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.

Minimal heartburn experienced
The quality is superb, and I hardly experience any heartburn. The ingredient quantity is just right. The small size makes it easy to consume quickly, and there’s a large amount in each bottle, allowing for full utilisation.

My family has been consuming it for four months and it's a commendable product for the price. The zinc content is adequate, and fortunately, there has been no heartburn or side effects to date. I do wish it contained 1mg of copper, as zinc can hinder copper absorption, leading to deficiencies over time, such as grey hair. There's a bit of hassle in purchasing and consuming copper separately; hence, I acquire 2mg of copper, which I take independently. Additionally, zinc and copper can interfere with selenium and vitamin C, so I take them at separate times in the evening.
