Accepted diagnoses include pernicious anemia (D51.0), documented malabsorption conditions, and confirmed B12 deficiency (E53.8)
The main endogenous antioxidant defense is provided by glutathione (GSH)
Efficacy and tolerability of a cream containing modified glutathione (GSH-C4), beta-Glycyrrhetic, and azelaic acids in mild-to-moderate rosacea: A pilot, assessor-blinded, VISIA and ANTERA 3-D analysis, two-center study (The Rosazel Trial)
Effects of DSIP on Biomarkers of Aging, Life Span, and Tumor Incidence in Female Mice
This step might involve acid-base catalysis by the active-site cysteinyl thiolate (which could explain an effect of the second cysteinyl residue), and/or the conserved lysine residue, yielding GS in analogy to glutathione transferases (Fig
