Abstract: Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a vital role in numerous physiological functions, including red blood cell formation, neurological function, DNA synthesis, and energy metabolism. Despite its essential nature, the human body cannot synthesize Vitamin B12 and must rely on dietary intake or supplementation. This review explores the biochemical structure, absorption mechanisms, dietary sources, and diverse functions of Vitamin B12 in maintaining human health. Particular attention is given to the complex absorption process involving intrinsic factor, its storage in the liver, and the clinical implications of deficiency, which can lead to megaloblastic anemia and irreversible neurological damage. The review also examines risk factors for deficiency, including dietary restrictions, gastrointestinal disorders, and aging. Furthermore, it discusses diagnostic markers, therapeutic approaches, and current research highlighting emerging roles of Vitamin B12 in cardiovascular health, cognitive function, and mood regulation. Understanding the multifaceted role of Vitamin B12 is crucial for effective prevention, diagnosis, and treatment of related disorders, as well as for guiding future nutritional and medical research.
