Phosphatidylserine Supplier From China
Time：2026-09-11What Is This Product
Lixing supplies bulk phosphatidylserine (PS) powder — standardized at 50% or 70% assay purity, available from soy or sunflower sources — for dietary supplement manufacturers, functional beverage brands, and nutraceutical formulators who need a cognition-support ingredient with verified quality and export-ready documentation.
Core Selling Points
Purity 50% / 70% (HPLC) — Each batch delivers a verified assay value you can print on your finished supplement label without digestory guessing. Certificate of Analysis accompanies every shipment.Dual sourcing: soy and sunflower — The sunflower grade is 100% non-GMO and allergen-free, letting you position products as "soy-free" for allergic consumers in US and EU markets.
Water-dispersible powder, particle size 100% pass 80 mesh — Blends evenly in capsules, tablets, sachets, and functional beverages without clumping or requiring additional processing equipment.
Microbial safety: total plate count ≤1,000 CFU/g, E. coli negative, Salmonella negative — Meets international food-safety thresholds for dietary supplements, satisfying FDA and EFSA import expectations.
Heavy metal compliance: lead ≤2 ppm, arsenic ≤2 ppm, cadmium ≤1 ppm — Tested by atomic absorption spectroscopy, with results documented on the COA for regulatory filing.

Application Scenarios
Dietary supplement manufacturers — Formulate memory-support capsules or tablets using PS at 100–500 mg per serving, backed by assay values that match exact label claims.Functional beverage brands — Use the water-dispersible fine powder to develop cognitive drinks that stay stable in suspension without sedimentation during shelf life.
Nutraceutical contract manufacturers (CMOs) — Blend consistently across multi-ingredient stacks, reducing QA re-testing time and simplifying batch release for customer accounts.
Export trading companies — Ship with complete documentation — COA, health certificate, certificate of origin — that clears customs smoothly in the US, EU, Southeast Asia, and Japan.
Sports nutrition formulators — Incorporate PS into post-workout recovery formulas targeting cortisol response and mental focus, using the sunflower grade for allergen-free marketing claims.
Frequently Asked Questions
What purity levels of phosphatidylserine do you supply?We supply 50% and 70% assay grades verified by HPLC analysis, and can provide a certificate of analysis with the exact percentage for every batch. Custom purity grades are available for specific formulations, allowing you to match label claims precisely.
Is your phosphatidylserine derived from soy or sunflower?Both sources are available. Soy-derived PS uses non-GMO soy lecithin, while sunflower-derived PS is allergen-free and suitable for soy-free product claims. Specify the raw material source during order confirmation to ensure the COA reflects your requirement.
Can I get samples before placing a bulk order?Yes, we provide free samples of 50 g for quality evaluation, and you pay only for the express shipping cost. After testing in your lab, you may place a trial order of 25 kg to 100 kg depending on grade. Samples are dispatched within 3 working days.
What is your minimum order quantity for phosphatidylserine?Standard MOQ is 50 kg for both the 50% and 70% grades. For first-time clients, trial orders of 10 kg are accepted as a one-time arrangement, with pricing adjusted to standard contract rates once repeat orders begin.
Does your manufacturing facility hold recognized certifications?Our factory holds ISO 9001, ISO 22000, and HACCP certifications issued by third-party assessment bodies. The PS also carries Kosher and Halal certificates. Documentation is shared during supplier qualification, and audit reports are available for regulatory filings.
How do you guarantee batch-to-batch consistency?Every production batch undergoes full assay, heavy metals, and microbial testing in our in-house laboratory, and results are printed on the COA. Third-party verification via SGS or equivalent laboratories is arranged quarterly and on customer request.
What are the production and delivery lead times?Production takes 15–20 working days after order confirmation and deposit. Air freight to most destinations requires 5–7 days; sea freight requires approximately 25–35 days depending on the port. Custom packaging or private-label design adds 5 working days.
What export documents do you provide for regulatory filing?We provide a complete pack: COA, MSDS, product specification sheet, certificate of origin, phytosanitary certificate, and shipping declarations. Files are formatted to support FDA, EFSA, and JFSA registration procedures, issued in English with company seals where required.
Differentiation Summary
Lixing's phosphatidylserine stands apart from generic Chinese suppliers through three operational differences: dual raw-material sourcing (soy and sunflower) with matching label claims, third-party verification from SGS-class laboratories on each production run, and regulatory documentation prepared to meet FDA, EFSA, and JFSA filing specifications. Purity is guaranteed at 50% or 70% by HPLC, with heavy metal and microbial test results printed directly on the COA rather than summarized. The facility holds both ISO 22000 and HACCP certifications, and a consistent 15–20 day production cycle supports dependable restocking schedules. This supplier fits buyers who prioritize raw material reliability, allergen-controlled product positioning, and documentation support for international supplement market registration.
