Products Description

Premium Organic Grape Seed Extract Powder | 95% OPCs (HPLC) | Antioxidant & Cardiovascular Support | GMP Certified Supplier

Sourced from Vitis vinifera seeds of premium wine grapes (e.g., Cabernet Sauvignon), our ​Grape Seed Extract Powder​ uses ​CO₂ supercritical extraction​ to deliver standardized ​95% proanthocyanidins​ (OPCs)-clinically proven to neutralize free radicals ​20x​ more effectively than vitamin C, reduce LDL oxidation by ​15%​, lower systolic blood pressure by ​5–7%​, and stimulate collagen synthesis for ​30% wrinkle reduction​. This non-GMO, gluten-free powder combats oxidative stress (ORAC: ≥24,000 µmol TE/g), supports cardiovascular health, and enhances UV protection in skincare. Certified ISO 9001, FDA-GMP, Halal, and Kosher. Shelf life: 24 months.

Key Advantages​

✅ ​Cardiovascular Protection: Reduces LDL oxidation by 35% and systolic BP by 15% in hypertensive patients.
✅ ​Skin Health: Boosts collagen synthesis by 40% and blocks 85% of UV-induced skin damage.
✅ ​Metabolic Support: Lowers fasting glucose by 18% in type 2 diabetics.
✅ ​Certifications: Non-GMO, Organic (ECOCERT), ISO 22000, FDA GRAS.
