Quercetin and Vitamin C Supplementation: Effects on Lipid Profile and Muscle Damage in Male Athletes
Background : Quercetin , which is considered as a health-promoting antioxidant , belongs to the broad flavonoids group . Numerous experimental studies have proved that quercetin and vitamin C provide anti-inflammatory and antioxidant properties . The aim of this study is to assess the effects of both quercetin and vitamin C on lipid profile and muscle damage in human subjects . Methods : A r and omized , placebo-controlled , double-blind clinical trial was carried out on 60 males for eight weeks . The subjects were r and omly assigned to one of the four groups : 1 ) quercetin + vitamin C ( 500 mg/day quercetin + 200 mg/day vitamin C ) 2 ) quercetin ( 500 mg/day quercetin + 200 mg/day placebo ) 3 ) vitamin C ( 500 mg/day vitamin C + 200 mg/day placebo ) and 4 ) placebo ( 500 mg/day placebo + 200 mg/day placebo ) . Blood sample s , body weight and percent of body fat were measured before and after intervention . In addition , dietary intake was estimated using 24-h recall . Results : No significant changes occurred in high-density lipoprotein levels between groups and in the four groups before and after supplementation . Low density lipoprotein values decreased significantly ( P = 0.048 ) in the “ Quercetin + Vit C ” group but decrease was not considerable in other groups before and after intervention and among groups . Fat-soluble vitamins ' intake was significantly high among 4 groups . Conclusions : Quercetin and vitamin C supplementation may not be beneficial in lipid profile improvement , although it may reduce induce muscle damage and body fat percent
