This ingredient is distinct from the typical grapeseed powders sold with the 95% OPC spec. Oligomeric Proanthocyanidins are a family of polyphenolic chemicals that have been shown to be very powerful scavengers of free radicals, far more powerful on a weight for weight basis than Vitamin C or Vitamin E.
A high-purity extract means that you can deliver effective dosage in a compact capsule or tablet size, which is a big plus for supplement formulators. This directly minimises excipient load and preserves your finished product clean label.
In cosmetic applications, OPC-rich extracts are recognised for their ability to maintain collagen stability and protect skin cells from oxidative stress, making this ingredient particularly relevant for anti-aging serums, facial creams and functional skincare lines.

Each batch of organic grapeseed extract powder is analysed by HPLC (High-Performance Liquid Chromatography) and UV Spectrophotometry. HPLC allows for accurate identification and quantification of compounds and UV testing validates the total polyphenol concentration. Using both procedures assures accurate and dependable findings – not overestimated by non-active chemicals.
Production is under quality management system ISO 9001 and GMP-based manufacturing system. The quality control process consists of raw material inspection, in-process monitoring and end product release testing.
Prior to the release of any batch, all microbial limits, heavy metal concentration and possible pollutants are assessed. HALAL and KOSHER certifications provide guaranty that the ingredient is manufactured and handled according to internationally recognised standards, eliminating regulatory hurdles for your market.


Product Applications
Dietary Supplements: The main active ingredient of antioxidant capsules, immune support softgels and cardiovascular health tablets is OPC at 95% concentration. The fine powder form flows readily and encapsulates efficiently without overusing binders.
Functional Foods and Beverages The extract is included in super food blends, antioxidant drink mixes and fortified nutrition bars. Its brownish red colour also provides visual clues of natural origin – useful for clean-label product positioning.
High-End Cosmetics & Skin Care: High-OPC grapeseed extract helps protect collagen and diminish the visible signs of oxidative skin ageing in topical applications. It is utilised in serums, creams and face masks for premium customer sectors.
Sports Nutrition: The ability of OPC to neutralise free radicals also makes it a perfect ingredient in antioxidant recovery mixes, especially in post-workout formulae that help reduce oxidative stress on muscles.

OPC is quite stable and will not deteriorate if stored properly. Storage criteria are as follows:
The powder is quite hygroscopic , therefore it easily collects moisture from the air . It is highly suggested to store in original vacuum or nitrogen filled aluminium foil pack until the time of use in production.
Standard packing is 25kg per drum. Kraft drums contain vacuum composite film inner bags to protect the powder from moisture and oxidation during transit.
Customisable package options:
Depending on your order amount and timing you will have the option of Courier, Air Freight or Ocean Freight for shipping. In-stock items will ship within 2–3 working days of order confirmation. Support for small trial batches and big commercial volumes.

Shaanxi New Things Biotech has a contemporary production facility in Xi’an, China, equipped with supercritical fluid extraction technologies, molecular distillation equipment and fully automated production lines.
The plant operates with a digital manufacturing management system, providing full traceability from raw material receipt, through production, quality inspection and to final product delivery. That means you always know precisely where your component came from and how it was processed.
