Glutathione is a powerful antioxidant naturally produced by the body's cells. Composed of three amino acids—glutamine, cysteine, and glycine—it is essential for combating oxidative stress, supporting the immune system, and detoxifying harmful substances. [1, 2, 3]
Key Functions & Health Roles
Antioxidant Defense: Glutathione neutralizes free radicals and reactive oxygen species that can cause cellular damage and inflammation. [1, 2]
Detoxification: It plays a vital role in the liver by binding to toxins, environmental pollutants, and drugs, making them water-soluble so they can be excreted. [1, 2, 3, 4]
Cellular Maintenance: It helps maintain the reduced state of cellular proteins, regulates the cell cycle, and supports mitochondrial function. [1, 2, 3, 4, 5]
Supplements & Medical Uses
Natural glutathione levels decrease due to aging, chronic stress, poor nutrition, and toxin exposure. It is available in various supplemental forms, though its oral absorption is still a subject of research: [1, 2, 3, 4]
Oral Supplements: Taken to support overall wellness or specific conditions like non-alcoholic fatty liver disease (MASLD) or insulin resistance. [1]
Intravenous (IV) Therapy: Used in clinical settings to treat specific conditions, such as severe acetaminophen overdose (often utilizing its precursor, N-acetylcysteine). [1, 2]
Skin Care: Topicals or injectables are heavily marketed for skin lightening, though these uses remain poorly studied and lack well-defined efficacy. [1]
For further details on its mechanisms or the clinical evidence surrounding supplementation, you can explore the National Cancer Institute Drug Dictionary or review scientific discussions in the PMC Library.
Disclaimer: Consult with a healthcare professional before making any changes to your diet or beginning any new supplement regimen. [1, 2]
