Product Description

Resveratrol 50% is standardized extract derived from the root of Polygonum cuspidatum (Giant Knotweed). We supply two versions produced by fermentation or botanical extraction, standardized to 50% trans-resveratrol determined via HPLC, alongside naturally occurring polydatin and other polyphenols. The light brown fine powder serves as an economical antioxidant raw material. It is widely adopted in dietary supplements targeting cardiovascular care and anti-aging, also applicable for cosmetic formulations. Unlike high-purity 98% resveratrol, this 50% version preserves the natural spectrum of plant polyphenols and offers cost advantages for compound blending.
