Vitamin B12 is not created by the human body, so people must get vitamin B12 from their diet. Vitamin B12 is crucial for making DNA and red blood cells and it helps support the nervous system. Vitamin B12 also plays a vital role in the production of blood cells. Experiencing this unusual sign on your mouth could be a warning sign that you’re lacking vitamin B12.

Vitamin B12 are usually found in the same foods and have overlapping roles in terms of health.
This means a deficiency in any single B-complex vitamin is likely to be accompanied by deficiencies in other vitamins.
According to a study in the Journal of the Academy of General Dentistry, several B-complex vitamins are vital to one’s health.
When a person is deficient in vitamin B12, they may experience various oral problems, ranging from cracked lips to tongue inflammation or even ulcers in their mouth.
If a person notices cracked lips on both sides of their mouth it could mean they’re deficient in vitamin B12.
People who experience this condition will have dry, red lips that crack on one or both sides of their mouth.
This condition is specifically known as angular cheilitis and is essentially an inflammation of the lips.
These cracks may be itchy and painful; they may form white scabs and even bleed. When angular cheiltiis occurs over a long period of time, it can cause an infection.

What is angular cheilitis?
Angular cheilitis causes swollen red patches in the corners on the outside of the lips.
It can occur on one or both sides of the mouth. It’s an inflammatory condition and can last a few days or be a chronic problem.
Symptoms can vary from having only mild redness to having open, bleeding blisters.
Dr Scurr said: ”Experiencing angular cheilitis could be due to a vitamin B12 deficiency.
“If the cracks are accompanied by a sore tongue it’s a less common sign of a vitamin B deficiency. This is most likely because a person is not eating fruit, vegetables and wholegrain foods – all good sources of vitamin B.”
If you’re worried about having a B12 deficiency eat more foods such as animal liver, clams, sardines, beef, fortified cereal or tuna. You can speak to your GP about B12 injections.
