product details

Description

Grape Seed Extract is derived from the seeds of Vitis vinifera, a fruit cultivated for thousands of years and traditionally valued not only for winemaking but also for its health benefits. In European folk medicine, grape seeds and skins were used for circulation, wound healing, and vitality support. Today, grape seed extract is one of the most widely recognized antioxidant supplements worldwide.

The extract is standardized to oligomeric proanthocyanidins (OPCs ≥95%), highly potent polyphenols known for their antioxidant and vascular-protective properties. OPCs help neutralize free radicals, promote collagen formation, and support circulatory function. Scientific studies indicate that grape seed extract may help maintain cardiovascular health, skin elasticity, cognitive performance, and overall cellular protection.

Commercial production involves cleaning and drying grape seeds, followed by aqueous–ethanolic extraction and purification to yield concentrated OPCs. The final product is a fine reddish-brown powder, stable under dry storage, soluble in ethanol, and partially soluble in water. Grape Seed Extract is widely applied in cardiovascular support formulas, skin and beauty supplements, and antioxidant nutraceuticals.

Product Processing

Standard and Certificates

All of our products are made in a GMP-compliant facility where every step of production is carefully managed. Over the years, our factory has passed several well-recognized audits, including HACCP, ISO22000 and ISO9001. The products also meet Kosher and Halal requirements, and we hold FDA registration as well. These certifications reflect the standards we follow rather than just labels we collect—they’re part of how we ensure consistency and safety in every batch.

Free Sample Available

If you’d like to get a feel for the product before placing an order, we can send you a free sample. In most cases, we provide around 10–20 grams so you can evaluate the quality yourself. For items with higher raw material costs, we will confirm the exact amount we can offer so everything is clear before shipping.

Standard Packaging and Private Label

For regular shipments, we usually pack goods in 1–5 kg aluminum foil bags, 10–20 kg cartons, or 10–30 kg fiber drums, depending on the item and order size.

If you’re planning to sell under your own brand, we also handle private labeling. We can help design and produce packaging with your logo or artwork so the products arrive ready for retail. Many customers find this saves them a lot of time compared with printing and repacking on their end.

Shipping Method

Orders under one metric ton are generally shipped through major express couriers such as DHL, FedEx, UPS or EMS. For larger quantities, we can arrange transport by sea or railway. The best method depends on your location and how quickly you need the goods, so we’ll help you choose the most practical option.

After Sale Services

Most of our products remain stable for up to two years, and we guarantee their quality within that period. If anything arrives below your expectations, our return process is straightforward. You can send back the portion in question, and we will refund the corresponding amount—no complicated procedures or hidden conditions.
