It occurs naturally in cells and is a cofactor in dozens of enzymatic reactions involved in detoxification.* As an antioxidant, glutathione directly quenches several reactive oxygen species (free radicals).* The body's benefits from maintaining a normal level of glutathione include support for liver function, pulmonary function, immune function, bowel health, carbohydrate metabolism, cardiovascular health, cognitive health, and eye health.* Glutathione-SR is a breakthrough in glutathione supplementation because its sustained-release formula protects it from stomach acid and digestive enzymes, allowing for a slower release and a more steady level in the bloodstream of this essential nutrient.*Glutathione is the most abundant anti-oxidant

Concurrently, impaired function of regulatory receptors, such as triggering receptor expressed on myeloid cells 2 (TREM2), reduces phagocytic clearance and attenuates anti-inflammatory signaling, thereby impairing endogenous resolution pathways (Ajoolabady et al., 2025)
Intranasal administration delivers the peptide efficiently to central nervous system targets, though peripheral effects on neurotrophic factor production may also benefit peripheral nerve health indirectly
However, it can take 3-6 months to fully recover
