The present study investigated whether a quercetin supplement could reduce various risk factors for cardiovascular disease. For this purpose, 93 overweight or obese subjects with metabolic syndrome (simultaneous occurrence of several cardiovascular risk factors) were studied who supplemented their diet with quercetin for 6 weeks. The final results showed that dietary supplementation contributed to significant improvement in LDL cholesterol and systolic blood pressure in the participants. Further details can be found in the study.
