Intrinsic Factor

Intrinsic factor is a protein produced by cells lining the stomach that is essential for absorbing vitamin B12, a nutrient needed for healthy blood cells and nerve function. Without intrinsic factor, vitamin B12 cannot be properly absorbed in the small intestine, which can lead to deficiency and related health problems like anemia and nerve damage. Its main role is to bind vitamin B12 in the stomach and carry it through the digestive system to be absorbed efficiently. This process is crucial for maintaining overall health, especially for blood and nerve system functions.
