Vitamin B12 can be sourced in similar foods and have intersecting roles in terms of your health. This means that a deficiency in any B-complex vitamin may possibly be accompanied by deficiencies in many other vitamins.

The Odd Sign In The Corners Of The Mouth

In a study published in the Journal of the Academy of General Dentistry, many B-complex vitamins are crucial to your health. If you have a deficiency in vitamin B12, you may experience different oral problems, which can range from having cracked lips to suffering from tongue inflammation. Such deficiencies may even lead to the formation of ulcers in the mouth.

If you notice your lips cracking on both sides of your mouth, including at the corners, it may indicate a deficiency in vitamin B12. Those who have this condition suffer from dry, red lips that may crack on one or both corners of their mouths.

Known as angular cheilitis, this condition is basically a lip inflammation. The cracks can become very itchy and painful. They can also cause the formation of white scabs and bleed. If left unchecked and untreated for a long time, angular cheilitis can cause an infection.

This condition causes the formation of swollen red patches in corners of the outer lips. It may last a couple of days may also become a chronic problem.

Symptoms may differ from experiencing mild redness to suffering from open and bleeding blisters. According to Dr. Scurr, having angular cheilitis may be due to a deficiency in vitamin B12. If a sore tongue accompanies the cracks, this may be because the sufferer is not eating vegetables, fruits, and wholegrain foods.

If you believe you have a deficiency in vitamin B12, you can always include foods like clams, animal liver, tuna, beef, or fortified cereal in your diet. If you are a vegan, however, you can always talk to your doctor about taking B12 supplements.
