Procurement & delivery
Supply details confirmed by intended use, volume and target market
Phosphatidylserine is a phospholipid ingredient supplied in concentration grades rather than as one single pure small molecule. The current 70% COA reports PS 71.2% and follows QB/T 5821-2023; source and carrier should be confirmed for each grade. Compare the PS assay basis, source, carrier and documentation for each grade. A COA for a 70% lot does not qualify a 50% lot; confirm the exact grade before comparing price per unit of PS. Product image: AI-generated ingredient illustration; actual batch appearance is subject to the sample and COA.

PS and phosphatidic acid (PA) have been investigated together in lecithin-derived blends. A formulation screen can compare PS-only and PS+PA prototypes for phospholipid profile, oxidation, dispersibility, capsule fill and storage stability; confirm the PS source and PA specification before using the published blend as a benchmark.
Expand research and formulation notes +Collapse research and formulation notes −Development rationale: PS and phosphatidic acid (PA) have been investigated together in lecithin-derived blends. A formulation screen can compare PS-only and PS+PA prototypes for phospholipid profile, oxidation, dispersibility, capsule fill and storage stability; confirm the PS source and PA specification before using the published blend as a benchmark.
Evidence scope: A small randomized study evaluated a particular soy-lecithin PS+PA blend. Its findings cannot isolate PS's contribution and do not establish equivalence for a different source, 50%/70% grade, ratio, or finished product.
Pilot checks: Retain individual-ingredient, blend and carrier controls; check uniformity and post-process assays before packaged samples, documenting study formulations separately from new candidates.
2014 · Positive effects of soy lecithin-derived phosphatidylserine plus phosphatidic acid on memory, cognition, daily functioning, and mood in elderly patients with Alzheimer's disease and dementia. ↗Literature-Supported Research Directions
A 12-week randomized study of 120 older adults with memory complaints compared 300 or 600 mg/day of soy-derived phosphatidylserine with placebo. It reported no significant between-group differences across the measured cognitive outcomes. Source, composition and formulation in that study may differ from this 50% / 70% powder.

A six-month randomized study in 78 older Japanese adults with memory complaints reported that some memory-score changes were concentrated among participants with lower baseline scores; scores also rose in placebo participants. The result is population- and formulation-specific and is not a general efficacy finding for every phosphatidylserine grade.

The stated purity and batch result are shown separately. Confirm the method, dry-basis calculation and salt or hydrate form against the current COA.
Formulation work should confirm concentration, pH, light, moisture and hold-time controls for Phosphatidylserine 50% / 70%; suitability depends on the final format and market requirements.
The raw-material MOQ for PS 50% and 70% powders is 20 kg. The reference COAs for these grades list 20 kg/carton packaging; confirm the order packaging against the selected grade’s supply documentation. Compare active-PS cost using the respective lot COAs.
Compare the PS assay basis, source, carrier and documentation for each grade. A COA for a 70% lot does not qualify a 50% lot; confirm the exact grade before comparing price per unit of PS.
Phosphatidylserine (PS) powder is offered in 50% and 70% grades, each with its own specification and lot COA. Review source, other components and any carrier information in the grade-specific documentation. An assay percentage does not replace a composition declaration.
For PS 50% and 70%, review the grade’s assay specification, method and calculation basis, plus its matching lot COA, moisture and applicable contaminant results. Verify source, carrier or allergen requirements through separate declarations. One grade’s documents do not qualify another grade.
Identify the non-PS fraction through the exact grade’s composition statement and carrier documentation. A 50% or 70% label states the agreed PS assay; it does not identify the remaining components or establish carrier-free status.
On the same confirmed assay basis, divide powder price by the PS fraction. For nominal 50% and 70% grades, use P50/0.50 and P70/0.70, then assess source, carrier, processing, testing and delivery costs separately.
COA PGPS50-20260325 reports PS 53.9 g/100 g against ≥50 g/100 g and moisture 0.95 g/100 g. These results apply to that lot; request the COA for the material being offered.
Request the grade-specific extraction, separation, detector, reference standard, calibration and calculation basis. HPLC in a specification or a published research method does not by itself establish the full procedure used for the offered batch.
