Our cGMP-audited facility manufactures standardized Kavalactones, pure monomers, and liposomal botanical extracts with lot-by-lot HPLC verification and complete regulatory documentation packages.
As a leading China Best Kava Extract Factory & Supplier, RAAG Biotech Co., Ltd. applies rigorous botanical analytical chemistry to ensure our commercial bulk Piper methysticum extracts deliver consistent physiological efficacy without adulteration or chemical instability. The primary active moieties responsible for the anxiolytic, neuroprotective, and muscle-relaxing properties of Kava are the six main lipophilic lactones (collectively designated as Kavalactones): Kavain, Dihydrokavain, Methysticin, Dihydromethysticin, Yangonin, and Desmethoxyyangonin.
Every commercial batch is profiled via High-Performance Liquid Chromatography (HPLC) against USP/EP reference standards to confirm exact Kavalactone percentages and eliminate non-noble alkaloid contaminants (e.g., Pipermethystine).
We strictly source authentic 5-year-old Noble cultivar roots (Vanuatu/Fiji strains), avoiding wild Tudei cultivars which contain elevated levels of flavokavains A & B responsible for prolonged sedation and hepatic stress.
Our industrial SFE (Supercritical Fluid Extraction) lines operate at 25–35 MPa and 40°C–45°C using food-grade CO2, yielding pristine lipophilic oleoresins without thermal degradation or toxic organic solvent residues.
Information Gain Insight: Unlike standard trading entities that source unverified field-dried whole root powders, our facility enforces a strict zero-stem/leaf intake mandate. Pipermethystine—an alkaloid proven to induce cytotoxic responses in human hepatocytes—is exclusively located in the aerial stems and leaves of the Kava plant. By raw material sorting and HPLC assay gating, our extracts contain undetectable levels of Pipermethystine (<0.001%).
| Analytical Parameter | Food-Grade Ethanol Reflux Extraction | Supercritical CO2 Fluid Extraction (SFE) | Water-Soluble Liposomal Microencapsulation |

Operating as a premier B2B manufacturer in Xi'an's High-Tech Industrial Zone, RAAG Biotech Co., Ltd. bridges the gap between agricultural cultivation and rigorous pharmaceutical-grade botanical manufacturing. Our modern production complex houses four dedicated extract lines, a 100,000-class clean room drying facility, and an advanced central analytical laboratory.
Our plant operates under ISO 9001:2015, ISO 22000 (HACCP), HALAL, KOSHER, and USDA Organic audited systems. Every batch exported to North America, Europe, and the Asia-Pacific region is accompanied by full regulatory documentation, including MSDS, Technical Data Sheets (TDS), Flow Charts, Allergen Statements, and Non-GMO Declarations.
From the initial harvest logs at our contracted Pacific island planting bases to the final heat-sealed aluminum foil drums, each lot is assigned an immutable internal code. This allows global QA managers to trace finished extract powders directly back to soil moisture metrics, harvest dates, and in-process temperature logs.
To eliminate reliance on third-party delays and ensure zero batch-to-batch variation, our QA desk conducts comprehensive testing on every production run prior to release:
The global botanical stress-relief and sleep supplement sector is undergoing a profound structural shift. Consumer demand is transitioning away from synthetic mood regulators and habit-forming pharmaceutical agents toward natural, non-addictive botanical modulators. Kava extract stands at the forefront of this market expansion due to its distinct GABA-A receptor modulation mechanisms.
Formulators in North America and Western Europe are aggressively launching non-alcoholic social beverages. This creates massive commercial demand for water-dispersible, cold-soluble Kava powders with reduced bitterness profiles.
Due to the lipophilic nature of Kavalactones, standard raw extracts exhibit limited intestinal absorption rates. Advanced buyers are adopting liposomal encapsulated Kava powders to achieve 4x-5x plasma concentration spikes with lower active dosages.
Regulatory authorities (US FDA, EFSA, TGA) require proof of Noble root origin and absence of hepatotoxic alkaloids. Formulators require factory-backed audit packages and independent COAs to clear international customs smoothly.
Below are authoritative responses from our technical regulatory and manufacturing teams addressing critical purchasing, quality assurance, and logistics questions.
Every commercial lot shipped by RAAG Biotech includes a comprehensive document file: Batch-Specific Certificate of Analysis (COA covering HPLC assay, heavy metals, microbial limits, and pesticide screens), Material Safety Data Sheet (MSDS), Technical Data Sheet (TDS), Flow Chart, BSE/TSE-Free Statement, Non-GMO Certificate, and Organic/Halal/Kosher certificates where applicable. Third-party verification reports by SGS or Eurofins can be arranged prior to vessel dispatch.
Our standard Minimum Order Quantity (MOQ) for commercial bulk Kava Extract powder is 1 kg (packaged in vacuum-sealed aluminum bags). For R&D lab verification, formulation trials, and HPLC reference matching, we provide complimentary 20g–50g sample kits accompanied by a matching lot COA via express international air courier (DHL/FedEx).
Hepatotoxicity concerns historically stemmed from two factors: the use of non-noble 'Tudei' varieties (high in Flavokavain B) and the inclusion of stem/peel parts containing Pipermethystine. RAAG Biotech strictly contracts only 5-year-old Noble root peeled stock. Our raw material intake protocol uses thin-layer chromatography (TLC) and HPLC to screen out any Tudei adulteration, ensuring our finished extracts are 100% safe for long-term dietary supplement application.
Yes. We offer custom particle sizing from standard 80 mesh up to micro-milled 200 mesh powders. For capsule fill machines, we can adjust bulk density through dry granulation. For water-soluble RTD beverage applications, we utilize food-grade carriers such as maltodextrin, acacia gum, or sunflower lecithin to create instant water-dispersible Kava powders that stay suspended without settling.
In-stock standardized grades (e.g., Kava 30% HPLC Powder) ship within 3 to 5 business days post-payment. Custom extraction runs or bespoke mesh specifications require 10 to 15 working days. We support EXW, FOB, CIF, DDP, and DDU shipping terms via air freight, ocean freight, and express courier, providing full customs clearance HS Code classification support (HS Code: 1302199090).
