Glutathione (GSH) is a naturally occurring tripeptide antioxidant composed of three amino acids:
Cysteine, Glutamic Acid (Glutamate) and Glycine.
It is produced primarily in the liver and found in high concentrations in most cells throughout the body.
Key Functions and Roles
βοΈAntioxidant Defence:
Often referred to as the "master antioxidant," glutathione plays a crucial role in neutralising free radicals, reducing oxidative stress and protecting cells from damage caused by reactive oxygen species.
βοΈDetoxification:
It helps detoxify harmful substances in the liver by binding to toxins, heavy metals and drugs, making them easier to excrete.
βοΈProtein Synthesis and Immune Support:
Glutathione is involved in building and repairing tissues, supporting immune function and regulating cellular processes like DNA synthesis and repair.
βοΈOther Benefits:
It aids in reducing inflammation, improving skin health (e.g., by lightening pigmentation) and potentially slowing age-related decline.
Levels of glutathione can decrease due to factors such as ageing, a poor diet, stress or exposure to environmental toxins, leading to increased oxidative damage.
