Phosphatidylserine Powder Supplier From China
Time：2026-09-171. Product Definition
Phosphatidylserine powder from Lixing, a China-based supplier, provides a high-purity (≥98% via HPLC) sunflower-derived ingredient for nutraceutical manufacturers seeking a clinically documented cognitive support compound.
2. Core Selling Points
≥98% purity (HPLC) – Enables precise dosing and accurate label claims; every batch is documented with a Certificate of Analysis (COA) showing individual impurity profiles.Sunflower lecithin source – Free from soy allergens and non-GMO certified, lowering the risk of product recalls for allergy-sensitive brands and supporting clean-label positioning.
Heavy metal content under regulatory limits – Lead ≤0.5 mg/kg, arsenic ≤0.2 mg/kg, mercury ≤0.1 mg/kg (third-party SGS analysis), meeting EU and US supplement requirements.
Cold-water dispersible grade available – Allows direct incorporation into ready-to-drink beverages without emulsifiers, reducing production time and formulation cost.
Consistent batch-to-batch results – Each production lot is tested via HPLC and GC-MS for fatty acid composition; retention samples are kept for 3 years for traceability.

4. Application Scenarios
Memory and cognition supplements – A capsule manufacturer targeting adults over 50 can formulate high-dosage (300 mg) daily capsules to address age-related memory decline.Functional beverages – A beverage company producing focus drinks for office workers can use the cold-water dispersible grade to add cognitive support without altering clarity or mouthfeel.
Sports nutrition powders – A sports nutrition brand can mix the powder into pre-workout formulas to support neural adaptation under high physical stress and reduce training-related fatigue.
Private-label nootropics – A supplement brand building a private-label nootropic line can rely on standard purity to produce consistent, compliant products in large batches.
Allergy-conscious product lines – An e-commerce seller catering to soy-allergic consumers can launch a sunflower-sourced phosphatidylserine powder with a low-allergen label.
5. Common Questions (FAQ)
What is the purity of phosphatidylserine powder from this supplier?
The standard grade has ≥98% purity measured by HPLC. Each batch is released with a Certificate of Analysis showing exact assay results and impurity limits.
Is your phosphatidylserine made from soy?
No, the standard powder is produced from sunflower lecithin. This makes it free from soy antigens and suitable for people with soybean allergies.
What certifications does the production plant hold?
The production facility is ISO 9001 and ISO 22000 certified, and follows HACCP procedures. Third-party testing by SGS is performed on every batch.
Can I request a free sample for formulation testing?
Yes, we offer a 100 g free sample of standard grade powder for stability and compatibility tests. The sample ships within 2 business days via DHL.
What is the minimum order quantity (MOQ)?
MOQ is 1 kg for standard powder and 10 kg for the cold-water dispersible grade. For larger orders, we offer tiered pricing and freight adjustment quotes.
What is the current price per kilogram?
The FOB Qingdao price for sunflower-derived, ≥98% purity powder is $180–220 per kilogram, based on quarterly raw material costs and order volume.
What is the lead time after order confirmation?
Stocked items ship in 3–5 business days. Custom batch sizes or special grades take 10–15 days, including quality release testing.
Do you provide custom specifications or private label support?
Yes, we can adjust particle size, solubility profile, and packaging configuration. We also provide legal documents for supplement registration in the EU, US, and Southeast Asia.
6. Differentiation Summary
Unlike most suppliers that use soy-derived phosphatidylserine with purity levels between 70% and 90%, Lixing’s sunflower-based product maintains a confirmed ≥98% assay and heavy metal results that meet both USP and EU Pharmacopoeia thresholds. The cold-water dispersible option is uncommon among Chinese manufacturers and shortens formulation cycles for liquid dosage forms. This supplier is best suited for nutraceutical brand owners, beverage developers, and pharmacy distributors who prioritize allergen-free raw materials, verifiable testing data, and stable international supply logistics without holding large safety stock.
