Glutathione-SR 60cap - Thorne

Glutathione-SR 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 benefits of maintaining normal glutathione levels include supporting liver function, lung function, immune function, gut health, carbohydrate metabolism, cardiovascular health, cognitive health, and eye health.

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

Glutathione is the most abundant antioxidant. Because training and competition create more stress and oxidative damage, athletes have a greater need for antioxidants. Exercising for more than 60–90 minutes significantly decreases blood glutathione levels, so supplementation is beneficial for endurance and ultra-endurance events.

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

Maintaining optimal glutathione levels appears to be important for supporting cognitive function, especially during aging. The normal aging process is associated with a decrease in glutathione activity, which can result in increased oxidative activity. Less than optimal glutathione levels are seen in individuals who experience a decline in cognitive function. Conversely, individuals who live to 100 tend to have higher glutathione activity.

Although a common misconception is that glutathione is not well absorbed when taken orally, significant data confirm that glutathione is efficiently absorbed across the intestinal epithelium by a specific uptake system.

Because an athlete needs to know their supplements are reliable and compliant, every batch of an NSF Certified for Sport® product is tested for compliance with label claims and to ensure the absence of over 200 substances banned by many major athletic organizations, including stimulants, narcotics, steroids, diuretics, beta-2 agonists, and masking agents.
