Glutathione occurs naturally in all human cells and is a cofactor for dozens of enzymes involved in detoxification.* As an antioxidant, glutathione directly quenches several reactive oxygen species (free radicals).* Numerous structures and functions in the body receive benefit from maintaining a normal level of glutathione, such as hepatic support, pulmonary health, immune function, bowel health, carbohydrate metabolism, cardiovascular health, cognitive health, and eye health.*
The liver is the body’s largest reservoir for glutathione. A potent endogenous antioxidant, glutathione is essential for phase I and phase II liver detoxification.* Unfortunately, lifestyle issues and conditions that negatively affect liver health can result in a decreased amount of liver glutathione.
Maintaining an optimal level of glutathione appears to be important for supporting cognitive function, especially during aging.* The normal process of aging is associated with a decrease in glutathione activity, which can result in increased oxidative activity.* Less than optimum levels of glutathione are observed in individuals experiencing a decline in cognitive function.* Conversely, individuals living over 100 years tend to have higher glutathione activity.*
A common mistaken belief is that glutathione is not well absorbed when it's taken orally, but significant data confirms it is efficiently absorbed across the intestinal epithelium by a specific uptake system.*
Glutathione-SR represents a breakthrough in glutathione supplementation. Absorption of oral glutathione can be impacted by stomach acid or enzymes in the duodenum, which can break down glutathione into its amino acid components. However, the sustained-release form of Glutathione-SR protects it from stomach acid and digestive enzymes, allowing for slower release and a more steady level in the blood of this essential nutrient.*
