    Glossary Vitamin B12 Deficiency

    insufficient cobalamin impairs red blood cell production and neurological function

    Vitamin B12 Deficiency, also known as Cobalamin Deficiency, occurs when the body lacks sufficient levels of Vitamin B12, an essential nutrient crucial for red blood cell formation, neurological function, and DNA synthesis. Symptoms can include fatigue, weakness, anemia, and neurological issues such as numbness or tingling in the hands and feet. This deficiency can result from inadequate dietary intake, malabsorption issues, or certain medical conditions.
