Intrinsic factor is the substance necessary for the absorption of vitamin B12. It is a glycoprotein produced by the stomach's parietal cells and is essential for the binding and absorption of vitamin B12 in the small intestine. Without intrinsic factor, the body cannot effectively absorb vitamin B12, leading to deficiencies. This is particularly important for preventing conditions like pernicious anemia.
