Mouth Ulcers

Lesions in and around the mouth may partly be linked to an insufficient intake of certain vitamins or minerals.

For instance, mouth ulcers, also commonly referred to as canker sores, are often the result of deficiencies in iron or B vitamins.

One small study notes that patients with mouth ulcers appear to be twice as likely to have low iron levels.

In another small study, around 28% of patients with mouth ulcers had deficiencies in thiamine (vitamin B1), riboflavin (vitamin B2), and pyridoxine (vitamin B6).

Angular cheilitis, a condition that causes the corners of the mouth to crack, split, or bleed, can be caused by excess salivation or dehydration. However, it may also be caused by an insufficient intake of iron and B vitamins, particularly riboflavin.

If you experience these symptoms, try adding the nutrients above to your diet to see if your symptoms improve.
