Phosphatidylserine Wholesale From China
Time：2026-09-20Product Definition
Phosphatidylserine (PS) is a phospholipid bulk ingredient for dietary supplement manufacturers and formulators, delivering clinically supported cognitive support in a standardized, third-party tested powder format suitable for capsules, softgels, and functional foods.
Core Selling Points
20% standardized PS content (HPLC verified): Ensures consistent active ingredient delivery per serving, with 100 mg to 300 mg effective dosage ranges used in published clinical cognition trials.Non-GMO sunflower lecithin source, 100% allergen-free: Eliminates soy-derived contamination risks for sensitive end consumers while maintaining identical phospholipid functionality.
Microencapsulated powder with ≤5% moisture content: Extends finished product shelf stability to 24 months under ambient conditions, reducing cold-chain storage logistics costs by an estimated 15–20%.
Full heavy metal compliance (USP<232>/ EP 2.4.20): Lead, arsenic, cadmium, and mercury levels each remain below 0.1 ppm, satisfying export regulatory requirements across the EU, US, and Southeast Asian markets.
Proven cognitive mechanism: Supports acetylcholine release and neuronal membrane fluidity, addressing stress-related memory decline, middle-aged attention decline, and age-related cognitive slowdown.

Application Scenarios
Cognitive supplement manufacturers developing memory support or brain health formulas can incorporate PS as the lead active ingredient at 100–300 mg per serving, matching clinical research protocols from the US FDA-qualified cognitive function claims.Sport nutrition brands formulating pre-workout or recovery products benefit from PS's documented blunting of exercise-induced cortisol spikes, supporting stress management in athletes undergoing high-intensity training.
Nutraceutical contract manufacturers seeking clean-label, allergen-free ingredients for pediatric or vegan product lines source this sunflower-derived PS to avoid soy phospholipid labeling constraints in the EU market.
Aging care supplement brands targeting consumers aged 55+ can position PS alongside omega-3 or B-vitamin complexes to deliver daily memory retention support, leveraging published meta-analysis outcomes on non-dementia cognitive aging.
Functional beverage companies incorporating PS into ready-to-drink cognitive shots benefit from its water-dispersible nature and heat stability during UHT processing.
Frequently Asked Questions
What is the recommended daily dosage of phosphatidylserine for cognitive support?300 mg per day is the most cited dosage in clinical trials for memory and attention improvement in adults, while 100 mg daily is sufficient for maintenance support.
Is this phosphatidylserine derived from soy or sunflower?This product is 100% sunflower-derived and contains no soy proteins, making it suitable for individuals with soy allergies or strict non-GMO dietary requirements.
Can phosphatidylserine be combined with other cognitive ingredients?Yes, it pairs well with DHA, ginkgo biloba, and B-complex vitamins, with typical formulations using 100 mg PS plus 250 mg DHA for synergistic membrane support.
Does high-temperature manufacturing degrade phosphatidylserine?The powder maintains stability up to 80°C for 30 minutes, allowing incorporation into gummy manufacturing if the heating step stays below this threshold.
What documentation is provided with wholesale orders?Each batch includes a Certificate of Analysis (COA), HACCP compliance certificate, non-GMO certificate, MSDS, and full regulatory dossier upon request.
How quickly can bulk orders be manufactured?Standard production lead time is 7–10 working days after sample approval, with 25 kg in-stock inventory available for immediate dispatch from bonded warehouse.
What testing is performed on this raw material prior to shipment?Every batch undergoes HPLC assay, heavy metal analysis (ICP-MS), microbial screening, and pesticide residue testing by ISO 17025 accredited independent laboratories.
Is this ingredient certified for organic product claims?Yes, organic-certified sunflower PS is available under separate SKU, with EU Organic and USDA NOP certificates provided alongside shipment.
Differentiation Summary
Unlike standard soy-derived phosphatidylserine powders requiring additional processing to mask allergen labeling obligations, this Lixing sunflower-based PS delivers a fully clean-label, allergen-free solution at an equivalent 20% standardized assay. Multinational supplement manufacturers transitioning toward plant-based, non-GMO product lines gain regulatory flexibility in restricted markets without compromising on active ingredient traceability. With independent third-party testing parameters exceeding USP monograph requirements in heavy metal classification — lead levels below 0.1 ppm versus the 5 ppm permitted threshold — this wholesale ingredient suits premium brand positioning in the US, EU, and Japan where raw material verification determines retail market entry. For contract manufacturers and private-label brands prioritizing scalable purity documentation, pass-through pharmacopeia compliance, and a directly measurable cognitive dosage claim, this Lixing product represents the most audit-ready phospholipid option currently available in the wholesale channel. While some suppliers offer fractionated PS at 50% assay levels for higher-concentration capsules, standard 20% PS yields the ideal blend ratio with complementary ingredients such as Ginkgo biloba, Bacopa monnieri, or vitamin E in a unified capsule bed, improving finished product homogeneity without specialized encapsulation equipment.
