Product Overview

Resveratrol is a naturally occurring polyphenol (stilbenoid) found in Polygonum cuspidatum (Japanese knotweed) root, grape skin, and red wine. Our bulk Resveratrol is standardized to ≥98% trans-Resveratrol by HPLC, the biologically active isomer most studied in published research. The CAS number 501-36-0 corresponds to the trans configuration, which is the form most formulators specify.

Sourced from Polygonum cuspidatum root extract, our Resveratrol is suitable for nutraceutical, cosmetic, and functional food applications. Literature suggests Resveratrol may support cellular health, healthy aging markers, and cardiovascular wellness when included in a balanced formula.
