Vitamin B12 function: Vitamin B12 (cobalamin) is a water-soluble vitamin that plays a crucial role in red blood cell formation, DNA synthesis, and maintaining normal nerve function. It is also important for protein and fat Metabolism. Vitamin B12 is obtained from animal-based foods, and its deficiency can lead to macrocytic Anemia, fatigue, memory problems, and nerve damage.
