• glutathione 1500mg for research

Glutathione (GSH) is the most abundant intracellular antioxidant, present in virtually all mammalian cells at millimolar concentrations . This tripeptide (gamma-Glu-Cys-Gly) is synthesized from glutamate, cysteine, and glycine, with the thiol group of cysteine providing its reducing power . As the cell’s primary buffer against oxidative stress, GSH participates in detoxification of reactive oxygen species and xenobiotics, supports the function of glutathione peroxidase enzymes, and maintains protein thiol status . Our glutathione 1500mg for research offers a reliable, high-purity compound for oxidative stress, detoxification pathway, and mitochondrial research studies . 

What is Glutathione 1500mg?

• glutathione 1500mg for research

Glutathione (CAS 70-18-8, molecular formula C10H17N3O6S) is a tripeptide composed of glutamic acid, cysteine, and glycine . The cellular glutathione system operates in a redox cycle: reduced GSH is oxidized to GSSG (glutathione disulfide) when neutralizing oxidants, and glutathione reductase regenerates GSH using NADPH. Monitoring the GSH/GSSG ratio is a standard measure of cellular redox status—a low ratio indicates oxidative stress .

Key identifiers:

• CAS Number: 70-18-8 

• Molecular Formula: C10H17N3O6S

• Sequence: γ-Glu-Cys-Gly (tripeptide) 

• Synonyms: Reduced glutathione, L-glutathione, GSH

• Purity: ≥99% verified by HPLC

Mechanism of Action in Research

Cellular Antioxidant Defense

Glutathione serves as the primary intracellular antioxidant, directly scavenging reactive oxygen species (ROS) and reactive nitrogen species. It plays a role as a sulfhydryl (SH) group provider for direct scavenging reactions catalyzed by glutathione peroxidase and as a scavenger of vitamin E and vitamin C radicals .

Redox Cycle and Glutathione Homeostasis

The GSH/GSSG ratio is a key indicator of cellular redox status. Supplementing cells or tissues with exogenous GSH provides direct antioxidant capacity and supports this redox cycle. Research applications include oxidative stress models, liver toxicity studies (the liver is the main GSH-producing organ), immune cell function (lymphocytes have high GSH requirements), and mitochondrial biology .

Detoxification Pathways

Glutathione participates in Phase II liver enzyme detoxification pathways, supporting the elimination of xenobiotics and heavy metals . It eliminates heavy metals (mercury, lead, cadmium) as well as organic toxins through conjugation reactions .

Scientific Research Applications

Glutathione has been the subject of 24,542 peer-reviewed publications indexed in PubMed . Key research applications include:

Oxidative Stress and Redox Signaling Research

• Cellular redox status and GSH/GSSG ratio monitoring 

• ROS/RNS scavenging mechanisms

• Protection against DNA damage 

Detoxification Pathway Studies

• Phase II liver enzyme research 

• Heavy metal and organic toxin elimination 

• Mitochondrial integrity and function 

Mitochondrial Research

• Mitochondrial energy production and function 

• Mitochondrial ROS production minimization

• Organelle activity maintenance 

Aging-Related Glutathione Decline Studies

• Age-associated GSH depletion research 

• Cellular senescence and oxidative damage

Important Research Considerations

In Vivo Administration: Orally administered GSH is substantially degraded in the GI tract and poorly absorbed intact. For systemic antioxidant effects in animal models, IV or IP administration is more reliable. N-acetylcysteine (NAC) is often used as an alternative because it provides cysteine for intracellular GSH synthesis and has better oral bioavailability .

Third-Party Testing: Independent testing of selected batches has demonstrated an average HPLC purity of 99.3% , with some batches reaching 99.73% purity .

Redox Pair Monitoring: The GSH/GSSG ratio is a standard measure of cellular redox status—a low ratio indicates oxidative stress .
