Grape seed extract is often marketed for its potential anti-aging effects, primarily due to its high content of oligomeric proanthocyanidin complexes (OPCs), which are potent antioxidants. Scientific interest stems from the theory that oxidative stress and free radical damage contribute to cellular aging and the development of age-related diseases. Several in vitro and animal studies have shown that grape seed extract can reduce oxidative stress and inflammation, both of which are linked to aging processes.

However, while these mechanisms are well-supported in laboratory settings, robust clinical evidence in humans is limited. Some small-scale human trials have suggested improvements in skin elasticity and reduction of wrinkles, but these studies are often short-term, involve small sample sizes, or are funded by supplement manufacturers. Systematic reviews and meta-analyses generally conclude that, while grape seed extract is safe and demonstrates antioxidant activity, there is insufficient high-quality clinical evidence to confirm significant benefits for the prevention of aging or age-related decline in humans.

In summary, the use of grape seed extract for anti-aging purposes is grounded in plausible biological mechanisms and some preliminary clinical findings, but the overall quality and quantity of human evidence remain limited. Therefore, the scientific support for its use in aging prevention is weak to moderate at best.
