Grape seed extract – Polyphenols
Grape seeds are the seeds of grapes, typically a byproduct of the wine industry. After being dried and separated, they contain compounds such as oligomeric proanthocyanidins (OPCs), linoleic acid, vitamins, and minerals. Among these, OPCs exhibit significantly higher antioxidant activity than vitamins C and E, enabling them to neutralize free radicals and slow down the aging process. They also provide protective effects on the cardiovascular system, skin, and nervous system, and are widely used in health supplements, skincare products, and edible oils.

II. Product Introduction
1. Source
Grape seed extract polyphenols at 80% are produced using high-quality grape seeds as raw material, processed through a series of steps including cleaning, drying, grinding, solvent extraction, ultrafiltration purification, vacuum concentration, and spray drying. The production process strictly adheres to industry standards for plant extracts, with rigorous quality control throughout the entire process—from raw materials to finished products—ensuring that the polyphenol content consistently meets or exceeds specified standards and preserving the natural active ingredients present in the raw materials.
2. Core Efficacy and Applications
(1) The field of health supplements and dietary supplements
This extract is rich in highly active polyphenols and proanthocyanidins, boasting strong antioxidant capacity and helping to neutralize free radicals in the body. It can be used as a key ingredient in dietary supplements such as capsules, tablets, and oral liquids, perfectly aligning with the modern population’s health needs for antioxidant support and enhanced immune protection, and complying with the production standards of the health supplement industry.
(2) The Cosmetics and Skincare Sector
Polyphenol ingredients can inhibit melanin production, alleviate oxidative damage to the skin, and also provide auxiliary moisturizing and soothing effects on the skin. They are widely used in skincare products such as toners, serums, creams, and face masks, and are suitable for various skin types—including sensitive skin—while meeting cosmetic raw material safety standards.
(3) Food and Beverage Sector
It can be added as a natural antioxidant to foods such as juices, tea beverages, baked goods, and edible oils, helping to slow down food oxidation and spoilage and extend shelf life. By replacing some synthetic antioxidants, it aligns with the food industry’s trend toward “natural and healthy” products. When using this ingredient, it is essential to comply with the relevant standards for permitted addition levels.III. Technical Specifications and Testing Standards
