Grape Seed Extract 95% Oligomeric Proanthocyanidins (OPC) is a high-purity natural polyphenolic compound extracted and isolated from the seeds of the grape species Vitis vinifera L. Precisely determined by High-Performance Liquid Chromatography (HPLC) or Ultraviolet Spectrophotometry (UV), this product ensures a stable proanthocyanidin content exceeding 95%. It appears as a reddish-brown fine powder with the characteristic aroma and taste of the product.
Grape Seed Extract is recognized as one of the most potent plant-derived antioxidants discovered to date. Its primary active component, Oligomeric Proanthocyanidins (OPC), possesses a free radical scavenging capacity 50 times greater than Vitamin E and 20 times greater than Vitamin C. Proanthocyanidins are widely present in nature and have been the subject of research for over 30 years. Due to their excellent solubility in water and alcohol, combined with their vibrant color and significant efficacy, high-quality OPC is extensively incorporated into health supplements, foods, and cosmetics.
This product is manufactured using advanced extraction techniques to ensure the stability and high bioavailability of its active components. Proanthocyanidins represent a large class of polyphenolic compounds, primarily composed of catechins, epicatechins, gallic acid, and epicatechin gallate. The 95% specification is the industry-standard concentration in the market, ensuring reliable efficacy while offering excellent cost-effectiveness.
