Glutathione

Featured

Also known as: GSH, L-Glutathione, Reduced Glutathione, Master Antioxidant

The body's master antioxidant for detoxification, immune function, and cellular protection.

Overview

Glutathione is a tripeptide (glutamate-cysteine-glycine) that serves as the body's primary intracellular antioxidant. It plays critical roles in detoxification, immune function, and protecting cells from oxidative damage. Levels decline with age and illness, making supplementation popular for anti-aging and detox.

Mechanism of Action

Directly neutralizes free radicals and reactive oxygen species. Conjugates with toxins for excretion via glutathione-S-transferase. Regenerates other antioxidants (vitamins C, E). Essential for immune cell function.

Pharmacokinetics

Poor oral bioavailability (broken down in gut). IV/IM provides direct delivery. Liposomal forms improve oral absorption.

Key Research Findings

  • 1Master antioxidant and detoxifier
  • 2IV form popular for skin lightening
  • 3Supports liver detoxification pathways
  • 4Declines significantly with age

Side Effects & Contraindications

Reported Side Effects

  • Zinc depletion (chronic use)
  • Bloating (oral)
  • Rare allergic reactions (IV)

Contraindications

  • Asthma (nebulized may trigger)
  • Sulfite sensitivity

Safety Considerations

Generally safe. IV can cause rare reactions. May lower zinc levels with chronic high doses. Skin lightening use controversial.

Storage Requirements

Refrigerate solutions, protect from light
