LongevityEndogenous antioxidant

The body's primary antioxidant, by injection.*

Glutathione is the body's master antioxidant, the molecule downstream of nearly every detoxification and aging pathway.

Quick read

What it is
A small protein made of three amino acids (cysteine, glycine, glutamic acid). The body's most-used antioxidant and central to phase II liver support.
Primary benefit
Supports the body's own antioxidant and detoxification systems, and supports liver function through the pathways the body already runs.
Mechanism
Buffers oxidative load at the cellular level and supports the phase II conjugation pathway the liver uses to process alcohol, medications, and environmental exposure.
Who it's for
Adults with high environmental load, hard training, elevated medication use, or anyone running a multi-compound longevity protocol who wants their antioxidant defense supported.

What it does

  • Liver support
    The liver's phase II conjugation pathway runs on glutathione. Restoring intracellular levels supports the pathway the body uses to process alcohol, medications, and environmental exposure.
  • Oxidative stress neutralization
    Free radicals get scavenged at the cellular level. Glutathione also recycles other antioxidants (vitamin C, vitamin E) so the broader defense system stays charged.
  • Immune modulation
    Lymphocyte function tracks closely with intracellular glutathione status. Patients running protocols for chronic inflammation or post-illness recovery use it for this lane.
  • Skin clarity
    A downstream effect of liver and inflammation work, not a topical action. Skin tone and clarity improvements show up at 6 to 12 weeks for most patients.

How it works

Glutathione is a tripeptide of cysteine, glutamate, and glycine the body produces to buffer oxidative load, recycle other antioxidants, and support phase II liver conjugation. Levels are depleted by stress, alcohol, medication load, environmental exposure, training volume, and age. Direct subcutaneous administration bypasses the oral bioavailability ceiling and supports the body's own antioxidant defense at the cellular level.
