Natural Japanese knotweed extract, 10% water-soluble resveratrol ingredient.
Water Soluble Resveratrol 10% from Polygonum Cuspidatum, No Additives, High Absorption
Natural itadori-derived, water-soluble high-function resveratrol. A next-generation antioxidant ingredient that enhances absorption and formulation flexibility.
This product is a functional ingredient made from the plant Polygonum cuspidatum, processed into a water-soluble type of naturally derived resveratrol using proprietary technology. Compared to conventional fat-soluble resveratrol, it excels in dispersion and solubility in water, making it suitable for a wide range of formulation designs such as beverages, granules, and powdered products. The main component, resveratrol, is a polyphenol with strong antioxidant properties that reduces oxidative stress by eliminating free radicals in the body, supporting anti-aging care. It has also been reported to have various physiological activities, including regulating blood cholesterol balance, reducing cardiovascular risks through platelet aggregation inhibition, anti-inflammatory effects, immune modulation, and antibacterial and antiviral activities. This product is standardized to a content of 10%, allowing for functional labeling design and stable quality control. The raw material is 100% derived from natural Polygonum cuspidatum, and no excipients such as dextrin are used. It also complies with EU standards for polycyclic aromatic hydrocarbons (PAHs), plasticizers, pesticide residues, and ethylene oxide (ETO). This is a high-value-added ingredient suitable for the international market for health foods and dietary supplements.
