Grape Seed Extract is a natural functional raw material refined from high-quality seeds of wine grapes or special edible grape varieties. Through modern processes—including cleaning, drying, crushing, solvent extraction, purification, and spray drying—it achieves high purity and stable effective substance content. Recognized as a potent antioxidant source, it is rich in flavonoids, linoleic acid, phenolic compounds, and its core active component, proanthocyanidins (OPC)—a natural substance with antioxidant capacity far exceeding vitamin C and vitamin E. It also contains resveratrol, catechins, and other nutritional ingredients, whose synergistic effects make it highly favored in the health field.
