Phosphatidylserine 51446-62-9 Marke Quotation
Time：2026-10-301. Product Definition
This phosphatidylserine bulk powder from Lixing, a China-based manufacturer, is a sunflower-lecithin-derived ingredient with a verified assay of ≥98% by HPLC, designed for dietary supplement and functional food producers that need consistent quality, full compliance documentation, and a dependable supply chain.
2. Key Selling Points
Purity ≥98% by HPLC – Allows formulators to use smaller dosages while maintaining cognitive-support claims, reducing overall production cost per finished capsule.Sunflower-lecithin origin – Provides a soy-free, non-GMO source that suits hypoallergenic and vegan product lines without cross-contamination risks.
Batch-to-batch consistency – Every lot is tested for assay, residual solvents, and heavy metals by in-house HPLC and GC; results are attached as a sealed certificate of analysis with each shipment.
Stable flowability – 80-mesh particle size achieves a ≥90% passing rate, ensuring uniform blending in capsule filling and tablet pressing operations without segregation.
Full documentation package – Offers HACCP, ISO 9001, and Halal certificates, plus third-party analysis reports (e.g., SGS) to support product registrations in the US, EU, and Southeast Asia.

4. Applicable Scenarios
Pre-workout and high-stress formulations – Sports nutrition brands use PS powder to reduce exercise-induced cortisol spikes and support mental focus through intense training cycles.Brain-health supplements for aging populations – Manufacturers targeting memory support add this PS powder to capsule blends for late-middle-aged and elderly consumers.
Functional gummies and chewable tablets – Product developers rely on the low heavy-metal profile and stable particle size to maintain uniform dosing and taste masking.
Beverage premixes – RTD and powder-beverage brands incorporate this ingredient because of its fine mesh and controlled moisture level, which prevents clumping during mixing.
Clean-label formulations – Organic and natural brands use sunflower-derived PS to launch allergen-conscious products without soy concerns.
5. Frequently Asked Questions
What is the minimum order quantity for this phosphatidylserine powder?
For standard phosphatidylserine powder, the minimum order quantity is 10 kg. A 100 g sample is offered for quality inspection prior to purchase. For first-time clients, we can include the sample with a pilot order to evaluate blending performance without a separate shipping fee.
Is this product made from soy or sunflower lecithin?
This product is made exclusively from sunflower lecithin, which means it is naturally soy-free and non-GMO. Because the raw material is sunflower-based, the powder suits consumers with soy allergies and supports vegan or vegetarian product labels without cross-contamination concerns.
How can I verify the purity of each batch?
Every production batch is tested by high-performance liquid chromatography (HPLC) for assay and by ICP-MS for heavy metals. The batch certificate of analysis (COA) is included in the shipment and also available on our client portal. You can request a COA sample before ordering.
Do you have certificates like ISO or Halal?
Our manufacturing facility holds ISO 9001, HACCP, and Halal certifications. These certificates are available for download or as hard copies upon request during the supplier audit process. Third-party reports from SGS or equivalent labs can be arranged in your product specification packet.
What is the lead time after we place an order?
For standard orders below 100 kg, production and shipping take 15 to 20 working days after payment confirmation. For larger quantities, the lead time extends to 30 days, depending on the container schedule and whether the product requires custom packaging. We provide an exact delivery window in the proforma invoice.
Does the powder have any noticeable taste or odor?
The powder has a characteristic light lecithin smell and a mild taste that is typical of sunflower-derived phospholipids. It contains no added flavors or masking agents. In finished products, the sensory impact is negligible at the recommended dosage of 100–300 mg per serving.
Can you provide a sample before bulk purchase?
Yes. We provide a 100 g sealed sample at a nominal cost, which is refundable with the first bulk order. The sample batch is not a special production run, so the quality reflects the actual commercial batches you will receive.
How long is the product shelf life?
The shelf life is 24 months from the date of manufacture when stored below 25°C in an unopened, sealed container. After opening, keep it tightly closed and protect it from humidity, sunlight, and elevated temperatures to preserve the assay.
6. Differentiation Summary
Unlike many bulk ingredient suppliers that offer either low price or formal documentation, this product combines three elements useful for regulated markets: a verified ≥98% assay by HPLC, sunflower-based raw material for allergen labeling, and a full documentation package from a China-based manufacturer. It is best suited for supplement brands that export through retail channels where quality audits are routine. Lixing positions its supply as a middle-ground alternative to lower-grade Chinese powders and high-cost European lecithin products, offering consistent quality with practical MOQs and faster regional logistics.
