Glutathione
Three amino acids the body already makes
In plain terms
Glutathione is built from glutamine, glycine and cysteine and occurs naturally in cells. Research focuses on its role in handling oxidative stress, in liver detoxification pathways, and in immune cell function.
Research overview
Glutathione is a tripeptide antioxidant naturally produced in the body, composed of glutamine, cysteine, and glycine. Laboratory research has extensively studied its role as the body's primary endogenous antioxidant, its function in cellular detoxification pathways, and its decline with aging. Studies have investigated its potential applications in oxidative stress research models.
What has been studied
- 1
The cell's main antioxidant
Glutathione is a three-amino-acid molecule that cells produce themselves. It is the primary system cells use to manage oxidative stress.
- 2
Detoxification pathways
It is central to how the liver neutralises certain compounds, and much of the older literature concerns that role.
- 3
Ratio as a marker
Research often measures the ratio of its reduced to oxidised forms as an indicator of how much oxidative stress a cell is under.
- 4
Skin pigment research
A separate body of work has looked at its effect on melanin production in skin-cell models.
