Supplementation With Quercetin May Help Support Healthy Blood Pressure

Quercetin is a flavonol that is found in grapes, berries, apples, citrus fruits, onions, broccoli, red wine, and black tea. Quercetin has antioxidant and anti-inflammatory properties. According to a recent study, supplementation with quercetin may help support healthy blood pressure levels.

For their study, researchers from Southern Medical University in China reviewed 17 clinical trials that included 886 participants. The trials looked at the effect of quercetin supplementation on plasma lipid profiles, blood pressure, and glucose levels.

The researchers found that quercetin supplementation reduced systolic blood pressure by an average of 3.09 mmHg and reduced diastolic blood pressure by an average of 2.86 mmHg. No effects were seen on plasma lipid profiles or glucose levels. However, in trials where participants consumed quercetin for 8 weeks or more, significant reductions were seen in LDL cholesterol and triglyceride levels.

The study was published online ahead of print on January 6, 2020 in the journal Nutritional Reviews.
