Common Signs of Low Vitamin B12
4. Weakness or Dizziness
Muscle weakness, lightheadedness, or dizziness can occur, particularly when B12 deficiency has led to anemia. These symptoms can have many other causes, so they shouldn’t automatically be attributed to B12.
5. Trouble With Balance or Coordination
More significant or prolonged B12 deficiency can affect nerves responsible for movement and balance. Some people may notice difficulty walking steadily or feel less coordinated.
