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.

This cycle works well; my hair has stopped falling out, and the ingredients did not cause allergies. I noticed effects after a week, and it did not cause heartburn. Taking it at night improves my immunity and the capsules are convenient.

Improves skin problems
Excellent capsules with convenient dosage. I prefer these over regular pills. Zinc is especially beneficial for those consuming lots of sugar, which depletes zinc levels, causing symptoms like white spots on nails and skin issues. The supplement also helps with heartburn and boosts immunity during stress.
