Lixing High quality Phosphatidylserine Price
Time：2026-10-12Lixing Phosphatidylserine is a sunflower-derived, ≥90% pure phospholipid supplement designed for adults with age-related memory decline or stress-related cognitive fatigue, providing a 200–300 mg daily dose for recall support.
Core Selling Points
100 mg PS per capsule, standardized by HPLC to ≥90% purity: delivers the exact dose used in short-term memory research without requiring extra capsules. A 120-capsule bottle covers 60 days at the standard 2-capsule dose.Zero excipients – no magnesium stearate, silicon dioxide, or rice flour fillers: eliminates inert bulk that dilutes active content and lowers the risk of gastrointestinal irritation, a common complaint with dried-flow-agent formulations.
Soy-free, non-GMO sunflower lecithin source: avoids soy allergens and phytoestrogen exposure, making it suitable for people who cannot tolerate conventional soy-based PS.
Third-party tested for heavy metals and microbes: every batch publishes a certificate of analysis (COA) with lead < 0.1 ppm, cadmium < 0.05 ppm, and total plate count < 1000 CFU/g. The COA code is printed on each bottle for batch traceability.
24-month stability with 98.2% potency retention: accelerated aging tests confirm the PS remains above 90% purity through expiration when stored below 25°C, allowing bulk purchase without potency concerns.

Applicable Scenarios
Graduate students during exam study: Three capsules before a study block provides measurable improvements in delayed word recall and sustained attention, based on a 2001 placebo-controlled trial in Psychopharmacology (100–300 mg PS/day).Professionals under chronic work stress: A daily 200 mg PS intake has been shown to blunt cortisol spikes by about 20% during a 42-day stress protocol, translating to clearer problem-solving at the end of a demanding workday.
Adults 55+ with everyday memory lapses: An 8-week intervention with 300 mg/day PS improved daily forgetfulness scores in older adults, as reported in a systematic review of PS trials (Jorissen et al., 2001; Kato-Kataoka et al., 2010).
Athletes in high-volume training: A 2007 exercise study (JISSN) found 750 mg PS for 10 days reduced perceived muscle soreness and blunted cortisol responses during sport-specific stress, supporting recovery in intense training blocks.
Night-shift workers needing sustained alertness: In a simulated night-work protocol, 200 mg PS reduced reaction-time variability and improved performance on vigilance-based tasks, making it a plausible option for irregular shift schedules.
Common Questions
What is the current price range for Lixing Phosphatidylserine?
A 120-capsule bottle (100 mg per capsule) costs USD $28–$35 depending on retailer and promotion. At the standard daily dose of 2 capsules, a single bottle lasts 60 days, giving a monthly cost of approximately $14–$17.50. Per-capsule cost ranges from $0.23 to $0.29.
How quickly does phosphatidylserine work for memory?
In double-blind clinical trials, significant memory improvements appear after six to eight weeks of daily 200–300 mg supplementation. Some individuals report a subjective boost in clarity during the first week, but validated cognitive tests do not show statistically reliable separation from placebo before day 42. Plan for at least eight weeks.
Is a 100 mg dose enough?
For healthy adults, 100 mg twice daily has improved working memory in a placebo-controlled study. For age-related memory loss, clinical protocols typically use 300 mg/day, split into three doses. With this 100 mg capsule, take three capsules spread across meals to match those trials.
Can I open the capsules and mix them into food?
Yes, opening the capsules does not alter stability, but phosphatidylserine is fat-soluble. For proper absorption, mix the powder into a meal with at least 10 g of fat—such as yogurt, oatmeal with nuts, or a smoothie with almond butter. Avoid mixing into water or juice alone.
Does this product contain genetically engineered ingredients?
No. The sunflower lecithin is certified non-GMO, and the hypromellose capsule comes from plant cellulose with no genetic modification. The final product is also tested for GMO markers using PCR methodology, with results included in the batch COA.
How does per-capsule cost compare to bulk phosphatidylserine powder?
Bulk PS powder is often sold as a 50% concentrate mixed with maltodextrin, meaning you need 200 mg of powder to get 100 mg of PS. Lixing's capsule delivers 100 mg of pure PS directly; the effective pure-PS price is roughly $2.50 per gram, which is competitive with high-purity sunflower PS products and below many low-purity alternatives.
Differentiation Summary
Lixing Phosphatidylserine fills a specific niche among comparable supplements: high purity with an allergen-free source and documented testing. Unlike mainstream soy-based products that contain 50% PS mixed with carriers such as maltodextrin or rice flour, this capsule holds >90% PS with zero excipients. The sunflower-lecthin origin sidesteps soy allergen concerns and allows clean labeling. Price per effective milligram is competitive with generic PS pills when you recalculate for actual PS content. This makes Lixing a rational choice for older adults, students, and professionals who want a dose you can count without swallowing twice the filler.
