B12 is a vitamin also known as cobalamin and it is essential in several physiologic processes.  B12 critical for the function of blood cells and nerves. Deficiencies can be caused by inability to absorb B12 in the diet. People with gastrointestinal disorders such as Crohn’s’ disease or Celiac disease may become deficient. Humans cannot make B12 and it is found in meat and animal products but not in plant-based diets. Strict vegetarians are at risk for B12 deficiency without supplementation.  A B12 shot can rapidly replenish a deficiency.


Many people with B12 deficiency may no have any symptoms and may be unaware their health is at risk. Symptoms of B12 deficiency can include:

  • Weakness, tiredness, or lightheadedness
  • Heart palpitations and shortness of breath
  • Pale skin
  • A smooth tongue
  • Constipation, diarrhea, loss of appetite, or gas
  • Nerve problems like numbness or tingling, muscle weakness, and problems walking
  • Vision loss
