Glutathione and hallmarks of aging: A study in older adults (n=48, aged 60-80) found that GlyNAC supplementation for 16 weeks improved several molecular hallmarks of aging, including mitophagy, nutrient sensing (reduced mTOR activation, increased AMPK signaling), inflammation (reduced NF-kB activation), and genomic instability (reduced 8-OHdG), alongside increased telomerase activity (Kumar et al., Aging, 2023) [31]
