high-purity source of phosphatidylserine
Time：2026-10-08Lixing Phosphatidylserine is a standardized bulk nootropic ingredient for supplement manufacturers, private-label formulators, and functional food producers who need a consistent, high-purity source of phosphatidylserine (PS) for memory-support and cognitive-health products.
Core Selling Points
20% phosphatidylserine content (HPLC verified) – Each gram of powder delivers exactly 200 mg of pure PS, allowing precise dosing in softgels, capsules, or tablets without overfilling.Sunflower lecithin extraction – Free from soybean allergens and animal-derived components, making it suitable for vegan, allergen-free, and kosher-certified product lines.
Full compliance documentation – Every batch is tested for heavy metals, microbial contamination, and residual solvents; a Certificate of Analysis (COA) is issued with each shipment.
Low hygroscopicity and good flowability – Powder remains stable in high-humidity blending environments and produces consistent tablet weight during high-speed compression.
Sacha inchi or sunflower origin options – Flexible sourcing to match your label claims for non-GMO and botanical-derived nootropics.

Applicable Scenarios
Mood and cognitive supplement brands – A manufacturer formulating daily memory-support capsules for seniors uses this bulk PS to create a standardized 100 mg per serving product without batch-to-batch variation.Sports nutrition companies – A brand building a recovery formula for athletes adds phosphatidylserine to reduce exercise-induced cortisol spikes, leveraging the allergen-free sunflower source for clean-label marketing.
Vegan nutraceutical lines – A producer of plant-based supplements replaces soy-derived PS with this sunflower lecithin-based ingredient, avoiding soy allergen declarations and maintaining a vegan certification.
Functional food developers – A smoothie powder manufacturer incorporates the low-hygroscopic PS powder into a dry blend, ensuring consistent distribution and no caking during processing.
Private label distributors – A white-label supplier stocks this PS ingredient to serve multiple clients with different dosage strengths, relying on the COA to provide accurate label amounts.
Frequently Asked Questions
What is the exact purity of your phosphatidylserine?Our standard bulk PS powder contains 20.0% phosphatidylserine as confirmed by HPLC analysis. Higher purity (50%) can be produced on a custom contract basis.
Do you offer samples for formulation testing?
Yes, free 500 g samples are available for qualified buyers. Samples are shipped with a complete COA, and the stability data covers three months under accelerated conditions.
How do you ensure batch-to-batch consistency?
Every production lot is tested in-house using the same HPLC method, plus third-party verification on a full spectrum of heavy metals and microbes. Only batches within ±0.5% of the labeled assay are released.
Is this phosphatidylserine suitable for vegan products?
Yes. The ingredient is made exclusively from sunflower lecithin and does not contain any animal-derived components. It is also free from soy and gluten.
What is the minimum order quantity (MOQ)?
Standard MOQ is 25 kg for the 20% PS grade. For longer production runs, we offer volume-based price breaks at 100 kg, 500 kg, and 1 metric ton.
Can you supply regulatory documents for FDA or EU submissions?
Yes. Alongside the COA, we provide the manufacturing flowchart, stability summary, and a letter of access for the facility’s GMP certificate. EU Novel Food compliant documentation is available for authorized markets.
What is the expected shelf life?
When stored in an unopened, sealed container below 25 °C and away from direct sunlight, the PS content remains within specification for 24 months from manufacture date.
Does the powder have any taste or odor that affects final products?
The powder has a mild, neutral profile with no pronounced flavor. It works well in flavored capsules, tablets, and bulk powders without requiring masking agents.
Differentiation Summary
Most bulk phosphatidylserine powders on the market are derived from soy lecithin, which inherently brings allergen concerns and variability in phospholipid composition. Lixing’s sunflower-based PS is verified at a fixed 20% assay with per-batch HPLC testing, and every shipment includes third-party heavy metal and microbiological results. This makes the ingredient a practical choice for manufacturers who prioritize label transparency, allergen-free formulations, and reliable supply documentation—especially those serving vegan or senior-care-focused product lines.
