What Is Glutathione?
Glutathione is a naturally occurring antioxidant composed of three amino acids: glutamine, cysteine, and glycine. It is produced within cells throughout the body and plays a central role in maintaining normal cellular function.
Researchers have long studied glutathione because of its involvement in antioxidant defense, cellular detoxification, oxidative stress, immune biology, and mitochondrial function. Since virtually every cell contains glutathione, it has become one of the most extensively researched molecules in cellular biology.
Current scientific interest focuses on how glutathione contributes to cellular resilience, redox balance, and normal metabolic processes.
