Description
L-Glutathione is the most abundant antioxidant molecule inside cells and a staple of redox research. Limitless Life Nootropics supplies it as a 500mg vial of reduced GSH with a complimentary reconstitution solution, made in the USA.
What Is L-Glutathione?
Glutathione is a tripeptide made of glutamic acid, cysteine and glycine, linked in an unusual way: the glutamate is joined through its side-chain (gamma) carboxyl group. The thiol (–SH) group on cysteine gives the molecule its reducing power, allowing it to neutralize reactive oxygen species and peroxides and to regenerate other antioxidants such as vitamins C and E.
The ratio of reduced (GSH) to oxidized (GSSG) glutathione is one of the most widely used indicators of cellular oxidative stress. Researchers use the compound in assays of detoxification, protein thiol status and redox signaling. Its CAS number is 70-18-8.
Because of its specific solubility requirements, each vial includes a complimentary 7mL reconstitution solution. The entire solution vial should be used for proper dissolution.
Key Research Areas
The scientific literature describes this peptide across several areas of investigation:
- Oxidative stress and GSH/GSSG ratio assays
- Phase II detoxification and glutathione S-transferases
- Protein thiol and disulfide chemistry
- Mitochondrial redox balance
- Skin pigmentation and melanin research
Researchers can review peer-reviewed studies on glutathione through the National Library of Medicine (PubMed) database.
