Discover our comprehensive portfolio of high-purity vitamins, minerals, trace elements, and plant extracts engineered to meet critical global quality metrics.
Quercetin (3,3',4',5,7-pentahydroxyflavone), a primary bio-flavonoid sourced naturally from raw materials like Sophora japonica, has transitioned from a niche nutritional supplement into an essential structural molecule for modern clinical nutrition, functional foods, cosmetics, and advanced animal husbandry. As the global demand for plant-based antioxidants surges, B2B procurement professionals require more than just a typical supplier—they need a certified manufacturer that guarantees traceability, consistent batch-to-batch purity, and strict regulatory compliance.
For European and global buyers, the presence of CE Certification is a critical benchmark. It validates that the plant extract is produced in adherence to European health, safety, and environmental protection standards. At Akston Health, we blend state-of-the-art chemical engineering with raw agricultural integration to supply premium Quercetin that meets pharmacopoeia requirements (USP, EP) and passes all strict EU contaminant thresholds for heavy metals, pesticide residues, and PAHs (polycyclic aromatic hydrocarbons).
Qingdao Akston Health Co., Ltd. is a trusted manufacturer and global supplier dedicated to delivering innovative health and nutrition solutions for the animal feed industry. With a strong commitment to quality, sustainability, and continuous innovation, we provide high-performance feed additives and nutritional ingredients that support healthier livestock, improved productivity, and safer food production worldwide.
Our comprehensive product portfolio includes choline chloride, amino acids, vitamins, minerals, and other functional feed additives designed to meet the nutritional requirements of poultry, swine, ruminants, aquaculture, and companion animals.
Our science-based formulations help optimize animal growth, enhance immune function, improve feed efficiency, and contribute to reducing the reliance on antibiotics in modern livestock production. We apply these scientific principles directly to our plant extract division, ensuring that active compounds like Quercetin maintain maximum bio-efficacy.
We work closely with qualified manufacturing partners and implement strict quality control systems throughout sourcing, production, and logistics to ensure every product meets international standards. Our experienced technical team provides customized solutions to support sustainable business growth.
Driven by these core values, Qingdao Akston Health Co., Ltd. has established long-term partnerships with clients across Asia, Europe, the Middle East, Africa, and the Americas. As your trusted partner in animal nutrition and phytogenic plant extracts, Akston Health will continue to develop innovative solutions that promote animal health, improve farming efficiency, and contribute to a more sustainable global agriculture industry.
Our extraction facility uses a highly optimized chemical and physical path to extract Quercetin from the dried buds of Sophora japonica. The process is designed to maximize active compound yield while avoiding thermal degradation or solvent cross-contamination.
Selection of premium Sophora Japonica buds rich in Rutin. The moisture, impurity levels, and pesticide residues are tested prior to processing to establish base purity markers.
Rutin is converted into Quercetin through a highly controlled acidic hydrolysis process. Temperature, pH levels, and reaction times are monitored to limit oxidation and preserve the raw chemical backbone.
We employ multi-stage ethanol recrystallization. This method eliminates organic impurities, yielding highly pure, crystalline Quercetin dihydrate without using harmful chlorinated solvents.
| Analysis Item | Specification Range | Testing Method (HPLC / USP) |

| Appearance | Light yellow to greenish-yellow fine powder | Visual Inspection / Organoleptic |
| Mesh Size | 100% through 80 mesh / Micronized options (200-325 mesh) | Sieve Analysis |
| Heavy Metals (Pb, Cd, As, Hg) | Pb < 3.0 ppm, As < 1.0 ppm, Hg < 0.1 ppm | ICP-MS (Inductively Coupled Plasma Mass Spectrometry) |
| Loss on Drying | 8.0% – 12.0% (Dihydrate) | USP <731> Gravimetric Method |
| Residual Solvents | Ethanol < 5000 ppm (Well below ICH limits) | GC-FID (Gas Chromatography) |
Every stage of production—from the raw materials storage to the final automated packing and sterilization—is conducted within standardized cleanrooms. Explore our physical facilities that support our high-purity Quercetin and feed additives manufacturing operations.
Quercetin functions differently depending on the matrix it is integrated into. We provide custom solutions engineered to address specific sector needs, ensuring high bio-availability and synergy with other active ingredients.
Often combined with Zinc, Vitamin C, or Bromelain to enhance cellular uptake, Quercetin is a key component in immune support supplements, cardiovascular health formulas, and seasonal allergy relief products. We offer micronized Quercetin powder that improves dissolution rates in capsule and tablet formulations.
Aligning with Akston Health’s core operations, Quercetin acts as a natural antioxidant in feed formulations. It helps reduce oxidative stress in pigs and poultry, stabilizes gut health, and serves as an effective natural alternative to synthetic growth promoters and antibiotics.
Due to its anti-inflammatory and antioxidant properties, Quercetin is used in topical creams and serums to soothe skin, mitigate UV-induced erythema, and target cellular senescence. Our cosmetic-grade material undergoes strict heavy metal testing to ensure purity.
As global supply chains face challenges, our manufacturing facilities in Shandong and partner networks across China provide reliable stability, competitive pricing, and efficient distribution.
Our manufacturing partner model operates under strict quality standards. We combine local agricultural sourcing with advanced chemical purification to manage trace contaminant risks from raw material intake to final export delivery.
