Vitamin B complex refers to a group of eight B vitamins, B1, B2, B3, B5, B6, B7, B9 and B12 are essential building block of the body responsible for a number of metabolic processes in the body and provide numerous health benefits such as maintaining the nervous system, energy production, taking care of the skin, hair and nails and improving digestion. They are dissolvable in water, meaning they are processed by the kidneys and removed through urine. Deficiency in said vitamins may, among other disorders cause skin diseases and ultimately lead to onset of canker sores.
Canker sores, also known as mouth ulcers refer to small and painful lesions that appear on the soft tissues inside the mouth, specifically inside the lips and cheeks, base of the gums and on the tongue. They should not be confused with cold sores, as they appear on the outside of the mouth, they are caused by herpes simplex virus and are very contagious. Canker sores occur most frequently in young people and adolescents and women. The precise cause is not known, but some explanations include injury to the soft tissues of the mouth, problems with the immune system, high levels of stress, imbalance in hormones and lack of certain vitamins. They clear up in a matter of few weeks, but that time can be extended if a lack of vitamins and minerals is present.
Recurrent onset of canker sores is known to be related to lack of B9, also called folic acid and B12 vitamins, so be sure to test their levels in the blood if you are experiencing recurring canker sores.
Other signs of deficiency of these vitamins include inflammation to the gums or gingivitis, swelling of the tongue and a distinct tingling and burning sensation inside the mouth, a textbook indication of the appearance of mouth sores. Vitamins B9 and B12 can be used as a tablet that you can drink with some water or an injection, in case of a severe deficiency or as a supplement to your daily diet. Foods that contain high levels of these vitamins include meat, poultry and fish such as salmon, eggs, beans and spinach.
Vitamin B2, also known as riboflavin is needed by the body for tissue growth and repair, such as skin and soft tissues. Deficiency in B2 triggers ariboflavinosis, a disease whose symptoms consist of sore throat, cracks that form on the edges of the mouth, swelling of the tongue and other soft tissues inside the mouth. It does not cause canker sores directly, but can lead to their appearance.
Vitamin B3, or niacin, plays a vital role in metabolism of fats, alcohol and glucose. Deficiency of this vitamin causes pellagra, a disorder in which the immune system is weakened and may lead to the inflammation of the skin and soft tissues.
Similar to riboflavin, lack of niacin does not directly induce an onset of canker sores, but any problem with the immunity and skin can lead to their development.
