Time：2026-10-22Lixing is a phosphatidylserine (PS) manufacturer that sells bulk powder at factory-direct wholesale prices to dietary supplement producers and private-label brands, addressing the need for certified, allergen-free material with stable batch-to-batch consistency.
Core Selling Points
50% concentration measured by HPLC – Each lot contains at least 50% phosphatidylserine, so you can calculate dosages and label claims without compensating for assay variation.Non-GMO sunflower lecithin base – The PS is derived from sunflower rather than soy, eliminating common allergen concerns and enabling a clean source statement.
Factory-direct wholesale pricing – Lixing sells from its own manufacturing site with a 25 kg minimum order, reducing material costs compared to trading-company markup.
Third-party tested COA – Every batch carries heavy metal, microbial, and purity data from ISO 9001-certified production, verified by an independent lab.
Regulatory paperwork support – You receive phytosanitary certificates, MSDS, and analysis certificate templates to support import filing into the US, EU, and APAC markets.

Use Scenarios
A supplement brand developing a memory support formula uses this 50% PS powder because the quantified HPLC assay helps hit a 100 mg per two-capsule dose without excess raw material.A contract manufacturer filling private-label orders for brain health products relies on the sunflower-derived isomer to print "soy-free" on packaging and pass retailer allergen audits.
A procurement team preparing a quarterly production run orders 25 kg to 100 kg lots directly to keep per-unit ingredient cost predictable against formula cost spreadsheets.
A clinical trial sponsor studying cognitive benefits in adults purchases PS with a full COA and high-purity documentation to maintain GMP compliance during study formulation.
A distributor targeting the European dietary supplement channel chooses this PS because the supplied MSDS and allergen statement align with EU food additive registration needs.
Frequently Asked Questions
What is the minimum order quantity for phosphatidylserine bulk powder?
The minimum order quantity is 25 kilograms for standard 50% phosphatidylserine powder. Trial orders of 5 kilograms are available at a higher unit price so your quality team can test the material before committing to production volumes. For continuous supply, we offer scheduled delivery contracts of 500 kilograms and above.
Can I get a free sample before placing a bulk order?
Yes, we provide a free 100 gram sample for evaluation. The sample ships with a copy of the last batch COA and a short specification sheet, but freight charges for express courier delivery are collected up front. If you place a confirmed bulk order later, the sample freight cost is deducted from the invoice.
How do you guarantee quality consistency between batches?
Our production is ISO 9001 certified and every batch is tested in-house along with independent lab verification. The assay, heavy metals, microbiology, and moisture results are recorded on a lot number basis. You receive a complete COA with each shipment, and we also store retained samples for 24 months after delivery to support discrepancy investigations.
Is your phosphatidylserine derived from soy or sunflower?
Sunflower. The lecithin source is non-GMO sunflower, which means the phosphatidylserine does not contain soy protein residues. We use enzymatic conversion from sunflower phospholipids, so no soybean-derived raw materials enter the production line. This is particularly important for customers who need to label products as soy-free or avoid potential soy allergens in their formulations.
What purity concentrations are available for phosphatidylserine powder?
Standard purity is 50% measured by HPLC. We also offer a 20% concentration for customers using liquid or soft gel formats where higher polysaccharide content helps emulsification. Custom assay below 20% is possible if you have a non-standard formulation requirement and meet the minimum volume.
Does the manufacturer support regulatory filings for import into the US or EU?
Yes. Each shipment includes a certificate of analysis, non-GMO statement, allergen declaration, MSDS, and phytosanitary certificate for courier or sea freight. We also structure documents to match FDA CDER and EU Novel Food dossiers when your customer requests specific paperwork. We have experience working with freight forwarders and customs brokers in both regions.
What is the typical lead time for a 25 kg order?
Lead time for a standard 25 kg order is 7 business days after payment if the material is in stock. For custom purity or 500 kg sea freight orders, allow 15 to 20 business days because production and QA testing take additional time. Shipping duration depends on destination.
Differentiation Summary
Compared to trading companies that resell phosphatidylserine from multiple sources, Lixing controls production from raw lecithin to final powder. That tightens purity tolerance, keeps the allergen-free supply chain documented, and removes intermediary markup. This 50% sunflower-derived PS fits brands that require soy-free cognitive ingredients with dependable certificates for international markets.
