The vitamin B12 is a very important nutrient; it lowers risk of stroke, Heart disease, cancer, Parkinson's, and Alzheimer's disease. The vitamin begins to absorb in the mouth, in contrast to most nutrients.
Intrinsic Factor is a glycoprotein produced by the parietal cells of the stomach. It is necessary for the absorption of Vitamin B12 (cyanocobalamin) later on in the terminal ileum. A deficiency in the intrinsic factor will lead to pernicious anemia.

Which nutrient requires intrinsic factor for absorption?
Vitamin B12 requires intrinsic factor for absorption in the small intestine. Intrinsic factor is produced by the stomach and binds to vitamin B12 to facilitate its absorption in the ileum. Without intrinsic factor, vitamin B12 absorption is impaired, leading to deficiency.
A protein secreted by the stomach that is necessary for the absorption of vitamin B12?
The protein secreted by the stomach that is necessary for the absorption of vitamin B12 is called intrinsic factor. Intrinsic factor binds to vitamin B12 in the small intestine, allowing for its absorption into the bloodstream. Without intrinsic factor, vitamin B12 cannot be effectively absorbed and can lead to a deficiency.
How long does it take for vitamin b12 to be absorbed?
It takes approximately 24 hours for the absorption of vitamin B12. For quicker absorption, you can get a B12 shot.
Which vitamin need instritic factor for stomach for absortion?
B12 is the vitamin that requires intrinsic factor for absorption. B12 is also known as cobalamin.
Aids in absorption of vitamin b12?
Intrinsic factor, a protein produced in the stomach, helps in the absorption of vitamin B12. This vitamin is crucial for red blood cell formation and neurological function. Absorption of vitamin B12 occurs in the small intestine, where it binds to intrinsic factor for transport into the bloodstream.
What carrier protein is responsible for absorption of vitamin B12?
Intrinsic factor
What enables absorption of b12 across small intestine wall?
Intrinsic factor, a protein produced by the stomach, is required for the absorption of vitamin B12 in the small intestine. In the small intestine, vitamin B12 binds to intrinsic factor, forming a complex that can be absorbed through the intestinal wall.
When does vitamin B12 anemia occur?
Vitamin B12 deficiency anemia is another type of megaloblastic anemia that develops when the body doesn't absorb enough of this nutrient.
Why oral administration of vitamin B12 not effective as a treatment of pernicious anemia?
Oral administration of vitamin B12 is not effective for pernicious anemia because the condition involves a lack of intrinsic factor, which is needed for the absorption of B12 in the intestines. Without intrinsic factor, the intestines are unable to absorb enough B12 from oral supplements to treat the deficiency. In such cases, B12 injections are typically used for effective treatment.
The absorption of which vitamin would be impaired by the removal of the stomach?
Vitamin B12 is released from proteins by concentrated levels of HCL acid in the stomach. Therefore, without the stomach there would be no HCL acid to release the B12
Is B12 a vitamin or a mineral?
B12 is a vitamin
Is b12 bad for you?
If you are referring to vitamin b12, vitamin b12 is healthy for you.
