Glutathione plays a central role in protecting cells from oxidative stressan imbalance between free radicals and antioxidants that accelerates cellular damage and drives forward the aging process across organs in the body. As Glutathione levels naturally decline with age, cells may become less equipped to neutralize free radicals and support cellular repair. Research suggests that maintaining healthy Glutathione levels may help support mitochondrial function, detoxifications, and immune resilience, all of which are relevant to skin health, energy, mental clarity, and healthy aging. Individual experiences vary and research is ongoing
