Advanced antioxidant support
Glutathione acts as a cofactor in dozens of enzymatic reactions involved in detoxification and cellular defense.* It directly neutralizes reactive oxygen species and helps maintain normal antioxidant balance throughout the body.*

Liver and detox support
The liver is the body’s primary reservoir for glutathione. Adequate levels are essential for both Phase I and Phase II detoxification pathways.* Lifestyle stressors and environmental exposures can reduce glutathione availability, making supplementation beneficial.*

Support for athletes and endurance training
Intense and prolonged exercise increases oxidative stress and can significantly lower glutathione levels, especially during endurance activity lasting longer than 60–90 minutes.* Maintaining healthy glutathione levels supports recovery and overall performance resilience.*

Cognitive and healthy aging support
Normal aging is associated with reduced glutathione activity, which may contribute to increased oxidative stress.* Higher glutathione activity has been associated with preserved cognitive function and healthy aging.*

Trusted absorption
Despite common misconceptions, research confirms that orally administered glutathione is effectively absorbed through a specific intestinal transport system.*
