Lixing High quality Phosphatidylserine Light yellow or off-white fine powder
Time：2026-10-211. Product Definition
Lixing Phosphatidylserine (PS) is a sunflower-lecithin-derived raw ingredient designed for dietary supplement manufacturers and formulators seeking a high-purity, non-animal, allergen-free PS source that reduces regulatory risk and stabilizes raw material supply costs.
2. Core Selling Points
Purity 20% or 50% (HPLC) — Enables formulators to standardize finished products with measurable cognitive-health claims, reducing batch variability in capsule or tablet production.Sunflower-derived, not soybean- or animal-derived — Avoids common soy allergen concerns and fits vegan/pharma-compliant labeling in North America, the EU, and China.
Heavy-metal control (Pb ≤1.0 mg/kg, As ≤1.0 mg/kg, Cd ≤1.0 mg/kg) — Verified via third-party testing, facilitating smooth regulatory submissions and supplier audits for export brands.
Particle size ≥95% through 60 mesh — Improves powder flow and blendability when mixed with other nootropics or fillers, cutting production down-time.
Stable 24-month shelf life at sealed room temperature — Reduces supply-chain waste and supports predictable procurement planning.

4. Use Scenarios
Supplement factory commissioning a memory or focus ingredient: Use PS 50% to add a standardized active to your nootropic stack, leveraging existing labeling and claims.R&D team creating a new vegan cognitive-health blend: Replace soy-derived PS with sunflower PS to satisfy user demands for allergen-free and plant-based formulas.
Sports nutrition brand expanding into brain health: Add PS to a pre-workout or recovery powder for a pointed "mental clarity after exercise" benefit.
Procurement officer for a mid-size manufacturer: Secure a long-term bulk price for multiple batches, avoiding the spot-market volatility of pig-brain or soy-derived PS.
Global distributor scouting for a stable supply of bulk ingredients: Validate third-party heavy-metal reports and certificate-of-analysis to quickly onboard the product into your catalog.
5. Common FAQs
What is the supply price for bulk Phosphatidylserine?
Lixing quotes vary with purity (20% vs. 50%), total order volume, and delivery Incoterm. Volume orders of 25 kg or more get per-kg price tiers; special pricing is available for annual contracts.
Is this PS from animal brain or soybean?
No. Lixing uses sunflower lecithin as the only raw source, which makes the ingredient vegan-friendly and free from typical soy allergen issues.
What purity grades does Lixing provide?
Standard grades are 20% and 50% PS w/w, tested by HPLC. Custom purity is not offered for new customers because of lead-time constraints.
Do you supply a certificate of analysis (COA) for each batch?
Yes, every production lot ships with a COA covering purity, heavy metals, and microbial counts. Third-party lab results (SGS or Eurofins) are shared on request or with the packed parcel.
What is the minimum order quantity?
Standard MOQ is 25 kg per purity grade. For sample testing, 500 g and 1 kg samples are available at cost, but the sample charge is deducted from your first production order.
Does the powder contain any artificial mixers or excipients?
No excipients are added. The powder is pure concentrated PS compounds from sunflower lecithin. If flowability is required, you can blend with magnesium stearate in your own facility.
How long is the shelf life and what are the storage conditions?
Shelf life is 24 months from the date of manufacture when stored in unopened, sealed bags at room temperature (15–25°C) and below 65% relative humidity.
Can you guarantee a free-spec (phthalates, BP-free) quality for EU or MDR compliance?
Lixing checks for BPA and phthalates on major shipments and can include results in the COA, especially if the contracted specification includes them.
6. Differentiation Advantage
Compared with soy-derived PS (often non-allergen-labeled despite lower purity risk) and brain-derived PS (pet-sensitive and difficult to ship), Lixing offers a sunflower-based raw material set that combines high quantified purity with a stricter heavy-metal limit: Pb and As below 1 mg/kg, not just standard EU limits. It also solves two practical supplier problems ignored by smaller competitors: batch lab documentation is issued without extra fees, and wholesale price caps for annual purchasing are written into the contract, making it a better fit for mid-size manufacturers that need consistent backups for their own production schedules. Use Lixing Phosphatidylserine if your priority is to ship a clean crash-limiting ingredient with stable cost and reduced audit friction.
