After GlyNAC, older adults walked faster, had stronger grip strength, and improved endurance in the 6-minute walk test
Research also demonstrates that glutathione may improve blood circulation in patients with peripheral artery disease (x)
However, as discussed further below, redox potential may be a key factor in glutathione-dependent signaling, and so these tools are providing useful information in studies of mutants or responses to stress (Meyer et al., 2007
