In this brief educational video, the speaker explains that intrinsic factor is a glycoprotein secreted by the stomach's parietal cells. Its primary function is to bind vitamin B12 and enable its absorption in the small intestine. Vitamin B12 is essential for the production of healthy red blood cells; without sufficient intrinsic factor, B12 cannot be absorbed effectively, leading to reduced formation of healthy red blood cells and potential anemia.
Intrinsic factor is a glycoprotein that's released by the parietal cells in the stomach. It is needed for the body to absorb vitamin B12, which is required to make healthy red blood cells. Without B12, the body cannot make enough healthy red blood cells to support the needs and functions of the body. And intrinsic factor plays a critical role in the body's ability to absorb that vitamin B12. So without enough intrinsic factor, there are less healthy red blood cells in the body.
