Glutathione is an endogenous tripeptide (glutamate, cysteine, glycine) that plays a central role in intracellular redox balance and detoxification.

Exogenous glutathione is sometimes administered in wellness, hepatology, and dermatology contexts, though practice and evidence differ by region.

Glutathione participates in antioxidant defenses, conjugation of certain xenobiotics, and maintenance of other antioxidant systems.

Potential roles have been studied in liver disease, oxidative stress states, and cosmetic skin-lightening, among others. Only some of these uses may be supported or approved in specific settings.

Parenteral products require attention to sterility, excipients, and infusion reactions. Cosmetic or wellness uses may not have the same level of evidence or regulatory oversight as labeled medical indications.

Glutathione has poor oral bioavailability, leading to a preference for parenteral or liposomal administration in therapeutic settings.

This information summarizes commonly discussed practices. IV administration is often combined with Vitamin C to prevent oxidation.

Glutathione is available as injectable solutions, oral capsules, and sometimes as part of compounded "drip" blends with vitamins and other agents.

Combination products should be evaluated for compatibility, indication, and cumulative risk.

Evidence spans basic science, small clinical trials, and cosmetic reports. Findings are context-specific and do not support broad claims of detoxification or anti-aging.

Future FAQs may address how glutathione supplementation compares with supporting endogenous antioxidant systems through lifestyle and established therapies. Answers will remain educational and non-prescriptive.
