Benefits
Antioxidant defense
Grape seed OPCs are highly potent antioxidants that help protect cells and blood vessels from oxidative stress.
Vascular and cardiovascular support
OPCs support healthy blood-vessel function and circulation, contributing to cardiovascular health.
Menopausal support
In a randomized controlled trial, grape seed proanthocyanidin extract supported improvements in menopausal symptoms and body composition in middle-aged women.
Mechanism of action
Proanthocyanidin antioxidant action
OPCs neutralize free radicals and support the body's antioxidant enzymes, protecting blood vessels and tissues.
Endothelial support
Grape seed polyphenols support nitric-oxide-mediated blood-vessel relaxation and healthy circulation.
