Benefits
Cognitive support
Grape seed proanthocyanidins are studied for supporting cognitive function and protecting the brain from oxidative stress.
Antioxidant defense
Grape OPCs are potent antioxidants that protect neurons and blood vessels from free-radical damage.
Brain blood flow
By supporting healthy blood-vessel function, grape polyphenols support circulation to the brain.
Mechanism of action
Proanthocyanidin neuroprotection
Grape OPCs scavenge free radicals and support antioxidant defenses in brain tissue, protecting neurons from oxidative stress.
Vascular support
Grape polyphenols support nitric-oxide-mediated blood-vessel relaxation, aiding blood flow to the brain.
Clinical trials
Study of a grape seed proanthocyanidin extract on oxidative stress and vascular markers. (Kalin et al. 2002, Free Radical Research)
Adults.
The grape proanthocyanidin extract reduced markers of oxidative stress and vascular inflammation, relevant to neuroprotection.
