What Is Glutathione?

Glutathione (GSH) is a tripeptide molecule your body naturally produces — but levels decline with age, stress, illness, and environmental exposure. It's made of three amino acids working together:

Glu

Glutamic Acid

Supports brain function, immune response, and cellular energy production.*

Cys

Cysteine

The rate-limiting amino acid — determines how much glutathione your body can make.*

Gly

Glycine

Protects against oxidative stress and supports the body's detox pathways.*

Together, these three form L-Glutathione (Reduced) — the active, bioavailable form used in the Defender injection. Oral glutathione supplements are largely broken down in the gut before reaching cells. Injected directly, it bypasses digestion entirely.*
