What is Grape Seed Extract?
Grape seed extract is a concentrated source of oligomeric proanthocyanidins (OPCs), potent polyphenol antioxidants that protect blood vessels and collagen. Controlled trials show standardized grape seed extract can modestly lower blood pressure, improve circulation and vein health, and reduce oxidative stress, and it is also used for skin and eye support. Effects build over weeks. Standardize to 90 to 95 percent OPCs and dose around 100 to 300 mg daily. It is well tolerated, though like other polyphenols it has mild blood-thinning activity, so pause it before surgery and take care if you use anticoagulants.
