B12 Supplements
Vitamin B12 plays a key role in the production of DNA and helps keep blood cells healthy. A lack of this nutrient might increase the risk of mouth ulcers. Good sources of vitamin B12 include milk products, milk, eggs, meat, and poultry. The risk is especially high in vegans and those who have a plant-based diet. In these cases, you can choose some vegan sources, such as seaweed, tofu, tempeh, fortified seitan, fortified cereals, nutritional yeast, and fortified plant milk like coconut, soy, or almond. In case you cannot take in sufficient vitamin B12 due to dietary restrictions or allergies, then you can also consult your healthcare provider to take vitamin B12 supplements to ensure the daily recommended intake.
