However, preclinical research may only sometimes pan out in human studies
Aging (Reduced Synthesis Capacity) As you age, production of glutathione declines due to: Reduced activity of gamma-glutamylcysteine ligase (GCL) , the rate-limiting enzyme in glutathione synthesis Decreased cellular energy (ATP) to fuel glutathione recycling Lower levels of precursor amino acids (especially cysteine and glycine) Studies show glutathione levels drop 10-15% per decade after age 40 [3]

Additionally, these compounds pose great ecological risks as they commonly enter aquatic ecosystems where they persist in the environment and bioaccumulate in aquatic organisms 4
Moreover, it has also been demonstrated that NF-kB pathway is associated with apoptosis, causing the activation of genes linked to anti-apoptosis through target genes, which results in apoptosis escape and reducing drug efficacy
