Description

Natural Resveratrol (5–99%) is a premium botanical extract derived exclusively from Polygonum cuspidatum (Japanese Knotweed), one of the richest natural sources of trans-resveratrol. This highly valued active ingredient appears as a brown to white fine powder, depending on purity level. It carries the molecular formula C14H12O3, with a molecular weight of 228.25, and corresponds to CAS No. 501-36-0. With strong brand recognition as a natural antioxidant and anti-aging component, it is widely used across nutraceuticals, cosmetics, functional foods, and pharmaceutical R&D applications.
Produced in facilities certified under GMP, ISO22000, HACCP, HALAL, and KOSHER, our resveratrol undergoes rigorous quality controls, ensuring it meets strict EU standards for PAHs, pesticide residues, plasticizers, and ETO. Each batch is guaranteed 100% plant-derived with no excipients, such as dextrin or carriers. To verify its authenticity, we provide Carbon-14 reports (confirming natural botanical origin vs synthetic sources) and Carbon-13 reports (distinguishing it from fermentation-derived resveratrol). These certifications reinforce reliability for premium, clean-label, and regulatory-sensitive markets.
