Grape seed extract, typically standardized to contain oligomeric proanthocyanidins (OPCs), is one of the more well-studied herbal supplements thanks to its potent antioxidant profile. Research suggests that OPCs may help support cardiovascular health by promoting healthy blood pressure levels, improving circulation, and assisting with cholesterol management, with several clinical trials showing modest but meaningful benefits in these areas. Studies also indicate potential roles in reducing oxidative stress, supporting skin elasticity and resilience against UV damage, and contributing to eye health by strengthening capillaries and improving blood flow to ocular tissues. Its broad anti-inflammatory and antioxidant properties have made it a popular choice for those interested in general wellness support, though individual responses can vary.
