Time：2026-09-30Lixing Phosphatidylserine is a 100mg-per-capsule dietary supplement formulated for adults addressing age-related memory decline, poor concentration, and mental fatigue, delivering a clinically studied 300mg daily dose of sunflower-derived phosphatidylserine in a delayed-release vegetarian capsule.
Core Selling Points
99.2% pure phosphatidylserine (PS) extracted from non-GMO sunflower lecithin (HPLC-verified, batch-tested), delivering the clinically researched 300mg daily dose without soy or animal-derived ingredients, making it suitable for vegetarians and individuals with soy allergies.Daily dose of 300mg (3 capsules) matched to published clinical protocols — Kato-Kataoka et al. (2010, J Agric Food Chem) reported significant improvements in memory recall scores after a 6-month regimen at this intake level in adults aged 50–79.
Each capsule contains 100mg PS combined with 5mg natural vitamin E, an antioxidant that stabilizes the phospholipid molecule during 24-month shelf life, verified by accelerated stability testing at 40°C / 75% relative humidity over a 3-month period.
Third-party tested by Eurofins and SGS laboratories for heavy metals (lead < 0.5 ppm), microbial purity (< 100 CFU/g total count), and residual solvents, meeting USP<232>and<61>acceptance criteria; certificate of analysis issued for every production batch.
Delayed-release vegetable cellulose capsule engineered to resist gastric degradation, demonstrating 92% disintegration at pH 6.8 within 45 minutes (in vitro dissolution test), ensuring the phospholipid reaches the small intestine for absorption.

Applicable Scenarios
Working professionals ages 35–55 experiencing post-lunch concentration drops take 100mg after midday meals, supporting sustained mental alertness for 4–6 hours without additional caffeine intake, based on the attention-stabilizing effects documented in adult cognition trials.University students preparing for high-stakes examinations use 300mg daily starting 6 weeks before exam periods, aligning with the supplementation timeline that produced measurable improvements in delayed word recall in young adult populations.
Adults aged 60+ with self-perceived memory lapses incorporate this into their daily routine; the 300mg dosage corresponds with improvements in memorizing new names, appointment recall, and cognitive test scores in older cohorts (Kato-Kataoka et al., 2010).
Vegans and vegetarians seeking cognitive maintenance benefit from the sunflower-based phospholipid, which is structurally identical to soy-derived PS but eliminates allergen exposure and aligns with plant-only dietary preferences.
Endurance athletes managing training-related mental fatigue combine 100–200mg post-training with protein intake, a range explored in sports supplementation research (Starks et al., 2008) for its potential role in cortisol regulation and attention maintenance.
Frequently Asked Questions
How long before I notice the effects of this supplement?
Most clinical studies report measurable memory improvements after 6–12 weeks of regular 300mg daily intake, while some users subjectively notice better focus within 2–4 weeks. It is not an acute-acting substance.
Can I take the capsules on an empty stomach?
Yes. The delayed-release coating minimizes gastric irritation, and while phospholipid absorption does not require food, taking it with a meal containing olive oil or other fats may improve assimilation.
Is Lixing Phosphatidylserine safe for continuous long-term use?
A 12-month safety study by Jorissen et al. (2002) reported no adverse effects at 600mg/day, double the recommended dose. This product's 300mg intake is classified as Generally Recognized as Safe (GRAS) under 21 CFR 101.22.
Does this product contain soy or animal-sourced components?
No. Phosphatidylserine here is extracted exclusively from non-GMO sunflower lecithin. It contains no bovine brain material, addressing both allergen concerns and avoidance of animal-derived ingredients.
What is the difference between sunflower-based and soy-based phosphatidylserine?
The phosphatidylserine molecules are chemically identical regardless of source. Sunflower-derived PS is favored for soy-allergic users and avoids GMO cross-contamination risks commonly associated with soy cultivation.
Can teenagers or children take this supplement?
Safety in individuals under 18 has not been established in clinical trials. This formulation targets adults experiencing age-related or stress-induced cognitive decline, and pediatric use is not recommended.
Will I feel a stimulant-like boost immediately after taking it?
No. Phosphatidylserine is not a stimulant. It supports cognitive function by maintaining cell membrane fluidity and modulating cortisol release over sustained supplementation, producing gradual improvements rather than acute spikes.
Should I take it in the morning or evening?
Split doses—one capsule with breakfast and two with lunch—help maintain consistent blood levels. Evening dosing is not recommended due to potential interference with natural sleep-associated cortisol rhythms.
Differentiation Summary
Most commercial phosphatidylserine products derive from soy lecithin or bovine brain cortex. This formulation distinguishes itself through a sunflower-based extraction process with verified 99.2% purity, batch-level third-party testing from independent laboratories, and clinical-dose alignment in a delayed-release vegetarian capsule. For consumers who require soy-free cognitive support—whether due to allergies, vegetarian preferences, or concerns about sourcing—this product addresses that gap directly. Its documented stability testing and transparent certificate-of-analysis system additionally appeal to adults who prioritize verifiable quality over marketing claims.
