Feringa HH, Laskey DA, Dickson JE, Coleman CI
Published in Journal of the American Dietetic Association
Methodology
Meta-analysis of 9 randomised controlled trials of grape seed extract on blood pressure, heart rate and lipids
Key Findings
Grape seed extract significantly lowered systolic blood pressure by 1.54 mmHg and heart rate by 1.42 bpm, with no significant effect on lipids or C-reactive protein.
Conclusions
Grape seed extract produces small blood pressure reductions but does not improve lipid profiles.
Limitations
Small trials with heterogeneous preparations and doses.
Supplements Studied
Grape seed extract significantly lowered systolic blood pressure and heart rate but had no effect on lipid levels or C-reactive protein.
Outcomes Measured
Grape seed extract significantly lowered systolic blood pressure and heart rate.
Grape seed extract significantly lowered systolic blood pressure by 1.54 mmHg and heart rate by 1.42 bpm, with no significant effect on lipids or C-reactive protein.
