Published in Journal of Hypertension
Methodology
Randomised placebo-controlled crossover trial of grape seed polyphenols in treated hypertensive adults measuring blood pressure and oxidative stress markers

Blood pressure benefits of grape seed extract are not consistent across all populations.
Limitations
Small crossover sample in already-treated hypertensives.
Supplements Studied
Grape seed polyphenols did not significantly lower blood pressure or oxidative stress markers compared with placebo.
