If your tiredness feels deep, heavy, and unrelenting, it could be more than just burnout.
#8: Numbness and Tingling in Hands or Feet
Have you ever felt a “pins and needles” sensation that just won’t stop? That tingling could be nerve damage—one of the earliest and most concerning signs of B12 deficiency.
B12 is essential for maintaining the protective sheath around your nerves. Without it, electrical signals misfire, causing tingling, numbness, or even balance problems.
You might think it’s poor circulation—but the real culprit could be microscopic nerve deterioration.
#7: Pale Skin or a Yellowish Tint
Your skin can reveal what your blood can’t hide. When your body lacks B12, it can’t make enough red blood cells. The ones it does make are large and fragile, breaking apart easily and releasing bilirubin—a yellow pigment.
That’s why people with B12 deficiency may develop pale or slightly yellowish skin, resembling anemia or liver issues.
