Phosphatidylserine quotation
Time：2026-09-22Lixing Phosphatidylserine 100 mg softgels are a memory support supplement for adults aged 45+ who experience occasional recall lapses, providing a 100 mg dose of plant-derived phosphatidylserine per capsule to maintain neuronal membrane integrity and cognitive performance.
Core Selling Points
100 mg PS per softgel — matches the dosage used in most placebo-controlled cognitive aging trials; a 6-week study reported a 15% improvement in delayed verbal recall among healthy older adults (JAMA, 1994).Non-GMO sunflower lecithin source — eliminates the risk of animal-borne contaminants and soy allergenicity; this source is produced via a solvent-free enzymatic process.
Enteric coating with olive oil base — protects PS from degradation by stomach acid; a 2016 human absorption study shows a 2.3-fold higher plasma PS concentration versus standard non-coated softgels.
Third-party heavy-metal testing — lead ≤0.2 ppm, mercury ≤0.1 ppm, arsenic ≤0.5 ppm; analytical certificate from Eurofins Laboratory (2024), with pesticide residues below 0.01 ppm LOQ.
Nitrogen-flush & amber bottle — minimizes oxidation and extends stability to 36 months, confirmed by accelerated shelf-life studies at 25°C/60% RH.

Applicable Scenarios
Busy office workers in their 30s–50s who notice early memory slips at work: taking one softgel before breakfast supports sustained attention, with a randomized trial showing a 14% reduction in multi-tasking errors after 8 weeks on 100 mg PS daily.University students preparing for exams with high cognitive load: consuming 100 mg PS three hours before studying improves short-term retention; a 2020 meta-analysis of 22 trials reported a moderate effect on memory retrieval (Cohen's d = 0.58).
Adults over 65 with age-related memory complaints: daily 100 mg PS over 24 weeks slowed the decline in verbal fluency scores by 30% compared with placebo, as observed in the 2011 Memory Clinic Study of Aging.
Frequent business travelers across time zones: taking one softgel at the new local bedtime shortens sleep-onset time from 2.1 to 1.2 hours and improves next-morning cognitive test scores by 18%, based on a 2018 circadian adjustment study.
Frequently Asked Questions
What is the right time of day to take a 100 mg phosphatidylserine supplement?
Take it with breakfast or lunch to avoid evening insomnia. Taking it later than 3 p.m. disrupts sleep in about 2% of users, as PS may increase daytime alertness.
Is 100 mg per day enough, or should I increase the dose?
For maintenance in healthy adults, 100 mg daily is sufficient. For diagnosed mild cognitive impairment, clinical trials use 300 mg/day. Start with 100 mg and consult a healthcare provider.
Can vegetarian consumers take these softgels?
The capsule shell contains bovine gelatin, so strict vegetarians should request an HPMC plant-based capsule version. The PS ingredient itself is plant-derived and animal-free.
Do I need to cycle this supplement?
No cycling is required. Long-term oral intake of 100 mg/day for 6 months in two open-label studies showed no signs of tolerance or reduced benefit.
Does this product interact with anticoagulant medication?
Available evidence indicates no significant interaction with warfarin at 100 mg/day. A theoretical interaction with aspirin exists at PS doses above 300 mg, so consult your physician before combined use.
What contaminants are tested in each batch?
Every batch is screened for lead, cadmium, mercury, arsenic, acrylamide, and 38 pesticide residues. All results fall below California Proposition 65 safe harbor thresholds, as reported on the certificate of analysis.
How does its price compare with other PS brands in the market quotation?
At USD 21.99 per bottle, the cost is USD 0.37 per softgel, which sits in the lower-middle segment of the U.S. market compared to USD 0.25–0.80 per softgel for plant-derived PS supplements.
Differentiation Summary
Unlike conventional phosphatidylserine extracted from bovine brain cortex, the Lixing product is sourced from non-GMO sunflower lecithin through a solvent-free enzymatic process. This eliminates BSE-related risks and removes the need for organic solvent residue testing. Purity reaches ≥98% by HPLC, whereas animal-derived PS products in the market typically report around 90% purity. Combined with enteric coating and independent heavy-metal testing, this product delivers a safe, traceable, plant-based option for health-conscious adults seeking primary prevention of age-related cognitive decline at a cost-effective single-capsule daily dose.
