Phosphatidylserine Supplier quotation
Time：2026-09-30Lixing supplies sunflower-derived phosphatidylserine powder, standardized to 20% assay by HPLC, for dietary supplement brands and research labs that need a reliable, allergen-free nootropic ingredient to support memory and cognitive function.
Core Selling Points
≥20% Phosphatidylserine (HPLC-verified) lets formulators hit label claims consistently without adding unnecessary phospholipid overage.Non-GMO sunflower lecithin source avoids soy allergens entirely, so the material is ready for hypoallergenic supplement lines and clean-label positioning.
Particle size ≥95% passing 80 mesh improves powder flow and blend homogeneity, which reduces tablet weight variation and capsule fill downtime.
Heavy metals meet USP limits – Pb ≤1.0 mg/kg, As ≤1.0 mg/kg, Cd ≤1.0 mg/kg – giving manufacturers confidence in daily-use supplement safety.
24-month shelf life under sealed storage at room temperature simplifies inventory planning and reduces write-off risk for ingredient buyers.

Data shown reflects the Lixing standard 20% sunflower PS grade. A 50% high-purity grade is also offered for targeted formulations.
Applicable Scenarios
Adult memory support supplements – Manufacturers formulating nootropic products for adults over 50 can add 100 mg PS per serving, a dose commonly used in cognitive decline studies.Sports nutrition recovery blends – Formulators targeting gym-goers use 300–500 mg PS per serving to help blunt exercise-induced cortisol elevations.
Children’s chewable products – Non-GMO sunflower origin avoids soy allergens, so pediatric supplement brands can use PS without cross-reactivity concerns.
Private label sourcing – A supplement brand launching a memory-skincare-nootropic line needs batch-level COAs, residual solvent data, and a stable supply agreement; Lixing provides these without requiring a full factory audit.
Research and clinical trials – 50% high-purity PS supports in-vitro or animal experiments where standardized phospholipid content is critical.
FAQ
1. Is Lixing's phosphatidylserine derived from soy or sunflower?
It is exclusively sunflower-derived. No soy lecithin is used in processing, so the final powder is soy-free and suitable for allergen-sensitive consumers.
2. What assay purity does this supplier offer?
The standard product has ≥20% phosphatidylserine by HPLC. A 50% high-purity grade is also available for formulators needing a more concentrated ingredient.
3. Does this powder dissolve in water for liquid shots or beverages?
Phosphatidylserine is lipophilic. It disperses but does not form a clear solution in water. It works best in capsules, tablets, softgels, or emulsified beverage formats.
4. What quality documentation can I receive with a sample?
Every batch includes a Certificate of Analysis covering HPLC assay, heavy metal content, microbial counts, residual solvents, and particle size. Allergen and GMO statements are also available.
5. Can Lixing blend PS with other nootropics like ginkgo or bacopa?
Yes. Under a mutual NDA, Lixing can produce custom premixes containing PS with botanicals or other actives, reducing your production steps and blending variability.
6. What is the minimum order quantity?
The MOQ for standard 20% PS powder is 25 kg. For first-time qualification, a 5 kg trial order is offered so formulators can pilot production without large commitment.
7. How should I store this ingredient to keep it stable?
Keep the container sealed, store below 25°C in a dry area, and avoid direct sunlight. Once opened, use within 30 days to prevent moisture pick-up.
8. Are there any solvents used in the extraction process?
Only ethanol is used during extraction. No hexane or other toxic solvents are involved, which meets food-safety expectations for clean-label supplements.
Differentiation from Other Phosphatidylserine Suppliers
Most phosphatidylserine suppliers switch between sunflower and soy lecithin based on raw material prices, which changes allergen profiles and phospholipid compositions between batches. Lixing maintains a single sunflower-sourcing model, so your finished product keeps the same hypoallergenic claim and consistent phospholipid matrix batch after batch. Unlike vendors that only offer 20% PS, Lixing also supplies 50% high-purity material and custom particle-size adjustments for gummies and chewables. The documentation package includes full phospholipid profiling and residual solvent reporting, giving formulators the data they need for regulatory submissions without guesswork. If your brand targets memory support, sports recovery, or pediatric products, this supplier offers a transparent, allergen-controlled PS supply route with verifiable quality metrics.
