Cytoprotective Mechanism of the Novel Gastric Peptide BPC157 in Gastrointestinal Tract and Cultured Enteric Neurons and Glial Cells

The millimolar GSH intracellular concentrations, the low plasma micromolar concentrations and the low GSH redox potential ( E 0 = 240 mV) make GSH an ideal and perfect cellular redox buffer (Figure 2) ( FIGURE 1 FIGURE 2 Glutathione is synthesized in the cytosol of all cells from their precursor amino acids: glutamic acid, cysteine and glycine by consecutive action of two enzymes: -glutamyl-cysteine (-GluCys) synthetase (also known as glutamate cysteine ligase, GCL) that in a first step uses glutamate and cysteine as a substrate to form the dipeptide -glutamyl-cysteine

Unless the argument is that those people can access their B12 stores and you cannot, but I don't think we can assume that
