Description
Research Overview
Glutathione is a naturally occurring tripeptide composed of glutamic acid, cysteine, and glycine. It is one of the most abundant intracellular antioxidants and is widely studied in laboratory research for its role in cellular redox regulation, oxidative stress, detoxification pathways, mitochondrial function, and cellular metabolism.
Glutathione is an investigational research compound when supplied for laboratory use and is provided by Marsden Research Labs exclusively for qualified laboratory research applications. It is not offered for human or veterinary use.

Mechanism of Action
Glutathione functions as a major intracellular antioxidant and reducing agent. Laboratory studies have investigated its role in maintaining cellular redox balance, neutralizing reactive oxygen species (ROS), supporting glutathione-dependent enzyme systems, regulating mitochondrial function, participating in xenobiotic metabolism, and maintaining protein thiol homeostasis. It also serves as an important cofactor in numerous enzymatic detoxification pathways.
Because of its fundamental biological role, Glutathione is frequently investigated in oxidative stress research, mitochondrial biology, cellular metabolism, detoxification pathways, aging biology, and redox signaling.
