Glutathione
GSHMaster antioxidant tripeptide.
Also known as: GSH, L-Glutathione
Overview
Glutathione is an endogenous tripeptide regarded as the body's master antioxidant, studied extensively in redox-balance, detoxification, and cellular-protection research.
The body's master endogenous antioxidant — a tripeptide of glutamate, cysteine, and glycine central to redox balance, detoxification, and immune function. Levels decline with age and oxidative stress, driving research interest in supplementation for longevity and cellular protection.
Neutralizes reactive oxygen species and supports phase-II detoxification through its reactive thiol group and redox cycling.
Molecular information
γ-Glu-Cys-GlyFeatures an unusual gamma peptide bond; the reduced (GSH) form is the active antioxidant.
Pharmacokinetics

Observed effects timeline
Aggregated observations reported across research literature. Timing and magnitude vary by model and are not a guarantee of outcome.
Acute
Systemic antioxidant capacity and detox-pathway support reported after dosing.
Week 2–8
Skin-brightening and oxidative-stress-marker changes reported with consistent use.
Research compatibility
Describes how compounds are studied alongside one another in the literature. Not a recommendation to co-administer.
NAD+
Complementary cellular-energy/redox support.
SS-31
Complementary mitochondrial-antioxidant pathways.
Vitamin C
Often co-administered to support glutathione recycling.
How to reconstitute
Glutathione is light- and oxygen-sensitive. Reconstitute gently, protect from light, and use promptly once prepared.
- 1Allow the vial to reach room temperature (15–20 minutes).
- 2Swab the stopper with alcohol and let it air dry.
- 3Add the diluent slowly down the vial wall.
- 4Swirl gently until dissolved into a clear solution.
- 5Refrigerate at 2–8 °C, protect from light, and use promptly.
Quality indicators
Uniform white powder
Lyophilized cake should be white without yellowing (yellowing suggests oxidation).
Clear solution
Reconstitutes to a clear, colorless, particle-free solution.
Light protection
Highly sensitive to light and oxidation — keep covered and cold.
Slight clumping
Small clumps that dissolve completely with gentle swirling are acceptable — shipping can cause minor compaction.
Collapsed or melted appearance
Powder that looks collapsed, melted, or stuck to the vial walls may have been exposed to heat in transit.
Cloudy after reconstitution
Persistent cloudiness, particles, or precipitate after gentle mixing can indicate a degraded or contaminated peptide.
Reported observations & safety
Safety signals reported in the research literature. Compiled for scientific awareness — not medical advice.
- Generally reported as well tolerated; IV administration carries the usual infusion-related considerations.
- Among the best-established compounds in this list, with a long clinical and nutritional history.
