The phrase "absorption of vitamin" is correct and usable in written English.
It can be used when discussing how the body takes in and utilizes vitamins from food or supplements.
Example: "The absorption of vitamin D is crucial for maintaining healthy bones and immune function."
Alternatives: "uptake of vitamin" or "assimilation of vitamin".
Intrinsic factor is necessary to the absorption of vitamin B12.
It is specifically responsible for the absorption of vitamin B12 and the reabsorption of conjugated bile salts.
The basis of pernicious anemia, then, is a lack of absorption of vitamin B12.
In others, an acquired pathological condition may be responsible for the deficiency (e.g., conditions interfering with absorption of vitamin K and severe infection).
(Vitamin B12 is necessary for red cells to form properly). The basis of pernicious anemia, then, is a lack of absorption of vitamin B12.
Bile is necessary for the absorption of vitamin K. Similar changes may take place when absorption of vitamin K is impaired by conditions such as chronic diarrhea or with the administration of certain antibiotics.
Pernicious anemia occurs when people develop an autoimmune condition that reduces the production of intrinsic factor — and, therefore, the absorption of vitamin B12.
A complex interaction of autoantibodies against the parietal cell proton pump and sensitized T cells progressively destroy the parietal cells, inducing hypochlorhydria and then achlorhydria, while autoantibodies against the intrinsic factor impair the absorption of vitamin B12.
Some people may need a higher dose, however, including those with a bone health disorder and those with a condition that interferes with the absorption of vitamin D or calcium, says Dr. Manson.
Will this condition affect my ability to absorb either folic acid or vitamin B6? Name withheld The absorption of vitamin B12 depends to a large degree on the presence of a substance called intrinsic factor, which facilitates the nutrient's transfer through the gut wall and into the body.
Bacterial overgrowth in the intestines can interfere with glucose absorption, and the stomach's failure to produce a substance called intrinsic factor will prevent the absorption of vitamin B12 (cobalamin), which leads to pernicious anemia.
