Most conventional resveratrol powders on the market contain mixed isomers or incomplete purification, leading to unstable component activity and poor batch consistency. Our product focuses on trans-isomer refinement, effectively reducing cis-resveratrol and impurity residues. The finished powder presents uniform off-white to fine white color, loose and free-flowing texture with slight natural plant odor. No artificial pigments, synthetic flavors or preservatives are added. With stable chemical properties and high component purity, it serves as a standard raw material for clean-label nutraceutical formulas, cosmetic ingredient compounding and large-scale bulk export trade.

Our Supplier Advantages

We adopt standardized plant extraction and low-temperature purification production lines for Trans-Resveratrol. Strict isomer screening and batch testing procedures ensure high trans-isomer ratio, low impurities and consistent quality for bulk export orders.

• Premium Plant Source Control: Select high-quality Polygonum Cuspidatum root raw materials, strictly screen and remove deteriorated raw materials and impurities, ensuring stable raw material foundation.

• Precision Isomer Purification: Adopt multi-stage crystallization and isomer separation technology to maximize trans-isomer retention and reduce invalid cis-isomer content, optimizing ingredient purity and stability.

• Low-Temperature Protection Process: The whole low-temperature processing avoids active ingredient loss caused by high-temperature treatment, retaining natural polyphenol activity.

• Full Batch Quality Inspection: Each batch undergoes HPLC purity detection, impurity analysis, heavy metal and microbial testing before shipment, with complete test reports provided.

• Flexible Custom & Service Support: Support purity and particle size customization, private label packaging, and provide complete export documents such as COA and MSDS.

Packaging & Storage Guidelines

• Standard Export Packaging: 1kg aluminum foil vacuum bag; 25kg food-grade fiber drum with inner plastic lining bag

• Storage Conditions: Store in cool, dry, dark and ventilated warehouse, avoid high temperature, humid environment and long-term strong light exposure.

• Storage Reminder: Trans-resveratrol powder is sensitive to light and moisture. Please keep tightly sealed after opening to prevent ingredient oxidation, moisture caking and activity attenuation.

FAQ

Q1: What is the difference between trans-resveratrol and ordinary resveratrol?

A1: Trans-resveratrol is the stable and mainstream active isomer in natural resveratrol. Ordinary resveratrol usually contains mixed cis and trans isomers with unstable component ratios. Trans-resveratrol powder features higher purity, better stability and more reliable formula adaptability.

Q2: Is your trans-resveratrol powder added with any fillers?

A2: Our bulk trans-resveratrol raw material is pure plant extract powder, without extra fillers, pigments or flavorings, maintaining clean and pure ingredient properties for independent formula compounding.

Q3: What are MOQ and delivery time?

A3: Small sample orders are supported for quality testing and formula trial. Conventional 98% and 99% specifications are in stock for fast delivery. Customized technical indicators require separate production cycle confirmation.
