Vitamin B12 plays an important role in red blood cell formation, nerve function and DNA production. When your body doesn’t get enough, symptoms can sometimes develop gradually.
Constant Fatigue
Feeling unusually tired or weak despite adequate rest may be one sign of B12 deficiency.
Pale or Yellowish Skin
Low B12 can contribute to anaemia, sometimes making the skin look unusually pale.
Tingling or Numbness
Pins-and-needles sensations, especially in the hands and feet, can occur.
Memory or Concentration Problems
Some people may experience difficulty concentrating or changes in memory.
Balance Problems
B12 deficiency can affect nerves and sometimes cause coordination or balance issues.
Sore Tongue
A swollen, painful or unusually smooth tongue can be another sign.
Mood Changes
Irritability or low mood may sometimes occur.
