Quercetin Lowers Blood Pressure

The double-blind, placebo-controlled, crossover study found that subjects who took 730 mg of quercetin daily enjoyed blood pressures that were 7 mm/Hg lower for systolic (upper number) and 5 mm/Hg lower for diastolic (lower number) after just 28 days.

Dr. Ray Hinish’s Notes:

Quercetin is a bioflavonoid that is most commonly used in the management of allergies, although it is well known for many other benefits to the body. This appears to be the first study to demonstrate benefit to blood pressure. It is very interesting that blood pressure came down despite the normal blood pressure of the participants of the study. The dose of quercetin used in the study was quite conservative, the dose used in management of allergies is typically 1500 – 2500 mg daily.
