As described in section A Model for Changes in MRS Measured Glutamate, GABA, and Glutamine Levels During the Progression of ALS and Figures 1, 2, the measured level of glutamate may reflect a competition between increases in glutamate levels in hyperexcitable glutamatergic neurons vs
An intake of several small doses only makes sense in healthy people, in which the intake through the intrinsic factor is full or adequate
Vitamin B12 can then be absorbed into the bloodstream via endocytosis in the distal ileum, or by passive diffusion in the absence of intrinsic factor.2 Pernicious anemia (an autoimmune disease) affects the gastric mucosa, leading to destruction of parietal cells and failure to produce intrinsic factor, resulting in vitamin B12 malabsorption and eventually deficiency
