Consequently, an extracellular cystine or intracellular cysteine deficiency or inhibition of system ( SLC7A11 ) would reduce the GSH level, inhibit GSH-dependent GPX4 activity, and lead to the intracellular accumulation of L-ROS and cell death (Dolma et al., 2003
NAC supplementation can lead to cysteine production and improved production of protective sulfane sulfur species and GSH
A meta-analysis of randomized controlled trials found that daily vitamin E supplementation equivalent to 25 to 536 mg/day of RRR --tocopherol for several years resulted in a significant, 10% reduction in the risk of ischemic stroke (five trials, 91,393 participants) and a nonsignificant trend towards an increased risk of hemorrhagic stroke (five trials, 100,748 participants) (120)
