What Is Glutathione?

Glutathione is a naturally occurring tripeptide made from glutamate, cysteine, and glycine. It is one of the body's major intracellular antioxidants and participates in redox balance, detoxification pathways, and immune-related cellular functions. It is not a peptide hormone, and injectable glutathione for cosmetic or wellness purposes is not FDA-approved.

How It Works

Glutathione helps buffer oxidative stress and supports cellular antioxidant systems. It is also involved in detoxification reactions and maintaining redox balance. Glutathione is not described as a guaranteed detox, disease treatment, or safe injectable skin-lightening product.

What It’s Studied For

Glutathione has been studied as an antioxidant, in nutritional support contexts, and in dermatology/cosmetic contexts such as pigmentation. Evidence varies by route: oral, topical, inhaled, and IV/injectable use have different risks and data. FDA has raised concerns with glutathione compounded into sterile injectables after adverse events associated with endotoxin contamination.

How It May Be Used in a Clinician-Supervised Program

A licensed clinician may consider glutathione support after reviewing oxidative-stress-related goals, liver/kidney status, asthma history, allergies, pregnancy/breastfeeding status, current medications, and whether non-injectable options are more appropriate. It is not positioned as a disease treatment or guaranteed detox.

Preferred Starting Options / Dosing Notes

Many patients begin with a lower starting option so a licensed clinician can evaluate tolerance, medical history, goals, and safety factors before any adjustments are considered. The starting option shown below is informational and reflects available program data, not self-directed dosing instructions. Final medication, dose, frequency, and treatment plan are determined by a licensed clinician.

Safety Considerations

• Possible allergic reactions and asthma-related concerns for some routes.
• Injection/infusion reactions and contamination/endotoxin risks with sterile compounding.
• Lack of long-term safety data for chronic IV use in cosmetic contexts.
• Skin-lightening claims are avoided; FDA safety concerns apply to injectable compounding.

Some treatments may involve compounded medications when prescribed by a clinician. Compounded medications are not FDA-approved. The FDA does not evaluate compounded medications for safety, effectiveness, or quality before marketing.
