Does Vitamin B Deficiency Cause Mouth Ulcers?

Yes, a deficiency in certain B vitamins, particularly B1 (thiamine), B2 (riboflavin), B3 (niacin), B6 (pyridoxine), B9 (folate), and B12 (cobalamin), can contribute to the development of mouth ulcers. These vitamins play essential roles in maintaining the health of the mucous membranes, which include the lining of the mouth.

A deficiency in B vitamins may lead to a condition known as angular stomatitis or cheilosis, which can cause cracks and sores in the corners of the mouth. Additionally, deficiencies in folate and B12 can contribute to the development of ulcers in the oral cavity.

It’s important to note that other factors, such as poor oral hygiene, certain medical conditions, and viral infections, can also contribute to the development of mouth ulcers. If you suspect a vitamin B deficiency and are experiencing recurrent mouth ulcers, it is advisable to consult with a healthcare professional for a proper diagnosis and appropriate treatment. They may recommend dietary changes, supplements, or other interventions based on the specific deficiency identified.
