15 Surprising Symptoms of Vitamin B12 Deficiency

Vitamin B12, medically known as cobalamin, is an important vitamin that is responsible for the development of red blood cells and proper functioning of the brain and nervous system, just to name a couple of its duties. Our bodies don’t naturally produce B12, so we must obtain it through diet. B12 deficiency is a common problem because many people have diets low in animal products (the main dietary source of B12), or problems with vitamin absorption. Some surprising symptoms of vitamin B12 deficiency include:

  1. Paranoia or neuroticism
  2. Depression, problems with mood calibration or behavioral changes
  3. A sore mouth or tongue (or swollen tongue)
  4. Lethargy or fatigue
  5. Anemia
  6. Foggy brain (trouble concentrating or reasoning)
  7. Heart palpitations or arrhythmia
  8. Nerve problems like loss of sensation and impaired mobility
  9. Stomach problems like gas, constipation, bloating or diarrhea
  10. Numbness of the extremities (sometimes can be confused with carpel tunnel)
  11. Vision problems like blurry vision
  12. Weakness, faintness or dizziness
  13. Jaundice (yellowing skin)
  14. Menstrual complications
  15. Shortness of breath

Vitamin B12 is a term referring to various subtypes of B12 nutrients. B12 plays many roles to play in keeping the body healthy such as aiding in proper brain function, DNA synthesis and development of nerves and blood cells. Some people are Vitamin B12 deficient.
