What Is Grape Seed Extract?
Grape Seed Extract is a plant-derived ingredient obtained from the seeds of Vitis vinifera L. and is widely recognized for its high concentration of proanthocyanidins, particularly OPC (oligomeric proanthocyanidin complexes). As a functional botanical raw material, it is commonly used in dietary supplements, nutraceutical formulations, food products, and cosmetic applications.
At Extracts China, grape seeds are sourced from dependable raw material channels, with harvesting typically occurring in autumn. The ingredient is produced through a controlled solvent extraction process designed to preserve the extract’s natural polyphenol profile while supporting batch-to-batch consistency and commercial scalability.
Grape Seed Extract has long attracted interest from formulators and buyers due to its antioxidant profile, technical versatility, and broad application value. In the European market, OPC-containing grape seed preparations have been used for decades in various product categories. For B2B customers, its appeal lies not only in functional positioning but also in its compatibility with a wide range of end-use formats.
