A controlled and double blinded trial was performed to evaluate the effects of OPE supplementation on blood circulation in healthy male smokers. The study population consisted of 92 healthy male smokers aged 44.4±7.8 years. The supplement group (n=49) received OPE containing 100 mg quercetin/day for 10 weeks, while the control group (n=43) received placebo powders. The prothrombin time and activated partial thromboplastin time increased significantly after OPE consumption, indicating the attenuated blood clot formation by OPE. In conclusion, these results indicate that the daily consumption of OPE (containing 100 mg quercetin) for 10 weeks exerts significant health benefits through the modulation of physiological functions including the blood circulation in male smokers.
