Which vitamin should a child with mouth ulcers take?

When children have mouth ulcers, consider supplementing the following vitamins to assist treatment: 1. B-complex vitamins: B-complex vitamins are essential nutrients involved in the metabolism of oral mucosal cells, including vitamins B1, B2, B3, etc. Deficiency in these vitamins may damage the oral mucosa and increase the risk of ulcers. Therefore, supplementing B-complex vitamins can help promote repair and regeneration of the oral mucosa. 2. Vitamin C: Vitamin C helps boost immunity, protects the oral mucosa from external damage, and promotes its healing. Although vitamin C cannot directly cure mouth ulcers, it can serve as an adjunctive treatment to help speed up the healing process. Parents should also ensure their child maintains a balanced diet and consumes more foods rich in vitamins.
