It takes approximately 24 hours for the absorption of vitamin B12. For quicker absorption, you can get a B12 shot.
Yes
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.
If you have this problem, you might have a problem in your small intesine's terminal ileum where B12 is absorbed.
The best time to eat a vitamin B-complex is during a meal. This way, it is absorbed quickly into the bloodstream.
Which of the following is absorbed in significant quantities by the stomach?
Pernicious anemia is due to a deficiency of a vitamin called intrinsic factor, which is normally produced by cells of the stomach. Intrinsic factor is required for the absorption of vitamin B12, so if intrinsic factor levels are insufficient, vitamin B12 will not be absorbed well. So administration of vitamin B12 will only help treat vitamin B12-deficiency anemia if vitamin B12 can be absorbed, and this can only happen if there are adequate levels of intrinsic factor to begin with. Patients with pernicious anemia do not have adequate intrinsic factor levels, so they will not be helped by vitamin B12 treatment since they can't absorb it well enough.
B12 is a vitamin
The B vitamins are water soluble, which means that what is not used immediately by the body is excreted in the urine vitamin B12 can be stored in the liver for a long time. Vitamin B12 is available in certain food sources, such as meat, dairy and eggs. If you are a vegetarian, or don't consume these foods in high amounts, you should take a vitamin B12 supplement to prevent a deficiency.
Vitamin B12 is a water-soluble vitamin.
B12 is mentioned by most nutritionists. Protein and calcium, although not vitamins, are available in less quantities in vegan food. I'm a vegetarian so I would highly recommend B12 and Vitamin D. Be sure to take in enough proteins and calcium so you don't become malnourished as well.
No, vitamin B12 is not a barbiturate
