Trans-Resveratrol Powder

Trans-Resveratrol Powder — High-Purity Natural Extract for Premium Supplement & Skincare Formulations

Trans-resveratrol powder is widely known as one of the most bioactive polyphenols found in nature, valued for its strong antioxidant, anti-inflammatory, and cellular-protective properties. At CHEN LANG BIO TECH, we produce high purity and quality trans-resveratrol extracted from Polygonum cuspidatum, following a controlled and carefully monitored process to preserve the integrity of the trans-isomer while delivering consistent quality from batch to batch.

For many of our customers—nutraceutical brands, contract manufacturers, formulators, and cosmetic developers—trans-resveratrol is a core ingredient in anti-aging, wellness, and beauty applications. Over the years, we’ve learned that what these customers need most is not only purity on paper but a material that performs reliably, looks clean, and is supported by a responsive supplier they can trust. This is exactly where we focus our efforts.

 

⭐ What Makes Our Trans-Resveratrol Stand Out

While resveratrol appears on many ingredient lists, the difference between a good-quality extract and an inconsistent one becomes clear the moment you begin scaling production. Color variations, isomer degradation, unexpected odors, or inconsistent assay values can create serious challenges.

● High Product Whiteness

Our product has excellent whiteness, with a value exceeding 90. Compared with traditional processes, it achieves a significant quality upgrade and better meets the high appearance-purity requirements of various application scenarios.

● Advantages in Bulk Density and Flowability

The product shows outstanding bulk density performance, with a loose bulk density ≥ 0.35 g/cm³ and a tapped bulk density ≥ 0.7 g/cm³. Its flowability supports smooth operations such as feeding and mixing, helping users reduce material residue and loss during use.

 

● Multiple Specifications Available

 

High-purity and various concentration grades:

Purity is controllable and content is accurate, enabling formulation for different concentration requirements.

Granular products: Good dispersibility, easy dosing, and simplified production mixing processes.

Water-soluble products: Strong hydrophilicity, easy to dissolve, suitable for water-based formulations.

Lipid-based products: High bioavailability and excellent stability, meeting the needs of high-end application scenarios.

Comprehensive customized solutions: Parameters can be adjusted as needed to match exclusive formulation requirements.

 

● High Product Safety

Produced using GRAS-certified safe microbial strains, with no endotoxin residues. Compared with traditional chemical or plant-extraction processes, the product contains minimal solvent residues and no pesticide or plasticizer residues.

CHEN LANG BIO TECH’s resveratrol shows an acute oral LD50 > 5000 mg/kg in ICR mice. According to acute toxicity classification standards, this product is considered practically non-toxic.

 

● Comprehensive Third-Party Testing

Testing reports from the authoritative organization SGS can be provided for heavy metals, pesticide residues, microbial residues, and other related indicators.

● Consistent and reliable batches

Our customers appreciate that every shipment meets the same specifications—an essential requirement for brands scaling global distribution.

⭐ How We Produce Consistently High-Quality Trans-Resveratrol

Producing a stable, high-purity trans-resveratrol involves far more than extraction alone. The active compound is delicate and requires careful handling to prevent conversion into less active forms.

Here’s what we do differently:

✔ Raw Material Expertise

We partner with long-term herb suppliers who understand the importance of polyphenol-rich plant material. Stable sourcing allows us to maintain consistent potency year-round.

✔ Precision-Controlled Extraction

Temperature, solvent ratio, and purification steps are closely monitored to protect the delicate trans-isomer from degradation.

✔ Multi-stage purification

Impurities are removed gradually to avoid damaging the active compound, resulting in a bright, clean powder.

✔ Full QC Testing on Every Batch

Each batch undergoes:

•HPLC assay

•Impurity profiling

•Microbial testing

•Heavy metal screening

Every customer receives a COA and chromatogram detailing the quality of the material they receive.

✔ GMP-aligned operation

We maintain strict batch traceability, documentation, and quality oversight to support long-term partnerships and regulatory compliance.
