Phosphatidylserine Exporter
Time:2026-09-17Product Overview
Lixing Phosphatidylserine (PS) 40% is a sunflower-derived bulk phospholipid powder, standardized by HPLC to 40% purity, designed for supplement manufacturers and exporters that formulate cognitive-support products requiring strict allergen control, defined batch specifications, and documented quality data for international registration.
Core Selling Points
One batch, one standard: HPLC assay of 40.0% ± 2.0% per batch. A supplement maker can set a label claim of 100 mg PS without adding overage to cover raw material variation. At a 40% concentration, 250 mg of powder delivers a 100 mg PS serving, leaving room in the capsule formula for additional ingredients.
Sunflower lecithin base, not soy. The production line handles no soy material at any stage, meaning no isoflavone residues, no GMO documentation burden, and no soy allergen warning required under EU Regulation 1169/2011.
Residual solvent levels below pharmacopeia thresholds. The process uses phospholipase A2 conversion instead of n-hexane extraction. Typical n-hexane residues stay under 290 ppm and ethanol under 500 ppm.
Every lot ships with a full COA file. The documentation includes HPLC assay, 31P-NMR structure confirmation, heavy metals by ICP-MS, microbial counts, and water activity. Importers receive the data needed for US FDA facility checks and EU customs reference in one package.
Order sizes fit both R&D and production stages. A 1 kg nitrogen-flushed foil bag covers formulation pilot runs; 10 kg and 25 kg drum options support first commercial batches without forcing a large purchase commitment.

Suitable Applications
Memory and focus supplements for adults aged 50+ — 100–300 mg PS per daily serving fits a small capsule and supports label claims without soy allergen declarations.
Sports nutrition formulas for mental endurance — a pre-workout or recovery powder incorporating 100 mg PS per scoop addresses the demand for cognitive performance during high-intensity training.
Nootropic stacks for students and professionals — the 40% concentrate allows a compact formulation that combines PS with L-theanine or Bacopa while keeping tablet weight under 600 mg.
Private-label brain-health brands entering EU or US markets — documented batch data, non-GMO status, and sunflower sourcing simplify the technical file for a product launch, including Prop 65 assessments.
R&D laboratories and university research teams — the 1 kg package size supports pre-clinical feeding studies and stability trials without excessive inventory.
FAQ
What dosage of phosphatidylserine is commonly used in commercial supplements?
Clinical studies usually test 100–300 mg per day. Most finished products supply 100 mg per capsule, while higher-dose sports formulas use 200 mg. With 40% powder, a 100 mg PS serving requires 250 mg of raw material.
Is Lixing phosphatidylserine derived from soy or sunflower?
Sunflower. The starting material is sunflower lecithin, converted by phospholipase A2. The facility processes no soy on the same line, so the powder carries no soy protein residues and does not require soy allergy labeling.
What documents are included with each batch?
Each shipment includes a Certificate of Analysis with HPLC assay, ICP-MS heavy metals, microbial results, residual solvents, and 31P-NMR confirmation. A technical data sheet, safety data sheet, and allergen declaration are supplied as well.
Can a buyer request a free sample before placing an order?
Yes. A 50 g sample from the current production lot is available at no charge; the buyer covers freight. The sample ships with the corresponding COA values so testing results relate to the actual batch offered.
What is the minimum order quantity for a trial batch?
Standard MOQ is 10 kg. That amount yields roughly 40,000 capsules at 100 mg PS per capsule, which is enough to test the market. The 1 kg sample format is also available for laboratory-level work.
Is this ingredient suitable for vegan product lines?
Yes. The powder comes entirely from plant-based sunflower lecithin, with no animal-derived enzymes or excipients used. The production facility holds Kosher and Halal certification as well.
Does the powder perform well in tablet compression?
It compresses reliably. The bulk density range of 0.35–0.50 g/mL supports uniform die filling, and 95% passage through an 80 mesh sieve prevents segregation in direct compression blends. Dry granulation is recommended if PS concentration exceeds 30% of the tablet formula.
How does sunflower-derived PS compare with soy-derived PS in quality?
Both forms share the same chemical structure of phosphatidylserine. Sunflower PS offers a cleaner allergen profile and requires no GM status documentation. Soy PS tends to be less expensive, but it adds labeling complexity for EU and US retail markets.
Differentiation
Most bulk PS suppliers sell a soy-based 20% concentrate or offer an unstandardized phospholipid blend with wide assay tolerances. Lixing concentrates on a single specification: sunflower PS at 40% with a narrow ±2% assay window and full batch documentation. That combination suits brands aiming for international distribution where soy allergen declarations, GMO paperwork, or unstable assay values would otherwise delay registration. Buyers looking for a raw material that passes compliance review, reduces formula calculations, and keeps capsule sizes small will find this product ready for scale-up.
