Is taking folic acid effective for treating mouth ulcers?

Taking folic acid is effective for mouth ulcers. As a water-soluble vitamin, folic acid plays a positive role in treating oral ulcers. It can enhance local nutrition of the oral mucosa and promote its self-repair. Folic acid also helps improve anemia and boost the body's immune system, thereby increasing resistance to mouth ulcers. For patients with oral ulcers, oral supplementation with folic acid can be used as an adjunctive treatment. Combined with other treatment methods, such as topical medications or oral drugs, symptoms of oral ulcers can be relieved more effectively. However, folic acid is not the only treatment for oral ulcers, and individual physical conditions and severity of the condition may vary. Therefore, when taking folic acid, it should be supplemented properly under a doctor's guidance to avoid excessive intake that could cause discomfort.
