictive respiratory syndrome (COPD, asthma, etc.) that may impact breath test measurements,
• Suffering from a gastro-intestinal pathology (inflammatory bowel disease, Crohn disease, ulcerative colitis, irritable bowel syndrome, celiac disease, gluten hypersensitivity, small intestinal bacterial overgrowth, diverticulitis, polyps, constipation, esophageal motility abnormality, history of gastric bezoar...), or other gastro-intestinal disorders found to be inconsistent with the conduct of the study by the investigator,

• With a lactose intolerance diagnosed by a positive Lactose Breath Test,
• Pregnant or lactating women or intending to become pregnant during the study,
• Under treatment or dietary supplement which could significantly affect the gut motility and/or interfere with gastric emptying time and/or affect the gut pH during the study according to the investigator or stopped less than 15 days before the V0 visit (examples: NSAIDs, proton pump inhibitors, prokinetics, treatments against diarrhea or constipation, etc.),
• Regular intake of dietary supplements containing prebiotics, probiotics or symbiotics, or stopped less than 3 months before the V0 visit,
