What is Grape Seed Extract?

Grape Seed Extract (GSE), derived from Vitis vinifera seeds, is a powerhouse of oligomeric proanthocyanidins (OPCs), a class of polyphenols renowned for their exceptional antioxidant properties. With ≥95% OPCs (verified by UV testing) and compliance with FDA, ISO 9001, and Halal certifications, our GSE is a versatile ingredient for nutraceuticals, cosmetics, functional foods, and pharmaceuticals. Sourced from sustainably farmed grapes in China and Europe, it offers unmatched purity and bioavailability.

Key Benefits & Applications

1. Superior Anti-oxidant Raw Material
• 50x stronger than Vitamin E, 20x stronger than Vitamin C in neutralizing free radicals, protecting cells from oxidative stress linked to aging, cardiovascular diseases, and neurodegenerative disorders.
• Crosses the blood-brain barrier (BBB): Protects neurons, reduces neuroinflammation, and enhances cognitive function, validated by studies in Frontiers in Pharmacology.
2. Skin Health & Anti-aging And Anti-wrinkle Raw Materials
• UV protection: Shields skin from 85% of UV-induced damage by preserving collagen and elastin integrity.
• Reduces hyperpigmentation and wrinkles: Inhibits tyrosinase activity, promoting even skin tone and elasticity.
3. Cardiovascular & Metabolic Health
• Lowers blood pressure and cholesterol: Improves endothelial function and reduces arterial plaque formation, as shown in clinical trials.
• Anti-inflammatory effects: Mitigates chronic inflammation associated with arthritis and autoimmune conditions.
4. Industrial Applications
• Food Additives& Beverage: Natural preservative and antioxidant in functional foods, beverages, and baked goods.
