resveratrol Extract is a naturally occurring polyphenol primarily derived from Polygonum cuspidatum (Japanese knotweed) and grape skins.

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.
