Oxidative Medicine and Cellular Longevity, Volume 2021, Issue 1, 2021., 2021 The current work was aimed at evaluating the ameliorative role of quercetin (QR) on the possible toxicity of Red Bull energy drink (RB‐Ed) in the cerebral cortex of rats. To achieve the goal, the rats were allocated into 4 groups. The first group received distilled water as control.
