Does Vitamin Deficiency Cause Chapped Lips?

When your body does not get enough vitamins, your lips may become dry, cracked, or even form sores—a condition sometimes called cheilitis. Vitamins like B2 (riboflavin) and B3 are important for keeping the skin and mucous membranes healthy. When these vitamins are low, the lips may appear red, sore, or scaly. The research shows that malnutrition, which includes vitamin deficiencies, can affect the mouth and lips. For example, some studies have discussed how not having enough vitamins can lead to changes in the mouth’s lining, sometimes causing inflammation or discomfort on the lips. Signs of vitamin deficiency in the mouth are often connected with other health issues caused by poor nutrition. It is important to have a balanced diet that includes essential vitamins to keep your lips and overall body in good shape. If someone is worried about their lips or overall nutrition, they should talk to a healthcare provider who can evaluate their diet and recommend changes or supplements if needed.
