NutriStack
Melatonin and Pantoprazole, a synergy.
Melatonin has gastroprotective effects and increases lower esophageal sphincter tone, and small randomized trials show additive GERD symptom relief when combined with a PPI. Patients with persistent reflux on pantoprazole sometimes benefit from adjunctive bedtime melatonin. The evidence is emerging but mechanistically plausible.

Synergy
What is happening. Melatonin has gastroprotective effects and increases lower esophageal sphincter tone, and small randomized trials show additive GERD symptom relief when combined with a PPI. Patients with persistent reflux on pantoprazole sometimes benefit from adjunctive bedtime melatonin. The evidence is emerging but mechanistically plausible.
Mechanism. Melatonin increases lower esophageal sphincter pressure, scavenges mucosal free radicals, and inhibits nitric oxide-mediated relaxation. These effects complement pantoprazole's irreversible inhibition of the gastric H+/K+-ATPase.
Recommendation. If you have ongoing reflux symptoms on pantoprazole, ask your prescriber about a trial of melatonin 3-6 mg at bedtime. Do not stop pantoprazole abruptly, since rebound acid hypersecretion is common.
