Glutathione Spray

Glutathione Spray is supplied as a pre-dissolved, sterile-filtered solution in amber glass bottles fitted with a metered atomizer, at 600 mg or 1,500 mg per unit. Nitrogen purging matters more for this compound than for anything else in the catalog: the free cysteine thiol oxidises to the disulfide dimer on contact with atmospheric oxygen, and that conversion begins within minutes of opening a powder vial. Supplying it pre-dissolved under nitrogen removes the highest-risk handling step entirely.

Store Glutathione Spray refrigerated at 2°C to 8°C (36°F to 46°F), upright and protected from light, where sealed units remain within specification for up to 24 months. Once the atomizer is first actuated, use the unit within 30 days and minimise air exposure at every step. Oxidation, not hydrolysis or aggregation, is the limiting stability factor here, and each opening admits oxygen that converts reduced glutathione to the inactive disulfide form. Avoid contact with trace metal ions, which catalyse that oxidation. Brief transit excursions to 15°C to 25°C (59°F to 77°F) are tolerated.

Glutathione is a tripeptide with an unusual bond that defines its behaviour. Its glutamate residue joins the cysteine through the side-chain carboxyl rather than the normal backbone linkage, and that gamma-glutamyl bond is why ordinary peptidases cannot cleave it, giving the molecule an intracellular lifetime no conventional tripeptide would have. The cysteine thiol does the chemical work. Glutathione peroxidase consumes two molecules to reduce a peroxide, generating the oxidised disulfide dimer, and glutathione reductase then regenerates the reduced form using NADPH, so the pair cycles continuously. The same thiol serves as the conjugating nucleophile for glutathione S-transferase enzymes. Research shows the ratio between reduced and oxidised forms is the standard quantitative index of cellular redox state.

Yes. Qualified procurement partners can request alternative concentrations, non-standard bottle volumes, unlabeled or private-label presentation, or co-formulation with complementary antioxidant research compounds such as L-Carnitine. Contact our corporate sales desk with your target concentration and unit count to scope the run.

Units ship in light-blocking, vacuum-sealed secondary packaging with temperature-stability buffers that hold the shipment inside the refrigerated range through transit. Amber primary containers and nitrogen-purged headspace protect the free cysteine thiol against air oxidation. We ship nationwide across all 50 US states and internationally via express couriers with discrete, border-optimized clearance and full delivery assurance.
