Outcome variables included activity of enzyme gelotatiun redoctase(GR), catalase (CAT) and superoxid dismutase (SOD) and abbreviated conners 10- item parent rating scale (CPRS), before and after supplementation. Results: After 8 weeks supplementation a significant difference was observed in activity of SOD, GR enzymes (P<0.05) but there was no significant difference between groups at activity of CAT at the end of intervention.
