Grape seed extract and vitamin C increase blood pressure
Nice find by David... Grape seed extract + vitamin C increases blood pressure. Quite a high supplementation with GSE (1000mg/day) but still, very much worth being aware of.
"A significant interaction between grape-seed and vitamin C treatments for effects on BP was observed"
...
"Conclusion: Although the mechanism remains to be elucidated, these results suggest caution for hypertensive subjects taking supplements containing combinations of vitamin C and polyphenols."
I know that many rosaceans are taking these supplements.
