Fact Check: Is DGL good for acid reflux?

Is DGL Good for Acid Reflux?

Introduction

The claim that deglycyrrhizinated licorice (DGL) is beneficial for acid reflux has garnered attention in various health discussions. DGL is a processed form of licorice that has had most of its glycyrrhizin removed, which is the compound associated with several adverse health effects. Proponents suggest that DGL may help alleviate symptoms of gastroesophageal reflux disease (GERD) and other digestive issues. However, the scientific evidence supporting these claims is limited and warrants a closer examination.

What We Know

1. Definition and Composition: DGL is a form of licorice that has been processed to remove glycyrrhizin, which can lead to side effects such as high blood pressure and hormonal imbalances 29.

2. Potential Benefits: Some studies and health articles suggest that DGL may help soothe the stomach lining and reduce inflammation, potentially alleviating symptoms of acid reflux and GERD 348.

3. Limited Evidence: The consensus among various health sources is that while DGL is commonly used for digestive issues, the scientific research backing its efficacy for acid reflux is limited and not robust 345.

4. Safety Concerns: While DGL is generally considered safer than regular licorice due to the removal of glycyrrhizin, there are still contraindications for certain populations, such as pregnant individuals or those with specific health conditions 29.

5. Alternative Treatments: Other natural remedies and lifestyle changes are often recommended for managing acid reflux, including dietary modifications and over-the-counter medications 14.

Analysis

The evidence surrounding the effectiveness of DGL for acid reflux is mixed and often anecdotal.

• Source Evaluation:

  • Healthline and Medical News Today are generally considered reliable sources, as they often reference scientific studies and expert opinions. However, both articles acknowledge the limited research available on DGL's effectiveness for acid reflux 23.
  • Verywell Health provides a balanced view but also emphasizes the lack of substantial research supporting DGL's benefits, which is crucial for readers seeking evidence-based information 4.
  • Dr. Axe and Health Orchard present more positive views on DGL, but these sources may have a bias towards promoting natural remedies, which could influence their presentation of the evidence 68.
  • Posivi provides a cautionary perspective on who should avoid DGL, which is important for understanding its safety profile 9.

• Methodological Concerns: Most of the claims regarding DGL's benefits come from observational studies or anecdotal reports rather than large-scale clinical trials. This raises questions about the reliability of the findings and whether they can be generalized to the broader population.

• Conflicts of Interest: Some sources promoting DGL may have financial interests in herbal supplements, which could bias their claims. It is essential to consider the motivations behind the promotion of such remedies.

Conclusion

Verdict: Mostly False

The claim that DGL is effective for treating acid reflux is deemed "mostly false" due to the limited and inconclusive evidence supporting its benefits. While some anecdotal reports and smaller studies suggest that DGL may soothe the stomach lining and reduce inflammation, the overall scientific consensus indicates that robust clinical research is lacking. Many reputable health sources highlight the need for more substantial evidence before endorsing DGL as a reliable treatment for acid reflux.

It is important to note that while DGL may be safer than regular licorice, it is not without potential risks, particularly for certain populations. Additionally, the presence of bias in some sources promoting DGL raises further questions about the reliability of the claims made.

Readers should approach claims about DGL with caution and critically evaluate the information presented. As always, consulting with a healthcare professional is advisable when considering new treatments for health conditions.
