This product is derived from the rhizome of the plant Polygonum cuspidatum (Japanese knotweed) and is a naturally sourced resveratrol (trans-resveratrol) obtained through solvent extraction and purification processes. The content can be adjusted from 5% to 99% depending on the application, and only natural plant-derived materials are used. Resveratrol is a type of polyphenol with strong antioxidant properties, which is expected to reduce oxidative stress associated with aging by removing free radicals from the body. As a result, it has garnered attention in the fields of anti-aging care, lifestyle support, and health maintenance. Additionally, research has reported its functionality in various areas, including the regulation of blood lipid balance, maintenance of cardiovascular health through platelet aggregation inhibition, anti-inflammatory effects, immune modulation, and antibacterial and antiviral activities. In recent years, its adoption has expanded not only in beauty and anti-aging applications but also in the health food and dietary supplement sectors. It also complies with European standards regarding polycyclic aromatic hydrocarbons, plasticizers, pesticide residues, and ETO, ensuring high safety and reliability as a raw material for the international market.
