In the United States, between 1.5% and 15% of people are deficient in vitamin B12.

People over 50 should consume the majority of vitamin B12 in dietary supplements because they can not get this vitamin naturally from food.

People who have undergone gastrointestinal surgery, for example to lose weight, or those who suffer from digestive disorders, such as celiac disease or Crohn’s disease. These can reduce the amount of vitamin B12 that the body can absorb.
