Redox parameters assessed in whole-blood cells of participants in the placebo and supplement groups before and after the treatment. (A) Glutathione reductase activity (mU GR/mg protein). (B) Glutathione peroxidase activity (mU GPx/mg protein). (C) Concentration of reduced glutathione (nmol GSH/mg protein). (D) Concentration of oxidized glutathione (nmol GSSG/mg protein). (E) GSSG/GSH ratio. (F) Thiobarbituric acid-reactive substance concentration (nmol TBARs/mg protein). * p < 0.05, ** p < 0.01, and *** p < 0.001 compared to the initial condition. GR: glutathione reductase activity; GPx: glutathione peroxidase activity; GSSG: oxidized glutathione; GSH: reduced glutathione; and TBARs: thiobarbituric acid-reactive substances.
