Phosphatidylserine Purchase price
Time：2026-09-16Phosphatidylserine (PS) powder is a high-purity (>95% HPLC) cognitive health supplement ingredient derived from non-GMO sunflower (Helianthus annuus), designed for formulators and wholesale buyers to solve two core problems: raw material cost fluctuation and the high prevalence of soybean allergies among target consumers.
Core Selling Points
Purity above 95% (HPLC method): Allows a 100mg capsule specification to deliver the clinically studied reference intake of PS within a single unit, reducing filler volume and providing a solid evidence base for product claims.Sunflower-derived, not soybean-derived: Avoids soybean allergen concerns and GMO labeling disputes while maintaining a white to off-white powder appearance, suitable for allergy-sensitive markets in North America and Europe.
Complete flowability and compressibility data: A particle size distribution where 98% passes through an 80-mesh sieve enables capsule filling with a weight variation of within ±3% and direct compression into tablets with hardness above 80 N without a separate granulation step.
Optimized bulk procurement cost: Standard 25kg carton packaging, with the base unit price for orders above 100kg including domestic logistics to major ports. The quoted price contains no hidden customs clearance fees, and the price term can be locked for 90 days.

Application Scenarios
Memory vitality lines for the 40+ demographic: Directly encapsulated at 100mg per capsule, this powder supports stable working memory index measurements after an 8-week continuous intake cycle, substantiating memory-support advertising claims.Functional ready-to-drink beverages: Formulated at 100mg PS per 250ml bottle for office-worker cognitive endurance. With 0.2% lecithin as a suspending aid, the powder remains stably suspended for at least 4 hours without altering the liquid color value.
Double-blind clinical trial materials: For pilot-scale continuous production, this ingredient offers full batch traceability codes and an impurity fluctuation range strictly controlled between 95.0% and 96.8%, ensuring equivalent test materials across subject groups.
Cross-border e-commerce white-label supplements: Overseas sellers can use the provided CoA and batch-specific stability curves to support Amazon listings and streamline the FDA product registration documentation process for 90-count bottle exports.
FAQ
Q: What is the approximate purchase price per kilogram for PS powder?A: For standard container quantities of 500kg to 1 ton, the unit price is in the range of 100-150 RMB/kg including delivery to Shanghai port. Exact quotes require a formal inquiry and confirmation of order volume.
Q: Why is this product cheaper than certain imported brands?A: The process uses domestically sourced sunflower raw materials and an enzymatic conversion method instead of chemical hydrolysis, eliminating solvent recovery steps and reducing manufacturing costs by a direct 12% to 15% without secondary chromatographic purification markups.
Q: Is there significant purity variation between different batches?A: No. The internal quality control standard sets an upper limit of 96.8% and a lower limit of 95.0%, keeping inter-batch difference within 1.8 percentage points. Batch records are publicly accessible.
Q: How much does the purity drop after 24 months of shelf life?A: In sealed original packaging under 25°C/60% RH conditions, the typical purity decrease is 1.5% of the initial content after 24 months, still remaining above the 90% label claim requirement.
Q: Will there be capping or lamination issues when directly compressing tablets?A: Direct compression works. Adding 20% microcrystalline cellulose PH102 and 5% crospovidone produces tablets with hardness between 80-110 N and friability below 0.8% using a 12mm flat punch.
Q: Is this powder compatible with vitamin B complex in a blended module?A: Yes. Accelerated stability testing over 6 months at 40°C with vitamins B1, B6, and B12 showed retention rates of 98.6%, 99.2%, and 97.4% respectively, with no brownish discoloration observed.
Differentiation Summary
Most competing PS raw materials on the market are extracted from soybeans, which requires additional chromatography steps to remove soybean isoflavone residues, pushing up procurement prices. This product, by contrast, uses a sunflower source and a targeted enzymatic process to bypass those byproduct treatment costs. As a result, it achieves a purchase price reduction of 15% to 20% compared to imported equivalents at the same >95% purity grade (based on a cross-analysis of export average prices in Q4 2024). This ingredient best suits growing brands that want to secure mid-to-low price positioning without compromising quality thresholds or altering existing label declarations. The full-batch traceability system established by Lixing ensures a seamless transition from trial runs to bulk production without gaps.
