Product Specifications

​​​​​​​​​​​​​​Why Trans-Resveratrol Purity Matters?

All resveratrol extracts are not created equal. The bioactive form is Trans-resveratrol, not the Cis isomer. Most low quality extracts include residual Emodin (anthraquinones) which can upset the stomach of the final user.

Our bulk powder is then chromatographically purified to target Emodin levels below 1ppm, confirmed by HPLC. You receive a clean, powerful substance - not a crude botanical extract with undesirable chemicals carried over.

Concentration options range from 30% to 98% providing you the flexibility to choose the right purity level for your formulation and cost requirements.

Key Product Advantages

High Purity Active Formulation

Trans-resveratrol is extracted from premium Polygonum cuspidatum root and strictly standardised at each specification level. Every batch is tested by HPLC for active ingredient concentration, isomeric purity and contaminant levels.

Trusted Supply Chain

We address the acknowledged difficulty of seasonal crop variability with grape-skin-derived resveratrol with a controlled extraction procedure from farmed Polygonum cuspidatum. No matter what time of year you harvest, the quality is consistent, batch after batch.

Wide Formulation Compatibility

The white powder form is appropriate for encapsulation in capsules (recommend 80-mesh particle size for consistent dosing), compression into tablets, incorporation into cream and serum via liposomal carriers, and use in functional food applications. In liquid systems, formulators may use it in conjunction with cyclodextrin inclusion complexes or co-solvents to overcome its inherent hydrophobicity.

Application Scenarios 

Dietary Supplements

Trans-resveratrol is frequently utilised in capsule formulations for anti-aging and cardiovascular support. The 98% standardised grade provides the maximum potency per unit weight which allows for smaller capsule sizes without loss of efficacy.

Formulations for Cosmetics

Resveratrol’s antioxidant capabilities make premium anti-aging lotions and serums more effective. For topical usage it should be integrated in liposomal or nano-emulsion systems to ensure skin penetration and to avoid oxidative browning of the end product.

Functional Food & Beverages

The micronized or water dispersible grades can be added to energy bars, beverages and fortified foods. Adequate delivery systems meet the requirements of texture and thermal stability during pasteurisation and processing.

Quality Assurance and Safety

Every batch of our resveratrol bulk powder is manufactured in compliance with cGMP standards and is monitored by an ISO 9001-certified quality system. Tests include active ingredient concentration, moisture, ash, heavy metals, microbiological limits and Emodin levels – all recorded on a comprehensive Certificate of Analysis (COA) supplied every batch.

We employ advanced analytical tools like HPLC and GC-MS during the quality control procedure. HALAL & KOSHER certifications makes the goods appropriate for diverse worldwide market needs.

You can obtain a COA, specification sheet or sample before placing a bulk order. How we work is with transparency.

Storage and Handling Guidelines

Trans-resveratrol is sensitive to light. UV light immediately induces photo-isomerization from the active Trans-form to the inactive Cis-form, thus reducing product potency.

Use the following storage techniques to retain quality:

• Store in light resistant double sealed aluminium foil bags or opaque containers
• Store in a dry cool place away from heat & moisture
• Do not stay in the open air too long after unsealing.
• Storage Temperature: Under 25°C, Relative humidity under 60%
• Proper storage ensures purity and bioavailability across your production cycle.

Packing and Delivery

Standard packaging is 25kg/drum using vacuum composite film with aluminium foil nitrogen filled inner bags – optimised for moisture resistance, light protection and good shelf life during international transit.

We can custom package incorporating lower quantities, private-label drums and multi-lingual labelling. We have stock ready for immediate processing of your orders. Orders will be shipped within 2-3 working days following confirmation via courier, air freight or ocean freight depending on your destination and volume.

FAQ

Q1: What is the botanical source of your product?

A: It is extracted from the roots of Polygonum cuspidatum (Giant Knotweed), which provides a stable and scalable source of high-purity Trans-resveratrol year-round.

Q2: What is the difference between Trans-resveratrol and total resveratrol?

A: Trans-resveratrol is the bioactive isomer used in standardized supplements. Total resveratrol includes both Trans and Cis forms. When sourcing, always confirm the Trans-resveratrol percentage specifically.

Q3: Will you provide a COA for each batch?

A: Yes. A full Certificate of Analysis is issued for every lot, covering active content, appearance, moisture, ash, heavy metals, microbial limits, and Emodin levels.

Q4: Does your product contain Emodin?

A: Our purification process reduces Emodin to below 1ppm, verified by HPLC. This is important for supplement manufacturers targeting clean-label and digestive safety requirements.

Q5: Is resveratrol powder water-soluble?

A: No, it is hydrophobic. For liquid applications, use cyclodextrin complexes, ethanol/PEG co-solvents, or lipid carrier systems to achieve proper dispersion.

Q6: What specifications are available?

A: We offer 30% to 98% Trans-resveratrol purity. The right grade depends on your target dosage, product type, and cost structure — our team can help you select the best fit.
