Cobalamin

Cobalamin, commonly known as vitamin B12, is a vital water-soluble vitamin that plays essential roles in various bodily functions. It is crucial for the formation of red blood cells, DNA synthesis, and neurological function. Cobalamin is unique among vitamins because it contains the metal cobalt and is primarily obtained from animal-based foods such as meat, fish, poultry, eggs, and dairy products. The body requires an adequate intake of cobalamin to maintain healthy nerve cells and to produce energy from fats and proteins. Deficiency in cobalamin can lead to serious health issues such as pernicious anemia, characterized by the production of large, abnormal red blood cells, and neurological problems like numbness, tingling, memory loss, and cognitive disturbances. Due to its importance, individuals at risk of deficiency, such as vegetarians, vegans, and those with certain medical conditions affecting absorption, may need to take supplements or fortified foods to ensure sufficient levels of this critical nutrient.
