In human clinical use, reported side effects are generally mild and transient: Mild injection site redness or discomfort (resolves within hours) Transient nausea in some patients, particularly early in the protocol Mild dizziness or light-headedness (rare, typically dose-related) Temporary fatigue in the first few days (often a sign of active tissue remodeling) No significant systemic toxicity, organ damage, hormonal suppression, or addiction potential has been documented in the published literature
Typical applications include glutathione S-transferase phase-II conjugation assays, glutathione peroxidase and glutathione reductase coupled assays, GSH/GSSG ratio determination as a redox readout in cultured cells, protein S-glutathionylation studies, and ferroptosis models where glutathione availability governs glutathione peroxidase 4 activity and therefore phospholipid hydroperoxide handling (Yang et al., Cell, 2014)
Because it is found in nearly every cell in the human body, it serves as a primary defender against oxidative stress
