glutathione peroxidase reductase enzyme system Glutathione-Related Enzymes and Proteins: A Review The antioxidant enzymatic system is

At the same time, GSH is oxidized to GSH disulfide, which is then decreased back to GSH by nicotinamide adenine dinucleotide phosphate (NADPH)-dependent on GSH reductase to enter the next cycle

Vitamin C exerts immunomodulatory activity, enhancing interferon production through STAT3 phosphorylation (90), limiting cytokine-induced organ damage (55), promoting survival in lethal infections (54) and, importantly, is able to recycle oxidized quercetin (120), enhancing its antiviral effects
