Product Description
resveratrol Extract is a naturally occurring polyphenol primarily derived from Polygonum cuspidatum (Japanese knotweed) and grape skins. As one of the most recognized Plant Extracts in the global nutraceutical market, resveratrol is widely used in Nutritional Ingredients, Anti-aging Ingredients, and Cosmetic Ingredients due to its strong antioxidant and longevity-associated properties.
In B2B markets across the US, EU, and AU, resveratrol is a key component in Herbal Extracts , Sports Nutrition Ingredients, and premium supplement formulations. Buyers prioritize high-purity Standardized Extracts (typically 98% trans-resveratrol), consistent supply chains, and OEM-ready formats.
