Frequently Asked Questions
What is the standard concentration of phosphatidylserine powder?
The standard grade contains ≥20% phosphatidylserine measured by HPLC. Custom concentrations can be produced for specialized applications. This specification lets manufacturers match clinical study dosages while keeping capsule sizes manageable.
How much phosphatidylserine should be used per serving in clinical studies?
Most human trials use 100 mg of pure phosphatidylserine per day. To reach that dose with 20% powder, use 500 mg of our ingredient in each serving. Higher doses have also been tested for cognitive stress reduction.
Is Lixing Phosphatidylserine extracted with solvents?
No. We use a clear, solvent-free separation process on soybean lecithin. This preserves phospholipid integrity and avoids residual solvent risks, making the powder safer for sensitive populations and stricter regulatory markets.
Can you supply documentation for each batch?
Yes. Every shipment includes a COA covering HPLC purity, heavy metal content, microbial limits, and residual solvent data. These documents support raw material inspection and regulatory filing for global markets.
What is the minimum order quantity for bulk orders?
Sample orders start at 0.5 kg for formulation testing. Standard bulk packaging is 25 kg per drum, with full container loads available. We also offer smaller packaging for warehouse qualification.
Does this powder work for vegan supplement products?
Yes. It is derived from non-GMO soybean lecithin and contains no animal-derived excipients. The production line is dedicated to plant-based ingredients, so vegan labeling claims remain straightforward.
How should I store the ingredient after opening the drum?
Reseal the drum tightly and store at room temperature, below 25°C, in a dry area. Typical shelf life is 24 months if humidity remains below 35% RH. Avoid exposure to direct sunlight or high heat.
Can you custom blend Phosphatidylserine with other cognitive ingredients like DHA or alpha-GPC?
We offer mixing services with compatible excipients and actives. Custom ratios can be prepared and delivered with a unified COA. This simplifies downstream production and reduces your supplier management overhead.
Compared with generic lecithin powders or unstandardized phosphatidylserine extracts, Lixing provides verified ≥20% PS potency, full heavy-metal traceability, and batch documentation that supports regulatory filings in the United States and the European Union. The solvent-free process and plant-based origin meet clean-label expectations for modern supplement brands. This product is designed for manufacturers who prioritize consistent cognitive-health claims and need an ingredient that survives strict quality audits. If you produce supplements that promise measurable memory or focus benefits, this PS powder delivers a high level of standardization without the compliance uncertainty of lower-grade soy lecithin.
