About





            

                
Quercetin is a ubiquitous dietary flavonoid that reduces blood pressure through endothelium-dependent nitric oxide release and ACE inhibition. A 2020 meta-analysis of 17 RCTs found quercetin at >=500 mg/day reduced systolic blood pressure by 3.09 mmHg and diastolic by 2.86 mmHg, with greater effects in hypertensive subjects.

            

        

        

        
        
        

            

  
How It Works





            

                
Inhibits LDL oxidation and foam cell formation; reduces blood pressure through direct vasorelaxation via endothelium-dependent nitric oxide release; inhibits ACE activity; anti-inflammatory via NF-kB, COX-2, and lipoxygenase inhibition; reduces platelet aggregation; may inhibit PCSK9 expression reducing LDL receptor degradation.
