■ Product Description
Grape seeds are the small, hard seeds found inside grapes (Vitis vinifera). They are a rich source of polyphenolic compounds, particularly oligomeric proanthocyanidins (OPCs), which are widely recognized as some of the most potent natural antioxidants. Our premium Grape Seed Extract Powder is produced from carefully selected grape seeds sourced as a byproduct of wine and juice production, ensuring sustainable and efficient utilization of resources. Using advanced water or ethanol extraction followed by low temperature concentration and spray drying technologies, the powder preserves the full spectrum of bioactive compounds including proanthocyanidins (B1, B2, B3, C1), catechins, epicatechin, epicatechin gallate, and gallic acid.
Raw grape seeds have limited bioactivity due to their fibrous, lignified structure and low concentration of active compounds. Our grape seed extract powder solves these challenges by providing standardized proanthocyanidin content (up to 95% OPCs), excellent water solubility (for most grades), consistent batch to batch quality, enhanced bioavailability, extended shelf life, and year round availability. The powder is additive free, non GMO, and suitable for a wide range of industrial applications from dietary supplements and functional foods to beverages, cosmetics, and personal care products.
