Plasma antioxidant markers in samples collected from 10 healthy subjects before (T0), 0.5 (T0.5), and 3 hours (T3) after the consumption of a single dose of two capsules of a green tea extract (GTE) supplement (200 mg × 2). UA: uric acid, FRAP: ferric reducing antioxidant potential, FRAP-UA: uric acid-independent FRAP, PLIR: peroxidation of leukocytes index ratio, L: lymphocytes, M: monocytes, and G: granulocytes. RM ANOVA, with time as within-subjects factor, followed by Student-Newman-Keuls post hoc analysis: T3 versus T0: .
