Image Credit: DAJ/amana images/Getty Images. As a vitamin, B-12 is distinct from iron, a mineral, in both its composition and function as a nutrient. However, they are interrelated. On the other hand, their relationship with one another is not the extent of their significance.
Pepsin
In food, vitamin B-12 is bound to protein. Your body uses pepsin, an enzyme, to break protein into its component amino acids. The release of pepsin is stimulated by a gastric substance called hydrochloric acid. Pepsin is one of three enzymes that help digest protein, the other two being trypsin and chymotrypsin.
Intrinsic Factor
Intrinsic factor is a protein produced by cells in your stomach lining. It is needed for your intestines to absorb B-12. After B-12 is released by hydrochloric acid and pepsin, pancreatic enzymes bind to B-12 for further digestion, then release B-12 for intrinsic factor to bind to it, which then transports it to your bloodstream.
Sublingual B-12
Some individuals do not produce enough acid, pepsin or intrinsic factor to digest sufficient amounts of B-12 from their diet. Sublingual B-12 is available as a dietary supplement and is designed to bypass stomach digestion.
Injections
If you have pernicious anemia, it is a lifelong condition. Your body is unable to digest B-12 from the food you eat, making it necessary to supplement. Your doctor will primarily prescribe B-12 injections, which are injected into your muscle and are quickly absorbed into your bloodstream.
Risks
