Metabolic and Immune Support Beyond its antioxidant role, glutathione is necessary for healthy carbohydrate metabolism and is involved in metabolizing insulin and regulating blood glucose levels already in the normal range

When NRX is oxidized by NADPH oxidase 1 (NOX1)-derived H2O2 or lipid peroxide (ROOH), DVL is released and inhibits glycogen synthesis kinase 3 (GSK3) in the -catenin degradation complex, thereby stabilizing the -catenin in the cytoplasm and partially entering the nucleus to activate the target gene GPX2 by correlation with the TCF/LEF transcription factor family (Kipp et al., 2012) (Figure 2)
