Zinc's role in heartburn relief
Esophageal ulcer related to zinc deficiency following a total gastrectomy.
Direct impact on heartburn symptoms
We investigated how zinc affects heartburn through the case of a 76-year-old Japanese man who experienced significant discomfort after undergoing a total gastrectomy. For two weeks, he suffered from a sore throat, heartburn, and difficulty swallowing. Endoscopy revealed deep, craterlike ulcers in his esophagus, but tests for viral infections were negative.

After initial treatment, his symptoms returned, prompting further investigation. Eventually, we found that his serum zinc level was low at 38 µg/dL, which led to a diagnosis of zinc deficiency. Following oral zinc supplementation, the patient reported relief from his symptoms and a noticeable improvement in the esophageal ulcers observed during a follow-up endoscopy.

Over the five years since his treatment, the patient has continued to take zinc supplements and has not faced similar issues again. This case suggests that zinc can play a crucial role in treating heartburn issues related to ulcers, especially in those with a deficiency.

Vitamin C reduces heartburn symptoms
The safety and efficacy of 2% vitamin C solution spray for relief of mucosal irritation caused by Lugol chromoendoscopy: a multicenter, randomized, double-blind, parallel trial.
Highly relevant heartburn treatment study
We investigated how vitamin C, specifically in the form of a 2% vitamin C solution spray, could help alleviate heartburn symptoms following Lugol chromoendoscopy, a procedure that involves staining the esophagus to better visualize abnormalities. In a well-structured study with 240 participants, we used a randomized, double-blind approach to compare the effectiveness of vitamin C to normal saline and sodium thiosulfate solutions.

Our results showed that vitamin C spray significantly reduced both acute heartburn symptoms and late discomfort when compared to the saline solution. Specifically, 33% of participants using vitamin C reported relief from acid regurgitation or heartburn, compared to just 15% with sodium thiosulfate. Additionally, patients noted an improvement in retrosternal pain, with 21% finding relief from the vitamin C treatment versus 9% from sodium thiosulfate.

Furthermore, vitamin C offered a quicker discoloration of the iodine-stained mucosa compared to saline, enhancing the overall experience of the procedure. These findings suggest that incorporating vitamin C spray into post-procedural care could be a helpful strategy for patients facing discomfort after undergoing Lugol chromoendoscopy.

No heartburn felt
I was pleased that there were no unpleasant sensations in my stomach. Unlike usual vitamin C, which increased acidity and caused heartburn, I don’t experience that here. During the covid period at work, many have fallen ill, but I’ve stayed healthy. I take it before bed and today tried it in the morning.

Caused heartburn
Unfortunately, these lozenges did not suit me; they trigger heartburn due to the vitamin C content. However, they're very effective for colds and will help you recover quickly.
