L-Glutathione is a naturally occurring antioxidant found throughout the body and plays an important role in protecting cells from oxidative stress. It contributes to the body's natural antioxidant defence system and helps maintain cellular balance. Glutathione also participates in the recycling of other antioxidants, including vitamins C and E, while supporting normal liver and cellular functions. Since glutathione levels can change with age and lifestyle factors, maintaining adequate levels is an area of ongoing nutritional research. Its role in antioxidant protection makes glutathione a valuable component of a daily wellness routine focused on cellular resilience and healthy aging.
