Official title

The Effect of Gastric Acid Suppression on Probiotic Colonization

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
