Vitamin B12 is essential for DNA synthesis, red blood cell production, and the protective coating (myelin) around your nerves. Deficiency develops slowly and can cause fatigue, megaloblastic anemia, numbness or tingling in the hands and feet, memory problems, and balance issues. If caught late, some nerve damage can be irreversible, which makes regular testing valuable for people at risk.
