Results of correlation between peroxidase activity and reduced glutathione (GSH), oxidized glutathione (GSSG), reducing power (A.U.), and uric acid and correlation between uric acid and GSH, GSSG, and reducing power of elderly individuals from the NP and CET groups before (pre) and after 30 days (post) of daily supplementation with placebo or L-glutamine. Data were statistically analyzed using Pearson's correlation with a risk value of 5% (p < 0.05).
