Our red wine polyphenols extract powder is a concentrated source of bioactive compounds extracted from the skin of red grapes. It provides a potent blend of flavonoids, anthocyanins, and tannins designed to support cardiovascular health and fight oxidative stress.
The global market for red wine polyphenols is expanding rapidly, driven by demand for functional foods, dietary supplements, and cosmetics. Consumers increasingly seek natural antioxidants for anti-aging and inflammation management, making this high-purity powder a premium ingredient for global manufacturers.
Unlike standard suppliers with fixed concentrations, we offer customized polyphenol concentrations from 5% to 98% to meet specific formulation needs in nutraceuticals and high-end skincare.
Optimized through over 20 years of research, our process maximizes resveratrol (up to 5%) and proanthocyanidins (up to 90% OPCs), ensuring superior bioavailability.
Low residual solvents (tested <0.1ppm) meet USP/EP pharmaceutical grade standards. Sourcing directly from vineyards saves 15-20% in costs while maintaining high purity.
A dedicated production line handles everything from 5 kg trials to 100+ ton annual orders. Options include water-soluble versions for RTD beverages and organic certifications (EU/USDA).
