Common Q&A
What is the minimum order quantity for this phosphatidylserine powder?
The minimum order quantity (MOQ) is one drum, which equals 25 kilograms of phosphatidylserine powder. For quality assessment, we offer sample packets of 1 kilogram at a nominal fee; the sample fee is fully credited toward the purchase of 100 kilograms or more. This policy helps buyers test compatibility before committing to a large volume.
Is this product derived from soy or sunflower?
This product is extracted from non-genetically modified sunflower lecithin. It contains no soy protein residues, making it an excellent option for consumers with soy allergies or those who prefer a vegetarian and vegan-friendly supplement. The sunflower source also reduces the risk of pesticide residue commonly associated with conventional soy crops.
How does your supply price compare to other phosphatidylserine suppliers?
As a vertically integrated manufacturer, we sell directly to buyers without intermediary commissions, providing a price advantage that can be confirmed in our quotation. The final price is determined by order volume, purity grade, and ongoing raw material costs. Contact us with your target quantity and destination to receive a transparent cost breakdown within 24 hours.
Do you provide third-party test reports?
Yes, each production batch is sent to an ISO 17025-accredited laboratory for independent analysis, covering assay, heavy metals, microbial limits, and solvent residues. A certificate of analysis (COA) is issued with every shipment. The test method follows HPLC and ICP-MS procedures, and results are archived for at least five years for regulatory inspections.
What is the shelf life and storage recommendation?
The shelf life is 24 months from the manufacturing date when stored in an unopened, original container under cool, dry conditions below 25°C (77°F). Avoid exposure to direct sunlight and high humidity. Once opened, it should be used as soon as possible and re-sealed tightly after each use to prevent moisture absorption.
Can this powder be used directly in vegetable capsules?
The powder has a particle size of 98% through 80 mesh, which gives good flowability and compaction behavior. It can be encapsulated with a standard dosator nozzle without additional coating or excipients. However, if your formulation requires faster dissolution, we recommend mixing with a small amount of magnesium stearate as a lubricant.
Are Halal and Kosher certificates available?
Yes, our manufacturing facility holds Halal and Kosher certifications, and each batch can be accompanied by the corresponding certificate depending on your destination market. We also offer Non-GMO Project Verified documentation upon request. Please specify your certification requirements at the time of ordering to include them in the delivery document package.
Differentiation Summary
Compared with many soy-derived phosphatidylserine products available in the market, this sunflower-based powder offers a clear advantage in avoiding common allergens and GMO concerns while maintaining a standardized 50% assay. Lixing’s direct control over the production process allows for stable supply, competitive pricing, and full traceability—making it the practical choice for mid-to-large supplement brands that prioritize safe ingredients and predictable costs.
