glutathione or nac better vs. NAC: An Expert Comparison of Antioxidants – Transparent Labs N-Acetyl Cysteine (NAC) is a

By binding copper(II) ions, it helps regulate gene expression linked to collagen formation, angiogenesis, antioxidant defense, and tissue remodeling. The peptides small size allows it to penetrate tissues efficiently, and its copper-transfer activity underlies its reported effects on skin, hair, and wound-healing processes in laboratory models

Glutathione injections are used clinically to support antioxidant capacity, particularly when oral absorption may be limited, and off label to help improve liver function
