Vitamin B12 Absorption Physiology at Norbert Severino blog

Vitamin B12 Absorption Physiology. In normal humans the absorption of vitamin b 12 from foods has been shown to vary depending on the quantity and type of protein. This review explores the physiology of vitamin b12 absorption and the mechanisms and diseases that produce malabsorption. Approximately 1.2% of vitamin b12 is absorbed passively without the help of intrinsic factor. Under physiological conditions, vitamin b12 bound to the gastric intrinsic factor is internalized in the ileum by a highly specific. Intrinsic factor is a glycoprotein produced by parietal cells in the stomach and necessary for the absorption of vitamin b12 in the terminal ileum. Vitamin b12 bound to protein in foods must undergo an initial or early separation reaction before it can be absorbed in the ileum of the small intestine, whereas most forms found in supplements do. If a patient receives the oral formulation at high doses, this passive. The absorption and distribution of dietary vitamin b12 to the organism is a complex process involving several gene products including. In individuals with symptomatic b 12 deficiency despite normal dietary b 12 intake, b 12 malabsorption is the most likely cause and should guide parenteral therapy. Once absorbed, vitamin b12 is.
