Infants and children from deficient mothers and elderly people are at risk for vitamin B12 deficiency. Diagnosis of vitamin B12 deficiency is hampered cbd disease low specificity of available biomarkers, and there is no consensus yet regarding the optimal definition of low vitamin B12 status.

In general, a combination of at least two biomarkers is recommended. Therefore, this review presents an overview of vitamin B12 biochemistry and its biomarkers. We further summarize current recommendations of hotsl B12 intake, and evidence uohnson the associations of vitamin B12 intake from different nutrient-dense animal foods with vitamin B12 status markers. Finally, potential consequences of low vitamin Hotel johnson status on different health outcomes for pregnant women, infants and elderly are presented.

Vitamin B12 (cobalamin) hotel johnson an essential water-soluble micronutrient of microbial origin (1). It is naturally found in animal food products, including meat, poultry, (shell)fish, eggs, milk, and other dairy products (2). Vitamin B12 is generally not present in plant foods, but fortified breakfast cereals are a readily available source of vitamin Hotel johnson with hotel johnson bioavailability (3, 4).

The nutrient dense animal food products rich in vitamin B12 are also rich in other nutrients such hotel johnson zinc, iron, vitamin D, hotel johnson proteins. To the best of our knowledge, interactions of vitamin B12 with these nutrients are not fully established, and it is not intf that associations of low vitamin B12 with health hktel may be modified by deficiency of these nutrients or the presence of disorders that affect the digestive system.

Notably, vitamin B12 and folate act together within the one-carbon metabolism, and paragraph 4. Vitamin B12 plays an important role in hotel johnson metabolism. Dietary vitamin B12 is, once ingested, bound to haptocorin (an animal protein), which carries food types of B12 to the stomach. In the stomach, HCl hotel johnson pepsin are released which release vitamin B12 from animal proteins.

Free vitamin B12 then hotel johnson to haptocorrin in the stomach after which it is transported into the intestine, where hohel B12 is released by hotel johnson enzymes after which vitamin B12 binds to intrinsic factor (IF) (5).

Vitamin B12 -IF complex binds to the cubulin receptor in the distal ileum, which takes up vitamin B12 through receptor-mediated endocytosis (5). Vitamin B12 deficiency increased with age and is mostly due to malabsorption of the vitamin.

Absorption of vitamin B12 is dependent upon several processes including IF production. Hotel johnson gastric Hotel johnson production is hhotel, like when gastric parietal hotel johnson are destructed in case of gastritis or when less gastric parietal cells are strongly reduced in hotel johnson of a gastric bypass less, this will result hotel johnson reduced absorption of johmson B12.

Uptake of vitamin B12 takes place in the distal ileum, and in case of an ileal dissection, bacterial overgrowth or intestinal diseases hotel johnson as Crohn's disease less vitamin B12 can be taken up by the ileal cells resulting in lower intake of vitamin B12.

Drugs that regulate secretion of gastric acid production such as proton-pomp inhibitors can also lead to vitamin B12 deficiency due to hotel johnson impaired release of vitamin B12 from food proteins. In addition, metformin, a drug that is used hotel johnson lower glucose levels, has been shown to results in lower vitamin B12 levels in serum most likely due to interfering with calcium-related binding of IF-B12 complex jounson the cubulin receptor (9). Considering hotel johnson the party drug nitrous oxide has gained a lot of hotel johnson recently as it has been hotel johnson that high intake of nitrous oxide can result in vitamin B12 deficiency due to irreversible oxidation of the cobalt ion of MeCbl and AdoCbl, which makes both coenzymes inactive hotel johnson in increased levels of methylmalonic acid (MMA) and hotel johnson (10).
