Phosphatidylserine 51446-62-9 Supplier From China
Time：2026-11-09Product Definition
Lixing is a direct supplier of phosphatidylserine (PS) from China, providing bulk soy-derived phosphatidylserine powder (≥50% assay by HPLC) to nutrition and pharmaceutical formulators, solving the core pain point of batch-to-batch inconsistency and unreliable supply chains in cognitive health manufacturing.
Core Selling Points
Standardized Assay (≥50% by HPLC) : Enables formulators to achieve precise dosage with reduced excipient load, directly lowering per-unit manufacturing costs.Strict Heavy Metal Limits (Lead & Arsenic ≤1.0 mg/kg; Mercury ≤0.1 mg/kg) : Meets strict international food supplement standards, making the ingredient safe for products targeting children, adults, and the elderly.
Complete Batch CoA and Full Traceability Records : Simplifies FDA or NMPA regulatory submission processes and provides anti-counterfeiting assurance, ensuring smooth supplier audits.
GMP-Certified and HACCP-Controlled Production Environment : Maintains consistent quality control across standard production lines, significantly reducing the risk of production halts due to quality deviations.

Common Questions (FAQ)
1. Can your standard inventory hold a large commercial batch size?Our standard 50% purity stock is approximately 2 tons at all times. This inventory level supports orders ranging from small 1 kg trials to large 500 kg commercial shipments. With raw stock on hand, we maintain a lead time of up to 10 days shorter than the average trading intermediary, while strictly ensuring full batch documentation.
2. Will you provide documents that meet FDA or EU regulatory filing requirements?We supply full batch CoA created within our ISO 9001 and HACCP-certified facilities. The documentation clearly states compliance limits for lead (≤1.0 mg/kg) and mercury (≤0.1 mg/kg) as required by USP and EU monographs. For specialized filings, we can support the preparation of inspection certificates and raw material source declarations.
3. What is the typical bulk shipping time from China to the US?Ocean freight from major Chinese ports to the US West Coast generally takes 25 to 35 days depending on the shipping line schedule. This standard transit period is predictable and allows manufacturers to maintain a stable inventory flow. For time-sensitive restocking, expedited airfreight options are also available within 5 to 7 days.
4. Is this Phosphatidylserine powder suitable for children's gummy or chewable tablet formulations?Yes, it is suitable for formulas targeting pediatric nutrition. It meets strict safety limits for heavy metals, specifically keeping lead under 1.0 mg/kg and arsenic under 1.0 mg/kg. The powder's 80-mesh size allows for homogeneous blending and smooth incorporation into gum bases and tableting excipients.
5. Are your operations vertically integrated to prevent adulteration?Yes, Lixing extracts and standardizes this source in its own certified facilities in China. This vertical integration controls every step from crude soy oil fractionation to finished powder, minimizing third-party contamination risks and providing clear audit trails for consistent commercial manufacturing.
6. Do you provide small batch samples for new product development?We do offer 1 kg representative samples that come with complete analytical reports. This allows formulators to conduct necessary pilot testing and verify assay values independently. Sample pricing follows standard industry premiums and is fully rebated upon confirmation of a commercial order.
Differentiation Summary
Unlike typical trading houses or repackagers, Lixing operates its own standardized phosphatidylserine extraction line, controlling the process from degummed soy lecithin to the final standardized powder with in-house HPLC equipment. This vertical integration effectively eliminates third-party adulteration risks and provides authentic, verifiable documentation for procurement audits. For US and EU formulators who require rigid heavy metal specifications and consistent crystalline solubility, this Chinese supplier offers a unique hedging option against volatile raw material sourcing disruptions.
