Can you use lemon as antacid?

Lemon juice is acidic due to its high citric acid content, which may seem counterintuitive for use as an antacid. However, some people find that it has an alkalizing effect on the body once metabolized, potentially providing relief from heartburn or indigestion. That said, its effectiveness can vary from person to person, and it may aggravate symptoms in those with certain conditions. Always consult a healthcare professional for persistent issues.
