19,20 With aging, mitochondrial function declines, leading to decreased energy metabolism, increased ROS production, and the accumulation of mtDNA mutations, alongside the deterioration of other mitochondrial functions

Interestingly, the levels of glutathione and mitochondrial function, which were lower in older mice before taking GlyNAC, and oxidative stress, which was higher before GlyNAC, also were comparable to those found in younger mice after taking GlyNAC for six weeks
