High Quality Grapeseed Grape Proanthocyanidins Procyanidin OPC Powder 95% Grape Seed Extract

• Stable 95% OPC High Purity with Full HPLC Batch Detection

  We adopt high-performance liquid chromatography to test every batch to lock proanthocyanidin content steadily at 95%, much higher than common 30%-80% grape seed extracts on the market. Complete third-party test reports are provided for all bulk orders. Over 99.7% of finished batches pass independent laboratory audits, allowing manufacturers to control formula dosages accurately and guarantee consistent antioxidant efficacy of end products.

• Low-Temperature Supercritical CO₂ Extraction Preserves Active Ingredients

  We use supercritical carbon dioxide extraction operated under 38°C low temperature to avoid thermal decomposition of OPC molecules. Compared with traditional ethanol hot reflux extraction, this technology retains over 96% natural bioactivity of procyanidins, with no residual toxic solvents. The extract maintains stable antioxidant performance without activity loss during long-term sealed storage.

• Strict Raw Material Selection & Multi-Round Safety Inspection

  All grape seeds are sourced from pesticide-free vineyards with non-GMO certification, sorted twice to remove moldy, broken and immature seeds. Each batch undergoes 260+ tests covering heavy metals, pesticide residues and microorganisms, fully meeting EU and FDA standards. Heavy metal content is 10 times lower than international limit values, eliminating safety risks for long-term oral and topical use.

• GMP Dust-Free Production Line with Stable Bulk Export Capacity

  Our 4500㎡ GMP standardized extraction workshop is equipped with 5 full-automatic extraction and purification lines, achieving a monthly output of 20 tons of grape seed extract powder. We keep 3 tons permanent safety stock to support sample trial orders and full-container shipments. We have cooperated with more than 500 brands across 40+ countries for 9 years with zero major quality complaints.

• Ultra-Fine Micronized Powder with Excellent Dissolubility

  The finished extract is crushed into 120-mesh ultra-fine powder via low-temperature micronization treatment. It dissolves rapidly in water, ethanol and powder mixtures without caking or sediment, blending evenly with other plant extracts, vitamin powders and cosmetic substrates. It simplifies production mixing processes and ensures uniform color and efficacy of finished goods.

• Oral Anti-Aging Antioxidant Health Supplements

  This 95% OPC grape seed powder is the core raw material for antioxidant capsules, anti-aging tablets and beauty oral gummies. Its high-concentration procyanidins neutralize free radicals, delay skin aging and improve capillary circulation. Nutrition brands launch beauty and anti-oxidation supplement lines targeting female consumers, sold in pharmacies, health stores and cross-border e-commerce platforms.

• Functional Solid Drinks & Meal Replacement Blends

  Food manufacturers add this grape seed extract into fruit-flavored solid beverages, collagen meal replacement powder and antioxidant nutrition shakes. It brings natural reddish tone and mild fruit aroma without strange bitter taste, matching clean-label production demands. These antioxidant drinks are popular among office workers and fitness crowds in global supermarket health sections.

• Anti-Oxidation Skincare & Facial Care Raw Material

  Cosmetic brands incorporate the powder into anti-aging essences, brightening masks and sun-repair creams. OPC repairs oxidative damage caused by UV rays, fades dull complexion and strengthens skin barrier. It is a natural clean-label active ingredient widely used in organic skincare series for sensitive and aging skin groups.
