Gastric Acid Suppression and Probiotic Colonization

Completed · Phase 4 · Has a placebo group

Conditions studied: Probiotics

In brief

Probiotics are over-the-counter dietary products with microorganisms that are generally consumed for health benefit. However, the durability of these microorganisms is unclear, particularly when they pass through the highly acidic environment of the stomach. We will test the colonization of these microorganisms among individuals who consume probiotics with and without acid suppression therapy.
