Summary

This study tests whether eating wild blueberry powder every day can lower blood pressure and improve blood vessel health in middle-aged and older men and postmenopausal women with slightly high blood pressure. Researchers will measure artery function and stiffness over time. The goal is to see if this simple dietary change can help prevent heart disease.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
wild blueberry powder
What this could lead to
If it works, this could point toward a simple dietary supplement to help manage blood pressure and reduce heart disease risk.
What could go wrong
This is an early-phase trial with only 58 participants, so results may not apply widely. The effect may be small or no better than placebo.
