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 an optimum level of glutathione is observed in individuals experiencing a decline in cognitive function.* Conversely, individuals who live to 100 tend to have higher glutathione activity.* Although a common mistaken belief is that glutathione is not well absorbed when it's taken orally, significant data confirms that glutathione is efficiently absorbed across the intestinal epithelium by a specific uptake system.* Because an athlete needs to know that his or her supplements are trustworthy and compliant, every batch of an NSF Certified for Sport product is tested for compliance with label claims and to ensure the absence of more than 200 substances banned by many major athletic organizations, including stimulants, narcotics, steroids, diuretics, beta-2 agonists, and masking agents
