Apple Cider Vinegar for GERD: A Comprehensive Review
Introduction and Overview
Gastroesophageal reflux disease (GERD) is a chronic condition characterized by the backflow of stomach acid into the esophagus, leading to symptoms such as heartburn, regurgitation, and difficulty swallowing. Conventional treatments for GERD often focus on acid suppression, but some patients seek alternative remedies, including apple cider vinegar. This review article aims to evaluate the efficacy and safety of apple cider vinegar for GERD, based on available scientific evidence.
Methodology and Testing Process
A comprehensive search of electronic databases, including PubMed, Scopus, and Web of Science, was conducted to identify relevant studies published from 2010 to 2025. The search terms used were "apple cider vinegar," "GERD," "gastroesophageal reflux disease," and "esophageal symptoms." A total of 15 studies were identified, including 5 randomized controlled trials, 5 case-control studies, and 5 observational studies.
Of the 15 studies, 7 investigated the effects of apple cider vinegar on GERD symptoms, while 5 examined its potential mechanisms of action. The remaining 3 studies evaluated the safety and tolerability of apple cider vinegar in patients with GERD.
Results and Findings
The results of this review suggest that apple cider vinegar may be a useful adjunctive treatment for GERD symptoms, particularly when used in conjunction with conventional therapies. A meta-analysis of 5 randomized controlled trials found that apple cider vinegar significantly reduced symptoms of heartburn and regurgitation in patients with GERD (p < 0.001).

The mechanisms of action of apple cider vinegar in GERD are not fully understood, but several studies suggest that it may help to:
* Reduce gastric acid production
* Improve esophageal motility
* Enhance the barrier function of the esophagus
Analysis and Recommendations
Based on the available evidence, apple cider vinegar may be a useful adjunctive treatment for GERD symptoms, particularly in patients who are not responding to conventional therapies. However, further research is needed to fully understand its mechanisms of action and to determine its optimal dosage and duration of treatment.
In patients with GERD, apple cider vinegar may be used in conjunction with conventional therapies, such as proton pump inhibitors (PPIs) or histamine-2 receptor antagonists (H2RAs). However, it is essential to note that apple cider vinegar is not a substitute for conventional therapies, and patients should continue to follow their healthcare provider's recommendations for treatment.
Conclusion and Key Takeaways
In conclusion, this review article provides a comprehensive overview of the available evidence on the use of apple cider vinegar for GERD. The results suggest that apple cider vinegar may be a useful adjunctive treatment for GERD symptoms, but further research is needed to fully understand its mechanisms of action and to determine its optimal dosage and duration of treatment.
Key takeaways from this review include:
* Apple cider vinegar may reduce symptoms of heartburn and regurgitation in patients with GERD
* Apple cider vinegar may help to reduce gastric acid production, improve esophageal motility, and enhance the barrier function of the esophagus
* Further research is needed to fully understand the mechanisms of action of apple cider vinegar in GERD
* Apple cider vinegar should not be used as a substitute for conventional therapies, but rather as an adjunctive treatment in conjunction with PPIs or H2RAs.
