Why Absorption Matters: The B12 Challenge The journey of B12 from your plate to your cells involves several steps: B12 from food is bound to proteins and must be released by stomach acid It then binds to intrinsic factor, a protein produced by the stomach This complex travels to the small intestine where B12 is absorbed Finally, it enters the bloodstream for transport to cells This elaborate process explains why many people, despite adequate dietary intake, may still experience functional B12 deficiency
the common sites are palate and gingiva and there is no sex predilection (5, 10)
This was attributed mostly to the gastric physiology, causing formulation dilution in the presence of additional fluid as well as fast transit of liquids into the duodenum, where peptides liable to proteolytic degradation such as the one used in this study showed a negligible absorption, potentially also due to a lower permeation-enhancing capability of CHONAC in the duodenal region
In particular, arginine*1 is a source of nitric oxide useful for the process of capacitation (ability to fertilize) and for the acrosome reaction (changes of the sperm head that allow it to enter the egg to fertilize it) of the spermatozoa
