Evaluation of Quercetin in Type 2 Diabetes: Impact on Glucose Tolerance & Postprandial Endothelial Function

This study is no longer recruiting particiapants.

A natural remedy to help lower blood sugar?

  • Are you 18-75 years old?
  • Do you have type 2 diabetes?
  • **New recruitment range!** Is your hemoglobin A1C between 6.5-10.5%?
  • Are you free from severe liver, kidney or heart disease?
  • Are you willing to stay on your current medications and supplements for one month prior and during the length of the study?

If yes, you maybe interested in participating in Bastyr University’s research study on the natural supplement quercetin. Quercetin is found naturally in fruits and vegetables like apples, onions and grapes.  Does it help lower your blood sugar?

We want to measure the effect of quercetin on your blood sugar and blood flow. We will be looking for 20 volunteers with type 2 diabetes for this study. If eligible, each volunteer will be asked to commit to three office visits within a one- or two-month period at the Bastyr Center for Natural Health in Seattle. You will receive a single dose of either a placebo, a nutritional supplement, or a pharmaceutical at each of these three visits.
