Study Summary

In this study the investigators will test a nutritional supplement called betaine hydrochloride to see if it can temporarily increase the stomach acid in healthy volunteers who have decreased stomach acid because they take a medicine called rabeprazole.

Primary Outcome

Gastric pH levels monitored with a Heidelberg pH capsule (HC) which sends real-time signals to a computer system that visually plots intestinal pH on a minute-by-minute basis. When subject's pH remained above 4.0 for at least 15 minutes, a 1500 mg dose of betaine HCl was given orally with 90 mL of water, and gastric pH was continuously monitored for 2 hours.

Interventions
