In animal-based diets the vitamin B12 bonds to protein molecules. When digested stomach acids cause it to be separated from the protein. In addition, an ingredient called intrinsic factor allows body’s bloodstream to absorb the vitamin.

A few people’s bodies fail to produce sufficient stomach acid or intrinsically if they suffer from an illness called an autoimmune gastritis. People with this condition may require Vitamin B12 shots to decrease their risk of being deficient, which can cause pernicious anemia.
