Benefits & Application
- Resveratrol and resveratrol glycoside can significantly reduce serum cholesterol and triglyceride.
- Resveratrol glycoside has a strong inhibitory effect on lipid peroxidation, thus reducing the accumulation of lipid peroxides in the liver and reducing liver injury.
- Resveratrol glycoside can dilate blood vessels, inhibit platelet aggregation, improve microcirculation, protect vascular endothelium, and decrease blood pressure.
- Anti-tumor effect of Polygonum cuspidatum extract on tumor.
- Resveratrol and Polygonum cuspidatum extract have strong inhibitory effect on staphylococci, streptococci and some viruses.
- Polygonum cuspidatum extract can inhibit the contraction of tracheal smooth muscle induced by histamine.
- Polygonum cuspidatum extract also has antipyretic and analgesic effects, and has the effects of convergence, prevention of infection and anti-inflammation on scalded wounds. Oral administration also has hemostatic effect on upper gastrointestinal bleeding.
Applications
Resveratrol is a versatile high-purity ingredient with applications across three primary sectors: dietary supplements, cosmetics and skincare, and functional foods and beverages. Its high purity (≥98%) and natural origin make it suitable for formulations targeting health-conscious consumers.
- Dietary Supplements
In the dietary supplement industry, resveratrol is widely used in formulations for antioxidant support and cardiovascular wellness. It is commonly available in capsules, tablets, and powder sachets, with a typical dosage range of 50 to 500 milligrams per serving. Resveratrol is often combined with other complementary ingredients such as grape seed extract, vitamin C, or coenzyme Q10 to create synergistic formulations. Its fine crystalline powder form allows for easy blending with other supplement ingredients and is compatible with standard tableting and encapsulation processes.
- Cosmetics & Skincare
In the cosmetics and personal care industry, resveratrol is used in anti-aging and skin protection products. It is incorporated into serums, creams, and lotions at levels ranging from 0.5% to 2.0% of the total formulation. Resveratrol is valued for its compatibility with a wide range of cosmetic ingredients, including moisturizers, emulsifiers, and botanical extracts. In formulation, it is typically dissolved in the oil phase or in a suitable solvent such as ethanol or glycols before incorporation, and its stability is maintained across a pH range of 4.0 to 6.0. It is often combined with other antioxidants such as vitamin E, ferulic acid, or niacinamide to enhance formulation efficacy.
- Functional Foods & Beverages
In the functional foods and beverages sector, resveratrol is added to products such as health drinks, protein bars, and fortified snacks. Typical usage levels range from 10 to 50 milligrams per serving. For beverage applications, we recommend pre-dissolving resveratrol in a small amount of ethanol or suitable solvent before adding to the aqueous phase to ensure even dispersion and avoid precipitation. Its neutral taste profile ensures it does not affect the flavor of the final product. It is stable under standard pasteurization conditions and is compatible with most food matrices.

Packaging & Storage
Proper packaging and storage are essential to maintain the quality, purity, and stability of Resveratrol throughout its shelf life.
- Packaging
Our Resveratrol is available in multiple packaging options to accommodate different production scales and requirements. For sample and research purposes, we offer 1 kilogram and 5 kilogram packaging, typically using double-layer food-grade PE bags inside sealed, moisture-resistant drums. For commercial and bulk orders, we provide 25 kilogram packaging with the same high-quality inner lining and sealed drum construction. Custom packaging options are also available upon request, tailored to specific shipping and production needs. All packaging materials are food-grade, designed to protect the product from light, moisture, and physical damage during storage and transport, with heat-sealed inner bags ensuring an airtight seal.
- Storage Conditions
To preserve quality and extend shelf life, Resveratrol should be stored at room temperature, below 25 degrees Celsius, in a dry environment with relative humidity below 60 percent. The product must be protected from direct sunlight and strong artificial light, as exposure to light and heat can accelerate degradation. Containers should be kept tightly sealed when not in use to prevent moisture ingress. For long-term storage, we recommend storing the product away from strong-smelling or hazardous chemicals to avoid cross-contamination.
- Shelf Life
Under recommended storage conditions, Resveratrol has a shelf life of 24 months from the date of manufacture. After opening, we recommend using the product within 6 months to ensure optimal purity and performance. The product should be re-sealed immediately after each use to prevent moisture absorption and maintain product integrity.
- Handling Precautions
Resveratrol is sensitive to moisture and should be handled with care. We recommend re-sealing the inner bag immediately after each use to prevent caking or degradation. The product should be stored away from heat sources and direct sunlight. Clean, dry, and contaminant-free utensils should be used when handling the product. Implementing first-in-first-out inventory practices is advised to ensure product freshness. Before use, the product should be inspected for any visible changes in appearance, colour, or odour. If any deviation from the original specifications is observed, we recommend contacting our quality assurance team for guidance before proceeding with use. For specific storage requirements or custom packaging for long-term stability, please contact our technical support team. The recommended storage conditions are based on standard industry practice; for applications requiring extended shelf life or specific climate control, we recommend conducting stability studies under the intended storage conditions. Samples are available for stability testing upon request.
