What Is Glutathione, Cysteine & C?

Life Extension's Glutathione, Cysteine & C combines three of the body's most powerful immune-supporting and antioxidant compounds in a single, synergistic formula. Glutathione — often called the "master antioxidant" — is found in every cell of the body and plays a central role in detoxification, immune defense, and cellular protection. This formula pairs it with L-cysteine and vitamin C to maximize glutathione production and stability.

Key Benefits

  • Immune support – Glutathione and vitamin C are essential co-factors in a robust immune response
  • Master antioxidant defense – Glutathione neutralizes free radicals and regenerates other antioxidants like vitamins C and E
  • Cellular detoxification – Supports the liver’s ability to neutralize and eliminate toxins and heavy metals
  • Skin health – Antioxidant activity helps protect skin cells from oxidative stress and supports a healthy complexion
  • Respiratory health – L-cysteine is a precursor to glutathione and supports healthy lung tissue
  • Longevity & healthy aging – Declining glutathione levels are associated with aging; supplementation helps maintain youthful cellular function

What Makes It Different?

Glutathione is notoriously difficult to absorb when taken alone — digestive enzymes break it down before it reaches the bloodstream. This formula takes a smarter approach: by combining glutathione with L-cysteine (its rate-limiting amino acid precursor) and vitamin C (which stabilizes and recycles glutathione), the formula supports both direct replenishment and endogenous production for sustained antioxidant activity.

Who Should Take This?

  • Adults looking to strengthen immune defenses year-round
  • Those exposed to environmental toxins, pollution, or heavy metals
  • Individuals seeking antioxidant support for healthy aging and cellular protection
  • Anyone with liver health concerns or detoxification goals
  • People wanting to support skin clarity and a healthy complexion from within
