Background. Vitamin B12 is an essential water-soluble vitamin that is commonly found in a variety of foods, such as fish, shellfish, meat, eggs, and dairy products. Vitamin B12 is frequently used in combination with other B vitamins in a vitamin B complex formulation.itamin B12 is bound to the protein in food. Acid in the stomach releases B12 from protein during digestion. Once released, B12 combines with a substance called intrinsic factor (IF) before it is absorbed into the bloodstream.
Vitamin B12 is a nutrient that helps keep the body's nerve and blood cells healthy and helps make DNA, the genetic material in all cells. Vitamin B12 also helps prevent a type of anemia called megaloblastic anemia that makes people tired and weak.Two steps are required for the body to absorb vitamin B12 from food.First, hydrochloric acid in the stomach separates vitamin B12 from the protein to which vitamin B12 is attached in food.After this, vitamin B12 combines with a protein made by the stomach called intrinsic factor and is absorbed by the body.Some people have pernicious anemia, a condition where they cannot make intrinsic factor.fter this, vitamin B12 combines with a protein made by the stomach called intrinsic factor and is absorbed by the body.
