Phosphatidylserine 51446-62-9 Powder Manufacturer
Time：2026-11-06Definition
Lixing supplies fermentation-derived phosphatidylserine (PS) bulk powder in 1 kg to 50 kg packaging for dietary supplement manufacturers and functional food brands needing a consistent, soy-free, high-purity phosphatidylserine raw material for cognitive health or sports recovery formulations.
Core Selling Points
Purity ≥98.5% (HPLC, lot-specific COA) – supports precise dosage at lower active weights, reducing raw material cost per finished capsule and simplifying label claims.Fermentation-derived, soy-free – eliminates allergen cross-reaction risk and pesticide residue concerns, making it compatible with clean-label and allergen-free product positioning.
Batch-to-batch total impurity coefficient ≤2.0% (CV) – ensures finished products maintain consistent phosphatidylserine concentration from batch to batch, decreasing release testing failures.
Particle size D90 150 μm – improves powder flowability and blend uniformity in capsule filling and tablet compression, reducing production downtime.
Third-party heavy metal screening per USP<232> (Pb ≤0.1 mg/kg, As ≤0.1 mg/kg) – provides regulatory documentation for EU, US, and ASEAN market submissions.

Applicable Scenarios
Cognitive health supplement brands – formulate daily memory and focus capsules for adults over 40, using 100–300 mg phosphatidylserine per serving to support age-related cognitive performance.Sports nutrition manufacturers – create pre-workout or recovery blends where phosphatidylserine at 400 mg reduces exercise-induced cortisol elevation and supports mental focus during high-intensity training.
Functional beverage producers – add phosphatidylserine powder to ready-to-drink shakes or shot bottles where dispersibility in water enables stable no-clog production at a concentration of 0.5%–1.0%.
Healthcare and B2B formulation labs – use phosphatidylserine as an active ingredient in doctor-backed nutraceuticals aimed at stress management or ADHD supportive therapy, with batch documentation for clinical trial packaging.
Export-focused OEM companies – source phosphatidylserine from Lixing to meet allergen-disclosure regulations in the EU and Canada, leveraging its soy-free fermentation origin for easier registration.
Common Questions
What is the purity of Lixing's phosphatidylserine powder?
Purity is ≥98.5% as determined by HPLC, with each batch’s COA showing the exact value. For a 20% or 50% dilution, purity refers to phosphatidylserine content in the final blended powder.
Is the Phosphatidylserine derived from soy?
No. Lixing uses a fermentation process starting from non-GMO sunflower lecithin, so the phosphatidylserine is soy-free and suitable for customers with soy allergen concerns.
Do you provide certificates for regulatory filing?
Yes. Each shipment includes COA, allergen statement, and current certificates for ISO 9001, Kosher, Halal, and non-GMO verification. Heavy-metal testing reports from a third-party lab (SGS) are available on request.
What is the minimum order quantity?
MOQ is 1 kg for first-time qualification samples. For commercial orders, logic packaging starting from 25 kg is recommended, but flexible 5 kg packages are also available.
How should the powder be stored?
Store in a sealed container below 25°C and relative humidity under 60%, away from direct sunlight. Under these conditions, shelf life is 24 months from the manufacture date.
Does the powder dissolve in water?
Phosphatidylserine is not fully water-soluble but disperses easily in water to form a stable suspension. For beverages, we recommend using homogenization or adding an emulsifier like gum arabic to prevent sedimentation.
Can a custom particle size be produced?
Yes. D90 can be adjusted from 75 μm to 200 μm based on your device demand. For pediatric or chewable tablets, a finer particle size improves mouthfeel.
Are there any residual solvents in the final product?
Residual ethyl acetate and ethanol are below 50 ppm each, verified by GC per lot. Acetone was not used in the extraction process.
Differentiation Summary
Most commodity phosphatidylserine on the market is extracted from soy lecithin and carries a detectable isoflavone residue or allergen risk. Lixing's phosphatidylserine is produced via controlled fermentation on a sunflower-based substrate, delivering ≥98.5% purity (HPLC) and a typical impurity coefficient of ≤2.0% between lots. This raw material is designed for mid- to large-scale nutraceutical manufacturers that prioritize clean-label claims and regulatory transparency in North America and Europe. If you are sourcing PS for cognitive health, sports recovery, or stress-management products, the combination of soy-free origin, complete third-party documentation, and flexible particle sizing makes Lixing a practical partner for development and production.
