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:
Glutamic Acid
Supports brain function, immune response, and cellular energy production.*
Cysteine
The rate-limiting amino acid — determines how much glutathione your body can make.*
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.*
What Glutathione Does for Your Body
- Neutralizes free radicals — directly scavenges oxidative molecules that damage cells and accelerate aging*
- Supports immune defense — helps regulate immune cell activity and protects white blood cells from oxidative damage*
- Liver detoxification — binds to toxins, heavy metals, and harmful compounds for safe elimination*
- Skin brightening & radiance — inhibits melanin production at the cellular level, supporting an even, luminous complexion*
- Reduces inflammation — lowers oxidative stress markers linked to chronic inflammation throughout the body*
- Supports mitochondrial health — protects the energy-producing centers of your cells from oxidative damage*
- Anti-aging at the cellular level — slows cellular aging by protecting DNA from oxidative damage*
