L-Glutathione – 600mg
L-Glutathione – 600mg. L-Glutathione is a naturally occurring tripeptide extensively studied in published research for its role as a central intracellular antioxidant and in Phase II detoxification pathways. Supplied at research-grade purity for laboratory use only.
$75.00
L-Glutathione (gamma-glutamyl-cysteinyl-glycine) is a tripeptide synthesized endogenously in nearly all human and mammalian cells from glutamate, cysteine, and glycine. It is one of the most extensively studied endogenous antioxidant compounds in the published biochemical literature, owing to its role in maintaining cellular redox balance and supporting detoxification pathways.

What is L-Glutathione?
Glutathione’s reactive thiol (sulfhydryl) group allows it to directly neutralize reactive oxygen species and to serve as a cofactor for glutathione peroxidase and glutathione S-transferase enzyme families, which are studied for their role in cellular antioxidant defense and Phase II xenobiotic detoxification, respectively. Published research has also examined glutathione’s relevance to immune cell function, given reports that lymphocyte proliferation and cytokine production are sensitive to intracellular glutathione status in tested cell models.

Research Applications
Oxidative Stress & Cellular Antioxidant Research
Published in vitro and animal-model research has examined intracellular glutathione depletion and repletion in relation to markers of oxidative stress, reporting that reduced glutathione status is associated with increased susceptibility to oxidative cell damage across a range of tested cell types.
Hepatic Detoxification Research
Preclinical research has studied glutathione conjugation as a Phase II detoxification pathway for a range of xenobiotic and reactive metabolic intermediates in hepatic cell and animal models, with study authors describing glutathione availability as a determinant of detoxification capacity in the models tested.
Immune Cell Function Research
Cell-based research has examined the relationship between intracellular glutathione concentration and lymphocyte activation, proliferation, and cytokine-production measures, reporting altered immune cell function under experimentally induced glutathione depletion in tested models.
