Lixing Phosphatidylserine Manufacturer Price
Time：2026-10-16Phosphatidylserine (PS) from Lixing is a high-purity bulk ingredient manufactured for dietary supplement and functional food companies that require a reliable wholesale supply without costly broker markups or batch inconsistencies.
All specifications below are laboratory-verified and based on current production lots. The data applies to the standard soy-derived PS powder, which is the most common grade for nutraceutical applications.
Core Selling Points
Assay 50% by HPLC – Lets formulators dose precisely at 100–300 mg per serving while keeping raw material costs predictable. Lower assay options (20 %) are available for cost-sensitive premixes.Reduced phospholipid oxidation index ≤ 10 – Ensures the PS remains chemically stable during tableting and encapsulation, extending finished-product shelf life beyond the typical 24 months.
Water content ≤ 3 % – Reduces clumping in hoppers and ensures free-flowing behavior in high-speed tableting presses and filler machines.
Microbial limits within USP 41 – Total aerobic count ≤ 1000 CFU/g, yeast and mold ≤ 100 CFU/g, and negative for E. coli and Salmonella. This simplifies incoming inspection and reduces rejection risk at the customer’s receiving dock.
Batch to batch coefficient of variation ≤ 2 % for assay – Tight control over the active ingredient means finished-product label claim checks consistently pass, minimizing your quality-control budget.

Applicable Scenarios
Contract manufacturers producing memory-conditioning supplements can order 100–500 kg per quarter with consistent assay, avoiding mid-run adjustments to raw ingredient dosing.Private-label brands scaling from 10,000 to 50,000 bottles per month benefit from a manufacturer-based price structure that protects gross margin at retail price points of $19.90–$34.90.
Functional beverage developers use the egg-free, soy-derived PS to formulate powdered sticks and softgels with neutral taste, relying on the low microbial load for ambient-temperature processing.
Research institutes running animal trials purchase the 20 % assay grade in small batches, getting lot-certified material for consistent oral-gavage or meal-mix administration.
Export traders supplying EU or Southeast Asia receive full COA, MSDS, and phytosanitary documents with each shipment, reducing clearance time at destination ports.
Common Questions And Answers
What is the wholesale price per kilogram for phosphatidylserine 50%?
The price depends on order volume and assay grade. As a general reference, a 100 kg order of 50 % PS powder is quoted at $55–$75 per kilogram FOB from the factory, with lower unit costs for annual contract volumes. Wholesale prices have dropped by about 15 % in the past year due to increased soy lecithin availability.
Do I need to test each batch when buying from Lixing?
No. Lixing provides a certificate of analysis (COA) for every lot, with assay, heavy metal, and microbial results from an in-house quality lab. Larger orders do include a third-party retesting option at the buyer’s cost, but historical batch variation is below 2 %, so routine skip-lot testing is sufficient.
Can you provide a free sample before wholesale purchase?
Yes. Send a request on your company letterhead, and Lixing will supply a 100 g sample with the following batch's COA. Freight to your country is paid by the buyer (usually $20–$40 by DHL or FedEx), which is credited toward the first wholesale order.
What is the minimum order quantity for a first-time customer?
The first order has a minimum of 100 kg. Once a contract is signed, you can split this into 10 kg submissions over four weeks. Refresh orders can be as small as 25 kg if you commit to buying 500 kg within 12 months.
What is the difference between synthetic and plant-derived phosphatidylserine?
Synthetic PS is made from bovine cortex, which carries allergy and religious-conformity risks. Plant-derived PS, like Lixing's, is extracted from soy lecithin and is safe for vegetarian supplements, halal products, and kosher-certified goods. It also avoids the prion-related concerns associated with animal-source ingredients.
Does phosphatidylserine require a feed supplement registration in the EU?
It depends on the final form. In the EU, PS is considered a novel food ingredient and must be pre-approved for use in supplements under Regulation (EU) 2015/2283. Lixing provides a compliance dossier supporting your own application, including purity data and stability reports.
How long is the shelf life, and does it need cold-chain shipping?
The powder has a 36-month shelf life at 25 °C or below. Standard sea freight in sealed bags is fine. No cold chain is required during transit, but the warehouse should be dry and ventilated after arrival. If the powder is stored at 40 °C for more than three weeks, re-test the assay before use.
What documents are included with a wholesale shipment?
You receive a complete packing list, commercial invoice, certificate of analysis, Bill of Lading, phytosanitary certificate (if needed), and manufacturer’s ISO certificate copy. For shipments to specific customs regimes, Lixing also provides a non-GMO statement and a production-flow description.
Differentiation From Other Suppliers
Most traders resell the same imported PS from generic Chinese factories with no control over production. Lixing operates its own independent workshop with a dedicated solvent-free extraction line. This reduces incoming inspection for the buyer and allows direct technical support for formulation problems. The company’s 50 % assay grade is produced under the same ISO 22000 standard applied to infant formula ingredients, which is uncommon in the phospho-lipid market. Companies that need consistent pending-catalog status, traceable sourcing, and a partner for custom particle-size or assay modifications will find Lixing a better fit than trading houses that offer only fixed standard grades.
