Quizplus · Accepted Answer

Vitamin B₁₂, also known as cobalamin, requires intrinsic factor for absorption. Intrinsic factor is a protein that is produced by cells in the stomach lining and is necessary for the absorption of vitamin B₁₂ in the small intestine. Without intrinsic factor, vitamin B₁₂ cannot be absorbed and a deficiency may result. While lipids may aid in the absorption of some vitamins, this is not unique to vitamin B₁₂. Magnesium is not required for the activity of vitamin B₁₂ and an acidic intestinal environment is not necessary for its synthesis.
