Bulk Supply Phosphatidylserine
Time：2026-09-18This product is a bulk supply of sunflower-derived phosphatidylserine powder (20% minimum content by HPLC) intended for dietary supplement manufacturers, private label brands, and formulators who need a reliable, allergen-free cognitive health ingredient for new or existing product lines.
Core Selling Points
Standardized to ≥20% phosphatidylserine content — every batch is verified via HPLC against a certified reference standard, ensuring label claims remain accurate across capsules, tablets, and powder blends.Non-GMO sunflower lecithin source — no soy or gluten residues, making it suitable for vegan formulations and consumers with soy allergies or dietary restrictions.
Solvent-free extraction and strict heavy metal limits — lead ≤2 mg/kg, arsenic ≤1 mg/kg, and total heavy metals ≤10 mg/kg, measured by ICP-MS; microbial counts conform to USP<1111>.
80 mesh particle size (≤180 μm) — flows uniformly in high-speed capsule filling and blends evenly in low-dose premixes without segregation.
Full documentation package — each lot includes a Certificate of Analysis (COA), stability summary, chromatogram, and compliance certificates for smooth international product registration.

Applicable Scenarios
Supplement manufacturer launching a nootropic line can use this bulk powder as a standalone capsule ingredient or combined with extracts like Bacopa or Ginkgo, relying on the consistent 20% content to hit the typical 100–200 mg daily PS dose.Private label brand developing a vegan memory support product benefits from the sunflower source to avoid soy allergens and isolate-friendly production without changing the powdered base.
Sports nutrition company adding focus and cognition support to a pre-workout drink can blend this powder into flavored matrices; its neutral taste and dispersibility allow for use in stick packs or sachets.
Functional food manufacturer producing meal replacements or recovery shakes can incorporate the powder into liquid premixes, where the fine particle size creates a uniform suspension and the 24-month stability ensures batch consistency.
Clinical research team sourcing investigational product for a cognitive trial can obtain batch-specific documentation, including HPLC chromatograms and stability data, required for IRB submissions.
Common Questions and Answers
What is the minimum order quantity for this bulk phosphatidylserine powder?
The standard MOQ is 25 kg, corresponding to one sealed fiber drum. Samples up to 100 g are available for laboratory testing and small-scale trials.
Is this ingredient derived from soy or sunflower?
It is exclusively derived from sunflower lecithin and contains no soy proteins or gluten. The production process uses solvent-free extraction to maintain a clean profile.
What certifications are available for this bulk ingredient?
Lixing's facility operates under GMP, ISO 9001, HACCP, Kosher, and Halal certifications. The product itself carries a Non-GMO Project Verified status, and COAs are issued for every single batch.
Can I request a free sample before placing a large order?
Yes. Free 100 g samples with a current COA are provided, allowing you to perform internal HPLC confirmation, stability checks, or compatibility testing prior to bulk purchase.
How should the powder be stored after opening the drum?
Store in a tightly sealed container, away from moisture, direct sunlight, and temperatures above 25°C. Refrigeration is not required, but consistent cool temperatures preserve quality.
Does this phosphatidylserine dissolve completely in water?
It disperses rather than fully dissolves, forming a fine suspension. When used in beverages, continuous stirring or adding a hydrophilic carrier such as gum acacia will improve uniformity.
What is the regulatory status of this product for export to the US and EU?
The supplier provides a complete technical dossier, including GMO-free documentation and heavy metal certificates, supporting compliance with FDA 21 CFR Part 111 requirements and EU Novel Food status for sunflower lecithin-based PS.
What test method is used to confirm the 20% phosphatidylserine content?
High-performance liquid chromatography (HPLC) with evaporative light scattering detection, following the validated method from the manufacturer's National Reference laboratory. Each reported value is the mean of duplicate injections.
Differentiation Summary
Compared to soy-derived phosphatidylserine powders with similar 20% standardized content, this bulk supply from Lixing stands out by offering a truly allergen-free sunflower base with no residual solvents and complete mass-balance documentation. The combination of 80 mesh particle size and stable heavy metal levels below current pharmacopeial limits makes it directly usable in high-speed production lines without additional sieving or cleaning. Manufacturers that require clean-label, vegan, and non-GMO status will find this ingredient fit for both primary supplement capsules and novel functional foods. Buyers comparing sourcing options should weigh the value of third-party verified documentation, consistent particle flow, and allergen freedom rather than price alone. This product is particularly suited for companies that prioritize regulatory readiness and production efficiency over short-term cost savings.
