What this Trial Is About
Inflammation and stressors can interfere with the function of the lining of blood vessels and insulin activity, therefore, investigators are aiming to see how the Grape seed Extract (GSE) called MegaNatural BP can help with limiting the effects of these factors. This research will study the effects of taking 150mg of MegaNatural BP GSE per day on blood pressure levels along with influences on heart health through assessing the function of the blood vessel lining and levels of inflammation.
