Time：2026-10-13Product Definition
Lixing Phosphatidylserine Powder is a non-GMO sunflower-derived phospholipid ingredient for supplement manufacturers and formulators who need a consistent, price-stable source of cognition-supporting raw material.
Core Selling Points
20% minimum purity (HPLC) – Provides a standardized active ingredient dose, reducing formulation adjustments caused by raw material variability.Non-GMO sunflower lecithin base – Eliminates soy allergen exposure and supports clean-label claims for “soy-free” end products.
D50 particle size of 120 μm – Ensures uniform blending with excipients, preventing segregation in capsules or tablets.
Available in 20 kg, 25 kg, or 40 kg packaging – Allows lot-size alignment with production batches and lowers warehouse holding costs.
Annual price contract option – Fixes unit price for 12 months, protecting buyers from spot-market fluctuations in phospholipid raw materials.

Applicable Scenarios
A contract manufacturer producing memory-support capsules uses standard 20% PS powder to meet label claims without over-filling.A sports nutrition brand developing a focus drink powder benefits from mild-flavor, allergen-free sunflower-derived PS.
A raw material distributor signs a 12-month fixed-price contract for 25 kg drums, stabilizing resale prices for customers.
A cross-border e-commerce private label launching “study focus” gummies can custom-order 50% purity PS to reduce excipient load.
A research laboratory pilot-testing a new nootropic formula buys a 1 kg sample with a COA to prequalify the ingredient before scale-up.
FAQ
1. What is the minimum order quantity for Lixing Phosphatidylserine?
The MOQ for standard 20% purity is 20 kg. For 50% purity, the MOQ is 5 kg. Tiered pricing applies to orders above 100 kg. Contact our sales team for a current quotation. A 1 kg sample pack is available separately, and sample costs are deductible from the first bulk order.
2. How does the annual price contract protect against raw material price changes?
Under the contract, the unit price remains fixed for 12 months regardless of market shifts. This allows purchasing teams to budget accurately. The contract also reserves monthly production capacity, ensuring the agreed volume stays available even during phospholipid supply shortages.
3. Does this phosphatidylserine contain soy allergens?
No. The product uses non-GMO sunflower lecithin as the starting material and is processed on dedicated lines. Each batch is screened for soy residues, with results shown as “not detected” on the COA. The finished powder is suitable for soy-free product labels.
4. Can I request third-party testing for heavy metals and microbiological limits?
Yes. SGS or Eurofins testing can be added to your purchase order. Third-party reports are issued within 10 working days after sampling. Testing cost is included for orders above 100 kg; smaller orders share the cost 50/50.
5. What is the lead time for standard and custom-purity orders?
Stock items of 20% purity ship in 5 business days. Custom 50% purity orders require 15 business days after technical contract confirmation. All shipments include COA and MSDS. For urgent orders, an express lane is available at a 5% surcharge.
6. How should the powder be stored to maintain the 24-month shelf life?
Keep the original sealed container in a cool, dry place at 10–25 °C, away from direct sunlight and volatile organic compounds. After opening, reseal the inner bag immediately and use within 30 days. Storage below 25 °C and below 60% relative humidity prevents caking and oxidation.
7. What documentation is provided with each shipment?
Every shipment includes a Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and packing list. For contracted annual supply, a monthly inventory report is also provided. Documentation is issued in English and can be notarized for import customs declaration.
8. Can you supply 50% purity phosphatidylserine for gummy production?
Yes, 50% purity is available as a custom grade with a 5 kg MOQ. This grade has a smaller particle size, D50 90 μm, for better dispersion in low-moisture gummy slurries. Lead time is 15 business days after approval; a separate technical datasheet is included.
Differentiation Summary
Compared with soy-derived PS, Lixing’s sunflower-based version removes allergen risks and builds price stability via annual fixed-price contracts. It suits mid-size manufacturers that prioritize predictable costs and traceable documentation over spot-market flexibility. Standard 20% purity, size-specific packaging, and third-party tested documentation make it a practical supply option for cognitive health brands.
