Heartburn, often caused by gastroesophageal reflux disease (GERD), can potentially be managed or alleviated with certain dietary supplements. Several studies have explored the efficacy of various supplements in reducing symptoms. Here are some that might help:

1. Melatonin: Studies suggest that melatonin might be as effective as omeprazole (a common GERD medication) in reducing GERD-related symptoms[^1^][^2^].
2. STW 5 (Iberogast): This is a commercial formula that includes nine botanicals and has been shown to be effective for symptoms such as epigastric pain, retrosternal pain, and acid regurgitation[^1^].
3. Probiotics: Specifically, strains like Lactobacillus acidophilus, Bacillus subtilis, and Enterococcus faecium may improve GERD symptoms and overall gut health[^3^][^4^].
4. Ginger: Ginger supplementation has shown promise in alleviating symptoms of functional dyspepsia, which often overlaps with GERD symptoms[^5^].
5. Deglycyrrhizinated Licorice (DGL): This variant of licorice is believed to soothe the esophagus lining and has been suggested as a beneficial supplement for GERD[^6^].
