Fissures at the corners of the mouth, also known as angular cheilitis, are often associated with deficiencies in specific B vitamins, particularly riboflavin (B2) and niacin (B3). Riboflavin plays a crucial role in maintaining healthy skin and mucous membranes, and a deficiency can lead to cracks and lesions around the mouth. Similarly, niacin is important for skin health and its deficiency can also manifest in similar ways.

While other nutrient deficiencies might cause various symptoms, such as those from vitamin C or iron deficiencies, they do not directly lead to fissures at the corners of the mouth as prominently as riboflavin and niacin do. Vitamin D is more closely related to bone health and calcium absorption, and folate and B12 deficiencies typically result in anemia and other systemic issues rather than localized skin conditions. Therefore, riboflavin and niacin are the most relevant nutrients connected with this particular symptom.
