Applicable Scenarios
A university student preparing for final exams takes 300 mg daily to improve working memory consolidation and reduce mental fatigue during intensive study periods.A 55-year-old professional experiencing occasional forgetfulness uses 400 mg/day to support sustained attention during complex project management tasks.
A healthy adult following a plant-based diet chooses this soy-derived PS as a vegan-friendly alternative to animal-derived phospholipid supplements.
A night-shift worker who needs to maintain alertness during irregular hours incorporates 200 mg in the morning to mitigate sleep-deprivation-related cognitive slowing.

FAQ
1. How is high purity Phosphatidylserine different from regular lecithin supplements?
Phosphatidylserine is a specific phospholipid present in neuronal membranes at low concentrations; regular lecithin contains mostly phosphatidylcholine and less than 3% PS. This product isolates PS to ≥98%, allowing targeted cognitive dosing.
2. What is the recommended daily dosage for memory support?
Clinical studies use 100–500 mg/day. For mild age-related memory complaints, 300 mg/day is the most common effective dose, typically split as 100 mg three times daily.
3. Can high purity Phosphatidylserine be taken with other supplements?
Yes, PS is fat-soluble; taking it with a meal containing dietary fats improves absorption. It shows no known negative interactions with omega-3 fatty acids, B vitamins, or creatine.
4. Is this product safe for vegetarians?
Yes, it is produced from non-GMO soy lecithin via enzymatic conversion, containing no animal-derived ingredients. Suitable for vegetarian and vegan capsule formulations.
5. How long does it take to see noticeable cognitive effects?
Controlled trials report measurable improvements in memory recall and processing speed after 6–12 weeks of consistent daily intake. Acute effects are not expected from a single dose.
6. Does Phosphatidylserine cause any side effects?
At recommended doses, the most common side effect is mild gastrointestinal discomfort in sensitive individuals, which can be reduced by taking it with food. No serious adverse events have been documented in clinical literature.
7. What is the difference between soy-derived and sunflower-derived Phosphatidylserine?
Soy-derived PS is the most extensively researched source, with clinical cognitive studies using soy lecithin extraction. Sunflower-derived PS is also available but has fewer human trials; both offer high purity when properly processed.
8. How should this raw powder be stored?
Keep in a sealed, moisture-proof container below 25°C, away from direct sunlight. Avoid refrigeration due to condensation risk. Under correct storage, potency remains ≥95% for 24 months.
Summary
Compared to common PS powders that report 10–20% purity or are blended with other phospholipids, Lixing's high purity Phosphatidylserine provides a concentrated 98% HPLC-verified active ingredient with documented heavy metal and microbial compliance. Its enzyme-converted, non-GMO soy origin avoids the contamination risks of bovine-derived PS while maintaining a full amino acid profile for those with dietary restrictions. This product is best suited for supplement manufacturers and health-conscious consumers who require a traceable, high-purity raw material for consistent cognitive support formulations, rather than generic low-potency blends.
