Vitamin B12, or cobalamin, is an essential nutrient for the proper functioning of the human body. It plays a key role in the production of red blood cells, the maintenance of the nervous system, and energy metabolism. The body cannot produce it on its own, so it must be obtained through diet or supplements, primarily from animal-based sources such as meat, fish, eggs, and dairy. A deficiency in B12 can lead to fatigue, weakness, neurological problems, and anemia. It is especially important for vegetarians, vegans, and individuals with absorption issues to monitor their B12 levels.
