About Glutathione
Glutathione (GSH) is a tripeptide made up of three amino acids — glutamate, cysteine, and glycine — and is produced endogenously in nearly every cell of the body. Often called the "master antioxidant," glutathione plays a central role in neutralizing reactive oxygen species and recycling other antioxidants such as vitamins C and E, making it a foundational component of the body's defense against oxidative stress.
Beyond its antioxidant function, glutathione is a critical cofactor in Phase II liver detoxification, where glutathione S-transferase enzymes conjugate it to toxins, drug metabolites, and heavy metals to facilitate their elimination. Glutathione has also drawn substantial research interest in dermatology, where studies have examined its effects on tyrosinase inhibition and a shift in melanin synthesis from eumelanin (darker) toward pheomelanin (lighter), forming the basis for ongoing skin-pigmentation research.
Research Applications
Glutathione is used in research investigating oxidative stress, hepatic detoxification pathways, immune cell function, and melanogenesis (pigmentation). It is frequently studied in combination with other antioxidant and longevity-focused compounds as part of broader investigations into cellular protection mechanisms.
