Grape Seed Extract

Grape Seed Extract is a natural active ingredient extracted from grape seeds, rich in antioxidants such as anthocyanins (OPC) and polyphenols. Its antioxidant capacity is 20-50 times that of vitamin C.

Our Grape Seed Extract (GSE) is derived from high-quality, non-fermented grape seeds (Vitis vinifera L.) sourced from premium vineyards in the Mediterranean and California-regions renowned for ideal grape growing conditions. Unlike ordinary extracts, we adopt an advanced cold-press extraction combined with eco-friendly 70% ethanol-water solvent technology, ensuring maximum retention of active nutrients without harmful residues. Actually, our extraction process is optimized to focus on low-molecular-weight oligomeric proanthocyanidins (OPCs), which boast higher bioavailability (over 90%) compared to high-polymer proanthocyanidins (PPCs) that cannot be absorbed through the intestinal tract.

We offer dual sourcing to match your brand's specific positioning and label requirements.

The core value of our Grape Seed Extract lies in its rich, naturally occurring active compounds, with a unique ratio of nutrients that sets it apart from generic extracts. Unlike most products that only highlight total polyphenols, we focus on bioavailable, functional components:

• Oligomeric Proanthocyanidins (OPCs): The primary active component (60%-95% concentration), consisting of dimers, trimers, and tetramers (polymerization degree 2-5). These small-molecule OPCs are easily absorbed by the human body, with a half-life of 7 hours, and are far more effective than high-polymer PPCs (polymerization degree >5) which cannot enter the bloodstream.
• Total Polyphenols: 30%-95% concentration, including catechins, epicatechins, and epicatechin-3-O-gallate-synergizing with OPCs to enhance antioxidant and anti-inflammatory effects.
• Flavonoids: Natural plant flavonoids (e.g., formononetin analogs) that support immune function and skin health, working in tandem with OPCs to amplify overall efficacy.
• Trace Nutrients: Small amounts of grape seed oil, amino acids, and minerals (e.g., choline, vitamin B2) that complement the main active ingredients, ensuring a holistic nutritional profile.

With an emphasis on a high OPC (Oligomeric Proanthocyanidins) concentration, we standardize our extract to include 95% proanthocyanidins. Unlike lower-grade polymeric extracts, these smaller molecules guarantee quick absorption and pass the blood-brain barrier.
