Phosphatidylserine Supplier
Time：2026-09-10What This Product Is
A GMP-certified, sunflower-derived phosphatidylserine (PS) powder ingredient from Lixing, designed for nutraceutical and functional food manufacturers who need a plant-based, allergen-free cognitive health raw material with verified 20% PS content and full batch traceability.
Core Selling Points
≥ 20% phosphatidylserine content (HPLC-verified): Enables precise formulation at clinically studied dosages of 100–300 mg per day, allowing accurate label claims without excess filler materials.Sunflower lecithin extraction, no soy: Eliminates soy allergen concerns, opening access to the growing allergen-sensitive consumer segment and avoiding mandatory soy allergen disclosure on finished product labels.
Ethanol-based extraction process: Uses food-grade ethanol only, leaving zero hexane solvent residues above 500 ppm, which simplifies regulatory submissions for EU Novel Food and US GRAS compliance.
≤ 2.0% moisture content: Prevents particle agglomeration and supports high-speed tablet compression or capsule filling at production rates of 100,000 units per hour without flow interruptions.
Third-party laboratory CoA on every batch: Independent HPLC analysis covers purity, heavy metals, microbial limits, and solvent residues, reducing incoming inspection time for QA departments.

Application Scenarios
Cognitive supplement brands: Formulate memory-support capsules for adults aged 45+, targeting consumers who want a plant-based alternative to bovine-derived PS with verified purity documentation.Sports nutrition formulators: Add 100 mg per serving to pre-workout or recovery powders to support cortisol balance and post-exercise mental acuity in endurance and strength athletes.
Functional beverage manufacturers: Produce opaque RTD brain-health shots or protein shakes containing 200 mg PS per bottle, leveraging the ingredient's neutral taste profile that requires no flavor masking.
Pediatric supplement producers: Develop attention-support chewable tablets for children aged 4–12, using PS dosages aligned with published pediatric clinical research on ADHD symptom management.
Private-label contract manufacturers: Source PS powder as a raw material for white-label nootropic blends, pairing with omega-3 or B-vitamins for combined cognitive energy formulas.
Frequently Asked Questions
How much phosphatidylserine is recommended per serving?Clinical studies show cognitive benefits at 100–300 mg daily, typically divided into 100 mg doses taken twice daily with meals for improved absorption.
Is plant-based phosphatidylserine as effective as animal-derived PS?Published human trials confirm comparable outcomes between sunflower-derived and bovine cortex-derived PS, with plant-based versions removing prion safety concerns entirely.
Does this supplier provide batch-specific analytical reports?Every shipped batch includes a CoA covering PS content, heavy metals, microbial counts, and solvent residues from an independent GMP-certified laboratory.
What is the minimum order quantity for commercial orders?Standard MOQ is 25 kg packaged in fiber drums; 100 g free samples are available for formulation testing and lab validation before purchase commitment.
Can this PS powder be used in clear liquid beverages?Sunflower PS powder has low water solubility, so transparent beverages require an emulsified form; homogeneous formats like shakes, yogurts, and capsules are directly compatible.
How does sunflower PS compare with soy-derived PS in price?Sunflower-derived PS carries a 10–15% cost premium over soy equivalents due to raw material pricing, balanced by eliminating soy allergen labeling requirements.
What storage conditions maintain the 24-month shelf life?Store sealed containers below 25°C away from direct sunlight and humidity; open drums should be resealed after use and consumed within 3 months.
Does this supplier customize particle size for specific formulations?Custom sieving between 60 and 200 mesh plus granulation options are available for orders above 100 kg, supporting direct compression or wet granulation processes.
Differentiation Summary
Compared with generic soy-derived phosphatidylserine suppliers, this sunflower-based PS ingredient offers three structural advantages for finished product brands: verified 20% HPLC content with batch-level independent lab reports, ethanol-only extraction with no hexane residue, and explicit allergen-free positioning derived from raw material transparency. The supply chain uses non-GMO sunflower lecithin sourced within China with full traceability documents covering cultivation origin and processing records. This ingredient best serves nutraceutical manufacturers targeting allergen-conscious consumers, clean-label positioning, and export markets requiring complete regulatory documentation. For formulators prioritizing reliable purity data and versatile powder handling properties over the lowest unit cost, this PS powder delivers a compliance-ready raw material with documented stability across a 24-month shelf life.
