FIG. 5. — Changes in the plasma TGF-β levels pre- and post-GSH supplementation. Sandwich enzyme-linked immunosorbent assay (ELISA) was performed to compare the cytokine levels between pre-supplementation (V1) and post-supplementation (V3). Assay of cytokines showed a significant decrease in the levels of TGF-β in plasma samples collected from the liposomal GSH (lGSH)-treatment group after 13 weeks of supplementation. There was no significant difference between the levels of TGF-β from the placebo group when comparing visit 1 and visit 3 (A). Data represent mean±SE, *P<0.05 when comparing pre- and post-supplementation levels within placebo or lGSH group. GSH assay was performed to compare the levels of total GSH between pre-supplementation (V1) and post-supplementation (V3). Assay of GSH showed a significant increase in the levels of total GSH in PBMCs of the lGSH-treatment group after 13 weeks of supplementation. There was no significant difference between the levels of total GSH from the placebo group when comparing visit 1 and visit 3 (B). Data represent mean±SE, *P<0.05 when comparing pre- and post-supplementation levels within placebo or lGSH group.
