Which vitamin requires intrinsic factor which is secreted by the stomach in order to be absorbed?
Intrinsic factor is a glycoprotein secreted by parietal (humans) or chief (rodents) cells of the gastric mucosa. In humans, it has an important role in the absorption of vitamin B12 (cobalamin) in the intestine, and failure to produce or utilize intrinsic factor results in the condition pernicious anemia.
What will happen if intrinsic factor is not secreted in stomach?
Intrinsic factor is a natural substance normally found in the stomach. You need this substance to absorb vitamin B12 from foods. A lack of intrinsic factor leads to pernicious anemia and vitamin B12 deficiency, which can cause anemia and brain and nervous system (neurological) problems.
What reduces intrinsic factor?
If your body does not make enough intrinsic factor, you can develop a type of vitamin B12 deficiency called pernicious anemia. Surgical removal or bypass of the stomach and certain other health conditions can also cause you to stop making intrinsic factor.
What causes lack of intrinsic factor?
The inability to make intrinsic factor may be caused by several things, such as: Chronic gastritis. Surgery to remove all or part of the stomach (gastrectomy) An autoimmune condition, where the body attacks its own tissues.

- Beef, liver, and chicken.
- Fish and shellfish such as trout, salmon, tuna fish, and clams.
