 Our mission is to develop more high-quality raw materials that meet market demands through continuous exploration and innovation, thereby helping customers enhance their product competitiveness. Adhering to the values of "Quality First, Customer Priority, Continuous Innovation," we are committed to creating value for customers with excellent raw material quality. 

 Our slogan is: "Nature's Choice, Source of Quality!"
As the cornerstone of Durlevel Group's raw material supply chain, Xi'an Super Supplement Factory specializes in delivering high-purity botanical extracts, vitamins, amino acids, and food additives for the global nutraceutical industry. Our facility operates in 100,000-class GMP cleanrooms, equipped with fully automated production lines and advanced analytical instruments to ensure full traceability from raw material sourcing to finished product delivery.
We employ Ultrasound-Assisted Extraction (UAE) and Supercritical CO₂ Extraction (SFE) technologies to maximize bioactive compound yields. For instance, our curcuminoids achieve ≥95% purity, Ginkgo flavones ≥24%, and silymarin ≥80% standardization. All ingredients undergo rigorous testing via HPLC, GC-MS, and ICP-MS to guarantee compliance with strict limits for pesticides (483-item scan), heavy metals (Pb≤0.5ppm, As≤1ppm), and microbial contamination (TAMC≤1000 CFU/g).
Our quality systems are certified under ISO 22000, FSSC 22000, USDA Organic, and EU Organic standards. We provide comprehensive Certificates of Analysis (COA) and Technical Data Sheets (TDS) to support FDA, EFSA, and China Health Food registrations.
Our dedicated R&D Center, staffed with 20+ PhD and MSc researchers, focuses on enhancing bioavailability and formulation optimization. Key patented technologies include:
  • Microencapsulation: Improves solubility of lipophilic compounds (e.g., silymarin, CoQ10) to ≥85% dissolution rate
  • Chelated Amino Acid Complexes: Boosts mineral (Ca/Mg/Zn) absorption by 50%+
  • Low-Temperature Spray Drying: Preserves heat-sensitive actives (probiotics, collagen peptides)
We offer customized ingredient solutions, such as:
  • Standardized extracts at varying ratios (5:1, 10:1, 20:1)
  • Premix blends (vitamins + minerals + botanicals)
  • Advanced delivery formats (powders, microbeads, nanoemulsions)
To ensure sustainability, we operate GACP-certified farms in Qinling Mountains and Xishuangbanna, practicing organic cultivation (no chemical pesticides/fertilizers). A blockchain traceability system enables real-time tracking of planting, harvesting, and testing data.
For global compliance, we supply:
  • Religious Certifications: Halal (IFANCA), Kosher (OU)
  • Organic Certifications: USDA, ECOCERT, JAS
  • Stability Studies: Accelerated testing (40°C/75% RH, 6 months) for shelf-life validation
