Glutathione (GSH) is a tripeptide composed of glutamate, cysteine, and glycine, found in virtually every cell in the human body. Often called the 'master antioxidant,' glutathione plays an indispensable role in neutralizing reactive oxygen species, detoxifying xenobiotics and heavy metals, regenerating other antioxidants like vitamins C and E, modulating immune function, and maintaining cellular redox homeostasis. Unlike most antioxidant supplements that work through a single mechanism, glutathione operates through an enzymatic system — glutathione peroxidase, glutathione S-transferase, and glutathione reductase — that provides comprehensive cellular protection. Intracellular glutathione levels decline with age, chronic disease, environmental toxin exposure, and poor nutrition, making it a key biomarker of biological aging and a target for longevity interventions. Research spans decades across thousands of published studies, with clinical investigations into IV glutathione therapy, liposomal glutathione supplementation, and N-acetyl cysteine (NAC) as a glutathione precursor strategy.
Glutathione dosage protocols leverage this master antioxidant tripeptide (γ-L-glutamyl-L-cysteinyl-glycine) to support cellular detoxification, reduce oxidative stress, and maintain redox balance throughout the body[1][2]. As the most abundant intracellular thiol, glutathione plays a central role in neutralizing free radicals, supporting liver function, enhancing immune cell activity, and protecting against environmental toxins[3][4].
Proper storage preserves peptide quality.
Glutathione (GSH) is the body’s most abundant intracellular antioxidant, present in virtually every cell at concentrations of 1–10 mM[7]. As a tripeptide composed of glutamate, cysteine, and glycine, it functions as the primary thiol-based redox buffer, neutralizing reactive oxygen species (ROS), supporting Phase II detoxification pathways, and facilitating the excretion of xenobiotics and heavy metals[1][8]. The reduced form (GSH) donates electrons to neutralize free radicals and is then recycled back from its oxidized form (GSSG) by glutathione reductase[2]. Clinical and preclinical research demonstrates that maintaining optimal GSH levels supports liver function, immune cell activity, mitochondrial protection, and overall cellular homeostasis[3][9].
