Thorne's Glutathione is NSF Certified for Sport.   

It occurs naturally in cells and is a cofactor in dozens of enzymatic reactions involved in detoxification.  As an antioxidant, glutathione directly quenches several reactive oxygen species (free radicals).  The body's benefits from maintaining a normal level of glutathione include support for liver function, pulmonary function, immune function, bowel health, carbohydrate metabolism, cardiovascular health, cognitive health, and eye health. 

Glutathione-SR is a breakthrough in glutathione supplementation because its sustained-release formula protects it from stomach acid and digestive enzymes, allowing for a slower release and a more steady level in the bloodstream of this essential nutrient. 

Glutathione is the most abundant anti-oxidant. Since training and competition create more oxidative stress and damage, athletes have a higher need for antioxidants. Exercise longer than 60-90 minutes significantly decreases glutathione levels in the blood, so supplementing is beneficial for endurance and ultra endurance events.

The liver is the body's largest reservoir for glutathione. A potent endogenous antioxidant, glutathione is essential for the liver's phase I and phase II detoxification.* However, negative lifestyle issues and adverse conditions that affect liver health can result in a decreased amount of glutathione in the liver.
