Primary outcomePrimary: Endothelial Function — 11.7; 8.2 percent dilation
Summary
The purpose of this study is to investigate the impacts of a combined berry extract supplement (hawthorn berry, tart cherry, and bromelain extracts) on total antioxidant capacity, endothelial function, blood pressure, oxygen utility capacity, and fatigue index in healthy young adults.
