Which vitamin requires intrinsic factor in order to be absorbed?A. B12
B. K
C. A
D. C

Answers

Final answer:

Vitamin B12 requires an intrinsic factor for absorption. The intrinsic factor is a protein produced in the stomach which aids in the absorption of Vitamin B12 in the small intestine. Lack of intrinsic factor can lead to vitamin B12 deficiency.

Explanation:

The vitamin that requires intrinsic factor in order to be absorbed is Vitamin B12. The intrinsic factor is a protein produced by the stomach that is necessary for the absorption of Vitamin B12 in the small intestine. Without the presence of intrinsic factor, Vitamin B12 cannot be effectively absorbed, leading to a potential vitamin B12 deficiency.
