Cobalamin, also known as vitamin B12, is an essential nutrient that plays a crucial role in various bodily functions. In this article, we will discuss the uses of cobalamin, its sources, and the side effects of deficiency.
Uses of Cobalamin
Cobalamin is essential for the formation of red blood cells, DNA synthesis, and nervous system function. It is also necessary for the metabolism of fatty acids and amino acids. Cobalamin plays a critical role in maintaining the health of nerve cells and the production of neurotransmitters that regulate mood. It also helps to convert homocysteine to methionine, which is essential for cardiovascular health.
Sources of Cobalamin
Cobalamin is found mainly in animal-based foods such as meat, fish, poultry, eggs, and dairy products. Some plant-based foods such as fortified cereals and nutritional yeast also contain cobalamin. The body can store cobalamin in the liver for several years, making it less likely for deficiency to occur in individuals who consume a balanced diet.
Side Effects of Deficiency
Cobalamin deficiency can lead to a wide range of symptoms, including fatigue, weakness, and anaemia. It can also cause neurological symptoms such as tingling and numbness in the hands and feet, difficulty walking, and memory loss. Long-term deficiency can result in irreversible nerve damage. Vegetarians and vegans are at higher risk of developing a deficiency due to the limited availability of cobalamin in plant-based foods.
Treatment of Deficiency
Cobalamin deficiency can be diagnosed through a blood test, and treatment often involves cobalamin supplements. Injections or high-dose supplements may be necessary for those with severe deficiency. Treatment can reverse many of the symptoms of deficiency, but nerve damage may be irreversible in some cases.
