Flavoenol® is the dry extract of grape seeds (Vitis vinifera L.) standardized in flavonoids, the largest class of soluble grape polyphenols. Grape seeds flavonoids are responsible for many biological activities as cardioprotective, anti-oxidant, anti-inflammatory, antimicrobial, antiviral and neuroprotective (1).
Grape seeds are particularly rich in oligomeric proanthocyanidins (OPC), strong antioxidants with healthy effects on cardiovascular system (2).

Cardiovascular protection
Several studies demonstred that the consumption of grape derived products can have beneficial effects on cardiovascular system by improving the vascular and endothelial function, reduction of LDL oxidation and the modulation of the serum lipids levels and inflammatory processes.
The action is principally due to the OPCs, able to enanche the endogenous antioxidants effectiveness in reducing lipid peroxidation and determining the reduction of atheromatous plaques (1, 3).
