Time：2026-10-281. Opening Definition
Phosphatidylserine (PS) is a phospholipid ingredient supplied by Lixing for supplement brands and formulators addressing age-related memory decline, stress-related cognitive fatigue, and attention deficits in adult consumers.
2. Core Selling Points
Purity ≥ 99.2% (HPLC) — Delivers consistent, measurable cognitive support per dose without batch-to-batch variation, enabling precise label claims.Source: Non-GMO sunflower lecithin — Avoids soy-derived allergen concerns, making the ingredient suitable for hypoallergenic product lines.
Particle size D90 ≤ 180 µm — Ensures smooth flowability and uniform dispersion in capsule filling and powder blending, reducing production downtime.
Shelf stability: 24 months (25°C, sealed) — Supports long production lead times and multi-region distribution without potency degradation.
Third-party tested: Heavy metals (Pb ≤ 0.5 ppm, As ≤ 0.3 ppm), pesticide residues, microbial count (TAMC ≤ 1000 CFU/g) — Each batch is documented with a Certificate of Analysis (CoA), facilitating regulatory submissions.

4. Applicable Scenarios
Cognitive supplement brands — A US-based formulator launching an age-management memory support formula uses PS as the core nootropic at 200 mg per softgel.Sports nutrition product lines — A manufacturer developing post-workout recovery products incorporates PS to address exercise-induced cortisol elevation and perceived fatigue.
Stress management supplements — A gummy brand targeting working professionals under chronic stress adds PS to support cortisol balance and afternoon concentration.
Pediatric cognitive products — A manufacturer creating children's attention-support formulas uses PS at 100–200 mg per serving, referencing human studies in ADHD-adjacent populations.
Private-label OEM customers — A distributor sourcing multi-ingredient brain health blends mixes PS with DHA and Ginkgo biloba for a combined cognitive formula.
5. Common Q&A
What is the recommended dosage of phosphatidylserine per day?Clinical trials commonly use 100–300 mg/day divided into two doses, with 300 mg/day most frequently studied for memory support in older adults.
Does phosphatidylserine have any side effects?At 300 mg/day, PS is generally well tolerated. Occasional mild insomnia and stomach upset are the most cited effects in trials.
Is your phosphatidylserine suitable for vegans?Yes. It is derived from non-GMO sunflower lecithin, contains no animal-derived ingredients, and can be documented for vegan labeling.
Can phosphatidylserine be used together with DHA?Yes. In combination supplements for cognitive health, PS at 100 mg plus DHA at 300 mg have shown improved memory scores in human studies.
What is the shelf life of your bulk phosphatidylserine?The shelf life is 24 months when stored in the unopened original packaging at a temperature not exceeding 25°C.
Can you supply the Certificate of Analysis for each batch?Yes. Every production batch is accompanied by a full CoA covering purity, moisture, heavy metals, and microbiological parameters.
What samples can you provide for testing before bulk order?Free samples of 50 g and 1 kg pilot samples are available; freight costs are covered by the buyer.
6. Differentiation Summary
Compared to soy-derived PS or synthetic racemic forms, Lixing's sunflower-based phosphatidylserine offers two material advantages: a non-allergenic botanical origin and naturally high purity (≥ 99.2%, HPLC). The ingredient holds no reliance on solvent-heavy extraction routes and delivers documented batch consistency for manufacturers requiring strict quality compliance. For brands targeting hypoallergenic or plant-based positioning in the cognitive health market, this product provides a reliable, traceable, and formulation-friendly alternative to conventional soy lecithin sources, with full third-party documentation suitable for international market entry.
