High Quality Grape Seed Extract 95% Proanthocyanidins
Product Description
Grape Seed Extract is a premium, plant-derived active ingredient sourced from the seeds of Vitis vinifera (common wine grapes) or Vitis labrusca—grape varieties cultivated globally for winemaking, juice production, and table consumption. Once considered a waste byproduct of the wine and juice industries, grape seeds are now recognized as a rich reservoir of bioactive compounds, making their extract one of the most popular antioxidant supplements worldwide. With a history of traditional use in Mediterranean and European folk medicine for supporting vascular health, it has evolved into a versatile ingredient across wellness and beauty sectors.
The extract’s efficacy is defined by its proanthocyanidins (PAs)—a class of flavonoid polymers also known as oligomeric proanthocyanidins (OPCs). These compounds are 20–50 times more potent than vitamins C and E in neutralizing free radicals, making them the extract’s primary functional component. Reputable Grape Seed Extract is standardized to contain 80–95% total proanthocyanidins (with OPCs accounting for the majority), and undergoes rigorous testing for heavy metals, pesticides, and microbial contaminants to meet global quality standards (FDA, EU Regulation (EC) No. 1881/2006, GMP). It is non-GMO, vegan-friendly, gluten-free, and free from artificial additives, making it a safe and sustainable choice for various applications.
