Some followup comments that have emerged from a recent Rosacea News article on Grape Seed Extract + Vitamin C increases Blood Pressure. This article finished with the conclusion
Although the mechanism remains to be elucidated, these results suggest caution for hypertensive subjects taking supplements containing combinations of vitamin C and polyphenols.
A subsequent thread on The Rosacea Forum was wanting to downplay the significance of this study.
Some further comments from the Published Article’s Author:
The findings from our study were seen in treated hypertensives with additional cardiovascular risk factors. Although we don’t know the mechanism involved for the blood pressure increase, we are suggesting that people should use caution when considering taking these supplements. This research has been published in a peer-reviewed journal following a rigorous review process.

Are you saying if i take vitamin c and also take grape seed extract it will raise my blood pressure. When you say high vitamin c, what do you mean like 1000 mg or higher. Thanks, youe time appreciated.
Hi Dan, yes that is what the research is saying. I suggest that if you have concerns about mixing the two then perhaps the best advice you can get is from your doctor.
