Many dietary supplements promise cell protection, but few actually deliver it in this quality. OPC, a highly effective plant compound derived from grape seeds, is among the most powerful naturally occurring antioxidants. Scientific studies show that its antioxidant effect significantly exceeds that of vitamin C. In some analyses, it's even 20 times greater. At Duma Nutrition, we focus on uncompromising purity. Our new OPC 300 contains exclusively pure grape seed extract from Spanish grapes, no grape seed flour, no fillers, and no artificial additives. Only what works, for those who consciously want to strengthen their health. Natural. Effective, and pure.
Why our grapes come from Spain - and it's no coincidence.
Our grapes come from select growing regions in Spain. Why? Because we find optimal conditions there: plenty of sun, few pollutants, and sustainable agriculture. According to a recent study, grapes from high altitudes in southern Spain contain up to 30% more OPC than those from cooler, damp regions. We believe that quality begins where the plant is at home. That's why we source our raw materials precisely where they naturally develop their highest potency.
OPC - The underestimated cell protection molecule with measurable effects on your health and performance
OPC is one of the most extensively studied phytochemicals, with exceptional antioxidant capacity, significantly higher than that of traditional vitamins. Scientific analyses show that OPC can neutralize oxidative processes directly at the cell membrane, up to 20 times more effectively than vitamin C. It not only protects cells but also supports their regeneration, a factor that is particularly crucial during periods of high physical or mental stress. In modern nutritional medicine, OPC is valued for its influence on vascular health, the immune system, and silent inflammation. Several recent studies underscore its positive effects on chronic inflammatory processes, skin structure, and microcirculation.
OPC 300 - What are the specific benefits for you?
High-performance cell protection: Studies show that OPC efficiently captures free radicals in areas where other antioxidants cannot reach (e.g., in the brain).
Increased performance & regeneration: Improved microcirculation provides better nutrition to your tissue. A real game changer for athletes and hybrid athletes.
Anti-aging: OPC protects collagen in the skin, blood vessels, and joints, resulting in fewer wrinkles, more elasticity, and noticeable firmness.
Inflammation inhibition at the cellular level: Recent publications show a significant reduction in inflammatory markers (e.g. CRP) with daily intake of 300 mg OPC.
Natural immune system upgrade: OPC strengthens the barrier function of your cells and even inhibits the spread of certain bacteria and viruses.
Our conclusion: OPC is not the same as OPC and that is exactly what makes the difference .
