Therefore, it is reasonable using supplementation of liposomal glutathione, instead of the N-acetylcysteine or bonded cysteine utilized as precursors for GSH cell synthesis, since patients with deficient levels of glutamate-cysteine ligase and GSH synthetase will not be able to use N-acetylcysteine or bonded cysteine as substrates to synthesize their own GSH
For patients who rely on peptide therapy for recovery, immune support, metabolic health, and longevity, this is significant news

Trp is metabolized to Kyn by tryptophan 2,3-dioxygenase or indoleamine 2,3-dioxygenase in the Kyn pathway, and to 5-HT by tryptophan hydrolase (TH) and aromatic amino acid decarboxylase (AAD) in the serotonin pathway (Fig
