The "L" in L-glutathione refers to the molecular structure of the amino acids that build the compound
Cysteine is the limiting amino acid for the bodys synthesis of glutathione so it does make sense that oral NAC can increase cellular levels

The adoption of emerging strategies, including rational surface engineering (mucoadhesive ligands, receptor-targeting motifs), protease- and acid-resistant peptide motifs, hybrid proteinpolysaccharide assemblies, and stimuli-responsive designs, will help address these limitations
The induced processes secondarily lead to the intensification of lysis involving NK cells, synthesis and release of IL6, IL1, and IL2, as well as suppression of interferon-gamma synthesis (77)
These peptides work by neutralizing free radicals, thus helping to protect cells from damage and supporting detoxification processes in the body
