OEM ODM Calcium Magnesium Zinc Vitamin D3 Capsules Private Label
- Chelated mineral matrix for >90% bioavailability
- Synergistic Vitamin D3 cholecalciferol fortification
Leveraging high-yield chromatographic separation and botanical synergy, ESNO Biotech manufactures turnkey private label capsules, standardized extract complexes, and bioavailable formulas tested to USP/EP pharmacopeial specifications.
Headquartered in Xi'an, Shaanxi—the epicenter of China's Qinling herbal botanical belt—ESNO Biotech combines 19+ years of extraction mastery with NSF 455-2 GMP validated manufacturing lines.
Crude extraction methods often thermally degrade primary active markers. ESNO Biotech operates closed-loop molecular separation systems designed to maximize bio-potency while guaranteeing residual solvent levels far below USP <467> and EP 5.4 limits.
Operating at controlled pressures (7.38 to 35 MPa) and mild temperatures (31.1°C to 45°C), our scCO2 platforms yield lipophilic constituents—such as gingerols, shogaols, and steroidal saponins—without thermal isomer degradation or petrochemical hydrocarbons.
For polar target molecules including Rhodiola rosavins, salidrosides, and polyphenols, selective multi-stage macroporous adsorption columns fractionate specific molecular weight tiers, desorbing inert carbohydrates and heavy ions before crystallization.
Continuous cavitation pulses disrupt rigid botanical lignocellulosic cell walls in medicinal mushrooms (Lion's Mane Hericium erinaceus), solubilizing high-molecular (1→3),(1→6)-β-D-glucans without cleaving active immunogenic branches.
The global herbal extract market is undergoing structural shifts away from generic commodities toward authenticated, molecularly verifiable, and low-carbon botanicals. B2B supply chain directors must navigate four critical trends:
Adulteration detection has shifted past simple TLC/HPLC testing. Major American and European retailers require certified species confirmation (ITS2 and rbcL DNA barcoding) to prevent botanical substitution in species like Rhodiola rosea versus Rhodiola crenulata.
European Commission (EC) 2020/2040 and USP guidelines have imposed near-zero thresholds for Pyrrolizidine Alkaloids (PAs) and Ethylene Oxide (ETO) residues. Sourcing directly from verified Chinese processors with validated gamma or steam sterilization is now mandatory.
Brand owners are scrutinizing Scope 3 supply chain footprints. Processing facilities utilizing solar-assisted solvent evaporation, high-efficiency condensate reclamation, and circular biomass spent recycling provide documented ESG advantages for tenders.
Poor oral bioavailability represents the primary drawback of polyphenol powders. Buyers increasingly specify pre-granulated, liposomalized, or microencapsulated powders capable of instant cold-water dispersion without phase separation.
Every bulk drum and finished batch shipped from our Xi'an export hub is accompanied by an authenticated Certificate of Analysis (COA) confirming adherence to the most rigid international compendia.

Headquartered in the Tangxing Digital Building in Xi'an High-Tech Zone, our manufacturing ecosystem bridges agricultural origin traceability with modern high-throughput pharmaceutical encapsulation.
Our facility operations conform fully to NSF 455-2 GMP, ISO 22000, HACCP, and EU/USDA Organic standards. Furthermore, our production capacity and trade history have been audited on-site by TÜV Rheinland, giving risk managers complete procurement confidence.
From stabilizing reactive antioxidants like Alpha Lipoic Acid to designing multi-ingredient longevity formulas (Urolithin A + PQQ), our senior formulation engineers optimize excipient compatibility, powder flow index, and dissolution disintegration times within our pilot R&D lab.
We break common factory barriers by providing stock private label formulas starting as low as 100 to 500 units for emerging brands, alongside mass-scale container shipments (2,000+ pcs for softgels and multi-ton raw botanical powder exports) to over 100 countries.
Everything technical compliance directors and supply chain managers need to know before initiating a formal sample request or production run.
Whether formulating next-generation nootropics, bioavailable bone matrices, or sourcing bulk standardized extracts, ESNO Biotech delivers uncompromising purity, rigorous testing, and factory-direct pricing.
