Glutathione-SR represents a significant advancement in glutathione supplementation, thanks to its sustained-release formula that shields it from stomach acid and digestive enzymes. This innovative design ensures a slower, more consistent release, maintaining steady levels of this vital antioxidant in the bloodstream. As the body's most abundant antioxidant, glutathione becomes even more critical for athletes, whose training and competition intensify oxidative stress and damage. Endurance activities lasting longer than 60-90 minutes can significantly deplete blood glutathione levels, making this supplement especially beneficial for those aiming to optimise performance and recovery.
