What science says about Apple Cider Vinegar For GERD | Acid Reflux

Apple cider vinegar (ACV) has gained traction as a potential remedy for gastroesophageal reflux disease (GERD), or acid reflux. The theory is that low stomach acid contributes to reflux symptoms, and the acetic acid in ACV may help restore optimal acidity and improve lower esophageal sphincter (LES) function. Supporters believe this can enhance digestion and reduce symptoms, while skeptics highlight the lack of clinical evidence and potential risks. This review examines both perspectives on apple cider vinegar for GERD (acid reflux) based on available research findings, clinical reports, and expert commentary.

Support Views on Apple Cider Vinegar for GERD

Supporters argue that ACV might benefit GERD in cases where low stomach acid is the underlying cause. They suggest that acetic acid can help restore stomach acidity and improve LES closure, potentially preventing reflux. Some also point to its antimicrobial and prebiotic effects as beneficial for digestion.

In the review "Effectiveness of Nutritional Ingredients on Upper Gastrointestinal Conditions and Symptoms: A Narrative Review" (MDPI), ACV was mentioned as one of the ingredients tested in a chewing gum formula. However, it was combined with multiple other ingredients, making it impossible to isolate its effects.

One study titled "Effect of apple cider vinegar on delayed gastric emptying in patients with type 1 diabetes mellitus: a pilot study" focused on 10 patients with diabetic gastroparesis. Rather than showing benefit, it found that ACV significantly delayed gastric emptying, which could potentially worsen symptoms like bloating and reflux in some individuals.

Despite the lack of definitive evidence, anecdotal reports and online testimonials continue to promote ACV for heartburn relief, typically in diluted form.

Skeptic Views on Apple Cider Vinegar for GERD

Skeptics argue that there is no substantial clinical support for using ACV to manage GERD. The only clinical mention in a published review involved its use as one component in a multi-ingredient gum, which cannot support any isolated benefit for ACV.

Furthermore, a widely referenced Harvard Health article by Dr. Marcelo Campos notes that while some people claim ACV helps their reflux, there is no credible scientific evidence backing this. He also warns that due to its high acidity, ACV can irritate the esophagus, worsen symptoms, and damage tooth enamel if taken undiluted.

The same MDPI review also emphasizes that better-studied nutritional options for reflux exist, including alginate, melatonin, ginger, and peppermint-caraway oil combinations. These ingredients have stronger evidence for symptom relief and fewer associated risks.

Conclusion: What Science Says About Apple Cider Vinegar for GERD

In conclusion, apple cider vinegar is not supported by strong clinical evidence as a treatment for GERD. Only one small trial and one narrative review provide indirect mentions, with inconclusive or non-specific outcomes. The biological rationale for ACV aiding reflux is speculative and applicable only to certain cases where low stomach acid is a factor.

Meanwhile, ACV also carries notable risks, particularly esophageal irritation and enamel erosion, especially when consumed undiluted. Until larger, high-quality studies are available, ACV should not be considered a reliable or safe alternative to proven GERD therapies.

For those still interested in trying it, it must be used with caution, thoroughly diluted and monitored closely. However, better-supported options like ginger, alginate, and peppermint, caraway oil are more appropriate for symptom relief and long-term digestive support.
