Inquire NowResveratrol (3,5,4'-trihydroxystilbene) is a naturally occurring stilbenoid polyphenolic compound produced by plants in response to environmental stress, injury, or pathogen attack. In industrial wholesale raw material sourcing, Trans-Resveratrol represents the biologically active isomer favored by pharmaceutical, nutraceutical, and cosmeceutical formulators across France and the wider European Union.
As a leading Chinese primary manufacturer, RAAG Biotech Co., Ltd. produces pure Trans-Resveratrol powder derived predominantly from the rhizome of Polygonum cuspidatum (Japanese Knotweed) as well as upcycled Vitis vinifera (Grape skin/vine) sources. The chemical conversion of cis-isomer to the biologically potent trans-isomer is strictly controlled during our ethanol-water extraction and fractional crystallization processes, yielding an assay range between 98.0% and 100.5% calculated on an anhydrous basis.

France occupies a unique position in the global longevity and botanical extract landscape. Driven by the scientific legacy of the "French Paradox" (the epidemiological observation of low coronary heart disease rates correlated with dietary polyphenols), French consumers and brand owners demand uncompromising analytical transparency and natural-origin claims.
French oral beauty brands incorporate micronized and liposomal Trans-Resveratrol to stimulate SIRT1 sirtuin pathways, combat oxidative dermal damage, and prevent collagen cross-linking. Ideal for anti-wrinkle beauty shots and nutricosmetic capsules.
Over 20,000 retail pharmacies in France stock cardiovascular and cellular health supplements. Formulating with RAAG's EP-compliant 98% Trans-Resveratrol guarantees batch consistency and meets strict ANSES nutrivigilance criteria.
Formulators in Grasse and Bordeaux leverage water-soluble Vitis vinifera grape extracts containing natural Resveratrol to create luxury topical creams, serums, and eco-certified organic skin protection formulations.
Navigating the regulatory landscape in France requires strict alignment with both European Union regulations and national French enforcement agencies such as DGCCRF (Direction générale de la concurrence, de la consommation et de la répression des fraudes) and ANSES.
Synthetic Resveratrol and high-purity Trans-Resveratrol derived from Polygonum cuspidatum are authorized under EU Novel Food Regulation (EU) 2016/1190. In food supplements intended for adults, the maximum authorized daily dose in France is established at 150 mg per day. RAAG Biotech provides standardized bulk batch density calculations to ensure tablet and capsule manufacturers achieve precise 150mg volumetric filling without weight variance.
Root extracts sourced from soil are inherently prone to PAH accumulation during industrial drying if unmonitored. Under EU Regulation 2023/915, Europe imposes the world's tightest limits on Benzo(a)pyrene and the sum of PAH4 (Benzo(a)pyrene, Benz(a)anthracene, Benzo(b)fluoranthene, and Chrysene). RAAG Biotech utilizes continuous indirect steam-jacketed drying instead of open coal/gas smoke drying, reducing total PAH4 to less than 5 ppb—well below the 50 ppb legal ceiling.
French consumers strongly prefer clean-label formulas without synthetic excipients. RAAG Biotech supplies 100% carrier-free Resveratrol powder as well as custom clean-label blends using organic rice starch or acacia fiber, eliminating silicon dioxide and magnesium stearate.
Founded in 2014 in the High-Tech Zone of Xi'an, China, RAAG Biotech Co., Ltd. operates a state-of-the-art GMP-audited botanical extraction plant. Unlike trading desks, we control the complete value chain from contracted planting bases to final purification.
We deploy dual extraction platforms: Supercritical CO2 fluid extraction for volatile oleoresins and multi-stage ethanol reflux combined with resin column chromatography for ultra-high monomer purification (98%+ purity).
Every batch of Resveratrol is analyzed prior to packing. Our lab is equipped with Agilent High-Performance Liquid Chromatographs (HPLC-DAD), Gas Chromatographs with Mass Spectrometry (GC-MS/MS), and ICP-MS for heavy metal quantification.
Our raw herbs originate from contracted GAP (Good Agricultural Practices) growing bases in Shaanxi and Henan provinces. Each drum carries a unique lot identifier linking the finished powder back to field harvest dates and drying logs.
We supply complete documentation packages for French regulatory submission: COA, MSDS, Process Flowchart, Allergen Statement, Non-GMO Certificate, ETO-Free Declaration, BSE/TSE-Free Statement, and PAH Risk Assessment.
