Comparison with Lower Quality Alternatives Active Reduced L-Glutathione form
For example, GSH-supported formation of Cu + or Fe 2+ can promote Fenton-like reactions that convert H 2 O 2 into highly reactive radicals, thereby damaging cellular macromolecules and promoting multiple forms of cell death 181,182
Compromised TJ integrity is increasingly recognized as a hallmark of pathological conditions including gastrointestinal infections, inflammatory bowel disease (IBD), food allergies, autoimmune disorders, certain gastrointestinal cancers, and metabolic syndromes (Ciorba et al., 2024
GSH has a sulfhydryl group and a glutamyl linkage in its structure 6 , making it a powerful reducing agent and a strong nucleophile that can react with cellular toxicants 81
The reduction of its levels is closely correlated with the occurrence of depression and anxiety
