According to the National Institutes of Health, deficiencies in several B vitamins, particularly riboflavin (B2), can be linked to a condition called angular cheilitis, which manifests as painful cracks at the corners of the mouth. This condition is often a sign of underlying nutritional issues that require attention.

According to the MSD Manual, a painful, cracked condition at the corners of the mouth, known as angular cheilitis, is most commonly associated with a deficiency of riboflavin (vitamin B2) and other B vitamins.
