Glutathione (GSH) is a ubiquitous intracellular antioxidant involved in redox balance, detoxification, and immune function. While oral precursors and oral GSH can raise body stores in some studies, the clinical outcomes of injectable GSH vary by indication.

Check eligibility

Compounded injectable glutathione is not FDA-approved; regulators have warned of safety issues (e.g., endotoxin contamination) in some compounded lots. Glutathione is not FDA-approved to diagnose, treat, cure, or prevent any disease or medical illness.

Why it works

Key benefits

Adjunctive reduction of cisplatin-related neuropathy/ototoxicity in oncology settings (select trials)

Antioxidant support in research on neurodegenerative conditions (pilot trials)

General wellness support and cellular protection against oxidative stress

Context-specific, limited evidence

Mechanism

How it works

GSH directly participates in peroxide detoxification and regenerates other antioxidants. In specific clinical contexts, IV GSH has been studied as an adjunct to mitigate chemotherapy-induced neurotoxicity and as an exploratory agent in Parkinson’s disease; results are mixed and studies are small or heterogeneous.

Frequently asked questions

FAQs

Perceived effects are variable and indication-dependent. Any symptomatic changes are typically subtle and may require multiple sessions in protocolized settings.
