Products Description:
We supply high-purity Trans-Resveratrol (CAS 501-36-0) from two sustainable sources: traditional extraction from Polygonum cuspidatum root and modern fermentation technology. The fermentation-grade offers exceptional purity (>99.5%) and is free from botanical variances, while the plant-derived version provides a naturally sourced option. Both are ideal for capsules, tablets, and health supplements.
