However, increasing evidence indicates that EGCG produces ROS. Aim of the study: Evaluate DNA damage and oxidative damage, measured by comet assay; lipid profile, liver function parameters, and vitamins A and E levels during an interventional study with 90 days (T0 and T90) duration (T0 and T90) in 30 individuals with an EGCG intake of 225 mg/day.engDNA damageOxidative damageGreen teaEpigallocatechin-3-gallateFCT_UIDP/05608/2020FCT_UIDB/05608/2020conference poster
