Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a critical role in various bodily functions. It is essential for the production of red blood cells, the maintenance of a healthy nervous system, and the synthesis of DNA. Vitamin B12 is primarily found in animal-based foods such as meat, fish, dairy products, and eggs. Vegetarians and vegans are often at a higher risk of B12 deficiency, as they may not get enough from their diets. A deficiency in vitamin B12 can lead to anemia, neurological problems, fatigue, and other health issues. To prevent deficiencies and ensure proper health, individuals at risk or with specific dietary restrictions may need to consider B12 supplements or fortified foods. Regular monitoring of B12 levels through blood tests is also essential for early detection and management of deficiencies.
