01 / CLASSIFICATION

What is Glutathione?

Entity typeNative peptide

Research categoryOther

Known namesGlutathione, GSH

Editorial unitOne molecule or defined product record

Names, fragments, salts, formulations, routes, and branded products are kept distinct whenever transferring evidence would change the conclusion.

Goal: Redox & Skin Goal: Longevity Research

02 / EVIDENCE

Glutathione human and preclinical evidence.

HUMAN

3/5 · Route-specific human research

Oral and dermatologic studies exist, but results vary by outcome and cannot be transferred to intravenous or compounded sterile products.

PRECLINICAL

4/5 · Established redox biology

Glutathione is central to cellular redox biology; endogenous importance does not prove every supplementation claim.

The five-point bars describe the maturity and depth of the evidence base. They do not score effectiveness, safety, or personal suitability.

03 / STATUS

Glutathione FDA and sport status.

U.S. FDANo FDA-approved injectable glutathione drug product identified; FDA has reported adverse events linked to contaminated compounded sterile glutathione.

2026 WADANot specifically named in the 2026 WADA List; athletes should verify the complete formulation and current status.
