Phosphatidylserine 51446-62-9 Powder Marke quotation
Time：2026-11-13Phosphatidylserine is a phospholipid supplement formulated for adults experiencing age-related memory decline, students under academic pressure, and professionals with high cognitive demands, addressing issues of forgetfulness, reduced concentration, and slower information recall.
Core Selling Points
100 mg per softgel, soy-derived Phosphatidylserine — Clinical studies suggest this dosage supports memory recall and attention span within 8–12 weeks of daily use, providing a measurable cognitive baseline without stimulant effects.≥99% purity, HPLC-verified — Each batch eliminates residual solvents and heavy metals to meet USP standards, ensuring consistent absorption and reducing gastrointestinal irritation commonly associated with lower-grade supplements.
Non-GMO sunflower lecithin base — Avoids soy allergens while maintaining the same phospholipid structure, making it suitable for individuals with soy sensitivities who still require cognitive support.
1,000 IU added Vitamin E (mixed tocopherols) — Prevents oxidation of the phosphatidylserine molecule during storage, extending shelf life to 24 months while preserving bioactivity, a detail often overlooked in competing formulations.
Third-party tested for heavy metals (≤0.1 ppm lead, ≤0.05 ppm cadmium) — Certificates of analysis issued per lot, providing traceability for quality-focused buyers.

Applicable Scenarios
Older adults (55+) tracking early memory lapses — Take 100–200 mg daily to support recall of names and daily tasks, as part of a routine cognitive health protocol.University students during exam periods — Supplement 200 mg daily with omega-3 to maintain sustained focus during 6-hour study sessions without caffeine crashes.
Working professionals in high-pressure roles — Use 100 mg before meetings requiring rapid decision-making, noting improved verbal fluency within 90 minutes of ingestion.
Athletes recovering from intense training — Incorporate 200 mg daily to reduce exercise-induced cortisol spikes, indirectly protecting hippocampal neurons from stress-related damage.
Individuals following ketogenic or plant-based diets — Since these diets often lack dietary phosphatidylserine, supplementing 100 mg daily restores baseline intake levels (approximately 100–150 mg dietary norm).
Common Faq
How long does phosphatidylserine take to work for memory improvement?Most users report measurable improvements in recall and focus after 8–12 weeks of consistent use, though some notice subtle changes within 2–3 weeks.
Can phosphatidylserine be taken with other nootropics like Bacopa or Ginkgo?Yes, combining phosphatidylserine with Bacopa monnieri or Ginkgo biloba is safe and often complementary, as they act via different pathways without known negative interactions.
Is 100 mg per day enough, or should I take more?For general cognitive maintenance, 100 mg daily suffices. For pronounced memory decline, clinical protocols often use 300–400 mg daily, divided into two doses.
Does this supplement cause insomnia if taken at night?Phosphatidylserine does not contain stimulants, but α wave enhancement may promote calmness. Taking it with dinner is safe; if you are sensitive, dose it in the morning.
Is Lixing's phosphatidylserine safe for long-term use?Published studies have assessed phosphatidylserine at 300–500 mg daily for up to 12 months with no significant adverse effects. Follow the label dose and consult a physician if on anticoagulants.
Can I take this if I have a soy allergy?Yes, our formula uses sunflower lecithin as the phosphatidylserine source, not soy. It is verified soy-free and suitable for individuals with soy sensitivities.
What is the difference between Phosphatidylserine and phosphatidylcholine?Phosphatidylserine is bound to L-serine and targets neuronal membrane integrity, while PC is a choline precursor for acetylcholine synthesis. They serve different cognitive functions and are not interchangeable.
How should I store the bottle to maintain potency?Keep it below 25°C, away from moisture and direct light. Refrigeration is not required but acceptable if the container is sealed tightly.
Compared to generic phosphatidylserine supplements on the market, Lixing's formulation distinguishes itself through three pillars: purity verification beyond label claims (HPLC-tested ≥99%), excipient transparency (no hidden fillers or allergens), and oxidation resistance built into the formula (mixed tocopherols). Brands like NOW Foods and Jarrow Formulas offer similar dosages, but many rely on soy-derived phosphatidylserine with limited third-party contaminant disclosure. Lixing's target user is the evidence-driven buyer—someone who reads labels critically, requests CoAs, and prefers a soy-free allergen profile without negotiating on dose accuracy. If your priority is a phosphatidylserine supplement with documented purity, clean excipients, and stable bioactivity over a 24-month shelf life, this product matches that criterion more closely than most soy-based alternatives in the same price bracket.
