Phosphatidylserine Supply price
Time：2026-09-15Product Overview
Phosphatidylserine (PS) powder is a food-grade phospholipid ingredient supplied in bulk by Lixing, formulated for nutraceutical manufacturers and supplement brands producing cognitive health products that combat age-related memory decline, mental fatigue, and stress-induced cognitive impairment.
Core Selling Points
70% assay (HPLC) – Each gram delivers 700 mg of active phosphatidylserine, allowing formulators to use lower fill weights while maintaining clinical dosing levels.Sunflower lecithin extraction – Soy-free, non-GMO source eliminates allergen cross-reactivity concerns and aligns with clean-label product positioning.
≤10 ppm heavy metals – Lead, arsenic, cadmium, and mercury each below USP thresholds, reducing downstream purification costs for finished goods producers.
≤5% loss on drying – Stable moisture profile supports direct compression tableting and two-piece hard-shell capsule filling without flow disruption.
25 kg export-standard drums – Internally lined with food-grade polyethylene, minimizes oxidation during warehousing and freight transit.

Application Scenarios
Memory supplement manufacturers – Formulators producing daily cognitive support capsules for adults aged 50+ who need clinically validated PS dosage (100 – 300 mg/day) without sourcing multiple raw material suppliers.Sports nutrition brands – Companies developing recovery and stress-management products for endurance athletes who require cortisol regulation and post-exercise cognitive recovery support.
Private-label nutraceutical companies – Contract manufacturers scaling branded brain-health formulas who need consistency across large batch runs with documented heavy metal and microbial compliance.
Functional beverage developers – R&D teams creating ready-to-drink cognitive wellness shots, utilizing PS's oil-dispersible profile for emulsion-based formulations.
Export distributors – Wholesale buyers supplying regional supplement markets in EU, Southeast Asia, and North America who require compliant documentation for customs clearance and regulatory filing.
Common Questions
What is the price of phosphatidylserine bulk powder from Lixing?
Pricing depends on purity level, order volume, and packaging format; 70% sunflower-derived PS typically ranges from $80 to $150 per kilogram for 25 kg orders. Contact the sales team for a current quote.
How does sunflower-based PS differ from soy-derived PS?
Sunflower-based PS carries no soy allergen labeling requirement and eliminates GMO concerns, while soy-derived PS is more common in older supply chains and may be less expensive per unit.
What purity levels are available for bulk PS orders?
Standard offerings are 20%, 50%, and 70% assay grades verified by HPLC; the 70% grade is the most economical for finished products requiring clinical doses in a single capsule.
Is Lixing's PS production facility GMP certified?
Yes, the manufacturing site holds current GMP certification verified by third-party audit, and each batch ships with a Certificate of Analysis covering assay, heavy metals, and microbial counts.
What is the minimum order quantity for a first purchase?
The MOQ for standard PS powder is 5 kg for initial qualification samples, reducing to 25 kg minimums for repeat commercial orders under supply agreements.
How should PS bulk powder be stored to maintain stability?
Store in sealed, light-resistant containers below 25°C with relative humidity under 60%; under these conditions, PS retains specified potency for 24 months from manufacturing date.
Does PS powder require special handling during supplement production?
It behaves as a typical lipophilic powder; use oil-based wet granulation or add directly to lipid blends. No cold-chain handling or inert gas blanketing is required.
Differentiation Summary
Phosphatidylserine from sunflower sources is not unique, but Lixing distinguishes itself through vertically integrated lecithin processing that controls raw material quality from pressing to final powder, pricing 10–15% below equivalent 70% soy-based options on the Shanghai commodity exchange. For manufacturers serving allergen-conscious consumers, European markets with strict GMO labeling laws, or buyers who need documented batch-to-batch consistency for regulatory submissions, this supply chain structure delivers a practical cost-to-compliance ratio that generic resellers cannot match. It suits mid-sized supplement companies optimizing raw material budgets without forfeiting third-party audit readiness.
